Demo Questions

Question 1
Click the Exhibit button. 
  
R5 must advertise Subnet A into IS-IS so that Subnet A and Subnet B can communicate. Subnet B must be able to forward traffic to Subnet A and towards Area 
49.0001. However, R5 should not be able to route traffic from Subnet A to Area 49.0001. 
Referring to the exhibit, how would you solve this problem? 
  1. Configure Level 2 on all links in Area 49.0002.
  2. Configure the set protocols isis ignore-attached-bit parameter on R5.
  3. Configure the set protocols isis overload parameter on R6.
  4. Configure an export policy on R6 to reject all routes except Subnet B towards R5.
Correct answer: B
Question 2
Which transport mechanism is required for Layer 3 VPNs?
  1. GRE
  2. VXLAN
  3. IPsec
  4. MPLS
Correct answer: D
Question 3
Click the Exhibit button. 
  
Referring to the exhibit, RR1-RR4 are route reflectors. 
Which three routers would RR1 need to peer with if the no-client-reflect parameter has been configured? (Choose three.)
  1. R2
  2. R5
  3. RR4
  4. R6
  5. R1
Correct answer: ACE
Explanation:
Question 4
Click the Exhibit button. 
  
R1 and R2 are not forwarding the routes received from a remote PE to their customers. 
Referring to the exhibit, which parameter must be added to the configuration to allow the routes to be forwarded? 
  1. multipath multiple-as
  2. family inet-vpn
  3. multihop
  4. as-override
Correct answer: B
Question 5
You are asked to configure PIM-SM in your network. Your implementation must allow for load sharing between redundant RPs and, should an RP failure occur, the RP failover time should be minimized. 
Which two configuration tasks are required in this scenario? (Choose two.)
  1. Configure MSDP peering sessions between the routers designated as RPs.
  2. Configure the shared anycast address on the RPs as the primary address on the loopback interface.
  3. On the routers designated as RPs, configure the shared anycast address on the loopback interface.
  4. Configure at least two static RPs and bundle them in an RP redundancy group under [edit protocols pim].
Correct answer: BD
Question 6
In a carrier-of-carrier VPN model, which type of network layer reachability information is used for the MP-BGP signaling between CE and PE routers? 
  1. flow
  2. labeled-unicast
  3. unicast
  4. inet-vpn
Correct answer: D
Explanation:
In a Carrier-of-Carrier VPN environment, specify the inet-vpn address family and unicast traffic type to enable BGP to carry IPv4 network layer reachability information (NLRI) for VPN routes. References: http://www.juniper.net/documentation/en_US/junos15.1/topics/example/mpls-vpn-option2-configuration.html

Question 7
Click the Exhibit button. 
  
Referring to the exhibit, the Layer 2 VPN between PE-1 and PE-2 is not functioning properly. 
What must you do to solve the problem?
  1. Set the remote site identifier to 3.

  3. Set the local site identifier to 1.
  4. Set the remote site identifier to 5.
Correct answer: B
Question 8
Click the Exhibit button. 
  
Which two statements are true regarding the output shown in the exhibit? (Choose two.)
  1. Both ESIs are generated from the router ID.
  2. Both ESIs use the same VNI.
  3. The ESI 05:00:00:fe:4d:00:00:56:0e:00 is an auto-generated ESI.
  4. The ESI 00:24:24:24:24:24:24:24:24:24 is an auto-generated ESI. 
Correct answer: BC
Question 9
Click the Exhibit button. 
  
You have configured a BGP-signaled Layer 2 VPN with the configuration shown in the exhibit. 
Which two statements are true in this situation? (Choose two.)
  1. Remote site 1 is dual-homed. 
  2. The local site is site ID 1.
  3. The route-distinguisher is in the wrong format.
  4. Interface ge-0/0/l.512 is connected to the local site
Correct answer: AB
