Question 6 of 154

Scenario:
You have been brought in to troubleshoot an EIGRP network. You have resolved the initial issue between routers R2 and R4, but another issue remains. You are to locate the problem and suggest solution to resolve the issue.
The customer has disabled access to the show running-config command.
Exam 300-135: Question 6 - Image 1

The network segment between R2 and R4 has become disconnected from the remainder of the network. How should this issue be resolved?

A.

Change the autonomous system number in the remainder of the network to be consistent with R2 and R4.

B.

Move the 192.168.24.0 network to the EIGRP 1 routing process in R2 and R4.

C.

Enable the R2 and R4 router interfaces connected to the 192.168.24.0 network.

D.

Remove the distribute-list command from the EIGRP 200 routing process in R2.

E.

Remove the distribute-list command from the EIGRP 100 routing process in R2. B

Correct Answer:

When issuing the "show ip eigrp neighbor" command (which is about the only command that it lets you do in this question) you will see that all other routers are configured for EIGRP AS 1. However, the 192.16824.0 network between R2 and R4 is incorrectly configured for EIGRP AS 100:

Question 7 of 154

Scenario:
You have been asked by your customer to help resolve issues in their routed network. Their network engineer has deployed HSRP. On closer inspection HSRP doesn't appear to be operating properly and it appears there are other network problems as well. You are to provide solutions to all the network problems.
Exam 300-135: Question 7 - Image 1

You have received notification from network monitoring system that link between R1 and R5 is down and you noticed that the active router for HSRP group 1 has not failed over to the standby router for group 1. You are required to troubleshoot and identify the issue.

A.

There is an HSRP group track command misconfiguration

B.

There is an HSRP group priority misconfiguration

C.

There is an HSRP authentication misconfiguration

D.

There is an HSRP group number mismatch

E.

This is not an HSRP issue; this is routing issue. A

Correct Answer:

When looking at the HSRP configuration of R1, we see that tracking has been enabled, but that it is not tracking the link to R5, only the link to R2:

R1 should be tracking the Eth 0/1 link, not 0/0 to achieve the desired affect/ Explanation

A.

HSRP group priority misconfiguration

B.

There is an HSRP authentication misconfiguration

C.

There is an HSRP group number mismatch

D.

This is not an HSRP issue: this is DHCP issue.

E.

The ACL applied to interface is blocking HSRP hello packet exchange

Correct Answer: E

On R1 we see that access list 102 has been applied to the Ethernet 1/0 interface:
Exam 300-135: Question 8 - Image 6

This access list is blocking all traffic to the 224.0.0.102 IP address, which is the multicast address used by HSRP. E

Exam 300-135: Question 9 - Image 1

Examine the configuration on R4. The routing table shows no entries for 172.16.10.0/24 and 172.16.20.0/24. Identify which of the following is the issue preventing route entries being installed on R4 routing table?

A.

HSRP issue between R4 and R2

B.

This is an OSPF issue between R4 and R2

C.

This is a DHCP issue between R4 and R2

D.

The distribute-list configured on R4 is blocking route entries

E.

The ACL configured on R4 is blocking inbound traffic on the interface connected to R2 D

Correct Answer:

If we look at the configuration on R4 we see that there is a distribute list applied to OSPF, which blocks the 172.16.20.0/24 and 172.16.10.0/24 networks.

Exam 300-135: Question 10 - Image 1

You examine the configuration on R5 and discover that no routes are being learned from R4. Which issue prevents the route entries from being installed in the routing table?

A.

HSRP issue between R5 and R4

B.

There is an OSPF issue between R5and R4

C.

There is a DHCP issue between R5 and R4

D.

The distribute-list configured on R5 is blocking route entries

E.

The ACL configured on R5 is blocking traffic for the subnets advertised from R4.
