A+ Lesson

Application Requirements and Compatibility Checks for A+

Last updated: 6/10/2026

Short answer

Before installing, confirm the application's documented system requirements against the device: CPU family/speed, RAM minimum, graphics type and VRAM, storage free space and filesystem compatibility, OS version and bitness, and presence/driver needs for any external hardware tokens. Use system information tools (OS built-in system info, device manager, disk manager) and vendor documentation. If any requirement is unmet, document the shortfall and present options: upgrade hardware, choose an alternate app, or decline installation per policy.

Why it appears on the exam

- Identify which requirement mismatch will block installation (example: 32-bit OS vs. 64-bit installer). - Given system info and an app spec sheet, decide whether to proceed and list remediation steps if not supported. - Select the correct order of checks during pre-install triage.

Key concepts

Concept 1

Required terms

32-bit vs. 64-bit: Whether the application binary and target OS use 32-bit or 64-bit architecture; mismatches can prevent installation or operation. VRAM: Video RAM available to the GPU that affects graphics performance; some apps specify minimum VRAM. external hardware token: A physical hardware device required for authentication or DRM; may need drivers or firmware for the OS.

Example

A game requires x64 OS and 4 GB VRAM; the target device has a 64-bit CPU but a 32-bit OS and integrated graphics with shared RAM. Action: do not install; recommend OS upgrade and dedicated GPU.

Concept 2

How Application Requirements and Compatibility Checks works

Before installing, confirm the application's documented system requirements against the device: CPU family/speed, RAM minimum, graphics type and VRAM, storage free space and filesystem compatibility, OS version and bitness, and presence/driver needs for any external hardware tokens. Use system information tools (OS built-in system info, device manager, disk manager) and vendor documentation. If any requirement is unmet, document the shortfall and present options: upgrade hardware, choose an alternate app, or decline installation per policy.

Example

A CAD tool needs a USB hardware dongle. Confirm the dongle driver is available for the target OS and test with vendor utility before installing the app.

Concept 3

Common confusion

- Confusing system RAM requirements with VRAM requirements for graphics-intensive apps. - Thinking a 64-bit CPU implies the OS is 64-bit and will accept 64-bit apps. - Assuming external tokens will work out of the box without vendor drivers or services.

Example

An installer requires 20 GB free on C:. Verify free space and whether the installer allows custom install location.

Concept 4

Core 2 (220-1202) question cues

Identify which requirement mismatch will block installation (example: 32-bit OS vs. 64-bit installer); Given system info and an app spec sheet, decide whether to proceed and list remediation steps if not supported; Select the correct order of checks during pre-install triage.

Example

A game requires x64 OS and 4 GB VRAM; the target device has a 64-bit CPU but a 32-bit OS and integrated graphics with shared RAM. Action: do not install; recommend OS upgrade and dedicated GPU.
