Referring to the exhibit, R1 and R2 are directly connected using interface ge-1/1/0.

What happens as a result of the configurations?

A. No adjacency forms

B. Level 2 adjacency forms

C. Level 1 adjacency forms

D. Level 1 and Level 2 adjacencies form

-- Exhibit -Click the Exhibit button. Referring to the exhibit, you have an established RSVP LSP between R1 and R5 when you experience a link failure between R2 and R4.

Which two statements are correct? (Choose two.)

A. R2 sends a ResvTear message upstream to R1 signaling the link failure.

B. R2 sends a PathTear message upstream to R1 signaling the link failure.

C. R4 sends a ResvTear message downstream to R5 signaling the link failure.

D. R4 sends a PathTear message downstream to R5 signaling the link failure.

In an IS-IS network, which device represents the pseudo-node?

A. a designated intermediate system

B. an area border router

C. a router with an IS-IS export policy

D. a router connected to the backbone

Click the Exhibit button.

You run the command show interfaces terse ge-1/0/0 and see the output shown in the exhibit.

Why are two addresses being shown for this interface?

A. Two addresses are assigned in IPv6, one for the physical and one for the logical interface.

B. Two addresses are seen because the loopback address of the router is associated with the interface.

C. The two addresses being seen are the link-local and site-local.

D. An IPv6 address conflict is being seen; verify your interface configuration for problems.

Click the Exhibit button Referring to the exhibit, which policy would be applied to the 75.217.12.10 neighbor?

A. The my-statics policy would be applied.

B. The my-aggregates policy would be applied.

C. The my-specifics policy would be applied.

D. The my-statics, my-aggregates, and my-specifics policies would be applied.

Click the Exhibit button.

Referring to the exhibit, R1 and R2 are unable to form an IS-IS adjacency on interface ge-0/0/1.0. The ge0/0/1.0 interface has the appropriate address families enabled.

Which two actions will resolve the problem and allow the adjacency to come up? (Choose two.)

A. Change the R2 loopback interface address to 49.3154.1111.1111.1111.00.

B. Enable Level 2 adjacencies on R1.

C. Enable Level 1 adjacencies on R1.

D. Change the R2 loopback interface address to 49.3154.2222.2222.2222.00.

Which two statements are true about unified in-service software upgrade (ISSU)? (Choose two.)

A. Unified ISSU is supported only on dual Routing Engine (RE) platforms

B. To perform a unified ISSU, it is not necessary for the master RE and backup RE to be running the same version of the Junos OS

C. Unified ISSUE causes minimal disruption on both the control and forwarding planes

D. Graceful Routing Engine Switchover (GRES) and nonstop active routing (NSR) must be enabled to perform a unified ISSU
