What is the default number of pings issued by a DHCP
server to a pool address before sending the DHCPOFFER to a
client?
one
two
three
four
five
3
What is the purpose of the DHCPDECLINE
message?
If the DHCP client received
multiple DHCPOFFERs, it uses the DHCPDECLINE to refuse the offers it
does not use.
If the DHCP server sends an IP
configuration update that the DHCP client does not need, it uses the
DHCPDECLINE to refuse the information.
The DHCP server uses the
DHCPDECLINE message to refuse a DHCP client's request for IP
configuration information.
If the DHCP client detects that the
address supplied by the DHCP server is in use on the network, it
uses the DHCPDECLINE to refuse the
offer.

dynamic allocation process of DHCP? (Choose three.)
Gateway address
DNS server
DHCP Server
Subnet mask
Key server
ARP
server

arrow shown in the partial configuration output of a Cisco 806

into the router
defines which addresses can be
translated
defines which addresses are
assigned to a NAT pool
6

router, what kind of address is 10.10.10.3 with the IP
identification number of 29855?
inside local
inside global
outside local
outside
global
7
Given the accompanying graphic, which statement would
be applied to the S0 interface when configuring NAT on the Tampa
router?
ip nat inside
ip nat outside
ip pat inside
ip pat
outside
8
Given the accompanying graphic, which addresses could
be assigned to traffic leaving S0 as a result of the statement ip
nat pool Tampa 179.9.8.96 179.9.8.111 netmask 255.255.255.240?
(Choose two.)
10.0.0.125
179.9.8.95
179.9.8.98
179.9.8.101
179.9.8.112
9
Refer to the exhibit. Which command would establish a
group of 30 IP addresses that could be used to hide inside addresses
from the Internet?
ip nat pool Raleigh 10.0.0.32
10.0.0.63 netmask 255.255.255.224
ip nat pool Raleigh 10.0.0.32
10.0.0.63 netmask 255.255.255.240
ip nat pool Raleigh 171.11.10.32
171.11.10.63 netmask 255.255.255.224
ip nat pool Raleigh 171.11.10.32
171.11.10.63 netmask
255.255.255.240
10
Given the accompanying diagram, which commands are
necessary to implement PAT on the Raleigh router? (Choose
four.)
access-list 10 permit
192.168.10.0 0.0.0.255
access-list 10 permit 171.11.0.0
0.0.255.255
ip nat inside source static
192.168.10.1 171.11.0.0
ip nat inside source list 10
interface S0 overload
ip nat outside
ip nat
inside
11
What is true regarding the differences between NAT and
PAT?
PAT uses the word "overload" at the
end of the access-list statement to share a single registered
address.
Static NAT allows an unregistered
address to map to multiple registered addresses.
Dynamic NAT allows hosts to receive
the same global address each time external access is required.
PAT uses unique source port numbers
to distinguish between
translations.
12
Which of the following are broadcasts sent by a client
to a DHCP server? (Choose two.)
DHCPDISCOVER
DHCPRELEASE
DHCPACK
DHCPREQUEST
DHCPOFFER
13
In addition to assigning addresses from predefined
pools, which other services can a DHCP server offer? (Choose
three.)
DNS server addresses
domain names
global IP assignments
NAT translations
WINS server
addresses
14
Users are complaining that they cannot attach to
network resources. A technician has confirmed that clients are not
properly receiving IP configuration information through the DHCP
process. The network administrator wants to watch the DHCP process
while the technician tries to release and renew addresses on the
clients. Which command would the network administrator use to
monitor the process of address allocation?
show ip dhcp server
statistics
show ip dhcp binding
debug ip dhcp server
events
debug ip dhcp
binding
15
Refer to the graphic. Which command would allow the
router to forward DHCP broadcasts from Host A to the DHCP
server?
ip helper-address
dhcp helper-address
dhcp relay-agent
dhcp-relay
16
What is the default lease time for addresses assigned
to clients through Easy IP?
twenty-four hours
forty-eight hours
one week
two
weeks
17
The Raleigh router shown in the diagram is configured
with PAT. Which of the following must be changed if the private
network is migrated to a 10.0.0.0 network? (Choose two.)
E0 interface address
S0 interface address
the access-list statement
the NAT outside interface
the NAT inside
interface
18
A network administrator needs to configure a router to
offer DHCP services. Assuming the router is operating with factory
defaults and the IOS supports DHCP, what must be done to start the
DHCP service?
Use the global configuration
command service dhcp.
Use the privileged command service dhcp start.
Use the start service dhcp command during the setup processes.
Do nothing. The DHCP service is
enabled by default during start up.

A company was issued 207.48.12.8/29 as its registered
address from its ISP. Which of the following is a solution that will
allow Internet access to 300 employees simultaneously?
VLSM to further subnet the
registered address and create more IP addresses
normal subnetting on the Class C
network and address the host
RFC 1918 and port address
translation
this is an impossible scenario
because there are not enough
addresses
