Question 1

Click the Exhibit button.

Customer A is complaining that CE1 and CE2 cannot form an OSPF adjacency across your LDP Layer 2 circuit. The physical topology of the network is CE1-PE1-P-PE2-CE2. PE1's loopback is 192.168.5.1, P's loopback is 192.168.6.1, and PE2's loopback is 192.168.7.1.
Referring to the output in the exhibit, what is the problem?

A. incorrect PE-CE interface configuration

B. mismatched interface encapsulations

C. mismatched virtual circuit ID values

D. extended LDP neighbor not established

Correct Answer: C

Question 2

What is a limitation of LDP?

A. It requires a full mesh of LSPs throughout the network.

B. It requires a traffic engineering database (TED).

C. Traffic must follow explicitly configured paths.

D. It does not support traffic engineering.

Correct Answer: D

Question 3

The network design team has decided to activate multicast in the network. Auto-RP has been selected as the RP mechanism. Which PIM operational mode must be enabled in this network?

A. sparse mode

B. sparse-dense mode

C. dense mode

D. source specific multicast

Correct Answer: B

Referring to the exhibit, what are three operations performed by the service provider's PE routers? (Choose three.)

A. Maintain the customer's external routes.

B. Maintain the customer's /32 loopback internal routes.

C. Use MP-EBGP to send Customer Site 2's internal routes to CE-1.

D. Maintain routes internal to the provider's network.

E. Modify the VRF label assigned using MP-BGP.

Correct Answer: B,C,D

Question 5

Click the Exhibit button.

You work for ISP A, as shown in the exhibit, and must configure R1 to use load balancing across both available links for all routes to ISP B's network. You start by configuring this policy:
policy-statement load-balance {
then {
load-balance per-packet;
}
}
Which two commands do you use to finish the configuration? (Choose two.)

A. set routing-options forwarding-table export load-balance

B. set protocols bgp group isp-b multihop

C. set protocols bgp group isp-b multipath

D. set routing-options forwarding-table import load-balance

Correct Answer: A,C

Question 6

Which three statements are true about the BGP community attribute? (Choose three.)

A. Routing policies can be simplified using BGP communities.

B. Only well-known communities can be passed between AS networks.

C. Communities can be used to signal local preference in other AS networks.

D. There are three well-known communities.

E. Communities are used in the route selection process.

Correct Answer: A,C,D

Question 7

-- Exhibit --
Click the Exhibit button.
In the exhibit, R2 is receiving external routing information for the 192.168.16.0/24 prefix and is redistributing it into IS-IS. R1 has a policy that leaks the 192.168.16.0/24 route into Area 49.1111. R3 has a policy that leaks the 192.168.16.0/24 route into Area 49.2222. However, the IS-IS version of the route does not appear in R2's routing table.
Why does R3's route leaking policy appear not to be working?

A. The Up/Down bit is set to down for the prefix.

B. R2 already has better routing information for the prefix.

C. You can only leak routes from Level 2 to Level 1.

D. The external flag is set for the prefix.

Correct Answer: A

Question 8

-- Exhibit -

-- Exhibit -
Click the Exhibit button.
Your network has multiple LSPs between Router A and Router B, as shown in the exhibit. You add a new LSP between these routers with the following parameters:
LSP5: 20 Mbps; Priority 2 2
Assuming no link has 20 Mbps available, which LSPs are candidates for preemption by LSP5? (Choose two.)

A. LSP1

B. LSP4

C. LSP3

D. LSP2

Correct Answer: B,C

Question 9

Which statement correctly describes the function of a policer?

A. It determines the amount of bandwidth allocated to a queue.

B. It defines a set of parameters, including transmission rate, queue priority, delay buffers, and congestion management and avoidance.

C. It provides a first stage of congestion management by controlling the amount of traffic entering a device.

D. It writes a value into an outbound packet's CoS field according to the packet's forwarding class and loss priority.

Correct Answer: C

Question 10

Click the Exhibit button.

Using the configuration and topology in the exhibit, which statement is true?

A. Each LSR randomly selects the physical path to reach the loose hop R5 for the LSP.

B. Each LSR selects the lowest next-hop IP address to reach the loose hop on R5 for the LSP.

C. Each LSR uses the IGP to select the physical path to reach the loose hop on R5 for the LSP.

D. Each LSR selects the highest next-hop IP address to reach the loose hop on R5 for the LSP.

Correct Answer: C

Question 11

Which neighbor state indicates that two BGP neighbors have full connectivity?

A. Idle

B. Open Confirm

C. Established

D. Connect
