CompTIA A+ 220-1202 (V15) Practice Question

Option A is correct because industry guidance recommends enabling both scheduled scans and automatic security-intelligence (definition) updates to detect new threats promptly. Microsoft Defender, for example, checks for updates before each scheduled scan and allows administrators to configure additional update intervals. Options B, C, and D all delay either scanning or updates (or disable real-time protection), leaving the system exposed to newly released malware.

References:

• Microsoft Defender documentation recommends scheduling scans and notes that Defender "checks for an update 15 minutes before the time of any scheduled scans" to ensure the latest signatures are used.
• Microsoft also states that "keeping Microsoft Defender Antivirus up to date is critical" and that security-intelligence updates occur on a scheduled cadence that should remain enabled.
