Sample 200-125 Exam Questions and Answers
To help you prepare for the 200-125 exam, here are some sample questions and answers:
Question 1: What is the purpose of a VLAN?
Answer: A VLAN (Virtual Local Area Network) is used to segment a network into smaller, more manageable sections. VLANs improve network performance by reducing the size of broadcast domains and enhance security by isolating traffic between different groups of users.
Question 2: How do you configure a static route on a Cisco router?
Answer: To configure a static route on a Cisco router, use the following command:
Router(config)# ip route [destination network] [subnet mask] [next-hop address or exit interface]
For example, to route traffic to the 192.168.1.0 network with a subnet mask of 255.255.255.0 through the next-hop address 10.0.0.1, you would use:
Router(config)# ip route 192.168.1.0 255.255.255.0 10.0.0.1
Question 3: What is the difference between OSPF and EIGRP?
Answer: OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol) are both routing protocols, but they have some key differences:
OSPF is a link-state routing protocol that uses the Dijkstra algorithm to calculate the shortest path to a destination. It is an open standard and is widely used in large enterprise networks.
EIGRP is a Cisco-proprietary routing protocol that uses a hybrid approach, combining features of both distance-vector and link-state protocols. It is known for its fast convergence and efficient use of bandwidth.
Question 4: How do you troubleshoot a network connectivity issue?
Answer: Troubleshooting a network connectivity issue involves several steps:
- Check Physical Connections: Ensure that all cables are securely connected and that there are no physical issues with the network devices.
- Verify IP Configuration: Use the ipconfig (Windows) or ifconfig (Linux) command to check the IP address, subnet mask, and default gateway.
- Ping the Default Gateway: Use the ping command to test connectivity to the default gateway.
- Check Routing Tables: Use the show ip route command on a router to verify that the correct routes are in place.
- Test DNS Resolution: Use the nslookup command to verify that DNS is functioning correctly.Check for ACLs: Verify that there are no access control lists (ACLs) blocking traffic.
Question 5: What is the purpose of an ACL?
Answer: An ACL (Access Control List) is used to control traffic flow in and out of a network. ACLs can be used to permit or deny traffic based on various criteria, such as source IP address, destination IP address, and protocol type. ACLs are commonly used to enhance network security by restricting access to certain resources.
