4. Question NO :3

the ABR. Which change in the configuration of the OSPF area type causes traffic from that area that is destined to the
Internet to be dropped?

Answer: D
5. Question NO :4
Which measure does ISIS use to avoid sending traffic with a wrong MTU configuration?

6. Question NO :5
Refer to the exhibit. Assuming that the peer is configured correctly and the interface is up, how many neighbors will be
seen in the EIGRPv6 neighbor table on this IPv6-only router?
A. one neighbor, which will use a local router-id of 6010. AB8. . /64
B. one neighbor, which will use a local router-id of 6020. AB8. . /64
C. none, because EIGRPv6 only supports authenticated peers
D. none, because of the mismatch of timers

Answer: E

D. . . ffff. /16
E. . . ffff. 0. 0/96
Answer: E
9. Question NO :8
Refer to the exhibit. Which statement is true?
A. R2 is directly connected to the receiver for this group and is the winner of an assert mechanism.
B. R2 is directly connected to the receiver for this group, and it forwards the traffic onto Ethernet3/0, but it is forwarding
duplicate traffic onto Ethernet3/0.
C. R2 has the A flag (Accept flag) set on Ethernet 3/0. This is fine, since the group is in BIDIR PIM mode.
D. R2 is directly connected to the receiver for this group and is the loser of an assert mechanism.
E. The A flag is set until the SPT threshold is reached for this multicast group.
Answer: A
10. Question NO :9
As a best practice, when a router is configured as an EIGRP Stub, which routes should be received from its distribution
neighbor?

B. static routes
C. internal routes only
D. internal and external routes
Answer: A
