Which two NAT types allows only objects or groups to reference an IP address? (choose two)
A . dynamic NAT
B . dynamic PAT
C . static NAT
D . identity NAT
Answer: AC
Explanation:
Adding Network Objects for Mapped Addresses For dynamic NAT, you must use an object or group for the mapped addresses. Other NAT types have the option of using inline addresses, or you can create an object or group according to this section.
* Dynamic NAT:
+ You cannot use an inline address; you must configure a network object or group.
+ The object or group cannot contain a subnet; the object must define a range; the group can include hosts and ranges.
+ If a mapped network object contains both ranges and host IP addresses, then the ranges are used for dynamic NAT, and then the host IP addresses are used as a PAT fallback.
* Dynamic PAT (Hide):
+ Instead of using an object, you can optionally configure an inline host address or specify the interface address.
+ If you use an object, the object or group cannot contain a subnet; the object must define a host, or for a PAT pool, a range; the group (for a PAT pool) can include hosts and ranges.
* Static NAT or Static NAT with port translation:
+ Instead of using an object, you can configure an inline address or specify the interface address (for static NAT-with-port-translation).
+ If you use an object, the object or group can contain a host, range, or subnet.
* Identity NAT
+ Instead of using an object, you can configure an inline address.
+ If you use an object, the object must match the real addresses you want to translate.
