1. How large are IPv4 addresses?
8 bits
16 bits
32 bits
64 bits
128 bits
2. Refer to the graphic. A user at the workstation cannot
connect to the server. All cables have been tested and are working and all
devices have IP addressing. However, the user cannot ping the server. What is
causing the problem?
The router interface
does not have a default gateway.
The switch does not have an IP address and default gateway.
The workstation and server are on different logical
networks.
The workstation does not know the MAC address of the
switch.
3. Refer to the graphic. NAT and DHCP are installed on the
Linksys integrated router. Which IP address is most likely to be assigned to
the local computer, Host1?
10.0.0.17
128.107.1.2
192.135.250.0
209.165.201.1
4. What is one of the benefits of using NAT?
filters network traffic based on IP address ranges
prevents external users from detecting the IP addresses
used on a network
inspects traffic that might be harmful or used in an attack
against the network
translates IP addresses into easy-to-remember domain names
5. Which three statements describe a DHCP Discover message?
(Choose three.)
The source MAC address is 48 ones (FF-FF-FF-FF-FF-FF).
The destination IP address is 255.255.255.255.
The message comes from a server offering an IP address.
The message comes from a client seeking an IP address.
All hosts receive the message, but only a DHCP server
replies.
Only the DHCP server receives the message.
6. Assuming a default mask, which portion of the IP address
175.124.35.4 represents the host?
175.124
35.4
.4
124.35.4
175.124.35
7. Which statement is true concerning private IP addresses?
ensures that two networks separated by the Internet use
unique IP network numbers
allows internal hosts to communicate with servers across
the Internet
solves the issue of a finite number of available public IP
addresses
allows for ISPs to be able to quickly determine network
location
8. What information must be included within a unicast
message for it to be delivered on an Ethernet network?
MAC and IP addresses for the default router
IP address and subnet mask of the default gateway
MAC and IP addresses that correspond to a destination group
MAC and IP addresses that correspond to a specific
destination host
9. What destination IP address is used in a unicast packet?
a specific host
a group of hosts
the default gateway
the network broadcast address
10. Which type of server dynamically assigns an IP address
to a host?
ARP
DHCP
DNS
RARP
11. Which two statements describe packets that are sent
through a Linksys integrated router using NAT? (Choose two.)
Packets that are sent to any destination need to be
translated.
Packets that are sent to hosts on the same network need to
be translated.
Packets that are sent to a destination outside the local
network need to be translated.
Packets that are sent to a destination outside a local
network do not need to be translated.
Packets that are sent between hosts on the same local
network do not need to be translated.
12. A host with the IP address 172.32.65.13 and a default
mask belongs to what network?
172.32.65.0
172.32.65.32
172.32.0.0
172.32.32.0
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 is the destination MAC address in a multicast
Ethernet frame?
the MAC address of the sending host
the MAC address of the destination host
an address that begins with 01-00-5E in hexadecimal
a 48-bit hexadecimal address expressed as FF-FF-FF-FF-FF-FF
15. A PC obtains its IP address from a DHCP server. If the
PC is taken off the network for repair, what happens to the IP address
configuration?
The configuration is permanent and nothing changes.
The address lease is automatically renewed until the PC is
returned.
The address is returned to the pool for reuse when the
lease expires.
The configuration is held by the server to be reissued when
the PC is returned.
16. Refer to the graphic. The host requests an IP
configuration from the Linksys integrated router which is configured to provide
DHCP services. In addition to the host IP address, which additional IP address
is provided that will allow the host to access the ISP and the Internet?
IP address of the destination host
public gateway IP address of the ISP
external IP address of the integrated router that connects
to the ISP
internal IP address of the integrated router that connects
to the local network
17. Yvonne is talking to her friend on the phone. What type
of message is this?
broadcast
simulcast
multicast
unicast
18. Which default subnet mask provides the most host bits?
255.0.0.0
255.255.0.0
255.255.255.0
255.255.255.252
19. Which part of an IP address identifies a specific
device on a network?
first two octets
third and fourth octets
network portion
host portion
only the fourth octet
20. How many bits are available for Class B host IP
addresses using a default subnet mask?
4
8
