Network Administrator Interview Questions

Sample answer to the question

One time, I was tasked with making recommendations on server system administration. I approached it by first conducting an in-depth analysis of the current server infrastructure and identifying any pain points or areas for improvement. I then researched industry best practices and emerging technologies to find solutions that could address the identified issues. After evaluating various options, I prepared a detailed report outlining my recommendations, including the advantages and disadvantages of each option. I also considered factors such as cost, scalability, and security. Finally, I presented my recommendations to the relevant stakeholders, explaining the rationale behind each choice and highlighting the potential impact on the organization.

A more solid answer

In my previous role, I had to make recommendations on server system administration when the company experienced frequent network outages. To approach this, I first conducted a thorough network assessment, examining firewall configurations, network traffic patterns, and server logs. I also reviewed the existing security practices and anti-virus programs in place. Through my research, I discovered that the outdated firewall firmware and lack of regular patching were major contributors to the outages. To address these issues, I recommended upgrading the firewall firmware and implementing a patch management system. I prepared a cost analysis, highlighting the benefits of these recommendations in terms of network stability and security. I presented my findings to the IT team and management, explaining the potential impact and seeking their input. Ultimately, my recommendations were approved, and the implemented changes significantly reduced network outages.
