Juniper JNCIA JN0-692 Questions & Answers

• Question 151:

  You recently added your autonomous system to an existing BGP confederation. You notice that a route that had a local preference of 100 now has a local preference of 50. Which statement explains the change?

  A. BGP path attributes such as next hop, local preference, and MED are normally restricted to a single AS but are allowed to propagate throughout the confederation's AS members.

  B. The confederation has sub-ASs that require all IBGP routes to have a local preference of 50 or below.

  C. When your Junos devices joined the confederation, they lost IBGP connectivity to the route in question; the local preference reverted to 50 once the BGP peering established.

  D. The route is being shared through an EBGP peer, and the confederation is propagating the local preference from the peer.

  Correct Answer: A

• Question 152:

  

  Which two scenarios would explain the error shown in the exhibit? (Choose two.)

  B. The local router received a route withdrawal from the peer.

  C. Packets were dropped in the receive path of the peer router.

  D. The local router egress interface towards the peer was congested.

  Correct Answer: CD

  Which additional configuration would result in the creation of a (*, G) join for the other group (232.1.1.1)?

  A. Add relevant configurations for an SSM map.

  B. Enable PIM version 1 on interface xe-5/2/0.0.

  C. Configure another RP for the other group

  D. Enable PIM on all interfaces.

  A. The R2 interface is down.

  B. The ge-1/1/2.0 interface has IS-IS level 2 disabled.

  C. The ge-1/1/2.0 interface does not have family iso configured.

  D. The ge-1/1/2.0 interface has IS-IS level 1 disabled.

  Correct Answer: C

• Question 158:

  A. The hold-time interval is set too low.

  B. There is an MTU mismatch.

  C. The hold-time interval is set too high.

  D. The dead-interval is set too low.

  Correct Answer: B

• Question 159:

  

  You are asked to configure an EBGP peering, but the peering does not establish and transitions between the Connect and Active states.

  Referring to the exhibit, what is causing the problem?

  A. The number of messages from the BGP peer has exceeded the receive socket buffer.

  B. An incorrect local AS has been configured in the BGP group configuration.

  C. BGP is waiting to receive a keepalive or notification message from the peer.

• Question 160:

  

  PE-1 is not sending any routes to the CE router in the Cust routing instance. What is the reason?

  A. There is a mismatch in the target community and the route distinguisher.

  B. The vrf-import policy is only accepting direct routes.

  C. The as override parameter is causing an AS loop on the CE device.

  D. The vrf-export policy must be explicitly defined.

  Correct Answer: B
