Q141.
What is the most significant penalty incurred by most antireversing techniques?

a.

Slowing the program down

b.

Making the program harder to understand

c.

Removing important functionality from the program

d.

None of the above

Discuss
Answer: (a).Slowing the program down Explanation:The most significant penalty incurred by most antireversing techniques is in runtime performance; they just slow the program down.
Q142.
What does the magnitude of investment in antireversing measures eventually boil down to?

a.

How performance-sensitive is the program versus how concerned are you about piracy and reverse engineering?

b.

How many people will use the program?

c.

How long it takes to develop the program?

d.

None of the above

Discuss
Answer: (a).How performance-sensitive is the program versus how concerned are you about piracy and reverse engineering? Explanation:The magnitude of investment in antireversing measures will eventually boil down to simple economics: How performance-sensitive is the program versus how concerned are you about piracy and reverse engineering?
Q143.
What is obfuscation?

a.

A set of techniques aimed at reducing the program's vulnerability to any kind of static analysis.

b.

A process of adding symbolic information to the program executable.

c.

A technique used to enhance the performance of the program.

d.

A method of debugging the program.

Discuss
Answer: (a).A set of techniques aimed at reducing the program's vulnerability to any kind of static analysis. Explanation:Obfuscation is a set of techniques aimed at reducing the program's vulnerability to any kind of static analysis.
Q144.
What is a deobfuscator?

a.

A program that implements various data-flow analysis algorithms on an obfuscated program to remove all irrelevant instructions and restore the code's original structure

b.

A program that adds irrelevant instructions to a program to make it more difficult to reverse engineer

c.

A program that compresses an obfuscated program to reduce its runtime memory consumption

d.

A program that reorders the instructions in a program to make it less human-readable

Discuss
Answer: (a).A program that implements various data-flow analysis algorithms on an obfuscated program to remove all irrelevant instructions and restore the code's original structure Explanation:A deobfuscator is a program that implements various data-flow analysis algorithms on an obfuscated program which sometimes enable it to separate the wheat from the chaff and automatically remove all irrelevant instructions and restore the code's original structure.
Q145.
What is the associated cost of an obfuscating transformation?

a.

A larger code

b.

Slower execution times

c.

Increased memory runtime consumption

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The associated cost of an obfuscating transformation can be in the form of larger code, slower execution times, or increased memory runtime consumption.
Q146.
What are opaque predicates?

a.

A fundamental building block for control flow transformations

b.

A logical statement whose outcome is constant and is known in advance

c.

An antidisassembling technique

d.

None of the above

Discuss
Answer: (b).A logical statement whose outcome is constant and is known in advance Explanation:Opaque predicates are a logical statement whose outcome is constant and is known in advance.
