Nokia 4A0-112 exam covers a wide range of topics related to the Nokia IS-IS routing protocol, including the protocol's architecture, configuration, and operation. 4A0-112 exam also covers topics such as network design, implementation, and troubleshooting using the Nokia IS-IS routing protocol. By passing the Nokia 4A0-112 exam, candidates can demonstrate their expertise in the Nokia IS-IS routing protocol and improve their career prospects in the networking industry.

Nokia 4A0-112 exam is designed to assess the skills and knowledge of IT professionals in the area of Intermediary System to Intermediate System (IS-IS) routing protocol. Nokia IS-IS Routing Protocol certification exam is a prerequisite for those who intend to earn the Nokia Service Routing Architect (SRA) certification, which is a highly valued credential in the networking industry. The Nokia 4A0-112 Exam covers a wide range of topics, including IS-IS fundamentals, IS-IS routing protocol operations, network topology and design, and advanced IS-IS features.

Nokia IS-IS Routing Protocol Sample Questions (Q16-Q21):

NEW QUESTION # 16
Refer to the exhibit.

A static route has been configured on router R1 to reach the PC at 139.120.121.2.
What might be causing the ping to fail?

  • A. The configured static route needs to be a default route.
  • B. Router R1 needs a static route to router R2.
  • C. The configured next hop does not belong to a subnet adjacent to R1.
  • D. Router R2 needs a static route to the PC.

Answer: C

Explanation:
In the configuration on router R1, the static route is defined with the next-hop IP address of 139.120.121.1.
However, the next-hop IP address 139.120.121.1 does not belong to the same subnet as the directly connected interface on R1, which is 172.31.1.1/30. For the static route to work properly, the next-hop IP address must be reachable via a directly connected interface, meaning it must be within the same subnet.
Therefore, this mismatch in subnet adjacency is likely causing the failure to reach the destination (139.120.121.2).


NEW QUESTION # 17
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 R6 to router R3, and from router R3 to router R6?

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

Answer: B

Explanation:
The metric values between the routers dictate the routing paths, and IS-IS will calculate the shortest path based on these values.
R6 to R3: The path from R6 to R3 will go through R5 and R2, as this route has the least cumulative metric (10 + 10 + 15 = 35).
R3 to R6: The reverse path from R3 to R6 will follow R3 → R2 → R5 → R6 because this route is also the shortest with a total metric of 10 + 10 + 10 = 30.


NEW QUESTION # 18
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 have a default route with router R2 as the next-hop.
  • B. Router R4 will have a default route with router R3 as the next-hop.
  • C. Router R4 will not have a matching entry in its routing table for router R6's system IP address.
  • D. Router R4 will have a route to router R6's system IP address with router R2 as the next-hop.

Answer: D

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 # 19
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-R3-R5-R6-R7). Router R7 to router R1 will follow (R7-R6-R4-R2-R1).
  • B. Router R1 to router R7 will follow (R1-R3-R5-R6-R7). Router R7 to router R1 will follow (R7-R6-R5-R3-R1).
  • C. Router R1 to router R7 will follow (R1-R2-R4-R6-R7). Router R7 to router R1 will follow (R7-R6-R5-R3-R1).
  • D. Router R1 to router R7 will follow (R1-R2-R4-R6-R7). Router R7 to router R1 will follow (R7-R6-R4-R2-R1).

Answer: D

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 # 20
A routing domain is using a single-area link-state routing protocol. Which of the following is NOT information that a router can share with other routers in the domain using protocol-specific messages?

  • A. A copy of the local routing table.
  • B. The local router ID and the router IDs of neighboring routers.
  • C. IP prefixes known by the router because it is running ad additional routing protocol.
  • D. The IP prefixes of subnets directly attached to the router.

Answer: A

Explanation:
In a single-area link-state routing protocol (such as OSPF), routers share specific information about the network topology, not their entire routing table. They exchange link-state advertisements (LSAs) that contain information about their directly connected interfaces and their state, allowing other routers to build a consistent view of the network.
