- It uses the source TCP or UDP port number on the incoming packet.
- It uses a combination of the source TCP or UDP port number and the destination IP address on the incoming packet.

Question 4 of 22

4. Question
1 points
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 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 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

8. Question
1 points
What is the major benefit of using NAT with Port Address Translation?
- It allows external hosts access to internal servers.
- It improves network performance for real-time protocols.
- It allows many internal hosts to share the same public IPv4 address.
- It provides a pool of public addresses that can be assigned to internal hosts.
Correct

Incorrect
Question 9 of 22

9. Question
1 points
What is a characteristic of unique local addresses?

Correct

Incorrect
Question 10 of 22

10. Question
1 points
A network administrator configures the border router with the command R1(config)# ip nat inside source list 4 pool corp. What is required to be configured in order for this particular command to be functional?
- a NAT pool named corp that defines the starting and ending public IP addresses
- an access list named corp that defines the private addresses that are affected by NAT
- an access list numbered 4 that defines the starting and ending public IP addresses
- ip nat outside to be enabled on the interface that connects to the LAN affected by the NAT
- a VLAN named corp to be enabled and active and routed by R1

Question 11 of 22

11. Question
1 points
Which statement describes IPv6 ULAs?

- They begin with the fe80::/10 prefix.
- They are assigned by an ISP.
- They are not routable across the internet.
Correct

Incorrect
Question 12 of 22

12. Question
1 points
What is the purpose of port forwarding?
- Port forwarding allows an external user to reach a service on a private IPv4 address that is located inside a LAN.
- Port forwarding allows users to reach servers on the Internet that are not using standard port numbers.
- Port forwarding allows an internal user to reach a service on a public IPv4 address that is located outside a LAN.
- Port forwarding allows for translating inside local IP addresses to outside local addresses.
Correct

Incorrect
Question 13 of 22

13. Question
1 points
When dynamic NAT without overloading is being used, what happens if seven users attempt to access a public server on the Internet when only six addresses are available in the NAT pool?
- No users can access the server.
- The request to the server for the seventh user fails.
- All users can access the server.
- The first user gets disconnected when the seventh user makes the request.
Correct

Incorrect
Question 14 of 22

14. Question
1 points
A network engineer has configured a router with the command ip nat inside source list 4 pool corp overload. Why did the engineer use the overload option?
- The company has more private IP addresses than available public IP addresses.
- The company needs to have more public IP addresses available to be used on the Internet.
- The company router must throttle or buffer traffic because the processing power of the router is not enough to handle the normal load of external-bound Internet traffic.
- The company has a small number of servers that should be accessible by clients from the Internet.
Correct

Question 15 of 22

15. Question

5 points

Match the steps with the actions that are involved when an internal host with IP address 192.168.10.10 attempts to send a packet to and external server at the IP address 209.165.200.254 across a router R1 that running dynamic NAT. (Not all options are used.)

Sort elements

step 5
step 2
step 4
step 1
step 3

R1 replaces the address 192.168.10.10 with a translated inside global address.

R1 checks the NAT configuration to determine if this packet should be translated.

R1 selects an available global address from the dynamic address pool.

The cost sends packets that request a connection to the server at the address 209.165.200.254

If there is no translation entry for this IP address, R1 determines that the source address 192.168.10.10 must be translated.

Correct

Incorrect

Question 16 of 22

16. Question
1 points
What is a disadvantage of NAT?
- There is no end-to-end addressing.
- The router does not need to alter the checksum of the IPv4 packets.
- 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.
Correct

Incorrect
Question 17 of 22

17. Question
1 points
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 can be translated

- defines which addresses are assigned to a NAT pool
- defines which addresses are allowed out of the router
Correct

Incorrect
Question 18 of 22

18. Question
2 points

- Define a pool of global addresses to be used for overload translation.
- Create a standard access list to define applications that should be translated.
- Define the range of source ports to be used.

Correct

Incorrect
Question 19 of 22

19. Question
1 points

- Interface S0/0/0 should be identified as the outside NAT interface.
- Interface Fa0/1 should be identified as the outside NAT interface.
- The IP NAT statement is incorrect.
- The configuration is missing a valid access control list.
Correct

Incorrect
