NEW QUESTION # 89
What is one difference between EAP-Tunneled Layer security (EAP-TLS) and Protected EAP (PEAP)?
- A. EAP-TLS creates a TLS tunnel for transmitting user credentials securely while PEAP protects user credentials with TKIP encryption.
- B. EAP-TLS requires the supplicant to authenticate with a certificate, hut PEAP allows the supplicant to use a username and password.
- C. EAP-TLS begins with the establishment of a TLS tunnel, but PEAP does not use a TLS tunnel as part of Its process
- D. EAP-TLS creates a TLS tunnel for transmitting user credentials, while PEAP authenticates the server and supplicant during a TLS handshake.
Answer: B
Explanation:
EAP-TLS and PEAP both provide secure authentication methods, but they differ in their requirements for client-side authentication. EAP-TLS requires both the client (supplicant) and the server to authenticate each other with certificates, thereby ensuring a very high level of security. On the other hand, PEAP requires a server-side certificate to create a secure tunnel and allows the client to authenticate using less stringent methods, such as a username and password, which are then protected by the tunnel. This makes PEAP more flexible in environments where client-side certificates are not feasible.

What is a difference between radius and TACACS+?
- A. RADIUS uses TCP for Its connection protocol, while TACACS+ uses UDP tor its connection protocol.
- B. RADIUS uses Attribute Value Pairs (AVPs) in its messages, while TACACS+ does not use them.
- C. RADIUS combines the authentication and authorization process while TACACS+ separates them.
- D. RADIUS encrypts the complete packet, white TACACS+ only offers partial encryption.
Answer: C
Explanation:
RADIUS and TACACS+ are both protocols used for networking authentication, but they handle the processes of authentication and authorization differently. RADIUS (Remote Authentication Dial-In User Service) combines authentication and authorization into a single process, whereas TACACS+ (Terminal Access Controller Access-Control System Plus) separates these processes. This separation in TACACS+ allows more flexible policy enforcement and better control over commands a user can execute. This difference is well-documented in various network security resources, including Cisco's technical documentation and security protocol manuals.

What is one way that WPA3-PerSonal enhances security when compared to WPA2-Personal?
- A. WPA3-Personai prevents eavesdropping on other users' wireless traffic by a user who knows the passphrase for the WLAN.
- B. WPA3-Personal is more complicated to deploy because it requires a backend authentication server
- C. WPA3-Personai is more resistant to passphrase cracking Because it requires passphrases to be at least 12 characters
- D. WPA3-Perscn3i is more secure against password leaking Because all users nave their own username and password
Answer: A
Explanation:
WPA3-Personal enhances security over WPA2-Personal by implementing individualized data encryption. This feature, known as Wi-Fi Enhanced Open, provides each user's session with a unique encryption key, even if they are using the same network passphrase. This prevents an authenticated user from eavesdropping on the traffic of other users on the same network, thus enhancing privacy and security.

