NEW QUESTION # 12
What are two valid options when configuring the scope of a distributed firewall rule? (Choose two.)
- A. Group
- B. Tier-1 Gateway
- C. DFW
- D. Segment
- E. Segment Port
Answer: A,D
Explanation:
C) Segment. This is correct. A segment is a logical construct that represents a layer 2 broadcast domain and a layer 3 subnet in NSX. A segment can be used to group and connect virtual machines, containers, or bare metal hosts that belong to the same application or service. A segment can also be used as the scope of a distributed firewall rule, which means that the rule will apply to all the traffic that enters or exits the segment12 E) Group. This is correct. A group is a logical construct that represents a collection of objects in NSX, such as segments, segment ports, virtual machines, IP addresses, MAC addresses, tags, or security policies. A group can be used to define dynamic membership criteria based on various attributes or filters. A group can also be used as the scope of a distributed firewall rule, which means that the rule will apply to all the traffic that matches the group membership criteria32
NEW QUESTION # 13
Which CLI command shows syslog on NSX Manager?
- A. /var/log/syslog/syslog.log
- B. show log manager follow
- C. get log-file syslog
- D. get log-file auth.lag
Answer: C
Explanation:
According to the VMware NSX CLI Reference Guide, this CLI command shows the syslog messages on the NSX Manager node. You can use this command to view the system logs for troubleshooting or monitoring purposes.
The other options are either incorrect or not available for this task. get log-file auth.log is a CLI command that shows the authentication logs on the NSX Manager node, not the syslog messages. /var/log/syslog/syslog.log is not a CLI command, but a file path that may contain syslog messages on some Linux systems, but not on the NSX Manager node. show log manager follow is not a valid CLI command, as there is no show log command or manager option in the NSX CLI.
NEW QUESTION # 14
An administrator has deployed 10 Edge Transport Nodes in their NSX Environment, but has forgotten to specify an NTP server during the deployment.
What is the efficient way to add an NTP server to all 10 Edge Transport Nodes?
- A. Use the CU on each Edge Node
- B. Use a PowerCU script
- C. Use Transport Node Profile
- D. Use a Node Profile
Answer: D
Explanation:
A node profile is a configuration template that can be applied to multiple NSX Edge nodes or transport nodes at once. A node profile can include settings such as NTP server, DNS server, syslog server, and so on1. By using a node profile, an administrator can efficiently configure or update the network settings of multiple NSX Edge nodes or transport nodes in a single operation2. The other options are incorrect because they are either not efficient or not supported. Using the CLI on each Edge node would require manual and repetitive commands for each node, which is not efficient. Using a Transport Node Profile would not work, because a Transport Node Profile is used to configure the NSX-T Data Center components on a transport node, such as the transport zone, the N-VDS, and the uplink profiles3. Using a PowerCLI script might work, but it would require writing and testing a custom script, which is not as efficient as using a built-in feature like a node profile.
NEW QUESTION # 15
Sort the rule processing steps of the Distributed Firewall. Order responses from left to right.
Answer:
Explanation:
Explanation
The correct order of the rule processing steps of the Distributed Firewall is as follows:
* Packet arrives at vfilter connection table. If matching entry in the table, process the packet.
* If connection table has no match, compare the packet to the rule table.
* If the packet matches source, destination, service, profile and applied to fields, apply the action defined.
* If the rule table action is allow, create an entry in the connection table and forward the packet.
* If the rule table action is reject or deny, take that action.
This order is based on the description of how the Distributed Firewall works in the web search results1. The first step is to check if there is an existing connection entry for the packet in the vfilter connection table, which is a cache of flow entries for rules with an allow action. If there is a match, the packet is processed according to the connection entry. If there is no match, the packet is compared to the rule table, which contains all the security policy rules. The rules are evaluated from top to bottom until a match is found. The match criteria include source, destination, service, profile and applied to fields. The action defined by the matching rule is applied to the packet. The action can be allow, reject or deny. If the action is allow, a new connection entry is created for the packet and the packet is forwarded to its destination. If the action is reject or deny, the packet is dropped and an ICMP message or a TCP reset message is sent back to the source.
NEW QUESTION # 16
A customer has a network where BGP has been enabled and the BGP neighbor is configured on the Tier-0 Gateway. An NSX administrator used the get gateways command to retrieve this Information:
Which two commands must be executed to check BGP neighbor status? (Choose two.)
- A. sa-nexedge-01(tier0_sr> get bgp neighbor
- B. vrf 4
- C. sa-nexedge-01(tier1_sr> get bgp neighbor
- D. vrf 1
- E. sa-nexedge-01(tier1_dr)> get bgp neighbor
- F. vrf 3
Answer: A,B
Explanation:

NEW QUESTION # 33
A company Is deploying NSX micro-segmentation in their vSphere environment to secure a simple application composed of web. app, and database tiers.
The naming convention will be:
* WKS-WEB-SRV-XXX
* WKY-APP-SRR-XXX
* WKI-DB-SRR-XXX
What is the optimal way to group them to enforce security policies from NSX?
- A. Create an Ethernet based security policy.
- B. Use Edge as a firewall between tiers.
- C. Do a service insertion to accomplish the task.
- D. Group all by means of tags membership.
Answer: D
Explanation:
The answer is C. Group all by means of tags membership.
Tags are metadata that can be applied to physical servers, virtual machines, logical ports, and logical segments in NSX. Tags can be used for dynamic security group membership, which allows for granular and flexible enforcement of security policies based on various criteria1 In the scenario, the company is deploying NSX micro-segmentation to secure a simple application composed of web, app, and database tiers. The naming convention will be:
WKS-WEB-SRV-XXX
WKY-APP-SRR-XXX
WKI-DB-SRR-XXX
The optimal way to group them to enforce security policies from NSX is to use tags membership. For example, the company can create three tags: Web, App, and DB, and assign them to the corresponding VMs based on their names. Then, the company can create three security groups: Web-SG, App-SG, and DB-SG, and use the tags as the membership criteria. Finally, the company can create and apply security policies to the security groups based on the desired rules and actions2 Using tags membership has several advantages over the other options:
It is more scalable and dynamic than using Edge as a firewall between tiers. Edge firewall is a centralized solution that can create bottlenecks and performance issues when handling large amounts of traffic3 It is more simple and efficient than doing a service insertion to accomplish the task. Service insertion is a feature that allows for integrating third-party services with NSX, such as antivirus or intrusion prevention systems. Service insertion is not necessary for basic micro-segmentation and can introduce additional complexity and overhead.
It is more flexible and granular than creating an Ethernet based security policy. Ethernet based security policy is a type of policy that uses MAC addresses as the source or destination criteria. Ethernet based security policy is limited by the scope of layer 2 domains and does not support logical constructs such as segments or groups.
To learn more about tags membership and how to use it for micro-segmentation in NSX, you can refer to the following resources:
