Q11.
Which programming languages or platforms often contain large amounts of internal symbolic information?

a.

Java and .NET

b.

Python and Ruby

c.

C++ and C#

d.

None of the above

Discuss
Answer: (a).Java and .NET Explanation:Bytecode-based programs, such as those in Java and .NET, often contain large amounts of internal symbolic information such as class names, class member names, and the names of instantiated global objects.
Q12.
What is the most fundamental feature of pretty much every bytecode obfuscator?

a.

Adding more symbolic information to the program

b.

Removing all symbolic information from the program

c.

Renaming all symbols into meaningless sequences of characters

d.

None of the above

Discuss
Answer: (c).Renaming all symbols into meaningless sequences of characters Explanation:The most fundamental feature of pretty much every bytecode obfuscator is to rename all symbols into meaningless sequences of characters.
Q13.
Why should software developers consider introducing antireversing measures into their programs?

a.

To hinder and obstruct reversers by making the process slow and painful.

b.

To entirely prevent reversing.

c.

To reduce the cost associated with antireversing approaches.

d.

To increase the readability of the program.

Discuss
Answer: (a).To hinder and obstruct reversers by making the process slow and painful. Explanation:Antireversing measures can slow down or obstruct reversers, but it's never possible to entirely prevent reversing.
Q14.
What is the main advantage of eliminating symbolic information from the program executable?

a.

It reduces the program's vulnerability to any kind of static analysis.

b.

It makes the program more readable.

c.

It improves the program's performance.

d.

It allows reversers to easily understand the program's internal structure.

Discuss
Answer: (a).It reduces the program's vulnerability to any kind of static analysis. Explanation:Eliminating symbolic information from the program executable reduces the program's vulnerability to any kind of static analysis.
Q15.
What is the purpose of embedding antidebugger code in a program?

a.

To hinder live analysis by reversing tools.

b.

To make the program more readable.

c.

To reduce the program's performance.

d.

To improve the program's robustness.

Discuss
Answer: (a).To hinder live analysis by reversing tools. Explanation:The purpose of embedding antidebugger code in a program is to hinder live analysis by reversing tools.
Q16.
What is information elimination?

a.

A process of removing symbolic information from a program

b.

A process of removing all information from a program

c.

A process of optimizing a program

d.

A process of adding information to a program

Discuss
Answer: (a).A process of removing symbolic information from a program Explanation:Information elimination can be defined as the process of removing symbolic information from a program.
Q17.
Which languages typically do not include symbolic information in release builds?

a.

Bytecode-based languages

b.

Compiler-based languages

c.

Assembly language

d.

Machine language

Discuss
Answer: (b).Compiler-based languages Explanation:Eliminating symbolic information is generally a nonissue in conventional compiler-based languages such as C and C++ because symbolic information is not usually included in release builds anyway.
Q18.
What is one area where even compiler-based programs can contain symbolic information?

a.

The import and export tables

b.

The main function

c.

The header file

d.

The linker

Discuss
Answer: (a).The import and export tables Explanation:One area where even compiler-based programs can contain a little bit of symbolic information is the import and export tables.
Q19.
Why might it be worthwhile to export all functions by ordinals rather than by names?

a.

To make the program more efficient

b.

To make the program more readable

c.

To make the program more secure

d.

To make the program more portable

Discuss
Answer: (c).To make the program more secure Explanation:If you are seriously concerned about people reversing your program, it might be worthwhile to export all functions by ordinals rather than by names.
Q20.
Why is the issue of symbolic information different with most bytecode-based languages?

a.

Because these languages often use names for internal cross-referencing instead of addresses

b.

Because these languages are more secure

c.

Because these languages are more efficient

d.

Because these languages are easier to program in

Discuss
Answer: (a).Because these languages often use names for internal cross-referencing instead of addresses Explanation:The issue of symbolic information is different with most bytecode-based languages because these languages often use names for internal cross-referencing instead of addresses.