NEW QUESTION # 95
What is an Authorized client, as defined by AOS Wireless Intrusion Prevention System (WIP)?
- A. A client that is NOT on the WIP blacklist
- B. A client that has successfully authenticated to an authorized AP and passed encrypted traffic
- C. A client that is on the WIP whitelist
- D. A client that has a certificate issued by a trusted Certification Authority (CA)
Answer: B
Explanation:
The AOS Wireless Intrusion Prevention System (WIP) in an AOS-8 architecture (Mobility Controllers or Mobility Master) is designed to detect and mitigate wireless threats, such as rogue APs and unauthorized clients. WIP classifies clients and APs based on their behavior and status in the network.
Authorized Client Definition: In the context of WIP, an "Authorized" client is one that has successfully authenticated to an authorized AP (an AP managed by the MC and part of the company's network) and is actively passing encrypted traffic. This typically means the client has completed 802.1X authentication (e.g., in a WPA3-Enterprise network) or PSK authentication (e.g., in a WPA3-Personal network) and is communicating securely with the AP.
Option D, "A client that has successfully authenticated to an authorized AP and passed encrypted traffic," is correct. This matches the WIP definition of an Authorized client: the client must authenticate to an AP that is classified as "Authorized" (i.e., part of the company's network) and must be passing encrypted traffic, indicating a secure connection (e.g., using WPA3 encryption).
Option A, "A client that is on the WIP whitelist," is incorrect. WIP does not use a client whitelist for classification. The AP whitelist is used to authorize APs, not clients. Client classification (e.g., Authorized, Interfering) is based on their authentication status and connection to authorized APs.
Option B, "A client that has a certificate issued by a trusted Certification Authority (CA)," is incorrect. While a certificate might be used for 802.1X authentication (e.g., EAP-TLS), WIP does not classify clients as Authorized based on their certificate status. The classification depends on successful authentication to an authorized AP and encrypted traffic.
Option C, "A client that is NOT on the WIP blacklist," is incorrect. WIP does use blacklisting (e.g., for clients that violate security policies), but being "not on the blacklist" does not make a client Authorized. A client must actively authenticate to an authorized AP and pass encrypted traffic to be classified as Authorized.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"In the Wireless Intrusion Prevention (WIP) system, an 'Authorized' client is defined as a client that has successfully authenticated to an authorized AP and is passing encrypted traffic. An authorized AP is one that is managed by the Mobility Controller and part of the company's network. For example, a client that completes 802.1X authentication to an authorized AP using WPA3-Enterprise and sends encrypted traffic is classified as Authorized." (Page 414, WIP Client Classification Section) Additionally, the HPE Aruba Networking Security Guide notes:
"WIP classifies clients as 'Authorized' if they have authenticated to an authorized AP and are passing encrypted traffic, indicating a secure connection. Clients that are not authenticated or are connected to rogue or neighbor APs are classified as 'Interfering' or other categories, depending on their behavior." (Page 78, WIP Classifications Section)

NEW QUESTION # 96
A company has AOS-CX switches deployed in a two-tier topology that uses OSPF routing at the core.
You need to prevent ARP poisoning attacks. To meet this need, what is one technology that you could apply to user VLANs on access layer switches? (Select two.)
- A. BPDU guard (protection)
- B. BPDU filtering
- C. DHCPv4 snooping
- D. OSPF passive interface
- E. ARP inspection
Answer: C,E
Explanation:
The scenario involves AOS-CX switches in a two-tier topology (access and core layers) using OSPF routing at the core. The goal is to prevent ARP poisoning attacks on user VLANs at the access layer switches, where end-user devices connect. ARP poisoning (also known as ARP spoofing) is an attack where a malicious device sends fake ARP messages to associate its MAC address with the IP address of another device (e.g., the default gateway), allowing the attacker to intercept traffic.
ARP Inspection (Dynamic ARP Inspection, DAI): This feature prevents ARP poisoning by validating ARP packets against a trusted database of IP-to-MAC bindings. On AOS-CX switches, ARP inspection uses the DHCP snooping binding table to verify that ARP messages come from legitimate devices. If an ARP packet does not match the binding table, it is dropped.
DHCPv4 Snooping: This feature protects against rogue DHCP servers and builds a binding table of legitimate IP-to-MAC mappings by snooping DHCP traffic. The binding table is used by ARP inspection to validate ARP packets. DHCP snooping must be enabled before ARP inspection can function effectively, as it provides the trusted data for validation.
Option A, "ARP inspection," is correct. ARP inspection (DAI) directly prevents ARP poisoning by ensuring that ARP packets are legitimate, making it a key technology for this purpose.
Option B, "OSPF passive interface," is incorrect. OSPF passive interface is used to prevent OSPF from sending routing updates on specific interfaces, typically to reduce routing protocol traffic on user-facing interfaces. It does not prevent ARP poisoning, which is a Layer 2 attack.
Option C, "BPDU guard (protection)," is incorrect. BPDU guard protects against spanning tree protocol (STP) attacks by disabling a port if it receives BPDUs (e.g., from an unauthorized switch). It does not address ARP poisoning, which is unrelated to STP.
Option D, "DHCPv4 snooping," is correct. DHCP snooping is a prerequisite for ARP inspection, as it builds the binding table used to validate ARP packets. It also protects against rogue DHCP servers, which can indirectly contribute to ARP poisoning by assigning incorrect IP addresses.
Option E, "BPDU filtering," is incorrect. BPDU filtering prevents a port from sending or receiving BPDUs, which can be used to protect against STP attacks, but it does not prevent ARP poisoning.
The HPE Aruba Networking AOS-CX 10.12 Security Guide states:
"To prevent ARP poisoning attacks on user VLANs, enable Dynamic ARP Inspection (DAI) on access layer switches. DAI validates ARP packets against the DHCP snooping binding table to ensure they come from legitimate devices. Use the command ip arp inspection vlan <vlan-list> to enable DAI on the specified VLANs. DHCP snooping must be enabled first with dhcp-snooping and dhcp-snooping vlan <vlan-list> to build the binding table used by DAI." (Page 145, ARP Inspection and DHCP Snooping Section) Additionally, the guide notes:
"DHCP snooping and ARP inspection work together to protect against Layer 2 attacks like ARP poisoning. DHCP snooping builds a trusted database of IP-to-MAC bindings, which ARP inspection uses to filter out malicious ARP packets." (Page 146, Best Practices Section)

