Demo Questions

Question 1
Click the Exhibit button. 
  
Referring to the exhibit, what must be added to the existing configuration to ensure that per-prefix load balancing occurs? 
  1. multihop
  2. keep all
  3. multipath
  4. family inet unicast
Correct answer: A
Question 2
You are asked to configure a new Layer 3 VPN. 
In this scenario, which routing-instance type must be used? 
  1. vpls
  2. evpn
  3. vrf
  4. 12vpn
Correct answer: C
Question 3
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 4
Which transport mechanism is required for Layer 3 VPNs?
  1. GRE
  2. VXLAN
  3. IPsec
  4. MPLS
Correct answer: D
Question 5
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
Question 6
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 7
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 8
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?

  2. Set the local site identifier to 3.
  3. Set the local site identifier to 1.
  4. Set the remote site identifier to 5.
Correct answer: B
Question 9
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 10
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.
