Questions # 241:

What is the primary purpose of classless interdomain routing (CIDR)?

Options:

A.

To support classful routing protocols.

B.

To allow IP routes to be defined using any number of bits for the network portion of the address.

C.

To allow interdomain routing between an IGP and EGP such as OSPF and BGP.

D.

To simplify the allocation of IP address space by defining a fixed size for the network portion of the address for each of the address classes.

Question # 242

What can you deduce from the show command on router R6?

Options:

A.

The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.5.

B.

The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment; however, this command does not indicate whether 10.10.10.3 or 10.10.10.5 is the DR or BDR.

C.

The router R6 interface is in a multi-access segment. It is the BDR, which is why it is not adjacent to the other routers.

D.

The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.3.

Question # 244

Given the diagram below, what path will traffic follow from router R6 to router R3, and from router R3 to router R6, if IS-IS is the routing protocol? The numbers beside the links are the metrics for that link.

Options:

A.

Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3- R2-R5-R6).

B.

Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3-R4-R2-R5-R6).

C.

Router R6 to router R3 will follow (R6-R5-R2-R3). Router R3 to router R6 will follow (R3-R4-R7-R5-R6).

D.

Router R6 to router R3 will follow (R6-R5-R7-R4-R3). Router R3 to router R6 will follow (R3-R4-R7-R5-R6).

Questions # 247:

What is wrong with the following filter configuration from an Alcatel-Lucent 7750 SR?

RTR-B# configure filter

RTR-B>config>filter# ip-filter 1 create

RTR-B>config>filter>ip-filter$ entry 1 create

RTR-B>config>filter>ip-filter>entry$ match src-ip 172.2.0.0/16

RTR-B>config>filter>ip-filter>entry# action drop

RTR-B# configure router interface toRTR-A

RTR-B>config>router>if# egress

RTR-B>config>router>if>egress# filter ip 1

Options:

A.

There is nothing wrong with this filter

B.

The filter should be applied to the ingress and not the egress.

C.

The mask cannot be a "/" value, it must be in dotted decimal.

D.

All traffic is being blocked

Questions # 248:

Options:

A.

traceroute 10.2.3.1

B.

traceroute 10.2.3.1 next-hop 10.1.2.1

C.

traceroute next-hop 10.1.2.1

D.

traceroute does not work on the Alcatel-Lucent 7750 SR.

Options:

A.

Use a prefix list on router R1 to discard all ingress IS-IS routes.

B.

Use an export policy and prefix list on router R1.

C.

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

D.

This is not possible because IS-IS cannot use import policies.