NEW QUESTION # 97
What is a correct guideline for the management protocols that you should use on AOS-CX switches?
- A. Make sure that HTTPS is disabled and use SSH instead.
- B. Make sure that Telnet is disabled and use TFTP instead.
- C. Make sure that SSH is disabled and use HTTPS instead.
- D. Make sure that Telnet is disabled and use SSH instead.
Answer: D
Explanation:
AOS-CX switches support various management protocols for administrative access, such as SSH, Telnet, HTTPS, and TFTP. Security best practices for managing network devices, including AOS-CX switches, emphasize using secure protocols to protect management traffic from eavesdropping and unauthorized access.
Option B, "Make sure that Telnet is disabled and use SSH instead," is correct. Telnet is an insecure protocol because it sends all data, including credentials, in plaintext, making it vulnerable to eavesdropping. SSH (Secure Shell) provides encrypted communication for remote management, ensuring that credentials and commands are protected. HPE Aruba Networking recommends disabling Telnet and enabling SSH for secure management access on AOS-CX switches.
Option A, "Make sure that SSH is disabled and use HTTPS instead," is incorrect. SSH and HTTPS serve different purposes: SSH is for CLI access, while HTTPS is for web-based management. Disabling SSH would prevent secure CLI access, which is not a recommended practice. Both SSH and HTTPS should be enabled for secure management.
Option C, "Make sure that Telnet is disabled and use TFTP instead," is incorrect. TFTP (Trivial File Transfer Protocol) is used for file transfers (e.g., firmware updates), not for management access like Telnet or SSH. TFTP is also insecure (no encryption), so it's not a suitable replacement for Telnet.
Option D, "Make sure that HTTPS is disabled and use SSH instead," is incorrect. HTTPS is used for secure web-based management and should not be disabled. Both HTTPS and SSH are secure protocols and should be used together for different management interfaces (web and CLI, respectively).
The HPE Aruba Networking AOS-CX 10.12 Security Guide states:
"For secure management of AOS-CX switches, disable insecure protocols like Telnet, which sends data in plaintext, and use SSH instead. SSH provides encrypted communication for CLI access, protecting credentials and commands from eavesdropping. Use the command no telnet-server to disable Telnet and ssh-server to enable SSH. Additionally, enable HTTPS for web-based management with https-server to ensure all management traffic is encrypted." (Page 195, Secure Management Protocols Section) Additionally, the HPE Aruba Networking Security Best Practices Guide notes:
"A key guideline for managing AOS-CX switches is to disable Telnet and enable SSH for CLI access. Telnet is insecure and should not be used in production environments, as it transmits credentials in plaintext. SSH ensures secure remote management, and HTTPS should also be enabled for web access."

