Q

Which two statements
are correct about an
IPv4 subnet mask?
(Choose two.)

A

*It differentiates the
network portion
from the host
portion of an IPv4
address.

Q

Which three statements
are correct about the
AND operation?
(Choose three.)

A

*The AND operation is
performed between
an IPv4 address and
subnet mask.
*It is used to
determine the
network and host
portions of an IPv4
address.
1 AND 0 results in a 0
