  1. from prefix-list direct
  2. match local
  3. from protocol direct
  4. match protocol direct
  5. from protocol local
Correct answer: C
Question 2
Which of the following indicates the path over which an LSP's tail end router will return an RSVP RESV message?
  1. The IGP FIB.
  2. The Reservation State Block (RSB)
  3. The Path State Block (PSB)
  4. The opaque database.
Correct answer: C
Question 3
Click on the exhibit button below. 
    
With fast reroute enabled, and given the following: 
  • Two protected LSPs with the path R1-R2-R3 
  • Both LSPs enable facility bypass and link protection.  
When router R1 is the PLR, which router becomes the MP?
  1. Router R1
  2. Router R2
  3. Router R3
  4. Router R4
  5. Router R5
Correct answer: B
Question 4
Click on the exhibit button below. 
   
Given the output below, which of the following statements are true? (Choose three)
  1. A packet arriving with label 131066 and destined for prefix 10.10.10.243/32 will be forwarded out interface 1/1/4, with label 131070.
  2. LDP ECMP is enabled.
  3. The router’s system address is 10.10.10.242/32.
  4. There are multiple LSPs to reach FEC 10.10.10.244/32.
  5. The router cannot receive any unlabeled packets destined for prefix 10.10.10 223/32.
Correct answer: ABD
Question 5
Which of the following statements best describe MPLS fast reroute characteristics? (Choose two)
  1. Fast reroute requires you to manually define detour paths.
  2. Fast reroute provides path protection close to the failure point
  3. Fast reroute performs automatic path calculation and signaling.
  4. Fast reroute protects both primary and secondary paths.
Correct answer: BC
Question 6
During node protection signaling, the PLR knows the address of the MP from which of the following methods?
  1. The PLR issues a RSVP path message to the destination router to request the address of the MP.
  2. The PLR learns the address of the MP from the ERO.
  3. The PLR learns the address of the MP from the RRO
  4. The PLR learns the address of the MP from the targeted RSVP hello message.
  5. The PLR does not need to know the address of the MP.
Correct answer: C
Question 7
What is the significance of receiving a packet with the bottom MPLS label S bit set to 1?
  1. It results in forwarding based on the next packet header.
  2. It indicates that the label is the bottom of the MPLS label stack.
  3. It indicates that the label is the top of the MPLS label stack.
  4. Any LSR that receives an S bit set to 1 must discard the packet.
Correct answer: B
Question 8
Which command can be used to verify the LDP settings for label distribution and retention?
  1. show router ldp default
  2. show router ldp parameters
  3. show router ldp settings
  4. show router mpls settings
  5. show router mpls label-options
Correct answer: B
Question 9
Router R3 signals an LSP, reserving 1Gbps bandwidth on a 10Gbps link. RSVP configuration limits reservable bandwidth to 20 percent on the egress interface. 
Which of the following statements is true?
  1. The egress RSVP interface has 80 percent bandwidth unreserved.
  2. LSPs can reserve an additional 9.9 Gbps bandwidth on this RSVP interface.
  3. The head end reserves 100Mbps for the LSP
  4. The egress RSVP interface has 1 Gbps bandwidth unreserved.
Correct answer: D
Question 10
Click on the exhibit button below. 
   
Assuming that LSP R1-R2-R3 requests the default fast reroute configuration, which router becomes a DMP for the detour tunnels?
  1. Router R1
  2. Router R2
  3. Router R3
  4. Router R4
  5. Router R5
Correct answer: E
