Question 1

Which of the following statements regarding LSP path configuration are true? (Choose three)

A :

The path must include at least one hop.

B :

The path may be used multiple times in a single LSP.

C : The path may comprise loose hop entries only.

D : The path must define the LSP's tail end.

E :

The path may be used for multiple LSPs.

Answer: A,D

Question 2

Which of the following regarding label population is TRUE?

A : Selected labels from the FIB are populated to the LFIB.

B : Selected labels from the RIB are populated to the FIB.

C : Selected labels from the LIB are populated to the FIB.

D : Selected labels from the LIB are populated to the LFIB.

Answer: D

Question 3

Click on the exhibit.

Initially, all links along the path R1-R2-R4-R6 have 400Mbps unreserved bandwidth and all links along the path

R1-R3-R5-R6 have 800Mbps unreserved bandwidth. Shared Explicit reservation style is used and MakeBefore-Break is enabled. Both fully loose LSPs have been signaled as shown. Later, the configured bandwidth

for LSP-1 is changed to 400Mbps. Which of the following is TRUE?

A : After a new path for LSP-1 is established on R1-R3-R5-R6, the old path is torn down.

B : After the old path for LSP-1 is torn down, the new path is established on R1-R3-R5-R6.

C : LSP-1 will stay on R1-R2-R4-R6 because there is enough bandwidth on the existing path.

D : LSP-1 will be torn down because CSPF fails to find a new path.

Answer: C

Question 4

How does MPLS-TE overcome the issue of IP hyper-aggregation?

A : By enabling the creation of LSPs across alternate links to balance the network traffic.

B : By eliminating the requirement for core IP routing

C : By not allowing more than one LSP to use a particular path.

D :

By defining multiple LSPs across a network and implementing an IGP load balancing algorithm across

them.

Answer: A

Question 5

Which of the following about Alcatel-Lucent 7750 SR command "oam Isp-trace prefix" is FALSE?

A : The router performs a unidirectional LSP test.

B : The router collects hop information along the tunnel's path.

C : The router uses MPLS Echo Request packets that are IP-routed,

D : The MPLS TTL values are incremented at each request.
