A network engineer is configuring IS-IS on a router and needs to advertise a directly connected IP prefix into the IS-IS domain. Which TLV should the engineer expect to see in the LSP to carry this prefix information?

TLV 22 (Extended IS Reachability)

TLV 135 (Extended IP Reachability)

What is a key network design implication of IS-IS PDUs being encapsulated directly into data-link frames?

IS-IS requires IP addressing to be configured on all interfaces

IS-IS can only run over Ethernet links

IS-IS can operate without IP addressing configured on interfaces

IS-IS requires a router ID to be configured

A network engineer is troubleshooting an IS-IS database synchronization issue on a broadcast segment. The engineer notices that a new router is not receiving all LSPs from the DIS. The engineer suspects that the CSNP sent by the DIS is incomplete. Which action should the engineer take to verify this suspicion?

Verify that the DIS is sending PSNPs to the new router.

Capture and analyze the CSNP PDU sent by the DIS to see if it contains all LSP IDs.

Check the sequence number of the CSNP to see if it is increasing.

Check the hello timer on the DIS to ensure it is sending hellos frequently.

A network engineer is troubleshooting an IS-IS adjacency on a broadcast network. The engineer notices that the Designated Intermediate System (DIS) is not sending CSNPs. What is the most likely impact of this issue?

Adjacencies will not form on the broadcast segment.

LSPs will not be flooded on the segment.

New routers on the segment will not be able to synchronize their databases efficiently.

The DIS election will be disrupted.

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 26 practice questions to prepare you well beyond it.
