• Question 121:

  A network administrator applies port security to a port with the send-alarm action.

  What does the switch do if it detects traffic from an unauthorized MAC address on the port?

  A. It disables the port, but sends no SNMP trap.

  B. It forwards the traffic, and it logs an event.

  C. It blocks the traffic, but sends no SNMP trap.

  D. It blocks the traffic, and it sends an SNMP trap.

  Correct Answer: A

• Question 122:

  Refer to the exhibits.

  

  The network administrator enters the commands shown in Exhibit 2, and Switch-1 and Switch-2 exchange keepalive messages.

  What is the expected behavior if Switch-1 later fails to receive keepalive messages from Switch-2?

  A. Switch-1 disables interface 1 for 10 seconds, and then re-enables it. The same process repeats twice. If the issue persists, the switch disables the interface permanently.

  B. After two consecutive missed keep-alive packets, Switch-1 disables interface 1, and the interface stays disabled until the issue is fixed.

  C. After two consecutive missed keep-alive packets, Switch-1 sends SNMP traps, and Link 1 stays up until the issue is fixed.

  D. Switch-1 disables interface 1 for 10 seconds and then re-enables it. The interface continues to be re-enabled and disabled every 10 seconds until the issue is fixed.

  Correct Answer: B

• Question 123:

  Two AOS-Switches connect on VLAN 10 in OSPF Area 1, which is defined as a stub area on both.

  Which mismatch can cause OSPF routers to lose adjacency?

  A. The administrator adds the backbone area to just one of the routers.

  B. The administrator enables graceful restart, or nonstop switching, on just one of the routers.

  C. The administrator enables jumbo frames on VLAN 10 on just one of the routers.

  D. The administrator adds the no-summary option to Area 1 on just one of the routers.

  Correct Answer: B

• Question 124:

  Refer to the exhibit.

  

  Switch-1 is an AOS-switch that is operating at factory default settings for QoS and has type of service disabled. It receives a frame with 802.1p value 5 on trk1, on VLAN 2.

  How does the switch treat the frame when it forwards it on TRK2?

  A. It forwards it with higher than normal priority and 802.1p 0.

  B. It forwards it with normal priority and 802.1p 0.

  C. It forwards it with normal priority and 802.1p 5

  D. It forwards it with higher than normal priority and 802.1p 5.

  Correct Answer: B

• Question 125:

  The security policy for a company requires that switches use SNMPv3 and accept all read-only SNMPv2c messages. The network administrator enables SNMPv3.

  Which additional action should the network administrator take to comply with this policy?

  A. Disabled SNMPv3 inform timeouts.

  B. Enable SNMPv3 only operation.

  C. Enable SNMPv3 restricted mode.

  D. Disable SNMPv1/v2c.

  Correct Answer: C

• Question 126:

  Refer to the exhibit.

  

  Every switch in the exhibit will route traffic. The company requires a topology in which failover for switch-toswitch links is exclusively handled by the routing protocol and occurs as quickly as possible.

  Which topology should the administrator use?

  A. A

  B. B

  C. C

  D. D

  Correct Answer: B

• Question 127:

  Refer to the exhibits. Exhibit 1

  

  Exhibit 2 Network administrators are alerted to high interface utilization on a switch by a management solution. They examine the utilization on the uplink interfaces several times an hour during problem times. The exhibit shows output typical of times of congestion. The administrators want to allocate bandwidth fairly and reduce congestion on the uplinks.

  

  What could help meet these requirements?

  A. a per-queue rate limit on interfaces 1 and 2

  B. an outbound rate limit on each edge port

  C. a broadcast rate limit on each edge port

  D. an outbound rate limit on interfaces 1 and 2

  Correct Answer: C

• Question 128:

  A company has AOS-switches, Aruba ClearPass, and Aruba AirWave. A network administrator needs to find the source of a performance issue that often occurs at the start of the day and early in the afternoon.

  Which action is likely to give the administrator the most useful information for the investigation?

  A. Access the Network Device view on ClearPass.

  B. Use the configuration audit tool on AirWave.

  C. View the current running config on each switch.

  D. View usage patterns on the switches on AirWave.

  Correct Answer: A

• Question 129:

  Refer to the exhibits. Exhibit 1

  

  Exhibit 2

  

  Exhibit 1 shows the topology for the network. The network administrator sees the log entries shown in Exhibit 2. Which type of failure is indicated?

  A. A link between Switch-1 and Switch-2 went down. BFD detected the lost connectivity and behaved as expected.

  B. Graceful restart helper was not enabled on Switvh-2, so BFD was unable to operate correctly, and the session was taken down.

  C. A hardware issue caused a unidirectional link; BFD detected the issue at Layer 2 and prevented a broadcast storm.

  D. BFD was set up incorrectly on Switch-2, so it caused Switch-2 to lose adjacency with Switch-1 rather than repair the session.

  Correct Answer: D

• Question 130:

  Network administrators need to configure a BGP neighbor on an AOS-Switch. What defines the neighbor as an iBGP neighbor?

  A. It has BGP synchronization enabled.

  B. It has an AS number in the range of 64512 to 64535.

  C. Its update source is set to a private company IP address.

  D. Its remote-AS is the same as the AOS-Switch BGP AS.

  Correct Answer: D
