1. When multiple routing protocols offer a route for the same prefix, what part of the router is in charge of deciding which route to make active?

The equal cost multipath configuration

The forwarding information base (FIB)

2. What is the replacement for ARP in IPv6?

3. When using IS-IS in native mode for routing in a dual-stack IPv4/IPv6 environment, which of the following statements is FALSE?

All links are assumed to be IPv4- and IPv6-capable.

The same topology information is used to calculate the shortest path tree for both IPv4 and IPv6.

In a multi-area environment, the SPF algorithm needs to be run four times on each L1/L2 router.

It may lead to traffic black-holing if not properly designed.

4. Which of the following statements about the IP forwarding process on a router is TRUE?

It uses the routing table to find a match for the source IP address.

It uses the routing table to find a match for the destination IP address.

It uses the ARP table to find a match for the source MAC address.

It uses the ARP table to find a match for the destination MAC address.

5. Refer to the exhibit.





Routers R1, R2, R3, and R4 are running IS-IS.

Assuming all interfaces are added to IS-IS as point-to-point and no commands are issued at the interface level to restrict adjacencies, which of the following statements is TRUE?

Routers R1 and R2 are L2 routers. Routers R3 and R4 are L1 routers.

Routers R1 and R2 are L2 routers. Routers R3 and R4 are L1/L2 routers.

Routers R1 and R2 are L1/L2 routers. Routers R3 and R4 are L1 routers.

All four routers are L1/L2.

6. An IS-IS router receives a CSNP that references an older LSP than the one in its local database.

What action is taken?

The router sends a copy of the referenced LSP from its database to its neighbor.

The router sends a CSNP to its neighbor describing the newer LSPs in its database.

The router updates its database with the new sequence number and floods a copy of the LSP to its other neighbors.

The router sends a PSNP to its neighbor to request a copy of the LS

7. Refer to the exhibit.





Routers R1 through R4 in the diagram have established IS-IS adjacencies. Router R1 is L1/L2 and is the DIS of its two broadcast interfaces.

How many LSPs will it generate?

8. Which of the following is a valid alternative representation of the IPv6 address 2001:0da8:0000:0000:0024:0000:4ab9:0300?

2001:0da8::0024:0000:4ab9:03

2001:da8::0:24::4ab9:300

9. Refer to the exhibit.





All routers in the diagram are running an interior gateway protocol (IGP) and have been configured with an ECMP value of 4. Router R5 advertises the prefix 192.168.3.0/24 using the IGP.

Assuming all links have the same cost, how many entries for prefix 192.168.3.0/24 will be in router R3’s routing table?

10. Refer to the exhibit.





Routers R1 through R4 are running an IGP in such a way that they have each other’s system IP addresses in their routing tables. A static route is configured on router R1 so that it can reach subnetwork 10.4.100.0/24. The network administrator decides to use an indirect static route, as shown in the diagram. However, pinging the server from router R1 fails.

What may be the problem in this case?

Router R1 drops the echo request because address 10.10.10.3 does not belong to an adjacent router.

Router R2 drops the echo request because it does not have subnet 10.4.100.0/24 in its routing table.

Router R3 drops the echo request because it does not have subnet 10.4.100.0/24 in its routing table.

The echo request arrives at the server but there is no path for the echo response to return to router R1.

11. When a router performs the SPF calculation, which router is used as the root of the shortest path tree?

The router with the fewest links.

The router with the lowest router I

The router's closest neighbor.

The router doing the calculation.

12. There are several differences between IS-IS Hello packets used on broadcast interfaces and on point-to-point interfaces.

Which of the following statements is FALSE?

On broadcast interfaces there are different Hello packet types for level-1 and level-2 adjacencies, whereas on point-to-point interfaces there is a single Hello packet type.

The multicast MAC addresses to which the Hello messages are sent are different on broadcast interfaces and on point-to-point interfaces.

The neighbors are identified using their interface MAC addresses on broadcast Hello messages and using their system IDs on point-to-point Hello messages.

Broadcast Hello messages identify the elected designed IS (DIS) and point-to-point Hello messages do not.
