Click the Exhibit button. 
  
You have configured Layer 2 VPN stitching between two Layer 2 circuits on PE2, but traffic is not passing through the VPN. 
Referring to the exhibit, what is the problem?
  1. The unit 1 peer unit must be set to 0.
  2. The VLAN IDs must be lower than 512.
  3. The VLAN IDs must be different on each unit.
  4. The peer units must reference the VLAN IDs.
Correct answer: A
Question 2
You want to add a new OSPF area to your existing OSPF network, however, this area will not be directly connected to Area 0. Which feature would you use to complete this task?
  1. a routing policy
  2. not-so stubby area
  3. virtual link
  4. Type 10 LSA
Correct answer: C
Question 3
Click the Exhibit button. 
  
Referring to the exhibit, which statement is correct?
  1. IP address 192.168.16.5 is on a directly connected interface.
  2. Four routes have been leaked from the Level 2 area to the Level 1 area.
  3. The path to IP address 192.168.16.6 is currently unavailable.
  4. R1 has two Level 2 adjacencies and one Level 1 adjacency to other routers.
Correct answer: A
Question 4
Click the Exhibit button. 
  
Referring to the exhibit, what must be added to the existing configuration to ensure that per-prefix load balancing occurs?

  2. keep all
  3. multipath
  4. family inet unicast
Correct answer: C
Question 5

Question 6
You want to use IS-IS on a GRE interface where the underlying Layer 3 MTU is 1500. 
Which statement is correct in this scenario?
  1. IS-IS can be used because every IS-IS interface must be capable of transmitting packets at least as large as 1476 bytes, and the GRE header is 24 bytes.
  2. IS IS can be used, but the networking device directly attached to the circuit must be capable of fragmentation.
  3. IS-IS cannot be used, but the router can enable a GRE key that serves the same function as IS-IS.
  4. IS-IS cannot be used because the IS-IS hello is not allowed to be fragmented and has the DF bit set.
Correct answer: B

Referring to the exhibit, when building an interprovider VPN Option C between AS65100 and AS65200, which two parameters must be configured on the EBGP connection between PE1 and PE2? (Choose two.) 
  1. family inet-vpn unicast
  2. multihop
  3. family inet labeled-unicast

Question 8
Click the Exhibit button. 
  
You administer AS 65000, and have deployed a route reflector (RR1) in your network as shown in the exhibit. The traffic between AS 65001 and AS 65002 is going through the route reflector, even though it is not the best path. 
What will solve this problem?
  1. Change the LOCAL_PREF so that it uses the preferred path.
  2. Remove the nhs policy.
  3. Change the originator to be the preferred path.
  4. Change the IGP metric so it is lower on the preferred path.
Correct answer: B
Question 9
You are asked to deploy VPLS in your network as a new service for several customers, and you must identify the configuration and provisioning requirements for your customers. Which two statements are correct in this scenario? (Choose two.)
  1. CE interfaces facing the service prowler must be Ethernet interfaces.
  2. VLAN IDs defined on CE interfaces must be the same on both ends unless otherwise negotiated.
  3. CE interfaces facing the service provider must be Layer 3 interfaces.
  4. PE interfaces facing the core must have VPLS encapsulation enabled.
Correct answer: AB
Question 10
Click the Exhibit button. 
  
While logging in to routers on your network, you find the exact configuration shown in the exhibit on multiple devices. 
Which multicast RP strategy is being used in this scenario?
  1. embedded-rp
  2. auto-rp
