A network engineer is troubleshooting an IS-IS database synchronization issue on a point-to-point link. The engineer sees that the routers are exchanging LSPs, but the databases are not converging. The engineer captures the traffic and sees that the routers are sending PSNPs. What is the most likely purpose of these PSNPs?

To elect the DIS on the point-to-point link.

To advertise the complete list of LSPs in the database.

To establish the adjacency between the routers.

To acknowledge received LSPs and request missing LSPs.

What is the primary purpose of a Link State PDU (LSP) in IS-IS?

To discover and maintain adjacencies

To request specific LSPs from a neighbor

To advertise the complete list of LSPs in the database

To carry link-state information about a router

A network engineer is analyzing an IS-IS LSP PDU and sees that the LSP ID is 1921.6800.1001.01-00. The engineer also sees that the PDU contains an IS Reachability TLV (TLV 2) with a list of neighbors. What can the engineer conclude about this LSP?

This is a normal router LSP generated by the router itself.

This is a pseudonode LSP generated by the DIS on a broadcast network.

This is an LSP that has been purged from the database.

This is a Level 2 LSP because the pseudonode ID is non-zero.

A network administrator is configuring IS-IS on a router and wants to verify that the router is sending hello PDUs with the correct parameters. The administrator captures a packet and sees the following fields in the IIH PDU: Circuit Type, Source ID, Holding Time, PDU Length, and a set of TLVs. Which TLV would the administrator expect to see in this IIH PDU to identify the router's area?

IP Interface Address TLV (TLV 6)

Protocols Supported TLV (TLV 129)

Extended IS Reachability TLV (TLV 22)

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.

A network administrator is configuring IS-IS on a router and wants to ensure that the router can form adjacencies with both Level 1 and Level 2 neighbors. The administrator is looking at the IIH PDU and wants to verify that the router is sending the correct circuit type. Which field in the IIH PDU should the administrator check?
