Based on the configuration shown for routers R1 and R10, what valid flex-algo definitions exist in the network?

A.

No valid flex-algo definitions, because of the conflicting parameters.

B.

One valid flex-algo definition, using delay as the link metric and including green links.

C.

One valid flex-algo definition, using te-metric as the link metric and including blue links.

D.

Two valid flex-algo definitions, one uses te-metric as the link metric and includes blue links and the other uses delay as the link met includes green links.

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

A.

Traffic engineering information will only be advertised for the interfaces that have both MPLS and RSVP enabled.

B.

The Node-SID assigned to this router is the second label in the defined range.

C.

Traffic engineering has been enabled on this router.

D.

Adjacency-SID labels will not be advertised as they have not been defined under the physical interfaces.

Which of the following statements about Segment Routing is FALSE?

A.

No path signaling is required to establish an SR tunnel.

B.

Intermediate routers do not maintain any tunnel informal

C.

A link-state IGP is required to distribute SID information.

D.

For TE-constrained tunnels, each data packet typically carries a single MPLS label to specify the tunnel path.

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?

A.

The TE information will be advertised for all the OSPF links that have MPLS enabled.

B.

The TE information will only be advertised using application-specific sub-TLVs.

C.

The TE information will only be advertised for the OSPF links that have both MPLS and RSVP enabled.

D.

The TE information will only be advertised using extended-link opaque LSAs.

Examine the exhibit. Based upon the configuration, which routers will the LSP go through?

A.

R1, R3, R2, R5, R4 and R6

B.

R1, R2, R5 and R6

C.

R1, R3, R4 and R6

D.

R1, R2, R4 and R6

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

A.

Label stack size of the encapsulated data packets

B.

List of traffic-engineering constraint types available to choose from

C.

Ability to associate one primary and up to two secondary paths to the same LSP

D.

Flexibility of configuring each LSP with its own set of traffic-engineering constraints

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

A.

Local Node-SID

B.

Adjacency-SIDs

C.

Support for SR-MPLS for IPv4 or IPv6, or SRv6

SRGB when SRv6 is configured

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

A.

Extended Prefix Info

B.

Router Info

C.

Extended Link Info

D.

Traffic Engineering Info

To create a flex-algo instance in a network, which of the following configuration steps is mandatory?

A.

Configuring the proper values for the shared-risk link groups (SRLGs) that will define the flex-algo topology.

B.

Configuring at least one router in the network to create and advertise the flex-algo definition.

C.

Specifying whether the LSP paths will be computed locally or by an external path computation element (PCE).

D.

Configuring LSPs between every pair of PE routers.

Based on the exhibit, which of the following is a viable option for the Path Computation Element (PCE) to obtain all the necessary topology and traffic-engineering information from the network, so that it can calculate LSP paths on behalf of the PE routers?

A.

Establishing an IGP adjacency with router R2

B.

Establishing IGP adjacencies with routers R1 and R2

C.

Establishing a BGP session using the BGP-LS address family with router R3

D.

Establishing BGP sessions using the BGP-LS address family with routers R3 and R4
