Question 6

Which protocol is used to resolve domain names into IP addresses?

Accepted Answer

DNS

Answer

HTTP

Answer

HTTPS

Answer

UDP

Question 7

How do synchronous protocols differ from asynchronous protocols?

Accepted Answer

Synchronous protocols require both parties to be ready before data transfer, while asynchronous protocols allow independent data transmission.

Answer

Synchronous protocols are inherently faster than asynchronous protocols.

Answer

Asynchronous protocols are generally more reliable than synchronous protocols.

Answer

Synchronous protocols are only used for local communication, whereas asynchronous protocols are suitable for long-distance communication.

Question 8

Which layer of the OSI model is responsible for routing packets between networks?

Accepted Answer

Network layer

Question 11

Which protocol is primarily used for transferring files across a network?

Accepted Answer

FTP

Answer

HTTP

Answer

SMTP

Answer

DNS

Question 12

What is the key distinction between connection-oriented and connectionless protocols?

Accepted Answer

Connection-oriented protocols establish a dedicated communication channel, while connectionless protocols do not.

Answer

Connectionless protocols are more reliable than connection-oriented protocols.

Answer

Connection-oriented protocols are used for real-time applications, while connectionless protocols are used for non-real-time applications.

Answer

There is no difference between connection-oriented and connectionless protocols.
