Without this private net, our business would have been susceptible to security threats. ”

When something went faulty with our net at my stopping point job, I needed to be able to figure out what it was and implement a solution cursorily. They should besides enjoy learning new things. As technology is always changing, you want a network administrator who is keeping up to go steady on not lone the latest innovations but the newest threats adenine well. That ‘s why I read the latest technical school journals vitamin a frequently as I can and attend conferences each year. Lastly, network administrators should have strong communication skills, so that they can efficaciously work with everyone else involved on the team and let them know what ‘s going on with the network. ”

At my former job, I was assigned the task of picking out equipment for our office.

To remedy this, I transitioned the network into a Domain apparatus. A Domain setup allowed me to monitor access and security permissions in all of the other computers. This centralize system made it easier to secure and more effective. ”

5. Do you have any experience with proxy servers? If so, how did you protect them?

proxy servers are another way businesses can protect themselves on-line. A commodity network administrator will know where and when to use them, along with how to protect them. exercise : “ At my former position of use, we used proxy servers to prevent undesirable users from gaining access to our net. To protect it, we limited the number of proxy servers, controlled where the proxy service could be accessed from and shut it off when we were n’t using it. It was besides my responsibility to regularly check the proxy waiter logs and attend for issues. ”

6. Explain when you would use straight cables and cross cables.

There, the company had all sorts of computers, routers and hubs that needed to be connected together. I used the cross cables when connecting computers to other computers, or hubs to other hub. The straight cables were for when I needed to connect a calculator to a hub, router, trade or modem. There were a bunch of wires lying around, but I finally got it all arranged correctly. ”
