Nokia IS-IS Routing Protocol Sample Questions:
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?
- A. The neighbors are identified using their interface MAC addresses on broadcast Hello messages and using their system IDs on point-to-point Hello messages.
- B. 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.
- C. The multicast MAC addresses to which the Hello messages are sent are different on broadcast interfaces and on point-to-point interfaces.
- D. Broadcast Hello messages identify the elected designed IS (DIS) and point-to-point Hello messages do not.
Correct Answer: A 🗳️
When using IS-IS in native mode for routing in a dual-stack IPv4/IPv6 environment, which of the following statements is FALSE?
- A. It may lead to traffic black-holing if not properly designed.
- B. The same topology information is used to calculate the shortest path tree for both IPv4 and IPv6.
- C. In a multi-area environment, the SPF algorithm needs to be run four times on each L1/L2 router.
- D. All links are assumed to be IPv4- and IPv6-capable.
Correct Answer: C 🗳️

All routers in the diagram are running a link-state routing protocol. Before the link failure, all routers have operational adjacencies with each other and there is a BFD session between routers R1 and R3. After the link failure, which of the following affects the routing protocol's convergence time?
- A. The value of the BFD transmit interval, receive interval and multiplier settings on routers R1 and R3.
- B. The time taken by the switches to detect that the physical ports are down.
- C. The value of the Ethernet hello timers on the switches.
- D. The value of the routing protocol hello timers on routers R1 and R3.

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?
- A. Router R1 drops the echo request because address 10.10.10.3 does not belong to an adjacent router.
- B. Router R3 drops the echo request because it does not have subnet 10.4.100.0/24 in its routing table.
- C. Router R2 drops the echo request because it does not have subnet 10.4.100.0/24 in its routing table.
- D. The echo request arrives at the server but there is no path for the echo response to return to router R1.
Correct Answer: D 🗳️

On a broadcast interface, an IS-IS router receives an LSP that is newer than the one on its database. Which of the following statements best describes the actions taken by the router as a consequence?
- A. The router updates its database with the LSP and acknowledges it with a PSNP.
- B. The router updated its database with the LSP, acknowledges the LSP with a PSNP, and floods a copy to its neighbors on other interfaces.
- C. The router sends back a copy of the LSP from its database to its neighbor.
- D. The router updates its database with the LSP and floods a copy to its neighbors on other interfaces.
