Suggested answer: B

The same set of servers provides multiple services, that is, using different ports to provide different services at the same time. The stem requirement is based on server connection balancing, not server + port, so it is node.

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

Answers
Suggested answer: C

Explanation:

The topic explains that the connection reset behavior is caused by the vs configuration rather than the server resource problem. The answers B C are all configuration at the service forwarding level. If there is a problem with the configuration, it is all a problem rather than some users. Answer C's Connection Limit will cause a reset behavior when the connection reaches the threshold.
