| Question ID 14558 | Refer to the exhibit.
A company wants to use NAT in the network shown. Which commands will apply the NAT
configuration to the proper interfaces? (Choose two.)
|
| Option A | R1(config)# interface serial0/1 R1(config-if)# ip nat inside
|
| Option B | R1(config)# interface serial0/1 R1(config-if)# ip nat outside
|
| Option C | R1(config)# interface fastethernet0/0 R1(config-if)# ip nat inside
|
| Option D | R1(config)# interface fastethernet0/0 R1(config-if)# ip nat outside
|
| Option E | R1(config)# interface serial0/1 R1(config-if)# ip nat outside source pool 200.2.2.18 255.255.255.252
|
| Option F | R1(config)# interface fastethernet0/0 R1(config-if)# ip nat inside source 10.10.0.0 255.255.255.0
|
| Correct Answer | B,C |
Explanation Explanation: For NAT, you need to define which interfaces are inside and which are outside. The outside interface is the one that connects to the external network, and the one that will be used for translating addresses. The inside interface is for the internal network, and defines the network IP addresses that will get translated to the one specified in the outside network.
| Question ID 14559 | A network administrator cannot connect to a remote router by using SSH. Part of the show
interfaces command is shown.
router#show interfaces
Serial0/1/0 is up, line protocol is down
At which OSI layer should the administrator begin troubleshooting?
|
| Option A | physical
|
| Option B | data link
|
| Option C | network
|
| Option D | transport
|
| Correct Answer | B |
Explanation Explanation: https://learningnetwork.cisco.com/thread/12389 I think the indication here is "Serial 0 is up, line protocol is down". What causes this indication? Correct me if I am wrong. When you have this indication, a cable unplugged is not a correct answer. If you check the output of your "show interface serial 0" command again, you should notice it as "Serial 0 is down, line protocol is down. Under the "show ip int brief" you should see status = down and protocol = down as opposed to up, down. Because you disconnected the cable, layer 1 will go down, which is indicated by the serial 0 down status. The line protocol status is for layer 2. So, a cable unplugged is not a correct answer to "Serial 0 is up, line protocol is down". Up/down means that the physical layer is OK, but there is a problem with the data link link (line protocol).
