300-135 Exam Questions and Answers

To help you prepare for the 300-135 exam, let’s take a closer look at some of the types of questions you may encounter, along with sample answers.

Sample Question 1: Troubleshooting OSPF

Question: You are troubleshooting an OSPF network and notice that two routers are not forming an adjacency. What could be the possible causes, and how would you resolve them?

Answer: There are several potential reasons why OSPF routers may not form an adjacency:

1. Mismatched OSPF Area IDs: Ensure that both routers are configured with the same OSPF area ID.

2. Mismatched Network Types: Verify that the OSPF network type (e.g., broadcast, point-to-point) is consistent on both routers.

3. Incorrect Subnet Masks: Check that the subnet masks on the interfaces participating in OSPF are correctly configured.

4. Authentication Issues: If OSPF authentication is enabled, ensure that both routers are using the same authentication method and password.

5. MTU Mismatch: Verify that the Maximum Transmission Unit (MTU) size is the same on both routers.

To resolve the issue, you would need to systematically check each of these potential causes and make the necessary adjustments to the router configurations.

Sample Question 2: Troubleshooting VLANs

Question: You are troubleshooting a network where devices in the same VLAN are unable to communicate with each other. What could be the problem, and how would you fix it?

Answer: The issue could be related to several factors:

1. VLAN Configuration: Ensure that the VLAN is correctly configured on all switches and that the devices are assigned to the correct VLAN.

2. Trunking Issues: Verify that trunk ports are correctly configured and that the VLAN is allowed on the trunk.

3. Spanning Tree Protocol (STP): Check if STP is blocking a port, preventing communication between devices.

4. Layer 3 Issues: If inter-VLAN routing is required, ensure that the Layer 3 device (e.g., a router or Layer 3 switch) is correctly configured.

To resolve the issue, you would need to check the VLAN configuration on the switches, verify trunking settings, and ensure that STP is not blocking any necessary ports.

Sample Question 3: Troubleshooting IPsec VPN

Question: You are troubleshooting an IPsec VPN tunnel that is not establishing. What could be the possible causes, and how would you resolve them?

Answer: The issue could be related to several factors:

1. Mismatched Pre-Shared Keys (PSK): Ensure that both ends of the VPN tunnel are using the same PSK.

2. Incorrect IP Addresses: Verify that the IP addresses configured for the VPN tunnel are correct.

3. Mismatched Encryption and Authentication Algorithms: Ensure that both ends of the VPN tunnel are using the same encryption and authentication algorithms.

4. NAT Traversal (NAT-T) Issues: If NAT is involved, ensure that NAT-T is enabled on both ends of the VPN tunnel.

5. Firewall Rules: Check that any firewalls between the VPN endpoints are allowing the necessary traffic.

To resolve the issue, you would need to verify the configuration on both ends of the VPN tunnel, check for any mismatched settings, and ensure that firewalls are not blocking the VPN traffic.
