QUESTION: 13

Which of the following statements about enabling and using traffic engineering for Segment Routing is FALSE?

One interface can belong to an admin group and SRLG group at the same time.
A link attribute has to be assigned to a particular interface under the [/configure router interface] context
Bandwidth availability as a link attribute cannot be configured.
The interfaces used for SR-TE LSPs have to be added to the MPLS context.

Answer(s): C

Explanation:

Bandwidth availability can be configured as a link attribute in SR-TE, it is used to control the amount of traffic that can be sent over a particular link.

QUESTION: 14

Which of the following list of SR-TE attributes has to be advertised among routers?

Administrative groups that each link belongs to, TE metric of links, bandwidth availability of each link, SRLG that each link belongs to.
Administrative groups that each link belongs to, TE metric of links, SRLG that each link belongs to.
Administrative groups that each link belongs to, TE metric of links, bandwidth availability of each link, SRLG that each link belongs to, link status up/down.
Administrative groups that each link belongs to, TE metric of links, SRLG that each link belongs to, link status up/down.

Answer(s): A

Explanation:

In SR-TE, routers need to advertise certain attributes of their links to other routers in the network in order to calculate traffic-engineered paths. These attributes include:
Administrative groups that each link belongs to: This information is used to restrict the use of certain links to specific traffic types or groups.

TE metric of links: This information is used to calculate the cost of using a particular link for a traffic- engineered path.
Bandwidth availability of each link: This information is used to control the amount of traffic that can be sent over a particular link.
SRLG that each link belongs to: This information is used to avoid routing over the same physical link. Link status up/down is not needed to be advertised as it is part of the IGP protocol and is used to check the reachability of a link.

QUESTION: 15

Based upon the exhibit, which of the following statements regarding the configuration is FALSE?

Traffic engineering information will only be advertised for the interfaces that have both MPLS and RSVP enabled.
The Node-SID assigned to this router is the second label in the defined range.
Traffic engineering has been enabled on this router.
Adjacency-SID labels will not be advertised as they have not been defined under the physical interfaces.

Answer(s): A

QUESTION: 16

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?

The TE information will be advertised for all the OSPF links that have MPLS enabled.
The TE information will only be advertised using application-specific sub-TLVs.
The TE information will only be advertised for the OSPF links that have both MPLS and RSVP enabled.
The TE information will only be advertised using extended-link opaque LSAs.

Answer(s): D

Explanation:

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.
