MySQL 1Z0-908 Guide: Database Administrator

1Z0-908 is an operations and safety exam. Strong answers usually come from choosing the safest workable option for backup, recovery, replication, security, and maintenance rather than the flashiest feature.

RPO: Recovery point objective, or how much data loss the business can tolerate.

Binary log: The MySQL change log used for replication and point-in-time recovery workflows.

What this guide emphasizes

• Installation, configuration, and safe operational defaults
• Backups, restore paths, and binary-log-aware recovery
• Replication, failover, and high-availability tradeoffs
• Security, monitoring, and troubleshooting choices under pressure

What strong answers usually do

• Start with recovery and operational safety before chasing performance tweaks
• Match backup and replication choices to the actual failure scenario
• Prefer least-privilege and simpler rollback paths when answers are close
• Treat RPO, RTO, and operational complexity as primary decision inputs
