NEW QUESTION 2
You are tasked to enable LDP on many of the interfaces on the Cisco CRS-3 router, and because there are many interfaces that need to have LDP enabled, you mistakenly did not enable LDP on all the required interfaces. To prevent this issue from happening again in the future, what could you do the next time you need to enable LDP on many interfaces?

• A. use the mpls ldp auto-config command under the IGP routing process
• B. use the mpls ldp sync command under the IGP routing process

NEW QUESTION 5
Implementing IPoDWDM interfaces on Cisco CRS routers eliminates the need for which network component?

• A. ROADM
• B. external transponders

NEW QUESTION 6
Scenario:




From PE8 router, what is the label action used to reach the P2 loopback 0 interface 10.0.2.1/32?

• A. Swap label 35 with label 16004
• B. Push label 16004
• C. Pop label 35
• D. Pop label 16009
• E. Push Label 16009
• F. Swap label 35 with label 16009

Answer: C

Explanation: show mpls forwarding-table , find prefix 10.0.2.1 and you will see there under outgoing Label "Pop Label" (This is actually logic because the prefix is directly connected and therefore the packet will forward without label). If the router should forward any packet to that prefix, the packet should be received with Local label on PE8 (Local Label = 35), the router will remove it and forward it without Label.

NEW QUESTION 7
Refer to the exhibit.

A network engineer who is working for an ISP wants to override the QoS that comes from the customer. The engineer wants to set a QoS value of 5 for all traffic. What are two reasons why the configuration is not working? (Choose two.)

• A. The service-policy command should point to the service policy, not to the class map
• B. The set command should reference CoS instead of MPLS EXP bits
• C. The service-policy configuration should be set as output
• D. The policy-map configuration needs to reference class-map Custom1
• E. The number 350 in the xconnect command should appear after the encapsulation type

Answer: AD

NEW QUESTION 8
Scenario:




On the PE8-router what is the label value used to reach the 10.7.1.1/32 network prefix?

• A. 10.0.2.1:0
• B. imp-null
• C. 16024
• D. 128

Answer: C

Explanation: Issue on PE8: show mpls forwarding-table
Look for the "Outgoing Label" not the "Local Label" for the prefix 10.7.1.1/32. You will notice that the Label value is 16024.

NEW QUESTION 9
Which driver uses an IntServ QoS model in an MPLS TE enabled service provider network?

• A. DSCP, which requires signaling across the provider network
• B. RSVP, which enables bandwidth guarantees across a provider network
• C. RSVP, which enables per-hop behavior across a provider network
• D. DSCP, which enables bandwidth guarantees across a provider network

Answer: B

NEW QUESTION 10
Which two options are true regarding the Pipe and Short Pipe MPLS tunneling models? (Choose two.)

• A. In Short Pipe mode QoS is done on the PE-to-CE link based on the customer’s PHB markings
• B. In Pipe mode QoS is done on the PE-to-CE link based on the service provider’s PHB markings
• C. In Pipe mode QoS is done on the PE-to-CE link based on the customer’s PHB markings
• D. In Short Pipe mode QoS is done on the PE-to-CE link based on the service provider’s PHB markings
• E. Short Pipe mode does not need MPLS usage, but Pipe mode does

Answer: AB

NEW QUESTION 11