NEW QUESTION # 98
Your company policies require you to encrypt logs between network infrastructure devices and Syslog servers. What should you do to meet these requirements on an ArubaOS-CX switch?
- A. Set up RadSec and then enable Syslog as a protocol carried by the RadSec tunnel.
- B. Specify the Syslog server with the UDP option and then add an CPsec tunnel that selects Syslog.
- C. Specify the Syslog server with the TLS option and make sure the switch has a valid certificate.
- D. Specify a priv key with the Syslog settings that matches a priv key on the Syslog server.
Answer: C
Explanation:
To ensure secure transmission of log data over the network, particularly when dealing with sensitive or critical information, using TLS (Transport Layer Security) for encrypted communication between network devices and syslog servers is necessary:
Secure Logging Setup: When configuring an ArubaOS-CX switch to send logs securely to a Syslog server, specifying the server with the TLS option ensures that all transmitted log data is encrypted.
Additionally, the switch must have a valid certificate to establish a trusted connection, preventing potential eavesdropping or tampering with the logs in transit.
Other Options:
Option B, Option C, and Option D are less accurate or applicable for directly encrypting log data between the device and Syslog server as specified in the company policies.
NEW QUESTION # 99
A company has HPE Aruba Networking Mobility Controllers (MCs), HPE Aruba Networking campus APs, and AOS-CX switches. The company plans to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to classify endpoints by type. The company is contemplating the use of ClearPass's TCP fingerprinting capabilities.
What is a consideration for using those capabilities?
- A. ClearPass admins will need to provide the credentials of an API admin account to configure on HPE Aruba Networking devices.
- B. AOS-CX switches do not offer the support necessary for CPPM to use TCP fingerprinting on wired endpoints.
- C. You will need to mirror traffic to one of CPPM's span ports from a device such as a core routing switch.
- D. TCP fingerprinting of wireless endpoints requires a third-party Mobility Device Management (MDM) solution.
Answer: C
Explanation:
HPE Aruba Networking ClearPass Policy Manager (CPPM) uses TCP fingerprinting as a passive profiling method to classify endpoints by analyzing TCP packet headers (e.g., TTL, window size) to identify the operating system (e.g., Windows, Linux). The company in this scenario has Mobility Controllers (MCs), campus APs, and AOS-CX switches, and wants to use CPPM's TCP fingerprinting capabilities for endpoint classification.
TCP Fingerprinting: This method requires CPPM to receive TCP traffic from endpoints. Since CPPM is not typically inline with network traffic, the traffic must be mirrored to CPPM for analysis. This is often done using a SPAN (Switched Port Analyzer) port or mirror port on a switch or controller.
Option A, "You will need to mirror traffic to one of CPPM's span ports from a device such as a core routing switch," is correct. For CPPM to perform TCP fingerprinting, it needs to see the TCP traffic from endpoints. This is typically achieved by mirroring traffic from a core routing switch (or another device like an MC) to a SPAN port on the CPPM server. For example, on an AOS-CX switch, you can configure a mirror session with the command mirror session 1 destination interface <CPPM-port> source vlan <vlan-id> to send traffic to CPPM. This is a key consideration for enabling TCP fingerprinting.
Option B, "ClearPass admins will need to provide the credentials of an API admin account to configure on HPE Aruba Networking devices," is incorrect. TCP fingerprinting does not require API credentials. It is a passive profiling method that analyzes mirrored traffic, and no API interaction is needed between CPPM and Aruba devices for this purpose.
Option C, "AOS-CX switches do not offer the support necessary for CPPM to use TCP fingerprinting on wired endpoints," is incorrect. AOS-CX switches support mirroring traffic to CPPM (e.g., using a mirror session), which enables CPPM to perform TCP fingerprinting on wired endpoints. The switch does not need to perform the fingerprinting itself; it only needs to send the traffic to CPPM.
Option D, "TCP fingerprinting of wireless endpoints requires a third-party Mobility Device Management (MDM) solution," is incorrect. TCP fingerprinting is a built-in capability of CPPM and does not require an MDM solution. For wireless endpoints, the MC can mirror client traffic to CPPM (e.g., using a datapath mirror), allowing CPPM to perform TCP fingerprinting.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"TCP fingerprinting requires ClearPass to receive TCP traffic from endpoints for analysis. A key consideration is that you must mirror traffic to one of ClearPass's SPAN ports from a device such as a core routing switch or Mobility Controller. For example, on an AOS-CX switch, configure a mirror session with mirror session 1 destination interface <CPPM-port> source vlan <vlan-id> to send traffic to ClearPass for TCP fingerprinting." (Page 248, TCP Fingerprinting Section) Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:
"For ClearPass to perform TCP fingerprinting on wireless endpoints, the Mobility Controller can mirror client traffic to ClearPass using a datapath mirror. For wired endpoints, an AOS-CX switch can mirror traffic to ClearPass's SPAN port, enabling TCP fingerprinting without requiring additional support on the switch itself."

