Explanation / Answer

Dear Student,

The correct answer is:

Option: A     The computer does not have a DNS entry.

-----------------------------------------------------------------------------------------------------------------------------------------

Reason: The IP address 192.168.10.1 does not exist in the router configuration. While the    default gateway is 192.168.10.62. And in the configuration IP range is starting from 192.168.10.62 to 255.255.255.224.

Hence the computer does not have a DNS entry.

--------------------------------------------------------------------------------------------------------------------------------------

what is DNS.?

DNS stand for Domain Name Server. "DNS" refers to the way that your computer tries to look up the name of a server to find its numeric IP address so it can connect to the server. It's similar to looking a phone number up in a telephone book when you want to call someone on the phone.
