Question 141

Click on the exhibit.

All links have 1 Gbps unreserved bandwidth initially and all LSPs have the least-fill feature enabled. After the two LSPs have been signaled as shown, two additional LSPs are configured. LSP-3 is signaled first with 50Mbps reserved. LSP-4 is signaled after with 400Mbps reserved.
Which paths will CSPF choose for LSP-3 and LSP-4?

A.Both LSP-3 and LSP-4 take R1-R3-R5-R6.

B.Both LSP-3 and LSP-4 take R1-R2-R4-R6.

C.CSPF randomly chooses one of the equal cost paths for the two LSPs.

D.LSP-3 takes R1-R2-R4-R6 and LSP-4 takes R1-R3-R5-R6.

E.LSP-3 takes R1-R3-R5-R6 and LSP-4 takes R1-R2-R4-R6.

Question 142

Which of the following best describes the features of Classless Inter-Domain Routing (CIDR)?

A.Automatic summarization and the use of IP addresses that use any number of bits for the network portion of the address.

B.Automatic summarization and the use of IP addresses that use a fixed number of bits for the network portion of the address.

C.Manual summarization and the use of IP addresses that use a fixed number of bits for the network portion of the address.

D.Manual summarization and the use of IP addresses that use any number of bits for the network portion of the address.

Question 143

Refer to the exhibit below. IS-IS IPv6 routing is configured in the network with globally routed addresses as shown.
How many routes will R4 have in its IPv6 route table?

A.4

B.6

C.2

D.1

E.3

F.7

Question 144

An LSP path is configured as follows:
- Shared-explicit reservation style
- Make-before-break (MBB) enabled
- 500Mpbs bandwidth reserved on a 1Gbps link
With 100Mbps of unreserved bandwidth remaining, the operator increases the LSP-path's bandwidth reservation to 900Mbps.
What happens to the existing LSP?

A.After 5 failed attempts to find the bandwidth requested, the head end disables the LSP.

B.CSPF looks for the delta bandwidth, implementing make-before-break.

C.CSPF looks for the delta bandwidth, taking down the first path if necessary.

D.CSPF looks for the entire bandwidth requested, implementing MBB.

Question 145

A.Level 0

B.Level 2

C.Level 1/2

D.Level 0/1

E.Level 1
