A range of addresses.
It belongs to the Class
B range of addresses.
It belongs to the Class
C range of addresses.

most networks?
Class A
Class B
Class C
Class D
Class
E
8
Refer to the exhibit. Which devices
are recommended to have the IP addresses manually
configured?
PC1 and PC2
all servers
only PC2 Laptop
all hosts and all
servers
9
What is the purpose of a DHCP server on a
network?
to resolve MAC
addresses to IP addresses
to resolve IP addresses
to MAC addresses
to resolve host names
to IP addresses
to assign IP addresses
dynamically to hosts
to assign a MAC address
to a host
10
Refer to the exhibit. What is the
purpose of the Obtain an IP address automatically option shown in the exhibit?
to configure the
computer to use ARP
to configure the
computer to use DHCP
to configure the
computer to use a routing protocol
to configure the
computer with a statically assigned IP
address
11
Why were private IP addresses
developed?
to permit dynamic
assignment of IP addresses
to permit the
duplication of public IP addresses
to minimize the
utilization of reserved IP addresses
to permit public IP
addresses to be used in private networks
to address the issue of
not enough available public IP addresses
12
Why is IP considered a best-effort
protocol?
IP detects lost
packets.
IP validates the
content of the packets.
IP does not provide
acknowledgment of the data delivery.
IP reorders the packet
as they arrive at the destination
host.
13
How many usable hosts are available given
a Class C IP address with the default subnet
mask?
254
255
256
510
511
512
14
What are two facts about how ARP resolves
an IP address to a MAC address? (Choose two.)
The originating host
dynamically issues an arp จCa command to obtain
the destination MAC address.
The originating host
broadcasts an ARP request packet and each host in a
local network receives this packet.
The originating host
dynamically issues an icmp echo request command
to obtain the destination MAC address.
The host with the
specified destination IP address sends an ARP reply
packet containing its MAC address back to the
originating host.
The host with the
specified destination IP address sends an icmp echo
reply packet to the originating host with its MAC
address.
15
Which three addresses are considered to be
private addresses? (Choose three.)
10.45.09.23
15.87.234.87
172.32.45.90
172.17.78.98
192.169.89.56
192.168.45.23
16
Refer to the exhibit. Based on the
information shown, which two statements are true?
(Choose two.)
An ARP request must be
used to obtain an address that is placed in the ARP
table.
Frames from other hosts
in the network to this host will use a destination
address of 00-06-25-25-6e-5d.
The only remote
locations that can be reached from this host are
192.168.1.97 and 192.168.1.254.
If a packet is sent to
a network device other than 192.168.1.97 and
192.168.1.254, an ARP request must be used.
If the computer with
the IP address of 192.168.1.94 sends a packet to the
device with the IP address 192.168.1.97, no ARP request
is required.
17
What is the network broadcast address for
a Class C address of 192.168.32.0 with the default
subnet mask?
192.168.0.0
192.168.0.255
192.168.32.0
192.168.32.254
192.168.32.255
18
Which statement accurately describes
public IP addresses?
Public addresses cannot
be used within a private network.
Public IP addresses
must be unique across the entire Internet.
Public addresses can be
duplicated only within a local network.
Public IP addresses are
only required to be unique within the local
network.
Network administrators
are free to select any public addresses to use for
network devices that access the
Internet.
19
Which subnet mask would be assigned to the
network address of 192.168.32.0 to provide 254 useable
host addresses per subnetwork?
255.255.0.0
255.255.255.0
255.255.254.0
255.255.248.0
20
When a host has an empty ARP cache, what
is the next step the host will take to find the
destination MAC address of a remote host?
sends an ARP request as
a unicast to the server
sends an ARP request as
a unicast to the destination
sends an ARP request as
a broadcast to all hosts in the local network
sends an ARP request as
a unicast to the default gateway
