Question # 5

An operator configures anNokia7750 SR with a loopback interface and IPv6 address. The operator then configures a routing policy to redistribute the loopback prefix into OSPFv3. What type of LSA is used to advertise the route to other OSPFv3 routers in the same area?

Router LSA

AS External LSA

Intra-Area Prefix LSA

Inter-Area Prefix LSA

Network LSA

None of the statements are correct.

Question # 8

AnNokia7750 SR receives a route via an IS-IS LSP with internal reach ability, and receives the same route via an OSPF type 5 LSA. If al protocol preferences are default, which route will be installed in the route table?

The route learned via IS-IS will be installed.

The route learned via the OSPF type 5 LSA will be installed.

Both routes will be installed, if ECMP is enabled.

Both routes will be installed, regardless of whether ECMP is enabled.

Question # 13

An OSPF router receives an update in which the sequence number, age, and checksum are the same as the entry already in the topological database. What action is taken by the router?

The link state information is not populated in the database but is forwarded to all neighbors

The link state information already in the database is overwritten and the age is reset

The link state information is not populated in the database and an acknowledgement is sent

The link state information is regarded as old and nothing is done.
