✓ Correct answers
- Schedule quick scans and randomize their start times across hosts.
- Retain real-time and cloud-delivered protection on live hosts.
Routine scheduled quick scans and randomized timing reduce synchronized workload. Keep real-time and cloud-delivered protection; image scanning and broad exclusions do not replace it. Option explanations: A. Disable live-host real-time protection and rely only on the base-image scan.: An image scan cannot protect later live-host activity and user downloads. B. Schedule quick scans and randomize their start times across hosts.: Quick scans and randomized starts follow the recommended VDI scheduling approach. C. Exclude every user's Downloads folder from protection.: A blanket Downloads exclusion creates a broad unprotected area and does not address scan scheduling correctly. D. Retain real-time and cloud-delivered protection on live hosts.: These protections should remain enabled while scan scheduling is optimized.
