Then, LSP 2 is signaled with setup and hold priority of 5. Both LSPs go from R1 to R5. Which of the following is TRUE?

ALSP 1 will follow R1-R3-R4-R5. LSP 2 will follow R1-R2-R5.

BLSP1 will follow R1-R2-R5. LSP 2 will follow R1-R3-R4-R5.

CBoth LSP 1 and LSP 2 will follow R1-R2-R5.

DBoth LSP 1 and LSP 2 will follow R1-R3-R4-R5.

Answer : C

Question 4

Click on the exhibit.

All links have 1Gbps unreserved bandwidth initially and Shared Explicit reservation style is used. After the LSP's primary and standby secondary paths are signaled, how much unreserved bandwidth is left on the links?

AR1-R2 will have 300Mbps left and R2-R4 will have 400Mbps left.

BR1-R2 will have 400Mbps left and R2-R4 will have 400Mbps left.

CR1-R2 will have 600Mbps left and R2-R4 will have 600Mbps left.

DR1-R2 will have 300Mbps left and R2-R4 will have 600Mbps left.

Answer : C

Question 5

Click on the exhibit.

The link between routers R4 and R6 are configured with an admin group "red". What happens when the LSP is first signaled?

AThe LSP will go through the path R1-R2-R4-R6.

BThe LSP will go through the path R1-R3-R5-R6.

CThe LSP is down because router R1 detects that no path can meet its constraints.

DThe LSP is down because router R4 detects that no path can meet its constraints.

Answer : C

BConfigure Link-LDP sessions between each PE-ABR and ABR-ABR pair.

CConfigure RSVP-TE LSPs in each area between each PE-ABR and ABR-ABR pair.

DConfigure T-LDP sessions with the tunneling option.

Answer : B
