Explanation / Answer

Text to copy:

1.

The address allocation mechanisms of DHCP are

Automatic Allocation: The IP address is allocated to the device permanently by the server. The address is selected from the pool of available addresses.

Dynamic Allocation: The IP address is allocated to the device for a specific period of time by the server. The server allows the client to retain the address for a limited period of time or client tells the server that it no longer require the address.

Manual Allocation: An IP address is pre-allocated to a single client by the administrator and it is communicated to the client by the server.

Therefore a, b and d are correct.

2.

The types of packets used by the TFTP are write request, acknowledgement and data and are represented by WRQ, QCK, and DATA respectively.

Therefore b, c and d are correct.

3.

Trivial File Transfer Protocol (TFTP) is file transfer protocol which uses lock-step delivery approach.

Therefore ‘a’ is correct.

4.

The WINS and DNS services are used resolve the names for the NetBIOS name space and DNS domain names respectively.

Therefore ‘a’ and ‘d’ are correct.

5.

DHCP network allocation mechanism - Dynamic Allocation: The IP address is allocated to the device for a specific period of time by the server. The server allows the client to retain the address for a limited period of time or client tells the server that it no longer require the address.

Therefore ‘b’ is correct.

6.

Hypertext Transfer Protocol (HTTP): It is a stateless protocol. So, the server using HTTP will not retain the session information or status about each communication partner for the duration of multiple requests.

Therefore ‘b’ is correct.
