SK0-004 · Question #743
An administrator has been given an OS DVD to install on a server. During setup, however, the DVD gives an architecture mismatch warning. Which of the following is the MOST likely cause of the issue?
The correct answer is B. The administrator is trying to install a 64-bit OS on a system with 32-bit CPUs. An architecture mismatch occurs when the OS CPU architecture does not match the server's processor type, such as attempting to install a 64-bit OS on a 32-bit CPU.

Why each option
An architecture mismatch occurs when the OS CPU architecture does not match the server's processor type, such as attempting to install a 64-bit OS on a 32-bit CPU.
ECC memory is error-correcting RAM used for reliability and has no bearing on OS CPU architecture compatibility.
A 64-bit operating system requires a CPU that supports 64-bit instruction sets; a system with 32-bit CPUs physically cannot execute 64-bit code. This incompatibility is detected during setup and produces the architecture mismatch warning observed by the administrator.
Multicore CPUs are fully compatible with both 32-bit and 64-bit operating systems and do not trigger architecture mismatch errors.
An outdated BIOS may cause hardware detection or feature support issues but does not produce a CPU architecture mismatch warning during OS installation.
