SQL Server 2016 Admin: High Availability and Performance Tuning — Lesson 3: Performance Monitoring, Indexing, Query Tuning, Locks, and Waits

Topics Covered

• Test failover, recovery, quorum, synchronization, and application continuity
• Monitor waits, resource usage, blocking, deadlocks, and expensive queries
• Design and maintain indexes and statistics for workload requirements
• Security, reliability, performance, support, and operational controls
• Common failure patterns, diagnostic evidence, and root-cause analysis
• Corrective actions, rollback considerations, and reusable runbook updates

Guided Practice Steps

1. Translate the lesson requirement into a clear SQL Server 2016 Admin: High Availability and Performance Tuning implementation or analysis objective.
2. Document assumptions, selected tools or features, dependencies, risks, and expected results.
3. Perform the guided task, capture evidence, and compare the result with the acceptance criteria.
4. Record issues, corrective actions, and a reusable operational or development note.

Practical Activity

Analyze a performance incident using waits, plans, indexes, and blocking evidence.

• Define the scenario, inputs, constraints, and expected outcome.
• Complete the activity and preserve screenshots, outputs, logs, code, or decision evidence.
• Review the result, identify gaps, and document corrective or improvement actions.

Validation Checklist

• The stated requirement and expected outcome are clear.
• Configuration, code, data, or design decisions are documented.
• Normal, boundary, failure, security, and operational considerations are reviewed.
• Evidence supports the conclusion and the next action is prioritized.

Lesson Outcome

Learners can explain and apply Performance Monitoring, Indexing, Query Tuning, Locks, and Waits within a realistic SQL Server 2016 Admin: High Availability and Performance Tuning scenario and support the result with validation evidence.
