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.
- Private IPv4 addresses are
assigned to devices within an
organization’s intranet (internal
network). - Any organization (home, school,
office, company) can use the
10.0.0.0/8 address.
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.
- To access a device over the
internet, the destination IPv4
address must be a public address. - Public IPv4 address exhaustion is a
reason why there are private IPv4
addresses and why organizations
are transitioning to IPv6.

organizations receives IP addresses
from IANA and is responsible for
allocating these addresses to ISPs and
some organizations?

* IEEE
* RIRs
* Tier 1 ISPs
- RIRs
Which devices will not forward an IPv4
broadcast packet by default?
* Ethernet switch
* router
* Windows PC
* None of the above. All devices
forward IPv4 broadcast packets by
default
- router
.Which two situations are the result of
excessive broadcast traffic? (Choose
two)
* slow network operations
* slow device operations
* when devices on all adjacent
networks are affected
* when the router has to forward an
excessive number of packets
- slow network operations
- slow device operations
What does the IP address
172.17.4.250/24 represent?
* network address
* multicast address

how many IP addresses are available
for hosts on this network?
* 256
* 254

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
- to determine the subnet to which
the host belongs
A network administrator is variably

.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
- The size of each subnet may be
different, depending on
requirements.
.Why does a Layer 3 device perform
the ANDing process on a destination
IP address and subnet mask?
* to identify the broadcast address
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
- to identify the network address of
the destination network
