Question # 33

In an OSPF network, which of the following is NOT a result of manual summarization on an ABR?

It can reduce the topological database size.

It can reduce the size of the route table.

It can reduce the number of Summary LSAs.

It can reduce the number of Router LSAs.

Question # 34

An Alcatel-Lucent 7750 SR is configured with an export policy to redistribute a loopback prefix into OSPFv3.

What type of LSA advertises the prefix to the other OSPFv3 routers in the same area?

Router LSA

AS External LSA

Intra-Area Prefix LSA

Inter-Area Prefix LSA

Network LSA

Router R2 uses IS-IS to advertise the network 192.168.3.0/24 to R1. How can router R1 discard the route?

Use an import policy and a prefix list on router R2.

Use an export policy and a prefix list on router R1.

Use an import policy and a prefix list on router R1.

Router R1 cannot discard the route because IS-IS does not support import policies.

Question # 36

Before the link failure, all routers have operational OSPF adjacencies between them and there is a BFD session between routers R1 and R3.

After the link failure, which of the following affects the IGP convergence time?

The convergence time depends on the value of the OSPF hello timers on routers R1 andR3.

The convergence time depends on the value of the OSPF hello timers and Dead interval on routers R1 and R3.

The convergence time depends on the value of the BFD interval and multiplier settings on routers R1 andR3.

The convergence time depends on the time taken by the switches to detect the link failure.

Question # 37

Click on the exhibit.

An OSPFv3 router is attached to a non-OSPF domain that includes networks 2001:DB8:8::/64.2001 .DB8:9::/64 and 2001 :DB8:A::/64. Other routers in the OSPF domain see the prefix 2001, DB8:8::/64, but not the other two prefixes.

What could cause this?

The router is not configured as an asbr.

The router is not configured as an NSSA.

The export policy is not applied to OSPFv3.

The prefix list should be 2001:DB8:8::/46

Question # 38

Click the exhibit button.

The OSPF packets shown have been exchanged between two neighbors. What state is the OSPF adjacency in?

The adjacency state is two way because both routers have received a database description packet.

The adjacency is in the exchange state. The next step is to exchange link state request and link state update packets.

The adjacency is in the ex start state. The routers have exchanged database description packets, but still have to negotiate the starting sequence number.

The adjacency state is full. The routers are exchanging database description packets to notify each other that all link state advertisements have been received.

Question # 39

TCP source port

Prefix list

Protocol type

Question # 40

An Alcatel-Lucent 7750 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.
