NO.19 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.

Only segments defined by an Adjacency-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.

NO.20 The exhibit shows the fast re-route configuration on router R1, in which both R-LFA and TI-LFA have been enabled. Assume that there are multiple potential backup paths for a given prefix. Which of the following options will router R1 use?

A standard LFA path that would not coincide with the path after IGP re-convergence.

An R-LFA path that would not coincide with the path after IGP re-convergence.

A D-LFA path that would not coincide with the path after IGP re-convergence.

A D-LFA path that would coincide with the path after IGP re-convergence.

NO.21 Which of the following statements about segment routing fast re-route is FALSE?

Fast re-route is a temporary fix that becomes active for a short period of time after a local network failure.

Fast re-route typically protects the active segment of a tunnel, but under certain conditions it can protect an end-to-end multi-segment tunnel instead.

On a Nokia 7750 SR, R-LFA and TI-LFA can be enabled independently of each other.

The parameter “max-sr-frr-labels” limits the number of labels that R-LFA can add to the data packet encapsulation.

NO.22 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.

NO.23 Which of the following statements about the Path Computation Element (PCE) is FALSE?

The PCE can obtain topology and traffic-engineering information from the network using either a link-state IGP or BGP-LS.

A stateful PCE proactively monitors all the existing LSPs and triggers the necessary repairs and re-optimizations.

A stateless PCE can calculate cross-area traffic-engineering-constrained LSP paths.

A stateful PCE can allow LSPs to reserve bandwidth.

NO.24 Based on the exhibit, which of the following statements about fast re-route for flex-algo instance 129 is TRUE?

Only standard LFA is enabled on router R1; fast re-route is not enabled on router R2.

Only standard LFA is enabled on both routers R1 and R2.

Standard LFA and remote-LFA are enabled on router R1; fast re-route is not enabled on router R2.

Standard LFA and remote-LFA are enabled on router R1; standard LFA and TT-LFA are enabled on router R2.

NO.25 Which of the following statements about a Segment Routing SID is FALSE?

A local Node-SID can be configured directly as an MPLS label.

A router advertises its local Node-SID as a local SRGB and an index only if it is configured as an index.

All routers do NOT need to have the same SRGB range configured.

A local Node-SID can be configured as an index.

NO.26 Based on the exhibit, and given that the system IP address of router RIO is 10.10.10.10, which of the following statements is FALSE?

Router Rl participates in at least two flex-algo instances.

Router RIO participates in flex-algo instance 130.

The Node-SID assigned to router RIO for flex-algo instance 129 is 524338.

The underlying routing protocol being used in the network for segment routing is IS-IS.

NO.27 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.

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.

NO.28 The exhibit highlights in blue the primary path of a segment going from router S to router D.
The exhibit also shows a backup path. The protected link fails and fast re-route is triggered on router S. If the backup path has been calculated using standard LFA, how many SIDs are included in the label stack of the data packet forwarded to router R1?

NO.29 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?
