Question # 34

OSPF requires that routers in the same area have the same link state database (LSDB). As the number of routes on the network increases, some routers cannot carry so much routing information due to limited system resources. This state is called database overflow. If the Isdb-overflow-limit number 7 command is run on all routers on an OSPF network, which of the following conditions are likely to cause routers to enter the overflow state?

Options:

A.

The number of Type 4 LSAs exceeds 7.

B.

The number of Type 5 LSAs exceeds 7.

C.

The number of Type 7 LSAs exceeds 7.

D.

The number of Type 3 LSAs exceeds 7.

Both VLAN aggregation and MUX VLAN are deployed on the enterprise network shown in the figure.

    All switch interfaces connected to terminals are access interfaces.

    Given this, match PC1 to PC4 with the hosts or servers they can access on the network.

(Note: A host cannot be matched with itself. For example, PC1 cannot match PC1. Tokens can be reused.)

Question # 41

On the network shown in the figure, IS-IS runs on R1, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. The import-route isis level-2 into level-1 command is configured on R2.

In AS 65000, R1, R3, R4, and R6 each establish iBGP peer relationships with R2 and R5. R2 and R5 are Route Reflectors (RRs), and R1, R4, R3, and R6 are clients.

An iBGP peer relationship is established between R2 and R5, and the same cluster ID is configured. The iBGP peer relationships are established using Loopback0. The IP address of Loopback0 on each router is 10.0.X.X/32, where X is the router number.

R1 and R4 import the external route 192.168.1.0/24 to BGP through the import-route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import-route command.

Which of the following statements are true?

Options:

A.

The BGP routing table of R3 contains one valid route to 192.168.2.0/24.

B.

The BGP routing table of R5 contains two valid routes to 192.168.1.0/24.

C.

The BGP routing table of R2 contains three valid routes to 192.168.1.0/24.

D.

The BGP routing table of R4 contains three valid routes to 192.168.2.0/24.
