Question No. 1

Which of the following statements about Multi-Protocol Label Switching networks is FALSE?

Show Answer Hide Answer
Correct Answer: D

The data is transparently carried from end to end: This statement is not true, MPLS does not provide data transparency, which means that the data is not carried unmodified from end to end. MPLS uses labels to forward data, so the original IP packets are encapsulated in new MPLS packets, and the original IP headers are not visible at the egress LSR.


Question No. 2

OSPF is being used for segment routing with traffic-engineering (SR-TE). The traffic-engineering option has been set to "sr-te false". Which of the following statements is TRUE?

Show Answer Hide Answer
Correct Answer: D

When using Segment Routing with Traffic Engineering (SR-TE) in OSPF, the TE information is advertised using extended-link opaque LSAs. The option 'sr-te false' indicates that OSPF will not advertise the TE information in the OSPF database, thus the routers will not be aware of the TE information.


Question No. 3

Which of the following statements about Segment Routing is FALSE?

Show Answer Hide Answer
Correct Answer: B

Intermediate routers do not maintain any tunnel informal: this statement is false, Intermediate routers do maintain tunnel information, such as the Forwarding Information Base (FIB) to forward the packets according to the path specified in the packets.


Question No. 4

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

Show Answer Hide Answer
Correct Answer: B

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.


Question No. 5

In which of the following aspects does the configuration of flex-algo LSPs have an advantage over the configuration of SR-TE LSPs?

Show Answer Hide Answer
Correct Answer: D

Flex-Algo LSPs are a type of LSP that allows for greater flexibility in configuring traffic engineering constraints. This is because flex-algo LSPs can be configured with a unique set of traffic engineering constraints for each LSP, whereas SR-TE LSPs use a predefined set of traffic engineering constraints that applies to all LSPs.

Label stack size of the encapsulated data packets, List of traffic-engineering constraint types available to choose from, and Ability to associate one primary and up to two secondary paths to the same LSP are not the advantages of flex-algo LSPs over SR-TE LSPs.
