Question 1

Based on the exhibit, which of the following statements about fast re-route for flex-algo instance 129 is TRUE?

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

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

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

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

Answer : C

Question 2

Which of the following statements about the Path Computation Element (PCE) is FALSE?

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

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

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

DA stateful PCE can allow LSPs to reserve bandwidth.

Answer : D

Stateful PCE can monitor the existing LSPs and trigger necessary repairs and re-optimizations, but it does not have the capability to reserve bandwidth.

Question 3

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

AR1, R3, R2, R5, R4 and R6

BR1, R2, R5 and R6

CR1, R3, R4 and R6

DR1, R2, R4 and R6

Answer : C

Question 4

Examine the exhibit.

An LSP is being configured to start at R1 and end at R6 using local CSPF. The LSP has the following constraints. Include admin-group GREEN, use the TE metric and hop-limit 3. What routers will be included in the LSP path?

AR1, R2, R4, R6

BR1, R5, R6

CR1, R3, R5, R6

DR1, R6

Answer : C

Question 5

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?

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

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

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

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

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 6

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

AMPLS label range reserved for Segment Routing.

BEnable interfaces used for Segment Routing under

CThe flooding scope of Segment Routing information.

DThe Segment Routing Global Block range.

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 7

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?

AValue 1 - Traffic Engineering

BValue 4 - Router Info

CValue 7 - SRGB Range

DValue 8 - Extended Link Info

Answer : D

Value 8 - Extended Link Info: This statement is not true, value 8 is not used to indicate Extended Link Info. It is used for different types of information, such as Link-Local/Remote Identifiers (LLS/RLS) Identifiers and Node SID/Adj-SID.
