Question

Consider the following statements:

Which ONE of the following is CORRECT?

• A. Both (i) and (ii) are TRUE
• B. (i) is TRUE and (ii) is FALSE
• C. (i) is FALSE and (ii) is TRUE
• D. Both (i) and (ii) are FALSE

Hint:

ARP is essential for resolving IP addresses to MAC addresses in local networks, while TCP uses piggybacking to acknowledge received segments efficiently.

Answer 1

The Correct Option is B

Statement (i) is TRUE:

• Address Resolution Protocol (ARP) is used to map an IP address (network layer) to a MAC address (link layer). It helps devices communicate in a local network by resolving IP addresses into physical addresses.

Statement (ii) is FALSE:

• TCP uses a mechanism called piggybacking, where a single TCP segment can contain both data and an acknowledgment for data received from the other side.
• This improves efficiency by reducing the number of separate TCP segments needed for communication. However, the statement could be misleading if interpreted as describing the wrong layer or incorrect context for the usage of piggybacking.

Since statement (i) is true and statement (ii) is false, the correct answer is (B).
