Project ForgeConsider the following statements: (i) Address Resolution Protocol (ARP) provides a mapping from an IP address to the corresponding hardware (link-layer) address. (ii) A single TCP segment from a sender S to a receiver R cannot carry both data from S to R and acknowledgement for a segment from R to S. Which ONE of the following is CORRECT?
- ABoth (i) and (ii) are TRUE
- (i) is TRUE and (ii) is FALSE
- C(i) is FALSE and (ii) is TRUE
- DBoth (i) and (ii) are FALSE
Explanation
(i) is the standard, correct definition of ARP. (ii) is FALSE — TCP routinely piggybacks an acknowledgement for the reverse direction onto a data-carrying segment in the forward direction; a single segment carrying both is a well-known TCP efficiency feature, not an impossibility.
