Explanation
About audit logging
Audit logging is an optional feature that togs messages whenever a BIG-IP system object, such as a virtual server or a load balancing pool, is confined (that is. created, modified, or deleted). The BiGIP system logs the messages for these auditing events in the file /var/log'audit There are three ways that objects can be configured
* By user action
* By system action
* By loading configuration data
Whenever an object is configured in one of these ways, the BIG-IP system logs a message to the audit log
質問 # 115
A site wishes to perform source address translation on packets arriving from the Internet for clients using some pools but not others. The determination is not based on the client's IP address, but on the pool they are load balanced to. What could best accomplish this goal.

- B. The decision to perform source address translation is always based on VLAN. Thus, the goal cannot be achieved.
- C. A SNAT for all addresses could
be defined,
and then disable the SNAT processing for select pools. - D. The decision to perform source address translation is always based on a client's address (or network). Thus, this goal cannot be achieved.
