Which of the following should be considered true when selecting a 64-bit version of Windows?
The correct answer is C. Many browser plug-ins may only be supported on 32-bit browsers. A key consideration when deploying 64-bit Windows is that many legacy browser plug-ins were only compiled in 32-bit, requiring users to run a 32-bit browser to use them. The other statements contain factual inaccuracies about 64-bit behavior.
Question
Which of the following should be considered true when selecting a 64-bit version of Windows?
Options
- A64-bit extensions can be disabled in the bios and prevent a proper boot.
- BXP Compatibility mode only allows for the 64-bit version of Windows XP.
- CMany browser plug-ins may only be supported on 32-bit browsers.
- D64-bit uses memory more efficiently so less RAM is needed than in a 32-bit version.

Why each option
A key consideration when deploying 64-bit Windows is that many legacy browser plug-ins were only compiled in 32-bit, requiring users to run a 32-bit browser to use them. The other statements contain factual inaccuracies about 64-bit behavior.
64-bit extensions (NX/XD bit, PAE) are CPU hardware flags that affect execution security features; disabling NX in BIOS does not prevent Windows from booting.
Windows XP Compatibility Mode (Windows XP Mode) in Windows 7 runs a virtualized 32-bit Windows XP environment; it is not exclusive to or restricted to a 64-bit version of XP.
Because most browser plug-ins (such as older versions of Adobe Flash, Java, and various media players) were compiled only as 32-bit binaries, a 64-bit browser cannot load them. Users on 64-bit Windows often needed to use the 32-bit version of Internet Explorer or another 32-bit browser to access plug-in-dependent content.
64-bit Windows typically requires more RAM than a 32-bit installation because 64-bit pointers and OS structures are larger, not less RAM.
