Each subnet is the same size.

The size of each subnet may be different, depending on requirements.

Subnets may only be subnetted one additional time.

Bits are returned, rather than borrowed, to create additional subnets.

Question 15

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
