Question 5

Which of the following protocols are multicast routing protocol? (Choose three.)

Accepted Answer

A)  DVMRP 
B)  PIM-DM 
C)  OSPF 
D)  PIM-SM

Question 6

Assume that the following commands are run to configure BGP:  Which statements about the configurations are true? (Choose two.)

Accepted Answer

A)  The global configuration is preferred. Therefore, the timer values for peer 1.1.1.2 are "keepalive 30 hold 90." 
B)  The peer configuration is preferred. Therefore, the timer values for peer 1.1.1.2 are "keepalive 10 hold 30." 
C)  The smaller one between the global and peer timer values is used. Therefore, the timer values of peer 1.1.1.2 is "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.

Accepted Answer

A)  The smaller the sequence number, the more recent the LSA.
