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
6
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
7
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
8
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
9
What is the purpose of the command marked with an arrow shown in the partial configuration output of a Cisco 806 broadband router?
defines which addresses are allowed out of the router
defines which addresses are allowed into the router
*** defines which addresses can be translated
defines which addresses are assigned to a NAT pool
10
Which configuration parameters are provided by the dynamic allocation process of DHCP? (Choose three.)
*** Gateway address
*** DNS server
DHCP Server
*** Subnet mask
Key server
ARP server
11
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.
12
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
13
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.
14
What is the default lease time for addresses assigned to clients through Easy IP?
*** twenty-four hours
forty-eight hours
one week
two weeks
15
Which of the following are broadcasts sent by a client to a DHCP server? (Choose two.)
*** DHCPDISCOVER
DHCPRELEASE
DHCPACK
*** DHCPREQUEST
DHCPOFFER
16
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
17
Which configuration information might a DHCPOFFER include? (Choose three.)
*** IP address
*** DNS server address
DHCP binding
*** Lease time
DHCP database
18

*** Configure the Miami router to use NAT.
Configure the Web Server with a private address.
*** Configure the Miami router to use PAT.
Change the Internet link IP address of 128.56.0.0 to a private address.
Configure the Tampa router to use PAT.
19
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.
20
