Network Administrator interview questions shared by candidates
There are two directly-connected switches. Assume that they communicate fine on the physical layer. Why can't two hosts with assigned addresses 192.168.100.5/30 and 192.168.100.50/30 communicate with each other? Also assume that network addresses can be used. How would you remedy this by swapping out only ONE of the devices on the network?

The hosts are on two different subnets. Replace one of the switches with a properly-configured router. Less

the host which assign 192.168.100.5/30 and host 192.168.100.50/30 these subnet is not belong to same subnet Less

The subnet being used only provides 2 useable address, .5 and .6 the .50 address is out of the range. If there are only switches and no router, swap out one switch with a router and re-configure the network addresses. Less

What is a switch and what is a router.
2 Answers↳
Router create broadcast domains by breaking multiple network into broadcast domain. Router is a layer 3 device and it is used in forwarding packet to the next hop(or next destination). Switch is a layer 2 device that creates collision domains. By creating collision domains, data performance is improved as there is no contention(as seen in CSMA/CD in hubs) as each port has its own dedicated bandwidth. Less

a switch is a computer networking device that connects devices together on a computer network, by using packet switching to receive, process and forward data to the destination device. Router routes data to different networks or between networks. Less
You have four situations - who do you help first: 1) The CEO who can't get into his e-mail 2) An unpleasant employee who cannot login to their computer 3) Your friend who can't print a document 4) An internet router that is down No further information will be given.

1st - The router so multiple employees can use the resource 2nd - The unpleasant employee - because they usually are the ones tasked with the most work and may be a key employee, plus they cant do anything on their computer 3rd - The CEO, because you don't want to keep him waiting Then #4 your friend, because he would be able to understand and can use other resources (such as e-mail to a co-worker) in the meantime.

This is a typical root cause corrective action question. The router is the culprit here of all the other issues, or at least could be. The CEO probably can't access his email due to no connectivity, as well as the employee not being able to log on and your friend not being able to print. Less
