2. Which of the following situatbns will occur when the command multicast bad balance” is configured? (Select 3 answers)

   • If there exists no unicast equal-cost routes, multicast load balancing fails.
   • If group address-based load splitting is employed, balanced distribution of entries over equal-cost routes cannot be ensured due to hash function limitations.
   • Balanced distribution of entries over equal-cost routes can be ensured as long as multicast load balancing is performed.
   • During multicast load splitting, traffic may not be balanced among equal-cost routes because multicast load balancing is based on multicast entries not multicast data packets.

3. Which statement regarding BGP is false?

   • BGP runs over TCP.
   • BGP is an enhanced distance-vector routing protocol.
   • BGP uses port number 189.
   • BGP is an inter-AS routing protocol.

4. A router can be configured to run only one BGP routing process.

   • TRUE 
   • FALSE

   • TRUE
   • FALSE

   • TRUE 
   • FALSE

    • P2P
    • P2MP
    • Broadcast
    • Virtual link

12. Which of the following statements regarding the IP address 224.0.0.1 are correct? (Select 2 answers)

    • It is a multicast IP address 
    • It is a private IP address
    • It represents all the hosts and routers 
    • It represents all the routers

13. Which of the following IP addresses can be used on a public network? (Select 2 answers)

    • 172.30.0.1/16
    • 127.254.11.15/16

    • TRUE
    • FALSE

15. Based on BGP route selection rules, the route with the lowest multi-exit discriminator (MED) is preferred.

    • TRUE
    • FALSE

16. What is the default LOCAL_PREF and PREFERRED-VALUE assigned to routes in a VRP system?

    • 0,32768

    • 255,100
    • 32768,0

17. How does an IGMP router maintain group memberships on a network? (Select 2 answers)

    • The router maintains a timer for each group membership which it refreshes for hosts that send report messages and deletes the group membership of hosts that do not.
    • The router periodically sends Query messages. After a receiver host receives the Query message, the receiver host sends a Report message.
    • A receiver host periodically sends a Report message.
    • The router deletes a group membership only when it receives a Leave message for this group.
