• Question 385:

  In a routed access hierarchical campus design, the access-to-distribution Layer 2 uplink trunks are replaced with Layer 3 point-to-point routed links. Why is it recommended that VLANs are confined on a single access switch rather than span across multiple access switches?

  A. to allow for better convergence time

  B. to prevent the occurrence of Layer 2 loops

  C. to allow for fault isolation

  D. to prevent routing black holes

  Correct Answer: D

• Question 386:

  Which two benefits does using virtual PortChannel technology provide? (Choose two).

  A. vPC eliminates spanning-tree blocked ports.

  B. vPC allows a dual-homed server to operate in active-standby mode.

  C. vPC significantly reduces latency.

  D. vPC uses all uplink bandwidth.

  E. vPC supports VLAN-based load balancing.

  Correct Answer: AD

• Question 387:

  Refer to the exhibit.

  

  RTR 1 uses RTR 2 as the primary WAN exit point. When a failure occurs in the link connected to RTR 2 LAN, it takes about 40 seconds for RTR 1 to use the backup path via RTR 3.

  Which two mechanisms can be used independently to improve the failure detection time to 1 second or less when RTR 1 failover to RTR3? (Choose two.)

  A. Configure EEM on RTR 2.

  B. Change OSPF throttling timer.

  C. Use BFD with OSPF between RTR 1 and RTR 2.

  D. Use BFD with OSPF between RTR 2 and RTR 3.

  E. Tune OSPF fast hello on all the routers.

  Correct Answer: CE

• Question 388:

  When you design a network that uses IPsec, where can you reduce MTU to avoid network fragmentation?

  A. on both ends of the TCP connection

  B. on the side closest to the client

  C. on the side closest to the server

  D. in the WAN

  Correct Answer: A

• Question 389:

  Which Designated Intermediate System selection option is valid when deploying IS-IS in a broadcast medium that connects two networking devices as a point-to-point network type?

  A. There is no DIS selection on point-to-point network types.

  B. The router with the highest interface IP address is selected as the DIS.

  C. The router with the lowest interface priority address is selected as the DIS.

  D. The router with the highest loopback IP address is selected as the DIS.

  E. The router with the lowest interface MAC address is selected as the DIS.

  Correct Answer: A

• Question 390:

  To meet specific business requirements, QoS-marked traffic must be sent over a dedicated link.

  Which technology fulfills this requirement?

  A. MPLS

  B. Q-in-Q tunneling

  C. policy-based routing

  D. EIGRP with modified metrics

  Correct Answer: C
