Testing yourself is an effective way to enhance your knowledge and become familiar with the 4A0-112 exam format. Rather than viewing the 4A0-112 test as a potentially intimidating event, Pass4Leader Nokia IS-IS Routing Protocol (4A0-112) desktop and web-based practice exams help candidates assess and improve their knowledge. If your 4A0-112 Practice Exams (desktop and web-based) results aren't ideal, it's better to experience that shock during a mock exam rather than the 4A0-112 actual test.

Passing the Nokia 4A0-112 exam is a significant accomplishment that demonstrates a high level of expertise in the IS-IS routing protocol. Nokia IS-IS Routing Protocol certification is recognized by networking professionals and employers as a valuable credential that signifies a candidate's ability to design, deploy, and manage complex network environments. With the demand for skilled network engineers continuing to grow, obtaining the Nokia 4A0-112 certification can open up new opportunities for career advancement and professional development.

Nokia 4A0-112 certification exam is designed to test the proficiency of individuals in implementing and configuring the Intermediate System to Intermediate System (IS-IS) routing protocol in Nokia networks. 4A0-112 Exam is intended for network professionals who work with Nokia Service Routing Operating System (SROS) and have experience in implementing and troubleshooting IS-IS-based networks.

Nokia 4A0-112 is a certification exam that evaluates the candidate's knowledge and expertise in Nokia's IS-IS routing protocol. 4A0-112 exam is designed to test the candidate's proficiency in implementing and configuring IS-IS protocol in Nokia's Service Routing Architect (SRA) platform. It is an intermediate-level exam that requires a strong foundation in networking concepts and routing protocols.

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

NEW QUESTION # 41
Which of the following is NOT a function of the control plane a router?

  • A. To utilize the forwarding tables to forward data packets towards their destination.
  • 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 exchange signaling messages with other routers.

Answer: A

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 # 42
Refer to the exhibit.

Which of the following statements best describes the IS-IS domain to which the command output corresponds?

  • A. Multi-area IS-IS domain with no broadcast interfaces.
  • B. Multi-area IS-IS domain with broadcast interfaces.
  • C. Single-area IS-IS domain with broadcast interfaces.
  • D. Single-area IS-IS domain with no broadcast interfaces.

Answer: B

Explanation:
The output shows two levels of IS-IS databases: Level 1 (L1) and Level 2 (L2). This indicates that the domain is multi-area, as L1 routers are confined to a single area, while L2 routers can route between different areas. The presence of Level 1/Level 2 (L1/L2) routers also suggests that the domain spans multiple areas.
The LSP (Link-State PDU) entries show L1/L2 ATT attributes, which typically indicate that these routers are capable of routing both within their own area (Level 1) and across areas (Level 2), suggesting a multi-area design.
The IS-IS domain likely includes broadcast interfaces, as indicated by the "ATT" attribute (typically referring to the type of interface) and common IS-IS configuration practices on broadcast networks like Ethernet.


NEW QUESTION # 43
When using IS-IS in native mode for routing in a dual-stack IPv4/IPv6 environment, which of the following statements is FALSE?

  • A. In a multi-area environment, the SPF algorithm needs to be run four times on each L1/L2 router.
  • B. The same topology information is used to calculate the shortest path tree for both IPv4 and IPv6.
  • C. All links are assumed to be IPv4- and IPv6-capable.
  • D. It may lead to traffic black-holing if not properly designed.

Answer: A

Explanation:
In a dual-stack IPv4/IPv6 IS-IS environment, the SPF (Shortest Path First) algorithm is only run once per router for each protocol (IPv4 or IPv6). The topology is shared, but the SPF calculations for IPv4 and IPv6 are separate. This means that the SPF algorithm will run twice (once for IPv4 and once for IPv6) for each L1/L2 router, not four times.


NEW QUESTION # 44
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-R2-R4-R6-R7). Router R7 to router R1 will follow (R7-R6-R4-R2-R1).
  • C. Router R1 to router R7 will follow (R1-R3-R5-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-R5-R3-R1).

Answer: B

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 # 45
Which of the following statements about the IP forwarding process on a router is TRUE?

  • A. It uses the ARP table to find a match for the source MAC address.
  • B. It uses the routing table to find a match for the destination IP address.
  • C. It uses the routing table to find a match for the source IP address.
  • D. It uses the ARP table to find a match for the destination MAC address.

Answer: B

Explanation:
During the IP forwarding process, routers use the routing table to determine the next hop based on the destination IP address. The source IP address is not directly involved in the lookup process for forwarding.
The ARP table is used to map IP addresses to MAC addresses, specifically for resolving the MAC address of the next hop (destination MAC address) for forwarding packets within the local network.
