220-1102 Question 133
Single answerSystemA technician is preparing a Windows 11 laptop for a remote employee who needs to run an older line-of-business application that is known to crash on 32-bit operating systems and requires at least 8 GB of RAM. The employee also wants the laptop to support full-disk encryption and to boot securely. Which system type should the technician verify is installed to best meet these requirements?
- A
32-bit operating system on an x86 processor
- B
64-bit operating system on an x64 processor with UEFI support
- C
32-bit operating system on an ARM processor
- D
Legacy BIOS-based system with a 64-bit operating system
Show answer and explanation
Correct answer: B
Explanation
The best answer is a 64-bit operating system on an x64 processor with UEFI support. In A+ Core 2, candidates are expected to understand system requirements and how operating system architecture affects application support, memory usage, and security features. A 64-bit OS is the proper choice for systems with 8 GB of RAM and for modern Windows deployments. UEFI is preferred over Legacy BIOS because it supports Secure Boot, which helps protect the boot process from tampering. For full-disk encryption in business environments, BitLocker is commonly used and typically relies on supported hardware such as TPM along with modern firmware capabilities. Microsoft documentation on Windows system requirements and security features consistently emphasizes 64-bit architecture, UEFI, and Secure Boot for current Windows platforms.
- A. Incorrect.
This is incorrect because a 32-bit operating system has practical memory limitations and is not the best choice for a system that needs to reliably use 8 GB of RAM and run modern Windows 11 business workloads. It also does not best align with current enterprise security expectations such as Secure Boot support. A candidate might choose this if they confuse processor compatibility with application compatibility.
- B. Correct.
This is correct because a 64-bit operating system on an x64 processor is appropriate for systems requiring 8 GB of RAM and compatibility with modern business applications. UEFI support is also important because it enables Secure Boot, and when paired with TPM, it supports common enterprise security features such as BitLocker. This combination best satisfies the memory, application, encryption, and secure boot requirements in the scenario.
- C. Incorrect.
This is incorrect because a 32-bit operating system would still be a poor fit for the RAM requirement, and ARM introduces additional application compatibility concerns for older line-of-business software. Someone might choose this option by focusing only on newer hardware trends instead of verifying whether the required legacy application will run properly.
- D. Incorrect.
This is incorrect because although a 64-bit operating system helps with memory support, Legacy BIOS does not provide Secure Boot, which is specifically part of the user's requirement. This makes it less suitable than a UEFI-based system. A candidate might pick this if they know 64-bit is needed for RAM usage but overlook the security and boot requirement.
