Question

in what two situations would udp be better than tcp as the preferred transport protocol? (choose two.) when destination port numbers are dynamic when delivery overhead is not an issue when applications need to guarantee that a packet arrives intact, in sequence, and unduplicated when a faster delivery mechanism is needed when applications do not need to guarantee delivery of the data

Explanation:

• UDP is connectionless and has lower overhead than TCP. So, when delivery overhead is not a major concern (as UDP's simple nature can be utilized), it can be a choice.
• UDP does not guarantee delivery (unlike TCP which has mechanisms for reliable delivery like acknowledgments). When applications do not need guaranteed delivery (e.g., in some streaming scenarios where a few lost packets are tolerable), UDP can be better.
• TCP is used when packet integrity, sequence, and no - duplication are required (so that option is for TCP). Destination port numbers being dynamic is not a key differentiator between UDP and TCP in terms of preference. And while UDP can be faster in some ways (less overhead for connection - related tasks), the more fundamental aspect compared to TCP is the lack of guaranteed delivery.

Answer:

when delivery overhead is not an issue, when applications do not need to guarantee delivery of the data
