Q81.
Why is it rarely necessary to read raw IL code?

a.

Raw IL code is too difficult to read

b.

Decompilers can produce a high-level language representation of the code

c.

Raw IL code is not relevant to programming

d.

None of the above

Discuss
Answer: (b).Decompilers can produce a high-level language representation of the code Explanation:It is rarely necessary to read raw IL code because decompilers can produce a high-level language representation of the code.
Q82.
What is program comprehension?

a.

The process of writing a program in a high-level language

b.

The process of reading a program in a high-level language and trying to figure out what it does

c.

The process of decompiling a program

d.

None of the above

Discuss
Answer: (b).The process of reading a program in a high-level language and trying to figure out what it does Explanation:Program comprehension is the process of reading a program in a high-level language and trying to figure out what it does.
Q83.
What is the benefit of using a decompiler such as Spices.Net?

a.

It can decompile code into any language

b.

It eliminates references to the "this" object

c.

It makes reading IL code easier

d.

None of the above

Discuss
Answer: (a).It can decompile code into any language Explanation:Decompilers such as Spices.Net allow you to decompile code into any language you choose, regardless of the original language in which the program was written.
Q84.
What is the vulnerability of .NET executables that makes obfuscation necessary?

a.

They contain human-readable symbol names

b.

They are written in a high-level language

c.

They are easy to reverse engineer

d.

They are susceptible to malware attacks

Discuss
Answer: (c).They are easy to reverse engineer Explanation:.NET executables are easy to reverse engineer because IL code is highly detailed and can be easily decompiled into a very readable high-level language representation.
Q85.
What is the common strategy for obfuscating .NET executables?

a.

Eliminating symbol names from the executable

b.

Renaming symbol names in a meaningful way

c.

Encrypting the entire executable

d.

Hiding the executable in a separate file

Discuss
Answer: (a).Eliminating symbol names from the executable Explanation:The common strategy for obfuscating .NET executables is to eliminate human-readable symbol names from the executable by renaming them to cryptic, meaningless names.
Q86.
Can obfuscation prevent reverse engineering of .NET executables completely?

a.

Yes

b.

No

c.

May be Yes or No

d.

Can't say

Discuss
Answer: (b).No Explanation:Obfuscation can make reverse engineering of .NET executables more difficult, but it cannot prevent it completely.
Q87.
Why is obfuscation more common for .NET executables than for native executables?

a.

.NET executables are written in a high-level language

b.

.NET executables contain human-readable symbol names

c.

Native executables are susceptible to malware attacks

d.

Native executables are difficult to read in assembly language

Discuss
Answer: (b)..NET executables contain human-readable symbol names Explanation:.NET executables contain full-blown, human-readable symbol names for method parameters, class names, field names, and method names, which makes them more vulnerable to reverse engineering.
Q88.
What is the purpose of obfuscating .NET executables?

a.

To make them easier to read and understand

b.

To make them more vulnerable to reverse engineering

c.

To prevent quick decompilation of the program

d.

To make them run faster

Discuss
Answer: (c).To prevent quick decompilation of the program Explanation:Obfuscating .NET executables is done to prevent quick decompilation of the program and make it more difficult for reverse engineering.
Q89.
Why is renaming symbols a common strategy for obfuscating .NET executables?

a.

To make the program run faster

b.

To make the program more readable

c.

To prevent people from reverse engineering it

d.

To make it easier to identify elements within the program

Discuss
Answer: (c).To prevent people from reverse engineering it Explanation:Renaming symbols with cryptic, meaningless names instead of their original names makes it more difficult for people to reverse engineer the program.
Q90.
What is control flow obfuscation?

a.

Modifying a program's control flow structure to make it less readable

b.

Creating a program that is easy to decompile

c.

Creating a program that is vulnerable to reverse engineering

d.

Breaking a program's encryption

Discuss
Answer: (a).Modifying a program's control flow structure to make it less readable Explanation:Control flow obfuscation is the concept of modifying a program's control flow structure to make it less readable and more difficult to decompile.
