A. policy NAT
B. dynamic PAT
C. static NAT
D. dynamic NAT
E. policy PAT
Correct Answer: B

Use the following guidelines to configure either Dynamic NAT or PAT:
First configure a nat command, identifying the real addresses on a given interface that you want to translate.
Then configure a separate global command to specify the mapped addresses when exiting another interface.
(In the case of PAT, this is one address.) Each nat command matches a global command by comparing the NAT ID, a number that you assign to each command. Note The configuration for dynamic NAT and PAT are almost identical; for NAT you specify a range of mapped addresses, and for PAT you specify a single address. Figure 29-9 shows a typical dynamic NAT scenario. Only translated hosts can create a NAT session, and responding traffic is allowed back. The mapped address is dynamically assigned from a pool defined by the global command.

Figure 29-10 shows a typical dynamic PAT scenario. Only translated hosts can create a NAT session, and responding traffic is allowed back. The mapped address defined by the global command is the same for each translation, but the port is dynamically assigned.
