What is the primary role of the Designated Router (DR) on an OSPF multi-access network?

To reduce the number of adjacencies and LSAs on the network

To redistribute external routes into the OSPF domain

To compute the shortest path tree for all routers on the network

To translate OSPF routes between different areas

A network engineer is migrating a network from OSPFv2 to OSPFv3. The engineer needs to ensure that OSPFv3 can carry both IPv4 and IPv6 routes. Which feature of OSPFv3 allows this?

OSPFv3 uses address-family support to carry both IPv4 and IPv6 routes.

OSPFv3 uses the same Router ID for both IPv4 and IPv6, which enables dual-stack.

OSPFv3 uses the same LSA types as OSPFv2, which include IPv4 and IPv6 addresses.

OSPFv3 automatically carries both IPv4 and IPv6 routes without additional configuration.

What is the primary purpose of the OSPF link-state database (LSDB) on a router?

To store the routing table entries that are installed in the forwarding table

To maintain a list of all OSPF neighbors and their current state

To hold a collection of Link-State Advertisements that describe the network topology

To cache the shortest path tree computed by the SPF algorithm

Part of the OSPF domain, which makes up ~4% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~1–2 in this domain), expect 1–1 from this objective — we provide 29 practice questions to prepare you well beyond it.
