Q171.
Why does an executable need to know in advance where it will be loaded?

a.

Because it contains many cross-references

b.

Because it's compressed

c.

Because it's dynamic

d.

Because it's immutable

Discuss
Answer: (a).Because it contains many cross-references Explanation:An executable needs to know in advance where it will be loaded because it contains many cross-references, where one position in the code is pointing at another position in the code.
Q172.
What does it mean for an executable file to be relocatable?

a.

It can only be loaded at a specific virtual address

b.

It can be loaded at a different virtual address each time it is loaded

c.

It cannot be relocated after it has been loaded

d.

It does not coexist with other executables

Discuss
Answer: (b).It can be loaded at a different virtual address each time it is loaded Explanation:A relocatable executable file can be loaded at different virtual addresses each time it is loaded.
Q173.
Why does an executable file need to know in advance where it will be loaded?

a.

To prevent other executables from being loaded in the same address space

b.

To make sure the file is loaded only once

c.

To avoid cross-references in the code

d.

To generate logic that calculates the exact address of the global variable

Discuss
Answer: (d).To generate logic that calculates the exact address of the global variable Explanation:An executable file needs to know in advance where it will be loaded in order to generate logic that calculates the exact address of the global variable.
Q174.
What is a relative virtual address (RVA)?

a.

An absolute address in an executable header

b.

An offset into the file

c.

A virtual address where the executable is loaded

d.

A base address assigned to each module

Discuss
Answer: (b).An offset into the file Explanation:An RVA is an offset into the file that is used to calculate real virtual addresses when the file is loaded.
Q175.
Why are relocations important for executable files?

a.

They prevent cross-references in the code

b.

They ensure that the file is loaded only once

c.

They calculate the exact address of the global variable

d.

They modify absolute addresses in the code to point to the right place

Discuss
Answer: (d).They modify absolute addresses in the code to point to the right place Explanation:Relocations modify absolute addresses in the code to make sure that they point to the right place when the file is loaded.
Q176.
What is a section in an executable image?

a.

A division of the file where contents are stored

b.

A header that contains information about the executable

c.

A function that is executed when the program runs

d.

A module that is loaded into the program's address space

Discuss
Answer: (a).A division of the file where contents are stored Explanation:A section is a division of an executable image where the file's contents are stored.
Q177.
What is the purpose of having different sections in an executable image?

a.

To store code and data in different areas of the file

b.

To make it easier to debug the program

c.

To improve the performance of the program

d.

To provide a way to organize the program's modules

Discuss
Answer: (a).To store code and data in different areas of the file Explanation:Different sections in an executable image are used to store code and data in different areas of the file, so that they can be treated differently by the memory manager when the module is loaded.
Q178.
What is a code section in an executable image?

a.

A section that contains the executable's code

b.

A section that contains uninitialized data

c.

A section that contains system resources

d.

A section that contains debugging information

Discuss
Answer: (a).A section that contains the executable's code Explanation:A code section is a section in an executable image that contains the executable's code.
Q179.
What is an RVA in an executable image?

a.

An offset into the file

b.

A relative address that is used for relocation

c.

A virtual address that is assigned to a module

d.

A section in an executable image

Discuss
Answer: (a).An offset into the file Explanation:RVA stands for relative virtual address, which is an offset into the file. When the file is loaded, the loader calculates real virtual addresses out of RVAs by adding the module's base address to an RVA.
Q180.
What is an initialized data section in an executable image?

a.

A section that contains the contents of initialized variables

b.

A section that contains uninitialized variables

c.

A section that contains system resources

d.

A section that contains debugging information

Discuss
Answer: (a).A section that contains the contents of initialized variables Explanation:An initialized data section is a section in an executable image that contains the contents of any initialized variable defined anywhere in the program. For example, a string defined as char szMessage[] = "Welcome to my program!" will be stored in an initialized data section.
