Which design consideration should be observed when EIGRP is configured on Data Center switches?

  1. Perform manual summarization on all Layer 3 interfaces to minimize the size of the routing table.
  2. Prevent unnecessary EIGRP neighborships from forming across switch virtual interfaces.
  3. Lower EIGRP hello and hold timers to their minimum settings to ensure rapid route reconvergence.
  4. Configure multiple EIGRP autonomous systems to segment Data Center services and applications.

Answer(s): B



Which design consideration must be made when using IPv6 overlay tunnels?

  1. Overlay tunnels that connect isolated IPv6 networks are considered a final IPv6 network architecture.
  2. Overlay tunnels should only be considered as a transition technique toward a permanent solution.
  3. Overlay tunnels should be configured only between border devices and require only the IPv6 protocol stack.
  4. Overlay tunneling encapsulates IPv4 packets in IPv6 packets for delivery across an IPv6 infrastructure.

Answer(s): B

A network solution is being designed for a company that connects to multiple Internet service providers. Which Cisco proprietary BGP path attribute will influence outbound traffic flow?

  1. Local Preference
  2. MED
  3. Weight
  4. AS Path
  5. Community

Answer(s): C





Refer to the exhibit. EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the WAN links to R4. When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?

  1. R1 has no route to R2 and drops the traffic
  2. R1 load-balances across the paths through R3 and R4 to reach R2
  3. R1 forwards the traffic to R3, but R3 drops the traffic
  4. R1 forwards the traffic to R3 in order to reach R2

Answer(s): A
