Question 26

You were provided a network diagram that told you to number your network from the
191.255.0.0/16 space. OSPF is enabled and adjacencies are up, but no routers are learning any
routes. What can explain this?

A.The default OSPF export policies advertise nothing, so you need to apply export policy

B.The default OSPF import policy rejects all OSPF routes, so you need to apply import policy

C.You need to enable OSPF on the lo0 interface to provide a route to the RID of each router in the network

D.You need to modify the martian table with a 191.255.0.0/16 accept statement

The following ISO addresses illustrate the IS-IS address format:

49.0001.00a0.c96b.c490.00
49.0001.2081.9716.9018.00

NETs take several forms, depending on your network requirements. NET addresses are hexadecimal and range from 8 octets to 20 octets in length. Generally, the format consists of an authority and format Identifier (AFI), a domain ID, an area ID, a system identifier, and a selector. The simplest format omits the domain ID and is 10 octets long. For example, the NET address 49.0001.1921.6800.1001.00 consists of the following parts:

49—AFI

0001—Area ID

1921.6800.1001—System identifier

00—Selector

The system identifier must be unique within the network. For an IP-only network, we recommend using the IP address of an interface on the router. Configuring a loopback NET address with the IP address is helpful when troubleshooting is required on the network.

The first portion of the address is the area number, which is a variable number from 1 through 13 bytes. The first byte of the area number (49) is the authority and format indicator (AFI). The next bytes are the assigned domain (area) identifier, which can be from 0 through 12 bytes. In the examples above, the area identifier is 0001....

Question 30

Click the Exhibit button.

In the exhibit, each IP subnet in the campus environment is associated with a unique VLAN ID.
Which action will ensure that Host C will communicate with Host A and Host B?

A.Configure an IRB interface for each VLAN and associate it with its corresponding VLAN

B.Configure all switch ports connecting to the host devices as access ports associated with a common VLAN

C.Configure all switch ports connecting to the host devices as trunk ports associated with all VLANs

D.Configure a port-based ACL that permits inter-VLAN routing for all configured VLANs
