An administrator has an aggregation layer of 8325CX switches configured as a VSX pair. The administrator is concerned that when OSPF network changes occur, the aggregation switches will respond to the changes slowly, and this will affect network connectivity, especially VoIP calls, in the connected access layer switches.
What should the administrator do on the aggregation layer switches to alleviate this issue?D18912E1457D5D1DDCBD40AB3BF70D5D

• A.Implement route aggregation
• B.Implement bidirectional forwarding detection (BFD)
• C.Reduce the hello and dead interval timers
• D.Implement graceful restart

A network engineer is using NetEdit to manage AOS-CX switches. The engineer notices that a lot of thirdparty VoIP phones are showing up in the NetEdit topology. The engineer deletes these, but they are automatically rediscovered by NetEdit and added back in.
What should the administrator do to solve this problem?

• A.Disable the RESTful API on all the VoIP phones
• B.Disable SSH access on all the VoIP phones
• C.Disable LLDP globally on the AOS-CX switches where phones are connected
• D.Change the VoIP phone SNMP community string to something unknown by NetEdit

A company has implemented 802.1X authentication on AOS-CX access switches, where two ClearPass servers are used to implement AAA.
Each switch has the two servers defined. A network engineer notices the following command configured on the AOS-CX switches:
radius-server tracking user-name monitor password plaintext aruba123
What is the purpose of this configuration?

• A.Implement replay protection for AAA messages
• B.Define the account to implement downloadable user roles
• C.Speed up the AAA authentication process
• D.Define the account to implement change of authorization

How does PIM build the IP multicast routing table to route traffic between a multicast source and one or more receivers9

• A.It uses the unicast routing table and reverse path forwarding (RPF )
• B.It uses IGMP and calculates a shortest path tree (SPT).
• C.It uses the shortest path first (SPF) algorithm derived from link state protocols.
• D.It uses the Bellman-Ford algorithm derived from distance vector protocols
