QUESTION 154

Which of the following statements represents the most suitable description of a required signature

parameter attribute?

B. The default signature parameter value cannot be changed.

C. The signature parameter must be defined for all signatures.

D. The signature parameter value can be defined for custom signatures only.

Answer: C

QUESTION 155

Which of the following statements represents the best description of a protected signature parameter

attribute?

A. The signature parameter value cannot be modified for custom signatures.

B. The signature parameter value must be defined for all signatures.

C. The default signature parameter value cannot be changed.

D. The signature parameter value can be modified for custom signatures only.

Answer: C

Explanation:

Protected-The protected attribute of the parameter applies only to the default signature set. When a default

signature parameter is protected, its value cannot be modified meaning that the fundamental behavior of the

default signature cannot be changed. For example, you can modify certain parameters (AlarmThrottle,

ChokeThreshold, Unique) of default signatures, but not the underlying functionality, such as TcpFlags and

Mask.

Note: If a parameter is protected, you cannot change it for the default signatures. You can modify it for custom

signatures.

D is better than C, because it covers both, DEFAULT and CUSTOM signatures - by the word "only".
