You are monitoring an IS-IS adjacency on a Juniper router. The adjacency state is `Up`, but you notice that the neighbor is not receiving your hello packets. What is the most likely consequence?

The adjacency will remain Up but the routing table will be stale.

The adjacency will go Down after the hold time expires.

The adjacency will remain Up because the hold time is still valid.

The adjacency will transition to Initializing until hello packets are received again.

You are configuring two Juniper routers, R1 and R2, to run IS-IS. R1 is configured with `level 1` on its interface, and R2 is configured with `level 2`. Both routers are in the same area. What is the expected result of this configuration?

The routers will form a Level 2 adjacency and exchange Level 2 routes.

The routers will form a Level 1-2 adjacency and exchange both Level 1 and Level 2 routes.

The routers will not form an adjacency because their circuit types do not match.

The routers will form a Level 1 adjacency and exchange Level 1 routes.

A network engineer is troubleshooting an IS-IS adjacency that is flapping. The engineer has verified that the MTU is consistent, the authentication is correct, and the system IDs are unique. The engineer suspects that the hello interval is too short. What is the most appropriate action to confirm this suspicion?

Increase the hello interval and monitor the adjacency stability.

Increase the hold time and monitor the adjacency stability.

Decrease the hold time and monitor the adjacency stability.

Decrease the hello interval and monitor the adjacency stability.

Part of the IS-IS domain, which makes up ~15% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–9 in this domain), expect 1–1 from this objective — we provide 18 practice questions to prepare you well beyond it.
