Q181.
Why do sections need to be page-aligned when an executable is loaded into memory?

a.

To make the executable smaller on disk

b.

To make the executable faster when it is running

c.

To ensure that the memory manager can apply the correct access settings

d.

None of the above

Discuss
Answer: (c).To ensure that the memory manager can apply the correct access settings Explanation:Sections need to be page-aligned when an executable is loaded into memory so that the memory manager can apply the correct access settings.
Q182.
What are the two different kinds of alignment fields in the PE header?

a.

Section alignment and file alignment

b.

Memory alignment and disk alignment

c.

Data alignment and code alignment

d.

None of the above

Discuss
Answer: (a).Section alignment and file alignment Explanation:The two different kinds of alignment fields in the PE header are section alignment and file alignment.
Q183.
Why is alignment important when accessing an executable file?

a.

Because it makes the executable faster

b.

Because it causes some interesting phenomena

c.

Because it ensures that RVAs point to the correct place

d.

None of the above

Discuss
Answer: (c).Because it ensures that RVAs point to the correct place Explanation:Alignment is important when accessing an executable file because it ensures that RVAs (relative virtual addresses) point to the correct place.
Q184.
What is an RVA?

a.

A type of executable file format

b.

A type of memory page

c.

A relative virtual address

d.

None of the above

Discuss
Answer: (c).A relative virtual address Explanation:An RVA (relative virtual address) is a relative virtual address used to calculate distances within an executable when it is mapped as an executable.
Q185.
What is the difference between section alignment and file alignment?

a.

Section alignment is how sections are aligned on disk, while file alignment is how sections are aligned in memory.

b.

Section alignment is how sections are aligned in memory, while file alignment is how sections are aligned on disk.

c.

There is no difference between section alignment and file alignment.

d.

None of the above

Discuss
Answer: (b).Section alignment is how sections are aligned in memory, while file alignment is how sections are aligned on disk. Explanation:Section alignment is how sections are aligned in memory, while file alignment is how sections are aligned on disk.
Q186.
What are DLLs?

a.

A type of executable file

b.

A programming language

c.

A component of the operating system

d.

A way to reduce program memory consumption

Discuss
Answer: (d).A way to reduce program memory consumption Explanation:DLLs are a way to reduce program memory consumption by breaking a program into more than one executable file, where each executable is responsible for one feature or area of program functionality.
Q187.
What is the benefit of using DLLs?

a.

It allows for build-time static linking

b.

It reduces overall system memory consumption

c.

It increases program memory consumption

d.

It makes individual components harder to replace or upgrade

Discuss
Answer: (b).It reduces overall system memory consumption Explanation:From the operating system’s standpoint, DLLs can dramatically reduce overall system memory consumption because the system can detect that a certain executable has been loaded into more than one address space and just map it into each address space instead of reloading it into a new memory location.
Q188.
How do DLLs differ from build-time static libraries?

a.

DLLs are permanently linked into an executable

b.

Static libraries are loaded into memory twice

c.

The operating system has no way of knowing that parts of an executable came from a library

d.

DLLs are loaded only when the features they implement are required

Discuss
Answer: (d).DLLs are loaded only when the features they implement are required Explanation:DLLs are different from build-time static libraries because the latter are permanently linked into an executable while it is being built, while DLLs are loaded only when the features they implement are required.
Q189.
What happens when two executables are statically linked to the same library?

a.

The library code is loaded into memory twice

b.

The operating system detects that the library code is already loaded and maps it into each address space

c.

The library code is not loaded into memory

d.

The operating system has no way of knowing that the two executables contain parts that are identical

Discuss
Answer: (a).The library code is loaded into memory twice Explanation:When two executables are statically linked to the same library, the library code will essentially be loaded into memory twice, because the operating system will have no idea that the two executables contain parts that are identical.
Q190.
What is a DLL?

a.

An executable responsible for one feature or area of program functionality.

b.

A feature in Windows that reduces overall program memory consumption.

c.

An executable that is loaded into memory multiple times to reduce memory consumption.

d.

A library of functions that can be called by an executable at runtime.

Discuss
Answer: (d).A library of functions that can be called by an executable at runtime. Explanation:A DLL is a library of functions that can be called by an executable at runtime.
