Questions # 168:

Which of the following statements regarding IS-IS Hello packets are true? Choose two answers.

Options:

A.

Different types of Hello packets are exchanged on point-to-point networks than on broadcast networks.


B.

L1/L2 Hello packets are exchanged on broadcast links.


C.

Different L1 and L2 Hello packets are exchanged on broadcast links.


D.

By default, Hello packets are sent every 5 seconds, and the timeout to declare a neighbor down is 15 seconds.


Questions # 169:

Options:

A.

B.

When an area needs to traverse another area to reach area 0.

Question # 170

What triggers convergence of the routing protocol when the link between switch 1 and switch 2 goes down?

Options:

A.

Convergence is triggered when the adjacency between routers R1 and R2 drops as a result of Hello timeouts. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.


B.

Convergence is triggered when the physical interfaces between routers R1 and R2 go down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.


C.

Convergence will not be triggered because switches cannot run routing protocols between them.


D.

Convergence is triggered when the switches notify the routers about the link state information. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged


E.

Convergence is triggered when an LSA is sent from router R1 to router R2 to indicate that the link is down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.


Questions # 171:

What is another term to describe the default route for a client?

Options:

A.

Black hole


B.

Default gateway


C.

Gateway path


D.

Proxy ARP

Questions # 175:

Which of the following describes the method used to resolve an IPv6 address to a MAC address?

Options:

A.

IPv6 uses the Address Resolution Protocol to resolve the address to a MAC address.


B.

A Neighbor Discovery message is sent to the broadcast MAC address. The host with the IPv6 address responds with a Neighbor Advertisement message.


C.

A Neighbor Discovery message is sent to the solicited-node multicast address. The host with the IPv6 address responds with a Neighbor Advertisement message.


D.

A Neighbor Discovery message is sent to the anycast address for the LAN. The host with the IPv6 address responds with a Neighbor Advertisement message.


E.

IPv6 addresses do not need to be resolved to a MAC address.
