  A. Two Resilient Ethernet Protocol segments can be connected redundantly at two points. One connection will be blocked, using the Spanning Tree Protocol defined in IEEE 802.1D.

  B. UniDirectional Link Detection Protocol can be enabled on Resilient Ethernet Protocol interfaces to detect unidirectional failures.

  C. The guaranteed convergence recovery time is less than 50 ms for the local segment.

  D. A Resilient Ethernet Protocol segment is limited to a maximum of seven devices.

  E. VLAN load balancing for optimal bandwidth usage is supported in any Resilient Ethernet Protocol segment.

  Correct Answer: BE

• Question 633:

  Refer to the exhibit.

  

  If IEEE 802.1w is in use for this network design, what are two locations where spanningtree root can be placed to ensure the least-disruptive Layer 2 failover for clients within VLANs 3 and 4? (Choose two.)

  A. Switch A

  B. Switch B

  C. Switch C

  D. Switch D

  Correct Answer: CD

• Question 634:

  Refer to the exhibit.

  

  The routers in this network are all running EIGRP. What is the most important step to take in order to ensure that this network core will converge quickly should a link failure occur?

  A. make certain EIGRP is running across all links

  B. make certain EIGRP is not running across non-transit links

  C. make certain the maximum number of paths on both of the routers is two

  D. add another link between the two routers with no servers and set the metric on this new link equal to the other four links

  Correct Answer: B

• Question 635:

  Which technique can you use to detect forwarding path failures at a uniform rate, and reconvergence times will be consistent and predictable when your routers are in the same broadcast domain?

  A. Enable BFD on your routers.

  B. Configure your routers with IP-SLA to ping the peer router.

  C. Configure your routers with IP-SLA and track to ping the peer and switch to a default route if the pings fail.

  D. Tune your routing protocol timers.

  Correct Answer: A

• Question 636:

  A company plans to establish a new network using Cisco Catalyst switches for its multicast applications. What is the disadvantage when two multicast applications are using the multicast IP addresses 234.17.4.5 and 234.145.4.5 inside the same network?

  A. Multicast packets from both applications are flooded to all Layer 2 ports in a segment where a multicast receiver is located.

  B. Multicast packets from both applications are flooded to ports where one multicast receiver from one application is located.

  C. Only one multicast stream is received at the port where the receivers from both applications are located.

  D. Both multicast senders will always receive the multicast packets from the other multicast application.

  E. The routers doing PIM-SM cannot distinguish between the two multicast applications.

  Correct Answer: B

• Question 637:

  Among the design criteria for a network is the requirement that bandwidth capacity be managed proactively.

  Which two techniques would most effectively support the proactive management of network bandwidth capacity? (Choose two.)

  A. analyze network bandwidth utilization to establish a baseline

  B. implement QoS to increase available bandwidth and overall throughput

  C. implement utilization measurement and tracking measures in the network

  D. configure SNMP MIB collectors to trigger at utilization thresholds

  Correct Answer: AC

• Question 638:

  B. RA Guard

  C. IKEv2

  D. IPsec

  E. DMVPNv6

  Correct Answer: AB

• Question 639:

  You are asked to design a large campus network that will be using multicast for data transport. Which feature should be enabled at the Layer 2 access edge for host-only ports?

  A. PortFast

  B. BPDU guard

  C. PIM-SM

  D. PIM query interval

  Correct Answer: A

• Question 640:

  When creating a network design that routes an IGP over L2VPNs, with which device does the remote CE router form an IGP adjacency?

  A. the hub site PE router

  B. the hub site CE router

  C. the directly connected PE router

  D. The IGP will not establish adjacency over the MPLS network.

  Correct Answer: B
