In what two situations would UDP be the preferred transport protocol over TCP? (Choose two.)
- when applications need to guarantee that a packet arrives intact, in sequence, and unduplicated
- when a faster delivery mechanism is needed
- when delivery overhead is not an issue
- when applications do not need to guarantee delivery of the data
- when destination port numbers are dynamic
Explanation: UDP is a stateless protocol, which means that neither device on either end of the conversation must keep track of the conversation. As a stateless protocol, UDP is used as the Layer 4 protocol for applications that need speedy (best-effort) delivery. An example of such traffic is the transport of digitized voice or video.
