Quiz 2025 Updated Nokia 4A0-112: Nokia IS-IS Routing Protocol Unlimited Exam Practice

The Nokia IS-IS Routing Protocol (4A0-112) examination is necessary for career advancement, therefore, doing your best to prepare for the Nokia IS-IS Routing Protocol (4A0-112) certification exam is essential. To succeed on the Nokia IS-IS Routing Protocol (4A0-112) exam, you require a specific Nokia IS-IS Routing Protocol (4A0-112) exam environment to practice. But before settling on any one method, you make sure that it addresses their specific concerns about the 4A0-112 Exam, such as whether or not the platform they are joining will aid them in passing the Nokia IS-IS Routing Protocol (4A0-112) exam on the first try, whether or not it will be worthwhile, and will it provide the necessary 4A0-112 Questions.

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

NEW QUESTION # 41
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?

  • A. Routers R1 and R2 are L1/L2 routers. Routers R3 and R4 are L1 routers.
  • B. Routers R1 and R2 are L2 routers. Routers R3 and R4 are L1/L2 routers.
  • C. Routers R1 and R2 are L2 routers. Routers R3 and R4 are L1 routers.
  • D. All four routers are L1/L2.

Answer: A

Explanation:
From the output, we can see that the usage column indicates whether a router is operating as an L1 or L2 router:
The L1/L2 designations refer to whether the routers participate in both Level 1 and Level 2 of IS-IS:
In this case, R1 and R2 are L2 routers, and R3 and R4 are L1 routers.


NEW QUESTION # 42
Which of the following statements about router interfaces on a Nokia 7750 SR is FALSE?

  • A. They can be used in pairs on the same subnet for redundancy.
  • B. The system interface exists by default.
  • C. They can be assigned IPv4 and/or IPv6 addresses.
  • D. They can be logical or physical.

Answer: A

Explanation:
Typically, interfaces on a Nokia 7750 SR router are not configured in pairs on the same subnet for redundancy. Instead, redundancy is achieved through mechanisms like Virtual Router Redundancy Protocol (VRRP) or other high availability protocols, not by simply using interfaces in pairs on the same subnet.


NEW QUESTION # 43
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. IP prefixes known by the router because it is running ad additional routing protocol.
  • B. The local router ID and the router IDs of neighboring routers.
  • C. A copy of the local routing table.
  • D. The IP prefixes of subnets directly attached to the router.

Answer: C

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.


NEW QUESTION # 44
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?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: D

Explanation:
In this scenario, the routers are configured with an Equal-Cost Multi-Path (ECMP) value of 4, meaning they can utilize up to 4 equal-cost paths to reach a destination. Since Router R5 is advertising the 192.168.3.0/24 prefix and all links have the same cost, router R3 will receive multiple routes to reach this destination.
Given that all the routers (R1, R2, R3, R4, and R5) are connected in a way that can support multiple equal-cost paths, and assuming ECMP is set to 4, the routing table on Router R3 will have up to 4 entries for the prefix 192.168.3.0/24.
Thus, Router R3's routing table will contain 4 entries for the prefix 192.168.3.0/24.


NEW QUESTION # 45
Two IS-IS neighboring routers are trying to establish an adjacency, but the interface has been configured as broadcast on one of them and as point-to-point on the other. Why is the adjacency not established?

  • A. The routers do not receive each other's Hello messages because they listen for messages transmitted to different multicast IP addresses.
  • B. The routers discard the received Hello messages because they are not the expected type: LAN Hello vs point-to-point Hello.
  • C. The routers do not agree on the result of the DIS election.
  • D. The routers do not receive each other's Hello messages because they listen for messages transmitted to different multicast MAC addresses.

Answer: B

Explanation:
IS-IS routers use different types of Hello messages depending on whether the interface is configured as a broadcast (LAN) or point-to-point (P2P) link.
On a broadcast network (e.g., Ethernet), IS-IS routers use LAN Hello packets to establish adjacencies.
On a point-to-point link, IS-IS uses point-to-point Hello packets.
If one router is configured for a broadcast interface and the other for point-to-point, they will exchange incompatible Hello packets, and as a result, neither router will accept the other's Hello messages, preventing the adjacency from being established.
