Question 1 of 27

2. Consider the following redistribution configuration on a router:

router ospf 1 redistribute eigrp 1 route-map EIGRP2OSPF ! route-map EIGRP2OSPF deny 10 ! route-map EIGRP2OSPF permit 20 match ip address prefix-list SET-TYPE-1 set metric-type 1 ! route-map EIGRP2OSPF permit 30 match ip address prefix-list SET-METRIC set metric 22 ! ip prefix-list SET-TYPE-1 permit 0.0.0.0/0 ge 24 le 24 ip prefix-list SET-METRIC permit 0.0.0.0/0 ge 25 le 30

Question 2 of 27

3. Consider the following configuration on the router:

router eigrp 1 default-metric 10000 100 255 1 1500 redistribute ospf 1 ! router ospf 1 redistribute eigrp 1 subnets !

Given this configuration, which of the following statements is TRUE? Select the BEST answer.

Only OSPF has the capability to query EIGRP for dynamically learned routing information

Both EIGRP and OSPF will query the RIB for dynamically learned routes from the other protocol

Both EIGRP and OSPF will query the RIB for dynamically learned, connected, and static routes from the other protocol

Both EIGRP and OSPF will query the RIB for dynamically learned and connected routes from the other protocol

EIGRP and OSPF will query each other for all dynamically learned routing information

Only EIGRP has the capability to query OSPF for dynamically learned routing information

Question 3 of 27

4. Click on the Exhibit.

Router R3 has been configured to filter even subnets using the configuration illustrated in the exhibit. However, following this configuration, the show ip route command shows that these subnets are still being received by the router. What changes should be made to ensure that the applied configuration works? Select the BEST answer.

This is a limitation of OSPF; the distance command only works when used with EIGRP. For OSPF, only a distribute-list can be used to filter routes

Modify the configuration by adding the ip ospf database-filter in EVEN-SUBNET-FILTER router configuration command to the existing configuration to filter the subnets and their LSAs

Modify the configuration using and specify a route map that includes the match route-source 150.1.1.2 match clause to match routes from neighbor 150.1.1.2

Modify the configuration by also adding the distribute-list command to the configuration. This command would match the ACL named EVEN-SUBNET-FILTER that will also be specified in the distance command configuration

Issue the show ip ospf neighbor command and modify the distance command configuration to use the router ID of the neighbor as printed in the output of the show ip ospf neighbor command

The configuration is valid; you must issue the clear ip ospf filtering command to reset the OSPF filtering process. Following that, the even subnets specified in the access list will be filtered by OSPF

Question 15 of 27

16. Click on the Exhibit.

Referencing the topology illustrated in the exhibit, which of the following would be the most efficient manner to allow the EIGRP and OSPF routing domains to communicate? Select the BEST answer.

Configure OSPF to redistribute EIGRP using the redistribute eigrp 1 subnets command and then configure EIGRP to redistribute OSPF using the redistribute ospf 1 metric 10000 100 255 1 1500 command

Configure the redistribute connected metric 10000 100 255 1 1500 route-map INTERFACES command under EIGRP and the redistribute eigrp 1 subnets command under OSPF. The INTERFACES route map specified in the EIGRP configuration should match all OSPF subnets

Configure mutual redistribution between OSPF and EIGRP with filtering using the redistribute eigrp 1 subnets route-map EIGRP-FILTER command under OSPF and the redistribute ospf 1 metric 10000 100 255 1 1500 route-map OSPF-FILTER command under EIGRP. The route maps should filter prefixes using either ACLs, prefix lists or route tags

Configure the redistribute connected subnets route-map INTERFACES command under OSPF and the redistribute ospf 1 metric 10000 100 255 1 1500 command under EIGRP. The INTERFACES route map specified in the OSPF configuration should match only the 172.16.1.0/24 subnet

Configure static routes to the OSPF networks on routers R1 and R2 and redistribute them into EIGRP using the redistribute static metric 10000 100 255 1 1500 command; then force R1 and R2 to generate a default route to the rest of the OSPF network using the default-information originate always command

Question 17 of 27

18. Consider the following EIGRP route redistribution configuration on a router:

router eigrp 1 redistributed connected redistribute static redistribute eigrp 2 redistribute ospf 1

Given the configuration above, which of the following statements is TRUE in regards to redistributing routes into EIGRP? Select THREE answers.

Because the seed metric is not specified using the default-metric command, or the metric is not specified during redistribition using the redistribute [protocol] metric command, only static and connected routes are redistributed

Because the seed metric is not specified using the default-metric command, and the metric is not specified during redistribition using the redistribute [protocol] metric command, no routes are redistributed

Because the seed metric is not specified using the default-metric command, and the metric is not specified during redistribution using the redistribute [protocol] metric command, all routes are redistributed and assigned a default metric of infinity

Question 18 of 27

19. Click on the Exhibit.

Given the output in the exhibit, the following configuration is applied to the router:

router ospf 1 redistribute bgp 2 subnets

Given this configuration, which of the following is TRUE? Select the best answer.

The route will not be redistributed into OSPF because it has a route metric of 0

In order for the route to be redistributed, the redistribution configuration should be changed to redistribute bgp 2 subnets metric 1 under OSPF process 1 in router configuration mode

It is not possible for a dynamic route to have a metric of 0. Cisco IOS software will ignore the redistribution configuration

The route will be redistributed into OSPF and assigned a default metric of 0

The route will be redistributed into OSPF and assigned a default metric of 20

Question 19 of 27

All three networks would be redistributed into OSPF

Only network 10.1.1.0/24 would be redistributed into OSPF

You cannot specify a route-map when redistributing EIGRP into OSPF; the configuration is invalid

None of the networks would be redistributed into OSPF

Only networks 10.1.1.0/25 and 10.1.1.0/30 would be redistributed into OSPF

Redistribute internal routes with a higher metric ensuring that if routes are redistributed back into the original domain, they are less preferred

When possible, redistribute internal routes with a higher administrative distance value than that of the route source

Use route tagging or other filters to ensure that only routes external to the route source or prefixes that originate from the route source domain are redistributed

Question 24 of 27

Question 25 of 27

26. Click on the Exhibit.

Given the configuration shown in the exhibit, which of the following statements are FALSE? Select FOUR answers.

EIGRP routes will be redistributed into OSPF with a default metric of 20 for dynamically learned routes and a default metric of 0 for connected EIGRP routes

RIP routes will be redistributed into EIGRP with a default metric of 10000 100 255 1 1500

EIGRP routes will be redistributed into OSPF with a default metric of 20 for dynamically learned and connected routes

EIGRP will redistribute subnets within the 10.0.0.0/8 network learned by both RIP and OSPF

The RIP routes redistributed into EIGRP will NOT be redistributed into OSPF given the redistribution configuration

RIP routes will be redistributed into EIGRP with a default metric of 5000 500 255 1 1500

Because both OSPF and RIP are routing for the 10.0.0.0/8 network, EIGRP will redistribute only the OSPF subnets within this major network because OSPF has the higher administrative distance
