Nokia Segment Routing Questions 6–10 (page: 3)

Updated On: 9-Feb-2026

Which of the following steps is NOT required when configuring IS-IS to support Segment Routing?

  1. MPLS label range reserved for Segment Routing.
  2. Enable interfaces used for Segment Routing under
  3. The flooding scope of Segment Routing information.
  4. The Segment Routing Global Block range.

Answer(s): B

Explanation:

Enable interfaces used for Segment Routing under: This step is not required, enabling interfaces used for Segment Routing is not necessary as the IS-IS protocol already takes care of the flooding of the routing information.



OSPF type-10 Opaque LSAs can carry different types of advertisements.
What type of advertisement carries a router's local 5RGB information?

  1. Extended Prefix Info
  2. Router Info
  3. Extended Link Info
  4. Traffic Engineering Info

Answer(s): B

Explanation:

This type of advertisement carries a router's local SRGB information, which is used to distribute information about the local SID allocation range



Which of the following is not required to be advertised by a router participating in Segment Routing?

  1. Local Node-SID
  2. Adjacency-SIDs
  3. Support for SR-MPLS for IPv4 or IPv6, or SRv6
  4. SRGB when SRv6 is configured

Answer(s): D

Explanation:

SRGB when SRv6 is configured: This is not required to be advertised, SRGB(Segment Routing Global Block) is only used for SR-MPLS and is not needed when SRv6 is configured. Instead, SRv6 uses the IANA-assigned IPv6 address space.



Which of the following statements about Segment Routing tunnels is FALSE?

  1. A Segment Routing tunnel defined by a Node-SID uses the shortest IGP Path.
  2. A Segment Routing tunnel can be defined by multiple Node-SIDs.
  3. A Segment Routing tunnel can be defined by a combination of Node-SIDs and Adjacency-SIDs.
  4. For a Segment Routing tunnel, an intermediate router will always forward the packet based on the best IGP path.

Answer(s): D

Explanation:

an intermediate router in a Segment Routing tunnel may forward packets based on the specific SIDs defined in the Segment Routing tunnel and not always the best IGP path.



Which of the following is NOT one of the main goals of traffic engineering?

  1. Utilizing redundant links.
  2. Avoiding potential congestion points in the network.
  3. Defining traffic paths based on various constraints.
  4. Using the shortest possible path through the network to the destination.

Answer(s): D
