Q

Which two statements are correct
about private IPv4 addresses?
(Choose two.)
* Private IPv4 addresses are
assigned to devices within an
organization’s intranet (internal
network).
* Internet routers will typically
forward any packet with a
destination address that is a
private IPv4 address.
* 172.99.1.1 is a private IPv4
address.
* Any organization (home, school,
office, company) can use the
10.0.0.0/8 address.

A
  • Private IPv4 addresses are
    assigned to devices within an
    organization’s intranet (internal
    network).
  • Any organization (home, school,

Q

Which two statements are correct
about public IPv4 addresses? (Choose
two.)
* Public IPv4 addresses are allowed
to be assigned to devices within an
organization’s intranet (internal
network).
* To access a device over the
internet, the destination IPv4
address must be a public address.
* 192.168.1.10 is a public IPv4
address.
* Public IPv4 address exhaustion is a
reason why there are private IPv4
addresses and why organizations
are transitioning to IPv6.

Q

What is the purpose of the subnet
mask in conjunction with an IP
address?
* to uniquely identify a host on a
network
* to identify whether the address is
public or private
* to determine the subnet to which
the host belongs
* to mask the IP address to
outsiders

A
  • to determine the subnet to which
    the host belongs

Q

.Which statement is true about
variable-length subnet masking?
* 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

A
  • The size of each subnet may be
    different, depending on
    requirements.
17
Q

.Why does a Layer 3 device perform
the ANDing process on a destination
IP address and subnet mask?

of the destination network
* to identify the host address of the
destination host
* to identify faulty frames
* to identify the network address of
the destination network

A
  • to identify the network address of
    the destination network
