Demo Questions

Question 1
You wish to advertise LDP labels for all local networks; which is the most effective policy statement to use?

  • A: from prefix-list direct
  • B: match local
  • C: from protocol direct
  • D: match protocol direct
  • E: from protocol local



Question 2
Which of the following indicates the path over which an LSP's tail end router will return an RSVP RESV message?

  • A: The IGP FIB.
  • B: The Reservation State Block (RSB)
  • C: The Path State Block (PSB)
  • D: The opaque database.



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?

  • A: Router R1
  • B: Router R2
  • C: Router R3
  • D: Router R4
  • E: Router R5



Question 4
Click on the exhibit button below. 
 
  

Given the output below, which of the following statements are true? (Choose three)

  • A: 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.
  • B: LDP ECMP is enabled.
  • C: The router’s system address is 10.10.10.242/32.
  • D: There are multiple LSPs to reach FEC 10.10.10.244/32.
  • E: The router cannot receive any unlabeled packets destined for prefix 10.10.10 223/32.



Question 5
Which of the following statements best describe MPLS fast reroute characteristics? (Choose two)

  • A: Fast reroute requires you to manually define detour paths.
  • B: Fast reroute provides path protection close to the failure point
  • C: Fast reroute performs automatic path calculation and signaling.
  • D: Fast reroute protects both primary and secondary paths.



Question 6
During node protection signaling, the PLR knows the address of the MP from which of the following methods?

  • A: The PLR issues a RSVP path message to the destination router to request the address of the MP.
  • B: The PLR learns the address of the MP from the ERO.
  • C: The PLR learns the address of the MP from the RRO
  • D: The PLR learns the address of the MP from the targeted RSVP hello message.
  • E: The PLR does not need to know the address of the MP.



Question 7
What is the significance of receiving a packet with the bottom MPLS label S bit set to 1?

  • A: It results in forwarding based on the next packet header.
  • B: It indicates that the label is the bottom of the MPLS label stack.
  • C: It indicates that the label is the top of the MPLS label stack.
  • D: Any LSR that receives an S bit set to 1 must discard the packet.



Question 8
Which command can be used to verify the LDP settings for label distribution and retention?

  • A: show router ldp default
  • B: show router ldp parameters
  • C: show router ldp settings
  • D: show router mpls settings
  • E: show router mpls label-options



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?

  • A: The egress RSVP interface has 80 percent bandwidth unreserved.
  • B: LSPs can reserve an additional 9.9 Gbps bandwidth on this RSVP interface.
  • C: The head end reserves 100Mbps for the LSP
  • D: The egress RSVP interface has 1 Gbps bandwidth unreserved.



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?

  • A: Router R1
  • B: Router R2
  • C: Router R3
  • D: Router R4
  • E: Router R5
