QUESTION 23

QUESTION 24
Which of the following is NOT an advantage of using a PCE for the computation of TE-constrained LSP paths, as compared to using CSPF locally on the PE router?

The ability to create cross-area TE-constrained LSP paths

The ability to create LSP paths with bandwidth reservation

The ability to create LSPs with primary and secondary paths

The ability to ensure that some LSP paths are disjoint

QUESTION 25

Extended Prefix Info

Router Info

Extended Link Info

Traffic Engineering Info

QUESTION 26
Which of the following statements about Segment Routing is FALSE?

No path signaling is required to establish an SR tunnel.

Intermediate routers do not maintain any tunnel informal

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

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

QUESTION 27
When OSPF is used to support Segment Routing, the first byte of the link-state ID associated with each of the opaque LSAs indicates the type of information being advertised. Which of the following associations between the first-byte value and its meaning is FALSE?

Value 1 – Traffic Engineering

Value 4 – Router Info

Value 7 – SRGB Range

Value 8 – Extended Link Info

QUESTION 28
Which of the following is NOT a valid option to steer traffic into a flex-algo segment-routing tunnel?

Using a flex-algo Node-SID as an explicit hop in the path definition of an SR-TE LSP and enabling the sr-te tunnel type for a VPN service.

Specifying the flex-algo instance ID as an additional TE constraint for an SR-TE LSP and enabling the sr-te tunnel type for a VPN service.

Configuring and applying a VRF import policy to a VPRN service and enabling the sr-is-is or sr-ospf tunnel type for the service, depending on the underlying routing protocol.

Configuring and applying a VSI import policy to an EVPN service and enabling the sr-is-is or sr-ospf tunnel type for the service, depending on the underlying routing protocol.

QUESTION 29
Loopfree-alternate has been enabled on a router for its link-state routing protocol. For which types of segments will the router attempt to find a backup path, so that they become protected by fast re-route?

Only segments defined by a Node-SID.

Segments defined by a Node-SID and segments defined by an Adjacency-SID.

No segments, unless segment-routing fast-reroute is also explicitly enabled.

QUESTION 30
