Pytanie 49

How many hosts are addressable on a network that has a mask of 255.255.255.248?

Pytanie 50

Which subnet would include the address 192.168.1.96 as a usable host address?

192.168.1.32/28

192.168.1.64/26

192.168.1.32/27

Pytanie 51

What subnet mask is needed if an IPv4 network has 40 devices that need IP addresses and address space is not to be wasted?

255.255.255.192

255.255.255.0

255.255.255.128

Pytanie 52

What are two characteristics shared by TCP and UDP? (Choose two.)

connectionless communication

port numbering

3-way handshake

default window size

ability to to carry digitized voice

use of checksum

Pytanie 53

Why are port numbers included in the TCP header of a segment?

to enable a receiving host to forward the data to the appropriate application

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 allow the receiving host to assemble the packet in the proper order

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?

Subnets may only be subnetted one additional time.

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

Each subnet is the same size.

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

Pytanie 56

In what two situations would UDP be the preferred transport protocol over TCP? (Choose two.)

when delivery overhead is not an issue

when destination port numbers are dynamic

when applications need to guarantee that a packet arrives intact, in sequence, and unduplicated

when applications do not need to guarantee delivery of the data
