Question 1
You are configuring OSPF and want to ensure that interface ge-0/0/3 is preferred over interface ge- 0/0/4.
Which statement is correct in this scenario?
  1. Configure ge-0/0/3 with a higher metric.
  2. Configure reference bandwidth.
  3. Configure a redistribution policy.
  4. Configure ge-0/0/4 with a higher metric.
Correct answer: D
Question 2
A BGP session shows the state as active.
What does the state indicate in this scenario?
  1. A keepalive message has been received.
  2. The BGP session is fully established and routes are being passed.
  3. The TCP connection is successful, and BGP is waiting for the OPEN message from its peer.
  4. The routes are still trying to establish a TCP connection.
Correct answer: D
Question 3
You do not want any spanning tree protocols operating in your environment, and you want to ensure that no BPDUs can be introduced into the environment.
Which statement is true in this scenario?
  1. You must run a spanning tree protocol to block BPDUs.
  2. Incoming BPDUs are blocked by default if a spanning tree protocol is not operating.
  3. You can block BPDUs without running a spanning tree protocol using Layer 3 control.
  4. Incoming BPDUs can only be blocked by the root bridge.
Correct answer: C
Question 4
Which two statements concerning IS-IS adjacencies are correct? (Choose two.)
  1. For Level 1 adjacencies, the area IDs can be different.
  2. For Level 2 adjacencies, the area IDs can be different.
  3. Level 2 routers can form an adjacency with Level 1 routers.
  4. Level 2 routers do not form adjacencies with Level 1 routers.
Correct answer: BC
Question 5
Which two statements about aggregate routes in the Junos OS are correct? (Choose two.)
  1. An aggregate route has a default next hop of an IP address.
  2. An aggregate route always shows as active in the routing table.

  4. Only one aggregate route can be configured for each destination prefix.
Correct answer: CD
Question 6
Exhibit.
     
Referring to the exhibit, Router-1 and Router-2 are failing to form an IS-IS adjacency.
What should you do to solve the problem?
  1. Remove the overloaded statement from Router-1.
  2. Change the IP subnet masks to match on the ge-0/0/2 interfaces of both routers.
  3. Remove the ISO address from ge-0/0/2 on Router-1.
  4. Change the ISO areas on the Io0 interfaces to match on both routers.
Correct answer: B
Question 7
Exhibit.
     
Referring to the exhibit, why is the route for 10.5.5.5 hidden?
  1. It is an L3VPN route.
  2. The next hop cannot be resolved.

  3. Type 3 summary LSAs
  4. Type 4 ASBR summary LSAs
Correct answer: CD
Question 9
Which two statements are true about high availability on Junos devices? (Choose two.)
  1. BFD is faster at detecting failures than default GRE or OSPF timers.
  2. NSR is independent of helper routers to assist the routing platform in restoring routing protocol information.
  3. NSR is dependent on helper routers to assist the routing platform in restoring routing protocol information.
  4. BFD is slower at detecting failures than default GRE or OSPF timers.
