Here's how you can assess your colleague's grasp of network protocols in computer networking.

2 Practical Tasks

Assign practical tasks that require your colleague to configure network settings or troubleshoot network issues. For example, setting up a DHCP (Dynamic Host Configuration Protocol) server or diagnosing problems with DNS (Domain Name System) resolution. Through these tasks, you can observe their approach to solving real-world networking problems and their ability to apply theoretical knowledge of protocols in practice. The quality and efficiency of their work will speak volumes about their proficiency.

3 Discuss Concepts

Engage in discussions about advanced networking concepts like subnetting or the intricacies of the OSI (Open Systems Interconnection) model, which structures network communication into seven layers. See if they can articulate how different protocols interact within these layers, such as how FTP operates at the application layer while Ethernet functions at the data link layer. Their ability to discuss these concepts comfortably will indicate a deeper understanding of network protocols.

4 Review Documentation

Request that your colleague creates or reviews network documentation that outlines the protocols in use within your organization's network. This includes network diagrams, IP addressing schemes, and configuration files. By examining how they document or critique existing documentation, you can assess their attention to detail and their grasp of protocol specifics and network design principles.

5 Scenario Simulation

Create a simulation or a lab environment where your colleague can demonstrate their knowledge by setting up a network from scratch or by integrating new protocols into an existing network. For instance, they could configure a VLAN (Virtual Local Area Network) or implement IPsec (Internet Protocol Security) for secure VPN (Virtual Private Network) connections. How they handle these simulations will show their practical skills and problem-solving abilities.

6 Peer Feedback

Finally, consider soliciting feedback from other team members who have worked with your colleague on networking tasks. They can provide insights into how your colleague handles protocol-related issues and whether they follow best practices. Peer feedback can often reveal aspects of your colleague's understanding and performance that you might not see in a one-on-one assessment.
