Answer 1

Question 16)

The answer is 32.

IPV4 addresses are represented using 32 binary bits.

These are separated into four fields using dotted annotation.

Question 17)

The answer is PoE

When selecting a new switch to support the phones, the primary feature to be considered is PoE.

It is Power over Ethernet.

It is a technology where power is also carried along with the data on the ethernet cables.

These are used for supplying power for devices like access points etc...

Question 18)

The answer is 168.16.1.1

The private address ranges are as shown below.

192.168.0.0 to 192.168.255.255
10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255

These are considered to be private ranges and the others are considered to be public address ranges.

Question 19)

The answer is Physical layer.

The devices like switches which act as bridges are the data link layer devices.

The hubs which are repeaters are the devices present in the physical layer.
