Application Impact Considerations for A+
Short answer
Consider four impact domains: - Device: CPU, memory, storage, GPU, battery. Heavy resource use can require hardware upgrades or alternative software. - Network: Frequency and size of data transfers, sync intervals, and real-time features like videoconferencing that demand bandwidth and low latency. - Operational: How updates, backups, and administrative management must change; e.g., nightly backups may need rescheduling to avoid conflict with large sync jobs. - Business: Licensing cost, compliance, data residency, and how the app affects workflows or SLAs.
Why it appears on the exam
- Given a scenario, identify the primary impact domain and choose an appropriate mitigation (e.g., bandwidth throttling for network-heavy apps). - Prioritize actions when an app's resource use conflicts with operational windows (backup, maintenance).
Key concepts
Concept 1
Required terms
device impact: How the application uses local resources: CPU, RAM, GPU, storage, and battery. network impact: How the application generates network traffic and bandwidth consumption, including sync and cloud components. operational impact: Effects on day-to-day operations: backup windows, update schedules, and admin overhead.
Example
A sync-heavy cloud storage app will increase upload bandwidth; mitigate by setting selective sync or scheduling large syncs for off-hours.
Concept 2
How Application Impact Considerations works
Consider four impact domains: - Device: CPU, memory, storage, GPU, battery. Heavy resource use can require hardware upgrades or alternative software. - Network: Frequency and size of data transfers, sync intervals, and real-time features like videoconferencing that demand bandwidth and low latency. - Operational: How updates, backups, and administrative management must change; e.g., nightly backups may need rescheduling to avoid conflict with large sync jobs. - Business: Licensing cost, compliance, data residency, and how the app affects workflows or SLAs.
Example
A new video-editing application will demand GPU and VRAM; recommend a hardware upgrade or use of cloud rendering services if available.
Concept 3
Common confusion
- Overlooking background services that run with the app and consume resources even when the app window is closed. - Failing to account for cumulative effects when multiple resource-heavy apps are installed on the same device.
Example
An app requires payment per seat; quantify business cost before approving widespread installation.

Core 2 (220-1202) question cues
Given a scenario, identify the primary impact domain and choose an appropriate mitigation (e.g., bandwidth throttling for network-heavy apps); Prioritize actions when an app's resource use conflicts with operational windows (backup, maintenance).
Example
A sync-heavy cloud storage app will increase upload bandwidth; mitigate by setting selective sync or scheduling large syncs for off-hours.
