A network engineer is troubleshooting an OSPFv3 issue where a router is not learning a route to a subnet in another area. The engineer runs 'show ospf3 database' and sees the Inter-Area-Prefix LSA (Type 3) for the subnet. However, the route is not in the routing table. What is the most likely cause?

The Type 3 LSA is being filtered by a route policy

The Type 3 LSA is not valid because the area is a stub

The SPF calculation has not run yet

The route is not being installed because the next hop is unreachable

What is the primary purpose of OSPFv3?

To enable IPv6 multicast group management

To provide a link-state routing protocol for IPv6 networks

To provide distance-vector routing for IPv6 networks

To replace BGP for exchanging routes between autonomous systems

Which statement correctly describes a key difference between OSPFv2 and OSPFv3?

OSPFv3 eliminates the need for a designated router on broadcast networks.

OSPFv3 runs directly over IPv6 and does not require IPv4 addresses for neighbor discovery.

OSPFv3 uses the same LSA types as OSPFv2, with no new LSA types introduced.

OSPFv3 uses a 32-bit router ID, while OSPFv2 uses a 16-bit router ID.

A security team requires that OSPFv3 adjacencies on a point-to-point link be authenticated to prevent rogue routers from joining the domain. The network uses Junos devices. Which authentication mechanism is supported by OSPFv3 on Junos?

MD5 authentication configured under the OSPFv3 interface

IPsec authentication using AH or ESP

OSPFv3 authentication field in the OSPF header

Simple password authentication configured under the OSPFv3 interface

Part of the Interior Gateway Protocols (IGPs) 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 1–2 from this objective — we provide 23 practice questions to prepare you well beyond it.
