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



Which of the following statements about SR-TE administrative constraints is FALSE?

  1. A strict hop must be adjacent to the previous hop in the list.
  2. The TE metric for a link is by default the same as the IGP metric.
  3. Shared-Risk-Link Groups are only taken into account when calculating the secondary path.
  4. The head-end router may calculate a path that takes into account max hop count and bandwidth constraints.

Answer(s): C

Explanation:

Shared-Risk-Link Groups(SRLG) is taken into account when calculating both primary and secondary path to avoid routing over the same physical link.



A router participating in SR-TE is advertising a value of Ox11 for the admin-group membership of one of its interfaces.
Which of the following statements is TRUE?

  1. The interface belongs to admin group RED, configured with a value of 17.
  2. The interface belongs to two different admin groups.
  3. The interface belongs to three different admin groups.
  4. The interface belongs to four different admin groups.

Answer(s): B

Explanation:

In SR-TE, the admin-group is represented by a 32-bit value, where each bit represents a different admin-group. The value Ox11 in binary is 000100010001, which has two bits set to 1, indicating that the interface belongs to two different admin groups. The exact admin-groups that the interface belongs to depends on how the admin-groups have been configured on the router.
