Question 1 of 139

A customer network engineer has made configuration changes that have resulted in some loss of connectivity. You have been called in to evaluate a switch network and suggest resolutions to the problems.
Exam 300-135: Question 1 - Image 1

PC2 in VLAN 200 is unable to ping the gateway address 172.16.200.1; identify the issue.

VTP domain name mismatch on SW4

VLAN 200 not configured on SW1

VLAN 200 not configured on SW2

VLAN 200 not configured on SW4

Correct Answer: D

By looking at the configuration for SW2, we see that it is missing VLAN 200, and the "switchport access vlan 200" command is missing under interface eth 0/0:

Question 2 of 139

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 2 - Image 1

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

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

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

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

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

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 3 of 139

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 3 - 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.

There is an HSRP group track command misconfiguration

There is an HSRP group priority misconfiguration

There is an HSRP authentication misconfiguration

There is an HSRP group number mismatch

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:
Exam 300-135: Question 3 - Image 6

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

Question 4 of 139

The following debug messages are noticed for HSRP group 2. But still neither R1 nor R2 has identified one of them as standby router. Identify the reason causing the issue.
Note: only show commands can be used to troubleshoot the ticket.

HSRP group priority misconfiguration

There is an HSRP authentication misconfiguration

There is an HSRP group number mismatch

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

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 4 - 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

Question 5 of 139

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?

HSRP issue between R4 and R2

This is an OSPF issue between R4 and R2

This is a DHCP issue between R4 and R2

The distribute-list configured on R4 is blocking route entries

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.
