Question 3

A BIG-IP Administrator uses backend servers to host multiple services per server. There are multiple
virtual servers and pools defined, referencing the same backend servers.
Which load balancing algorithm is most appropriate to have an equal number of connections on each
backend server?

  • A. Least Connections (member)
  • B. Least Connections (node)
  • C. Predictive (member)
  • D. Predictive (node)
Mark Question:
Answer:

B


Explanation:
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.

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
