Question 2

Which of the following statements regarding the MED attribute are true? (Select 3 answers)

  • A. Based on BGP route selection rules, the MED has precedence over the AS_Path, Preferred-Value, Local-Preference, and Origin attributes.
  • B. The MED of a BGP route is 100 by default.
  • C. Generally, BGP compares only the MEDs of routes received from the same AS but if the "compare- different-as-med" command is configured, BGP can compare the MEDs of the routes received from multiple ASs.
  • D. the default MED value 0 on a BGP indicates that the route is not specified. If the bestroute med- none-as-maximum command is configured, the maximum MED value that can be set is 4294967295.
Answer:

A,C,D

Which of the following statements regarding multicast MAC addresses are true (Select 3 answers)

  • A. The high-order 24 bits of a multicast MAC address are 0x01005e while the low-order 23 bits of a multicast MAC address are the low-order 23 bits of a multicast IP address.
  • B. One multicast MAC address can map 32 different IP multicast addresses.
  • C. Multicast MAC addresses are used in the link layer to identify receivers that are in the same multicast group.
  • D. One multicast MAC address can map only one IP multicast address.
Answer:

A,B,C

Answer:

B

Question 6

Assume that the following commands are run to configure BGP
timer keepalive 30 hold 90
peer 1.1.1.2 timer keepalive 10 hold 30
Which statements regarding the configuration are true? (Select 2 answers)

  • A. A global configuration is preferred. Therefore, the timer values for peer 1.1.1.2 are "keepalive 30 hold 90."
  • B. A peer configuration is preferred. Therefore, the timer values for peer 1.1.1.2 are "keepalive 10 hold 30."
  • C. The smaller value between the global and peer timer values is chosen. Therefore, the timer values for peer 1.1.1.2 are "keepalive 10 hold 30".
  • D. The default configuration is "timer keepalive 60 hold 180." Therefore, peer 1.1.1.2 can detect connection faults faster than the default configuration.
Answer:

B,D

  • B. LS Request packets are sent only after an adjacency is established.

  • D. LS Update packets are sent only after an adjacency is established.

A,B,C

Question 8

RTA is a source's DR and RTB is an RP. A multicast source sends multicast data to RTA but RTB cannot
find any information about the multicast source (registered by using the PIM Register message).
Why? (Select 3 answers)

  • A. RTB has no unicast routes to RTA,
  • B. RTA fails to learn RP information.
  • C. RTA has no unicast routes to RTB.
  • D. The RPlearned by RTA is not RTB.
Answer:

B,C,D

Question 9

Which statement about OSPF is false?

  • A. The router with a higher Router Priority has a higher DR election priority.
  • B. When two routers have the same Router Priority, the one with a larger value for Router ID has a higher DR election priority.
  • C. If a DR fails, the BDR automatically takes over as the DR and a new BDR is elected.
  • D. If a BDR fails, the DR will not take over as the BDR and waits for the fault recovery to handle the situation. No new BDR will be elected.
Answer:

D

  • A. All BGP routes learned from BGP peers are advertised to other BGP peers,
  • B. Only the routes learned from an IGP are advertised to other BGP peers.
  • C. By default, the routes learned from IBGP peers are not advertised to other IBGP peers,
  • D. Only the optimal routes are advertised to other BGP peers.
