CompTIA Server+ (SK0-004) — Question 20

The last available backup is from 12 months ago. Which of the following should an administrator perform prior to applying a critical application patch to a guest
OS? (Choose two.)

Answer options

• A. Full backup
• B. Database snapshot
• C. Incremental backup
• D. Virtual machine snapshot
• E. File system copy

Correct answer: A, B

Explanation

A full backup ensures that all data is preserved before applying the patch, providing a complete restore point if needed. A database snapshot allows for recovery of the database state before the patch, which is critical for application stability. Incremental backups and file system copies do not provide the comprehensive safety that a full backup and database snapshot do in this scenario.
