Nokia IS-IS Routing Protocol Sample Questions (Q41-Q46):

NEW QUESTION # 41
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?

A. The routing table manager (RTM)
B. The forwarding information base (FIB)
C. The equal cost multipath configuration
D. The routing information base (RIB)

Answer: A

Explanation:
The routing table manager (RTM) is responsible for selecting the best route when multiple routing protocols provide a route for the same destination prefix. It makes the decision on which route to add to the routing table based on the administrative distance, metric, and other criteria.

NEW QUESTION # 42
Refer to the exhibit.

In the diagram, all routers are using IS-IS as their routing protocol. The number next to each link is its metric value.
What path will traffic follow from router R1 to router R7, and from router R7 to router R1?

A. Router R1 to router R7 will follow (R1-R2-R4-R6-R7). Router R7 to router R1 will follow (R7-R6-R4-R2-R1).
B. Router R1 to router R7 will follow (R1-R2-R4-R6-R7). Router R7 to router R1 will follow (R7-R6-R5-R3-R1).
C. Router R1 to router R7 will follow (R1-R3-R5-R6-R7). Router R7 to router R1 will follow (R7-R6-R4-R2-R1).
D. Router R1 to router R7 will follow (R1-R3-R5-R6-R7). Router R7 to router R1 will follow (R7-R6-R5-R3-R1).

Answer: A

Explanation:
From R1 to R7: The path will be R1 → R2 → R4 → R6 → R7 because this path has the least cumulative metric of 10 + 10 + 10 + 10 = 40.
From R7 to R1: The reverse path will follow R7 → R6 → R4 → R2 → R1 because it is the shortest return path with the same metrics.

NEW QUESTION # 43
Refer to the exhibit.

Examine the physical topology of the IS-IS network, the metrics of the links and the levels of the routers. All routers have their system interfaces included in IS-IS. Which of the following statements describes the route-table entry that router R4 will use to reach the system IP address of router R6?

A. Router R4 will not have a matching entry in its routing table for router R6's system IP address.
B. Router R4 will have a default route with router R2 as the next-hop.
C. Router R4 will have a route to router R6's system IP address with router R2 as the next-hop.
D. Router R4 will have a default route with router R3 as the next-hop.

Answer: C

Explanation:
Router R4 is in Area 49.0001 and R6 is in Area 49.0002. Both routers are Level 2 (L2), meaning that they can communicate across areas using Level 2 IS-IS routing.
Since R2 is the L1/L2 router that connects both Area 49.0001 and Area 49.0002, it will be the next-hop for router R4 to reach R6's system IP address.
The IS-IS protocol will ensure that R4 will have a route to R6's system IP address via R2 as the next-hop.

NEW QUESTION # 44
Which of the following is NOT a function of the control plane a router?

A. To exchange signaling messages with other routers.
B. To determine the best way to forward packets.
C. To establish routing paths to deliver packets from source to destination and to reestablish them in case of failure.
D. To utilize the forwarding tables to forward data packets towards their destination.

Answer: D

Explanation:
The data plane (or forwarding plane) is responsible for actually forwarding the data packets. It uses the information stored in the forwarding table to determine how to move packets from one interface to another toward their destination.

NEW QUESTION # 45
A series of actions are triggered on a router as a result of enabling both loopfree-alternate for a link-state routing protocol and ip-fast-reroute. Which of the following is NOT one of those actions?

A. Enabling the router to locally repair the active path to an IP prefix in case of failure.
B. Calculating the shortest-path next hop for each known IP prefix.
C. Installing two entries in the FIB for IP prefixes, one active and one in standby mode.
D. Calculating a backup next hop for each known IP prefix, if it exists, that would not create a routing loop if used without informing other routers.

Answer: B
