    Diffusing Update Algorithm

  11. Which destination MAC address is used when a multicast EIGRP packet is encapsulated into an Ethernet frame?





  12. What is the purpose of using protocol-dependent modules in EIGRP?

    to describe different routing processes

    to identify different application layer protocols

    to accommodate routing of different network layer protocols*

    to use different transport protocols for different packets

  13. If all router Ethernet interfaces in an EIGRP network are configured with the default EIGRP timers, how long will a router wait by default to receive an EIGRP packet from its neighbor before declaring the neighbor unreachable?

    10 seconds

    15 seconds*

    20 seconds

    30 seconds

    no shutdown

    bandwidth 1500

    copy running-config startup-config

    no bandwidth*

  15. Which two factors does an EIGRP router use to determine that a route to a remote network meets the feasible condition and is therefore loop-free? (Choose two.)

    the feasible distance on the local router*

    the reported distance on a neighbor router*

    the administrative distance on the remote router

    the successor route on a neighbor router

    the feasible successor route on the remote router

  16. Why would a network administrator use a wildcard mask in the network command when configuring a router to use EIGRP?

    to exclude some interfaces from the EIGRP process*

    to send a manual summarization

    to lower the router overhead

    to subnet at the time of the configuration

  17. Refer to the exhibit. R3 has two possible paths to the network. What is the reported distance of the feasible successor route?





  18. Which statement describes a characteristic of the delivery of EIGRP update packets?

    EIGRP sends all update packets via multicast.

    EIGRP sends all update packets via unicast.

    EIGRP uses a reliable delivery protocol to send all update packets.*

    EIGRP uses UDP to send all update packets.

  19. An administrator issues the router eigrp 100 command on a router. What is the number 100 used for?

    as the length of time this router will wait to hear hello packets from a neighbor

    as the number of neighbors supported by this router

    as the autonomous system number*

    as the maximum bandwidth of the fastest interface on the router

  20. Which two EIGRP packet types are sent with unreliable delivery? (Choose two.)
