NEW QUESTION # 16
An administrator of a company has concerns about upgrading the access layer switches. The users rely heavily on wireless and VoIP telephony. Which is the best recommendation to ensure a short downtime for the users during upgrading the access layer switches?
- A. Install AOS-CX 6300 or 6400 switches with always-on POE
- B. Install the in-service software upgrade (ISSU) feature with clustering enabled
- C. Implement VSF on the AOS-CX access switches
- D. Implement VSX on the AOS-CX access switches
Answer: A
Explanation:
The key is to reduce the impact. VSF or not will have same impact when the switch reboots. But if the switch support always on poe then at least the POE clients will be ready before the switch finish booting up. If you dont have always on POE, then the poe clients will reboot AFTER the switch boots up.
NEW QUESTION # 17
An administrator in a company of 349 users has a pair of AOS-CX switches with connections to external networks. Both switches are configured for OSPF. The administrator wants to import external routes on both switches, but assigns different seed metrics to the routes, as well as imports them as external type-1 routes.
What is the best way for the administrator to accomplish this?D18912E1457D5D1DDCBD40AB3BF70D5D
- A. Create a classifier policy with the correct route type and metrics
- B. Create a route map with the correct route type and metrics
- C. Define the route type and metrics in the OSPF process
- D. Define a class and policy map with the correct route type and metrics
Answer: B
NEW QUESTION # 18
What is correct regarding the operation of VSX and multicasting with PIM-SM routing configured?
- A. Each VSX peers runs PIM and builds its own group database. One of the VSX peers is elected as the designated router (DR) to forward multicast streams to a receiver VLAN
- B. Each VSX peers runs PIM and creates a shared group database. One of the VSX peers is elected as the designated router (DR) to forward multicast streams to a receiver VLAN
- C. Each VSX peers runs PIM and builds its own group database. Both VSX peers can forward multicast streams to receivers in a VLAN, achieving load sharing
- D. Each VSX peers runs PIM and creates a shared group database. Both VSX peers can forward multicast streams to receivers in a VLAN, achieving load sharing
Answer: A
Explanation:
"both VSX switches as a PIM Designate Router (DR). One node is the actual DR, the other node is the proxy DR." "Only the actual DR performs multicast routing and forward traffic destined to groups to its downstream VLANs in the data-path." https://www.arubanetworks.com/techdocs/AOS-CX/10.07/HTML/5200-7888/Content/Chp_Pre_tra_loss/ip-mul-rou-10.htm
NEW QUESTION # 19
Examine the following AOS-CX switch configuration:
Which statement correctly describes what is allowed for traffic entering interface 1/1/3?
- A. IP traffic from 10.1.11.0/24 is allowed to access 10.1.110.0/24
- B. IP traffic from 10.1.12.0/24 is allowed to access 172.0.1.0/23
- C. IP traffic from 10.0.11.0/24 is allowed to access 10.1.12.0/24
- D. Traffic from 10.0.12.0/24 will generate a log record when accessing 10.0.11.0/24
Answer: C
Explanation:
People seem to be confused by inverted mask/wildcard masks. They would be correct for Cisco switches, but AOS-CX does NOT use wildcard masks; "AOX-CX switches do not support wildcard masks - only prefixes or subnet masks - when created ACEs." Cisco: 255.0.255.0 = xx.123.xx.123 AOS-CX: 255.0.255.0 = 123.xx.123.xx
NEW QUESTION # 20
Examine the network exhibit.
A company has a guest implementation for wireless and wired access. Wireless access is implemented through a third-party vendor. The company is concerned about wired guest traffic traversing the same network as the employee traffic. The network administrator has established a GRE tunnel between AOS-CX switches where guests are connected to a routing switch in the DMZ.
Which feature should the administrator implement to ensure that the guest traffic is tunneled to the DMZ while the employee traffic is forwarded using OSPF?
- A. Classifier policies
- B. Policy-based routing (PBR)
- C. User-based tunneling (UBT)
- D. OSPF route maps using the "set metric" command
Answer: B
NEW QUESTION # 21
An administrator is supporting a network with the access layer consisting of AOS-CX 6300 and 6400 switches. The administrator needs to quickly deploy Aruba IAPs and security cameras in the network, ensuring that the correct QoS and VLAN settings are dynamically applied to the switch ports.

- A. Device profiles
- B. Voice VLANs
- C. Change of authorization
- D. Dynamic segmentation
Answer: D
