Pytanie 52
What are two characteristics shared by TCP and UDP? (Choose two.)
connectionless communication
3-way handshake
port numbering
use of checksum

Pytanie 53
Why are port numbers included in the TCP header of a segment?
to allow the receiving host to assemble the packet in the proper order
to determine which Layer 3 protocol should be used to encapsulate the data
to indicate the correct router interface that should be used to forward a segment
to enable a receiving host to forward the data to the appropriate application
Pytanie 54
Refer to the exhibit. Consider the IP address of 192.168.10.0/24 that has been assigned to a high school building. The largest network in this building has 100 devices. If 192.168.10.0 is the network number for the largest network, what would be the network number for the next largest network, which has 40 devices?
Pytanie 55
Which statement is true about variable-length subnet masking?
Bits are returned, rather than borrowed, to create additional subnets.
The size of each subnet may be different, depending on requirements.
Subnets may only be subnetted one additional time.
Each subnet is the same size.
Pytanie 56
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 destination port numbers are dynamic
when a faster delivery mechanism is needed
when applications do not need to guarantee delivery of the data
when delivery overhead is not an issue
