Question 2: How do you configure a router for EIGRP?
Configuring a router for EIGRP (Enhanced Interior Gateway Routing Protocol) involves several steps to enable EIGRP and specify the networks that should be advertised and participate in the EIGRP routing process. Here’s a basic outline of the steps to configure a router for EIGRP:
1. Access Router Configuration Mode:
– Access the router’s configuration mode using a terminal or console connection. Enter privileged EXEC mode by typing `enable` and then enter global configuration mode by typing `configure terminal` or `conf t`.
2. Enable EIGRP on the Router:
– To enable EIGRP, use the following command:
“`
router eigrp AS_NUMBER
“`
Replace `AS_NUMBER` with the Autonomous System number you want to use for EIGRP. This number is used to identify the EIGRP domain and must match on all routers within the same EIGRP network.
3. Specify Networks to Advertise:
– Use the following command to specify the networks that should be advertised by EIGRP:
“`
network NETWORK_ADDRESS NETWORK_MASK
“`
Replace `NETWORK_ADDRESS` with the IP address of the network you want to advertise, and `NETWORK_MASK` with the subnet mask of the network. Repeat this command for each network you want to include in EIGRP.
4. Adjust EIGRP Metrics (Optional):
– By default, EIGRP uses bandwidth and delay as metrics for path selection. If you want to adjust the default metrics or use other metrics, you can use the `metric` command under the router EIGRP configuration mode.
5. Adjust Hello and Hold Timer (Optional):
– EIGRP uses hello and hold timers to establish and maintain neighbor relationships. The default hello timer is 5 seconds, and the hold timer is 15 seconds. You can adjust these timers using the following commands:
“`
timers eigrp HELLO_INTERVAL HOLD_TIME
“`
Replace `HELLO_INTERVAL` with the desired hello timer value (in seconds) and `HOLD_TIME` with the desired hold timer value (in seconds).
6. Verify Configuration:
– After configuring EIGRP, use the `show ip eigrp interfaces` and `show ip eigrp neighbors` commands to verify that the router is forming EIGRP neighbor relationships and advertising the correct networks.
7. Save Configuration:
– Save the configuration changes to the router’s startup configuration so that they persist across reboots. Use the `write memory` or `copy running-config startup-config` command to save the configuration.
Remember that EIGRP should be configured consistently on all routers within the same Autonomous System (AS) for proper operation. Additionally, EIGRP is a Cisco proprietary protocol, so it is typically used in Cisco networking environments. If you have a multi-vendor network, consider using a standard routing protocol like OSPF (Open Shortest Path First) instead. This is the answer to question 2 of CCNA 200-301 sample questions set 59.

Question 5: What is the purpose of a proxy server and how does it work?
The purpose of a proxy server is to act as an intermediary between a client device (such as a computer or smartphone) and other servers on the internet. It serves several functions and provides various benefits for users and network administrators. A proxy server works by receiving requests from clients and forwarding them to the appropriate servers, and then relaying the responses back to the clients.
Here’s how a proxy server works and its main purposes:
1. Anonymity and Privacy:
– One of the main purposes of a proxy server is to provide anonymity for users. When a client requests a resource from the internet through a proxy, the request appears to come from the proxy server, not the client’s device. This helps hide the client’s real IP address and location from the destination server, enhancing privacy.
2. Content Filtering and Access Control:
– Proxy servers can be configured to filter web content and block access to specific websites based on predefined rules. This makes them valuable tools for enforcing internet usage policies in organizations and schools.
3. Caching and Content Acceleration:
– Proxy servers can cache frequently requested web pages, images, and other content locally. When another client requests the same content, the proxy can serve it from the cache instead of fetching it from the original server. This reduces bandwidth usage and speeds up content delivery.
4. Bandwidth Control and Traffic Shaping:
– Proxy servers allow administrators to control and limit bandwidth usage for specific clients or applications. This helps in managing network resources efficiently and ensuring fair access for all users.
5. Firewall and Security:
– Proxy servers act as an additional layer of security by acting as a buffer between clients and the internet. They can inspect and filter incoming and outgoing traffic, protecting the internal network from malicious content or potentially harmful requests.
6. Load Balancing:
– Proxy servers can distribute incoming client requests among multiple servers, balancing the load and preventing any single server from being overwhelmed with traffic. This helps optimize server performance and ensures high availability.
7. Accessing Restricted Content:
– Proxy servers can be used to bypass internet censorship and access content that might be restricted in certain regions or networks.
8. Authentication and User Identification:
– Proxy servers can require users to authenticate before granting access to the internet. This helps in tracking user activity and enforcing user-based access controls.
In summary, a proxy server serves as an intermediary between clients and the internet, providing several benefits, including enhanced privacy, content filtering, caching, security, and traffic management. It plays a crucial role in optimizing network performance, protecting users and networks from potential threats, and enabling controlled and secure internet access. This is the answer to question 5 of CCNA 200-301 sample questions set 59.
