[ramesh]

You are the computer technician for your company. An employee complains that they cannot access resources on the company's network or the Internet. No other users have reported any problems. Upon inspection, you find that the user's computer has an IP address of 192.168.1.54 and a Subnet Mask of 255.255.255.192, but no default gateway. What should you input for the computer's default gateway? Choose the best option(s) from those listed below.

a) 192.168.1.255
b) 192.168.1.0
c) 192.168.1.54
d) 192.168.1.1

[Skele Drew]

Not sure how to do the calculations, so I'll use my own gateway though the mask is different.

[zRo ToLeRaNcE]

The question should have been made more difficult by saying that the persons IP was 192.168.1.76. This one too easy.

[ramesh]

Of the options provided, only 192.168.1.1 is a valid host address that could be used for the default gateway. As well, default gateways are generally the first available IP address on a subnet. It is rare that you will see a network where the default gateway is configured as an address other than the first available.

Correct Option(s):

d) 192.168.1.1

Incorrect Option(s):

a) 192.168.1.255 - This would be the broadcast address for the 192.168.1.0 network. Broadcast addresses cannot be assigned.
b) 192.168.1.0 - This would be the network address for the 192.168.1.0 network. Network addresses cannot be assigned.
c) 192.168.1.54 - This is the IP address for the user's computer. An IP address cannot be used on the same network twice.
