Chapter 9: NAT for IPv4 (NetAcad) (Exam)
**NEEDS UPDATING - 43.9% CORRECT**
any address in the 10.1.1.0 network
Refer to the exhibit. Which address or addresses represent the inside global address?
192.168.0.100
209.165.20.25
10.1.1.2
any address in the 10.1.1.0 network
What is a disadvantage of NAT?
There is no end-to-end addressing.
The internal hosts have to use a single public IPv4 address for external communication.
The costs of readdressing hosts can be significant for a publicly addressed network.
The router does not need to alter the checksum of the IPv4 packets.
There is no end-to-end addressing.
A network administrator is configuring a static NAT on the border router for a web server located
in the DMZ network. The web server is configured to listen on TCP port 8080. The web server is
paired with the internal IP address of 192.168.5.25 and the external IP address of
209.165.200.230. For easy access by hosts on the Internet, external users do not need to
specify the port when visiting the web server. Which command will configure the static NAT?
R1(config)# ip nat inside source static tcp 209.165.200.230 80 192.168.5.25 8080
R1(config)# ip nat inside source static tcp 209.165.200.230 8080 192.168.5.25 80
R1(config)# ip nat inside source static tcp 192.168.5.25 80 209.165.200.230 8080
R1(config)# ip nat inside source static tcp 192.168.5.25 8080 209.165.200.230 80
, R1(config)# ip nat inside source static tcp 192.168.5.25 8080 209.165.200.230 80
What is the primary purpose of NAT?
enhance network performance
allow peer-to-peer file sharing
conserve IPv4 addresses
X-increase network security
(corrected)
conserve IPv4 addresses
Interface S0/0/0 should be identified as the outside NAT interface
Refer to the exhibit. A technician is configuring R2 for static NAT to allow the client to access the
web server. What is a possible reason that the client PC cannot access the web server?
The configuration is missing a valid access control list.
The IP NAT statement is incorrect.
Interface S0/0/0 should be identified as the outside NAT interface.
Interface Fa0/1 should be identified as the outside NAT interface.
defines which addresses are allowed out of the router
Refer to the exhibit. What is the purpose of the command marked with an arrow shown in the
partial configuration output of a Cisco broadband router?
defines which addresses are allowed into the router
defines which addresses are allowed out of the router
defines which addresses can be translated
defines which addresses are assigned to a NAT pool
Which statement describes IPv6 ULAs?
