One of the servers on the network stops responding due to lack of available memory. Server administrators did not have a clear definition of what action should
have taken place based on the available memory. Which of the following would have BEST kept this incident from occurring?

A.
Set up a protocol analyzer

B.
Set up a performance baseline

C.
Review the systems monitor on a monthly basis

D.
Review the performance monitor on a monthly basis

Explanation:
A performance baseline provides the input needed to design, implement, and support a secure network. The performance baseline would define the actions that
should be performed on a server that is running low on memory.
Incorrect Answers:
A: A Protocol Analyzer is a hardware device or more commonly a software program used to capture network data communications sent between devices on a
network. It is not used to provide guidance on the actions that should be performed on a server that is running low on memory. Therefore, this answer is incorrect.
C: Reviewing the systems monitor on a monthly basis may help to determine that the server is running low on memory. However, the server could run out of
memory in between reviews. The system monitor also does not provide guidance on the actions that should be performed on a server that is running low on
memory. Therefore this is not the best answer and is therefore incorrect.
D: Reviewing the performance monitor on a monthly basis may help to determine that the server is running low on memory. However, the server could run out of
memory in between reviews. The performance monitor also does not provide guidance on the actions that should be performed on a server that is running low on
memory. Therefore this is not the best answer and is therefore incorrect.
