How is voice traffic prioritized correctly on AOS-CX switches?

  1. By defining device profiles with QOS settings
  2. By placing it in the strict priority queue
  3. By implementing voice VLANs
  4. By implementing weighted fair queueing (WFQ)

Answer(s): B



An administrator is replacing the current access switches with AOS-CX switches. The access layer switches must authenticate user and networking devices connecting to them. Some devices support no form of authentication, and some support 802.1X. Some ports have a VoIP phone and a PC connected to the same port, where the PC is connected to the data port of the phone and the phone's LAN port is connected to the switch.
Which statement is correct about this situation?

  1. 802.1X must be configured to work in fallback mode
  2. Device fingerprinting is required for authentication
  3. The client-limit setting for port access needs to be changed
  4. Device mode should be implemented

Answer(s): C

Explanation:

fallback mode if for the radius part; client limit is for multiple authent on one port (ie phone + pc)

From doc :
aaa port-access authenticator <port-list> client-limit <1-32>

Used after executing aaa port-access authenticator <port-list> to convert authentication from port- based to user-based. Specifies user-based 802.1X authentication and the maximum number of 802.1X-authenticated client sessions allowed on each of the ports in <port-list>. If a port currently has no authenticated client sessions, the next authenticated client session the port accepts determines the untagged VLAN membership to which the port is assigned during the session. If another client session begins later on the same port while an earlier session is active, the later session will be on the same untagged VLAN membership as the earlier session.



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?

  1. OSPF route maps using the "set metric" command
  2. Policy-based routing (PBR)
  3. User-based tunneling (UBT)
  4. Classifier policies

Answer(s): B

Explanation:

Guest traffic can be routed with PBR to use GRE tunnels that terminate in the DMZ.



An administrator has an AOS-CX switch configured with:
router ospf 1
area 0
area 1 stub no-summary
It is the only ABR for area 1. The switch has the appropriate adjacencies to routing switches in areas 0 and 1.
The current routes in each area are:
Area 0: 5 routes (LSA Type 1 and 2)
Area 1: 10 routes (LSA Type 1 and 2)
External routes: 2 (LSA Type 5)
Based on the above configuration, how many OSPF routes will routing switches see in Area 1?

  1. 15
  2. 6
  3. 11
  4. 12

Answer(s): C



A network administrator is managing a network that deploys a multicast service. The administrator has multiple streams successfully being routed by PIM-DM in the network. The administrator then adds a new stream with a destination address of 239.0.0.1. However, clients who have not joined the stream are receiving it.
What should the administrator do to fix this problem?

  1. Verify that IGMP is enabled between the switches connecting the multicast source and receivers
  2. Change the destination multicast address to 239.1.1.1
  3. Define the 239.0.0.1 stream on the rendezvous point (RP)
  4. Define the 239.0.0.1 stream on the PIM candidate bootstrap router

Answer(s): B

Explanation:

MAC/IP overlap. 239.0.0.1 would be the same MAC for 224.0.0.1. 224.0.0.0/24 is always flooded over every port.
