Question:
In what two situations would UDP be better than TCP as the preferred transport protocol? (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 very simple transport layer protocol that does not guarantee delivery. Devices on both ends of the conversation are not required to keep track of the conversation. UDP is used as the transport protocol for applications that need a speedy, best-effort delivery.
