Four sample networking interview questions with example responses
To better prepare for your network administration interview, here are four sample questions with example answers:
1. What are the essential skills required to be a successful network administrator?
The hiring manager asks this question to evaluate your understanding of the job description and the required skills and abilities. They are also assessing your strengths as a candidate based on the skills you choose. When responding to the question, focus on skills the company listed explicitly within the job posting that you can deliver in the position.
Example: "A successful network administrator's top three skills are problem solving, organization, and attention to detail. Because network administrators need to identify network problems and develop fast and effective solutions, experienced problem-solving skills are a must. In addition, they need to be organized and keep track of projects, issues, and other critical information. Organization also helps when things go wrong by finding data quickly. And a network administrator needs to pay attention to the details. There are so many little details that can wreak havoc on a network; it's critical to stay focused and accurate."
2. What are some strengths that help you when troubleshooting network issues?
The recruiter or hiring manager asks this question to evaluate your ability to handle network challenges and what skills you use to solve the problem. They are also assessing your process for troubleshooting. You can include a real-world example to describe your skills in action if you have a specific example to share. Otherwise, stick with essential skills for problem-solving and your evaluation process.
Example: "When troubleshooting a network issue, I use several strengths that I've developed with experience. For example, in my previous position, the company's network went down one evening because of a power failure. Unfortunately, I couldn't get the system up, so I needed to assess the situation. First, I noted all possible issues and then prioritized them based on the likelihood of occurrence. Next, I analyzed the issues using critical thinking and logical and deductive reasoning. I patiently reviewed each idea to cross them out, and I finally found the problem. Then I could quickly get the system back online."
3. What is an intrusion detection system?
A hiring manager will ask this technical question to evaluate your specialized expertise in network security. Understanding what an intrusion detection system is and its importance to a company's data confidentiality will allow you to show your expertise in security matters with networking. Your response can include any first-hand experience you have using such a system.
Example: "An intrusion detection system, also called an IDS, is like an antivirus program for the network. It monitors network traffic and looks for suspicious activity, policy violations, or vulnerable areas. If it detects any anomaly, it sends an alert for the anomaly to be investigated. Although just a monitoring program, an intrusion detection system is important to the integrity of a network's security defences."
4. What form of authentication can someone use to access the network?
A recruiter or hiring manager asks this question to evaluate your expertise in network access protocol. There are several forms of authentication a network administrator can use. So it's recommended to focus on options that increase the level of security in your response.
Example: "There are several forms of authentication someone can use to access a network, depending on the company's requirements and security protocol. For example, authentication factors include email verification, passwords, tokens, security questions, personal identification numbers or PINs, and biometric scans. I recommend using a minimum of two-factor authentication when setting up network access protocols."
