This question allows you to describe your past network administration experience. You can describe what you did to prepare for this position to entry-level candidates or those with different professional experiences.

Otherwise, you might discuss the primary aspects that motivated you to apply for this position that you learned from your prior network administrator employment.

As an example: "At my previous position, I got substantial expertise in both workgroups and domains. Understanding all of these sorts of network management has positioned me for any type of network management, and I am familiar with both the server-to-client configuration and the respective system level."

2. What was your most difficult network administration experience?

Your response to this question demonstrates how you overcome a workplace challenge.

Choose one or more difficulties from your prior network administrator employment and use the STAR response approach to explain the scenario you encountered, the task you needed to complete, the action you did, and the outcome that happened.

Instance: "Once upon a time, an outside source attempted to phish our network. I was working with our network management department's security staff, and some of our employees were handling different procedures than the rest of us. I gathered the crew and outlined the proper process to follow, and we controlled the security of our network properly".

3. Do you have any network administration qualifications or training?

Network administration certificates include CompTIA Network+, CompTIA Security+, CompTIA A+, Cisco CCNA, Cisco CCNP, Microsoft Certified Solutions Associate, and Microsoft Certified Solutions Expert.

Having one or more of these certifications might demonstrate to the interviewer your knowledge and ability in a wide range of network administration tasks.

Consider mentioning your certificates and explaining how you use them on the job in your response. If you lack certification, you can explain your training or experience in the network administration profession, as well as declare your intention in getting certification in the future.

For instance: "I now hold the Microsoft Certified Solution provider Associate certification and intend to pursue the Microsoft Certified Solutions Expert certification. My past jobs offered training that qualified me for these certification training as well as the network management responsibilities that I've done."

4. How do you distinguish between local, global, and universal groups?

Studying network management terminologies and protocols before your interview might help you demonstrate to the interviewer that you comprehend what you need to know for the role.

Aside from your basic understanding, your response might reveal how well you understand the distinction between switches and hubs.

As an example: "On the outside, switches and hubs seem similar and are used to build a network. The most visible distinction is how each handles interconnections.

7. What kinds of authentication are available for network access?

Your response to this question helps the interviewer assess your understanding of network access and the many authentication options available.

The most crucial aspect of your response may be the requirement for two-factor authentication for greater security.

When three-factor authentication is required, enhanced security networks can employ it."

8. What monitoring methods and tools do you prefer?

This question may be asked by an interviewer to allow you to discuss your past job experience in network management.

Answer this question by demonstrating what tools and techniques you appreciate and what you may use in your possible employment.