NEW QUESTION # 100
You have deployed a new HPE Aruba Networking Mobility Controller (MC) and campus APs (CAPs). One of the WLANs enforces 802.1X authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM). When you test connecting the client to the WLAN, the test fails. You check ClearPass Access Tracker and cannot find a record of the authentication attempt. You ping from the MC to CPPM, and the ping is successful.
What is a good next step for troubleshooting?
- A. Check CPPM Event Viewer.
- B. Check connectivity between CPPM and a backend directory server.
- C. Renew CPPM's RADIUS/EAP certificate.
- D. Reset the user credentials.
Answer: A
Explanation:
In this scenario, a new HPE Aruba Networking Mobility Controller (MC) and campus APs (CAPs) are deployed, with a WLAN configured for 802.1X authentication using HPE Aruba Networking ClearPass Policy Manager (CPPM) as the RADIUS server. A client test fails, and no record of the authentication attempt appears in ClearPass Access Tracker. However, a ping from the MC to CPPM is successful, confirming basic network connectivity between the MC and CPPM.
The absence of a record in Access Tracker indicates that CPPM did not receive the RADIUS authentication request from the MC, or the request was rejected at a low level before being logged in Access Tracker. Access Tracker typically logs all RADIUS authentication attempts (successful or failed), so the lack of a record suggests a configuration or connectivity issue at the RADIUS level.
Option C, "Check CPPM Event Viewer," is correct. The CPPM Event Viewer logs system-level events, including RADIUS-related errors that might not appear in Access Tracker. For example, if the MC's IP address is not configured as a Network Access Device (NAD) in CPPM, or if the shared secret between the MC and CPPM does not match, CPPM may reject the RADIUS request before it reaches Access Tracker. The Event Viewer will log such errors (e.g., "RADIUS authentication attempt from unknown NAD"), providing insight into why the request was not processed.
Option A, "Renew CPPM's RADIUS/EAP certificate," is incorrect because the issue is that CPPM did not receive or process the authentication request (no record in Access Tracker). If there were a certificate issue (e.g., an expired or untrusted certificate), the request would still reach CPPM, and Access Tracker would log a failure with a certificate-related error.
Option B, "Check connectivity between CPPM and a backend directory server," is incorrect because the issue occurs before CPPM processes the authentication request. If CPPM cannot contact a backend directory server (e.g., Active Directory), the authentication attempt would still be logged in Access Tracker with a failure reason related to the directory server.
Option D, "Reset the user credentials," is incorrect because the issue is not related to the user's credentials. The authentication request never reached CPPM, so the credentials were not evaluated.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"If an authentication attempt does not appear in Access Tracker, it indicates that the RADIUS request was not received by ClearPass or was rejected at a low level before being logged. The Event Viewer (Monitoring > Event Viewer) should be checked for system-level errors, such as 'RADIUS authentication attempt from unknown NAD' or shared secret mismatches. For example, if the Network Access Device (NAD) IP address of the Mobility Controller is not configured in ClearPass, or if the shared secret does not match, the request will be dropped, and an error will be logged in the Event Viewer." (Page 301, Troubleshooting RADIUS Issues Section) Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:
"When troubleshooting 802.1X authentication issues, verify that the Mobility Controller can communicate with the RADIUS server. If a ping is successful but no authentication records appear in the RADIUS server's logs (e.g., ClearPass Access Tracker), check the RADIUS server's system logs (e.g., ClearPass Event Viewer) for errors related to NAD configuration or shared secret mismatches."

