An engineer is troubleshooting an IS-IS network where some routers are missing routes. The engineer suspects that the LSP database is not synchronized. Which PDU type is used by a router to request missing LSPs from a neighbor?

CSNP (Complete Sequence Numbers PDU)

PSNP (Partial Sequence Numbers PDU)

Which IS-IS TLV is used to advertise the IPv4 addresses of a router's interfaces?

IP Interface Address TLV (TLV 132)

Extended IS Reachability TLV (TLV 22)

A network administrator is analyzing an IS-IS LSP and sees a TLV with type code 129. The value field contains a 4-byte IP address. What does this TLV represent?

The Protocols Supported TLV, which lists the network layer protocols.

The IP Interface Address TLV, which lists the router's interface IP addresses.

The IS Neighbors TLV, which lists neighboring routers.

The Area Addresses TLV, which lists the area addresses.

A network engineer is configuring IS-IS on a router and wants to ensure that the router advertises its area address to other routers. Which TLV will carry this information?

The Area Addresses TLV (type 1).

The Protocols Supported TLV (type 129).

The IP Interface Address TLV (type 129).

An engineer is analyzing an IS-IS packet and sees a TLV with type 2 and length 6. The value field contains a 6-byte system ID. What does this TLV represent?

The IP Interface Address TLV, which lists IP addresses.

The Extended IS Reachability TLV, which lists neighbor system IDs and metrics.

The Area Addresses TLV, which lists area addresses.

The IS Neighbors TLV, which lists the system IDs of neighboring routers.

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 16 practice questions to prepare you well beyond it.
