Question 56

You have been asked to evaluate how EIGRP is functioning in a customer network.

What percent of R1's interfaces bandwidth is EIGRP allowed to use?

A.20

B.10

C.40

D.30

Question 57

Refer to the exhibit.

R1 and R2 are unable to establish an EIGRP adjacency. Which action corrects the problem?
d

A.Change the EIGRP router-id value on one of the routers so that the values on the two routers are different.

B.Change the autonomous system number on one of the routers so that each router has different values.

C.Add the no auto-summary command to the R2 configuration so that it matches the Rl configuration.

D.Chang the IP address and subnet mask on R2 so that it is on the same subnet as R1.

Question 58

Refer to the exhibit. Which interoperability technique implemented on the dual-stack routers would allow connectivity between IPv6 sites across automatic created tunnels using the 2002::/16 prefix?

A.GRE tunnel

B.NAT-PT

C.Dual Stack

D.6to4 tunnel

E.ISATAP tunnel

Question 59

Refer to the exhibit. Which networking challenge is the most important issue to address to enable optimal communication between the networks at Company A and Company B?

A.unicast flooding

B.IPv4 MTU

C.IPv4 fragmentation

D.asymmetric routing

E.UDP latency

Question 60

Route.com is a small IT corporation that is attempting to implement the network shown in the exhibit.
Currently the implementation is partially completed. OSPF has been configured on routers Chicago and NewYork. The SO/O interface on Chicago and the SO/1 interface on NewYork are in Area 0. The loopbackO interface on NewYork is in Area 1. However, they cannot ping from the serial interface of the Seattle router to the loopback interface of the NewYork router. You have been asked to complete the implementation to allow this ping.
ROUTE.com's corporate implementation guidelines require:
* The OSPF process ID for all routers must be 10.
* The routing protocol for each interface must be enabled under the routing process.
* The routing protocol must be enabled for each interface using the most specific wildcard mask possible.
* The serial link between Seattle and Chicago must be in OSPF area 21.
* OSPF area 21 must not receive any inter-area or external routes.

Correct Answer:

Here is the solution below:
Explanation/Reference:
Explanation:
Note: In actual exam, the IP addressing, OSPF areas and process ID, and router hostnames may change, but the overall solution is the same.
Seattle's S0/0 IP Address is 192.168.16.5/30. So, we need to find the network address and wildcard mask of 192.168.16.5/30 in order to configure the OSPF.
IP Address: 192.168.16.5 /30
Subnet Mask: 255.255.255.252
Here subtract 252 from 2565, 256-252 = 4, hence the subnets will increment by 4.
First, find the 4th octet of the Network Address:

The 4th octet of IP address (192.168.16.5) belongs to subnet 1 (4 to 7).
Network Address: 192.168.16.4
Broadcast Address: 192.168.16.7
Lets find the wildcard mask of /30.
Subnet Mask: (Network Bits - 1's, Host Bits - 0's)
Lets find the wildcard mask of /30.

Now we configure OSPF using process ID 10 (note the process ID may change to something else in real exam).
Seattle>enable
Password:
Seattle#conf t
Seattle(config)#router ospf 10
Seattle(config-router)#network 192.168.16.4 0.0.0.3 area 21
One of the tasks states that area 21 should not receive any external or inter-area routes (except the default route).
Seattle(config-router)#area 21 stub
Seattle(config-router)#end
Seattle#copy run start
Chicago Configuration:
Chicago>enable
Password: cisco
Chicago#conf t
Chicago(config)#router ospf 10
We need to add Chicago's S0/1 interface to Area 21
Chicago(config-router)#network 192.168.16.4 0.0.0.3 area 21
Again, area 21 should not receive any external or inter-area routes (except the default route).
In order to accomplish this, we must stop LSA Type 5 if we don't want to send external routes. And if we don't want to send inter-area routes, we have to stop LSA Type 3 and Type 4. Therefore we want to configure area 21 as a totally stubby area.
Chicago(config-router)#area 21 stub no-summary
Chicago(config-router)#end
Chicago#copy run start
The other interface on the Chicago router is already configured correctly in this scenario, as well as the New York router so there is nothing that needs to be done on that router.
