A network engineer is monitoring an IS-IS broadcast segment. The DIS is Router A. The engineer notices that Router A is sending CSNPs every 10 seconds. What is the purpose of these periodic CSNPs?

To ensure all routers on the segment have a synchronized link-state database.

To elect a new DIS if the current DIS fails.

To flood the pseudonode LSP to all routers.

To establish adjacencies with new routers on the segment.

A network engineer is reviewing the IS-IS configuration on a broadcast segment. The current DIS has a priority of 64. The engineer wants to ensure that a specific router, Router Z, becomes the DIS. The engineer sets Router Z's priority to 127. What must the engineer also do to ensure Router Z becomes the DIS?

Change the MAC address of Router Z to be lower than the current DIS's MAC address.

Restart the IS-IS process on all routers on the segment to force a new election.

Configure Router Z as the backup DIS on the segment.

Wait for the current DIS to fail or be shut down, since IS-IS does not preempt the current DIS.

A service provider has a broadcast segment with six routers. The DIS is Router X. The network engineer is analyzing the LSPs generated on this segment and notices that the DIS generates a pseudonode LSP. What is the primary purpose of this pseudonode LSP?

To list all the LSPs in the DIS's database for synchronization purposes.

To represent the broadcast segment as a single virtual node, reducing the number of adjacencies that must be advertised.

To advertise the DIS's own interfaces and IP addresses to all other routers on the segment.

To provide a backup path in case the DIS fails.

A network engineer is analyzing the IS-IS database on a broadcast segment. The engineer sees an LSP with an ID that includes a non-zero system ID in the last byte. What does this LSP represent?

An LSP from a non-DIS router on the segment.

An LSP from a router on a point-to-point link.

The DIS's own LSP advertising its interfaces.

The pseudonode LSP generated by the DIS for the broadcast segment.

Designated Intermediate System (DIS) JN0-364 Practice Questions (Page 1)

Part of the Intermediate System to Intermediate System (IS-IS) domain, which makes up ~12% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–1 from this objective — we provide 23 practice questions to prepare you well beyond it.
