  What is a requirement for the switch to be a potential IGMP querier on that VLAN?

  A. The switch must run PIM-SM or PIM-DM on that VLAN.

  B. The switch must have an IP address on that VLAN.

  C. The switch must have IGMP fast leave disabled globally.

  D. The switch must have at least one IGMP group configured on it manually.

  Correct Answer: B

• Question 152:

  Refer to the exhibit.

  

  Switch-1 runs BGP. What should the network administrator do to permit Switch-1 to establish a neighbor relationship with Router-1?

  A. Configure 192.168.1.2 as a neighbor manually within the BGP context.

  B. Specify 192.168.1.0/30 with the network command in the BGP context.

  C. Enable BGP on VLAN 100.

  D. Set the BGP AS number to 46501.

  Correct Answer: A

• Question 153:

  An AOS-Switch needs to be configured to support tunneled node in role-based mode. The Mobility Controller administrators tell the switch administrators that the AOS-Switch will integrate with a cluster of Mobility Controllers. The cluster virtual IP address is 10.1.1.10.

  How should switch administrator integrate the AOS-Switch with the cluster?

  A. Double-check the settings with the Mobility Controller administrators because the planned configuration is incomplete with the switch settings.

  B. Configure the virtual IP address as the tunneled-node-server address, tunneled node will work, but the clustering features will not provide redundancy.

  C. Configure the virtual IP address as the tunneled-node-server address. The switch will automatically learn controller IP addresses to which to tunnel various traffic.

  D. Configure the virtual IP address for the primary tunneled-node-server and an actual controller IP address for the backup tunneled-node-server in order to receive redundancy.

  Correct Answer: B

• Question 154:

  Refer to the exhibits. Exhibit 1.

  

  Exhibit 2.

  

  The VoIP phone connects, authenticates successfully, and is dynamically assigned to tagged VLAN 6. The endpoint connected to the phone does not authenticate but starts to send untagged traffic.

  How does the switch handle this traffic?

  A. It forwards the traffic in VLAN 5.

  B. It relays the traffic to the RADIUS server for authentication.

  C. It forwards the traffic in VLAN 6.

  D. It drops the traffic.

  Correct Answer: B

• Question 155:

  Which benefit is provided by MD5 authentication for BGP?

  A. It validates that BGP messages arrive from an authorized device.

  B. It verifies that received BGP routes have valid next hop IP addresses.

  C. It enables users to authenticate to a server across BGP AS boundaries.

  D. It protects BGP routing information from eavesdroppers.

  Correct Answer: A

• Question 156:

  Two AOS-Switches are directly interconnected. The network administrator wants to prevent broadcast storms and other Layer 2 issues that could occur if there is physical damage to a cable.

  Which technology should the administrator implement on the connected switch interfaces?

  A. MAC Lockdown

  B. Bidirectional Forwarding Detection (BFD)

  C. Spanning Tree Root Guard

  D. Unidirectional Link Detection (UDLD)

  Correct Answer: D

• Question 157:

  Refer to the exhibit.

  

  The routing switches shown in the exhibit run OSPF on the links between each other. The commander in the Switch-1 VSF fabric goes down. Traffic is disrupted for several seconds.

  What should a network administrator do to support a faster failover in a similar situation?

  A. Configure echo mode BFD on the VLAN that connects Switch-1 and Switch-2.

  B. Add VRRP on the VLAN between Switch-1 and Switch-2.

  C. Configure graceful restart, or nonstop OSPF, on Switch-1 and Switch-2, with a proper timer.

  D. Create a redundant virtual link between Switch-1 and Switch-2.

  Correct Answer: A

• Question 158:

  Refer to the exhibit.

  

  The network administrator enables DHCP snooping globally and on VLAN 2. An additional step is mandatory for DHCP snooping to operate correctly and for clients to receive DHCP settings.

  What is the additional mandatory step?

  A. Define trk1 as a trusted DHCP port.

  B. Define an authorized DHCP server.

  C. Enable ARP protection.

  D. Define edge ports as untrusted DHCP ports.

  Correct Answer: D

• Question 159:

  A network administrator configures connection rate filtering on interface 1 with the throttle action. Device 1 crosses the threshold and triggers the action.

  What does the switch do?

  A. It temporarily drops all IP traffic from Device 1 only.

  B. It temporarily drops all IP traffic on interface 1.

  C. It drops all IP traffic from Device 1 until the host is manually unblocked.

  D. It drops all IP traffic on interface 1 until the interface is manually unblocked.

  Correct Answer: A

• Question 160:

  What must an OSPF router do to ensure nonstop routing should a standby member take over as commander when the original VSF commander fails?

  A. It must run the shortest path first algorithm.

  B. It must participate in a new election for the Designated Router.

  C. It must initiate a graceful restart.

  D. It must re-establish adjacency with its Designated Router.

  Correct Answer: C