NEW QUESTION # 102
What is a reason to set up a packet capture on an HPE Aruba Networking Mobility Controller (MC)?
- A. You want the MC to analyze wireless clients' traffic at a lower level, so that the AOS firewall can control the traffic based on application.
- B. The company wants to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to profile devices and needs to receive HTTP User-Agent strings from the MC.
- C. You want the MC to analyze wireless clients' traffic at a lower level, so that the AOS firewall can control Web traffic based on the destination URL.
- D. The security team believes that a wireless endpoint connected to the MC is launching an attack and wants to examine the traffic more closely.
Answer: D
Explanation:
Packet captures on an HPE Aruba Networking Mobility Controller (MC) are a powerful troubleshooting and analysis tool, allowing administrators to capture and analyze network traffic at various levels (e.g., control plane or data plane). The MC supports packet captures for both wired and wireless traffic, which can be filtered based on criteria such as IP address, MAC address, or port.
Option A, "The security team believes that a wireless endpoint connected to the MC is launching an attack and wants to examine the traffic more closely," is correct. Packet captures are commonly used in security investigations to analyze the traffic of a specific endpoint suspected of malicious activity. For example, if a wireless client is suspected of launching an attack (e.g., a DoS attack or data exfiltration), a packet capture on the MC can capture the client's traffic (filtered by MAC or IP address) for detailed analysis, helping the security team identify the nature of the attack.
Option B, "The company wants to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to profile devices and needs to receive HTTP User-Agent strings from the MC," is incorrect. While CPPM can use HTTP User-Agent strings for device profiling, this is typically achieved by mirroring HTTP traffic to CPPM (e.g., using a datapath mirror on the MC), not by setting up a packet capture. Packet captures are for manual analysis, not for feeding data to CPPM.
Option C, "You want the MC to analyze wireless clients' traffic at a lower level, so that the AOS firewall can control Web traffic based on the destination URL," is incorrect. The AOS firewall on the MC can control traffic based on applications or services (e.g., using deep packet inspection, DPI), but it does not support URL-based filtering directly. URL filtering typically requires an external solution (e.g., a web proxy or firewall). Packet captures are not used to enable URL-based control by the firewall.
Option D, "You want the MC to analyze wireless clients' traffic at a lower level, so that the AOS firewall can control the traffic based on application," is incorrect. The AOS firewall can already perform application-based control using DPI (if enabled), without requiring a packet capture. Packet captures are for manual analysis, not for enabling firewall functionality.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
"Packet captures on the Mobility Controller are useful for troubleshooting and security investigations. For example, if the security team suspects that a wireless endpoint is launching an attack, you can set up a packet capture on the MC's data plane to capture the endpoint's traffic. Use the command packet-capture datapath <filter> (e.g., filter by the client's MAC address) to capture the traffic, which can then be analyzed to identify malicious activity." (Page 515, Packet Capture Section) Additionally, the HPE Aruba Networking Security Guide notes:
"Packet captures are a critical tool for security teams to investigate potential attacks. By capturing traffic from a specific wireless client suspected of malicious behavior, administrators can analyze the packets to determine the nature of the attack, such as a DoS attack or unauthorized data exfiltration."

NEW QUESTION # 104
Which is a correct description of a Public Key Infrastructure (PKI)?
- A. Root Certification Authorities (CAs) primarily sign certificates, and Intermediate Certification Authorities (CAs) primarily validate signatures.
- B. A user must manually choose to trust a root Certification Authority (CA) certificate, or the root CA certificate must be installed on the device as trusted.
- C. A device uses Intermediate Certification Authorities (CAs) to enable it to trust root CAs that are different from the root CA that signed its own certificate.
- D. A user must manually choose to trust intermediate and end-entity certificates, or those certificates must be installed on the device as trusted in advance.
Answer: B
Explanation:
Public Key Infrastructure (PKI) relies on a trusted root Certification Authority (CA) to issue certificates.
Devices and users must trust the root CA for the PKI to be effective. If a root CA certificate is not pre-installed or manually chosen to be trusted on a device, any certificates issued by that CA will not be inherently trusted by the device.

What is a benefit of Protected Management Frames (PMF). sometimes called Management Frame Protection (MFP)?
- A. PMF ensures trial traffic between APs and Mobility Controllers (MCs) is encrypted.
- B. PMF protects clients from DoS attacks based on forged de-authentication frames
- C. PMF helps to protect APs and MCs from unauthorized management access by hackers.
- D. PMF prevents hackers from capturing the traffic between APs and Mobility Controllers.
Answer: B
Explanation:
Protected Management Frames (PMF), also known as Management Frame Protection (MFP), is designed to protect clients from denial-of-service (DoS) attacks that involve forged de-authentication and disassociation frames. These attacks can disconnect legitimate clients from the network. PMF provides a way to authenticate these management frames, ensuring that they are not forged, thus enhancing the security of the wireless network.

What is a correct use case for using the specified certificate file format?
- A. using a PKCS12 file to install a certificate plus its private key on a device
- B. using a PKCS7 file to install a certificate plus and its private key on a device
- C. using a PEM file to install a binary encoded certificate on a device
- D. using a PKCS7 file to install a binary encoded private key on a device
Answer: A
Explanation:
The correct use case for using the specified certificate file format is option B, using a PKCS12 file to install a certificate along with its private key on a device. PKCS12 is a binary format for storing a certificate chain and private key in a single encrypted file. PEM files are Base64 encoded certificate files and are typically used for storing certificates, not private keys, and PKCS7 is used for certificate chains without the private key.

Refer to the exhibit.
This Aruba Mobility Controller (MC) should authenticate managers who access the Web Ul to ClearPass Policy Manager (CPPM) ClearPass admins have asked you to use RADIUS and explained that the MC should accept managers' roles in Aruba-Admin-Role VSAs Which setting should you change to follow Aruba best security practices?
- A. Clear the MSCHAP check box
- B. Disable local authentication
- C. Change the default role to "guest-provisioning"
- D. Change the local user role to read-only
Answer: B
Explanation:
For following Aruba best security practices, the setting you should change is to disable local authentication.
When integrating with an external RADIUS server like ClearPass Policy Manager (CPPM) for authenticating administrative access to the Mobility Controller (MC), it is a best practice to rely on the external server rather than the local user database. This practice not only centralizes the management of user roles and access but also enhances security by leveraging CPPM's advanced authentication mechanisms.

How does the ArubaOS firewall determine which rules to apply to a specific client's traffic?
- A. The firewall applies the rules in policies associated with the client's wlan
- B. The firewall applies every rule that includes the dent's IP address as the source.
- C. The firewall applies thee rules in policies associated with the client's user role.
- D. The firewall applies every rule that includes the client's IP address as the source or destination.
Answer: C
Explanation:
The ArubaOS firewall determines which rules to apply to a specific client's traffic based on the rules in policies associated with the client's user role. User roles are a fundamental part of ArubaOS and the firewall policies they encompass. These roles contain policies that dictate permissions and restrictions for network traffic. When a client authenticates, it is assigned a role, and the firewall enforces the rules defined within that role for the client's traffic.
