Windows Server 2025 — Lesson 3: Security, Virtualization, Availability, and Operations

Learning Objectives

• Apply security baselines, Defender, encryption, privileged access, auditing, and patching
• Review Hyper-V, containers, workload isolation, availability, backup, and recovery options
• Monitor performance, events, services, capacity, reliability, and common operational failures

Detailed Topics

• Apply security baselines: Apply security baselines, Defender, encryption, privileged access, auditing, and patching
• Review Hyper-V: Review Hyper-V, containers, workload isolation, availability, backup, and recovery options
• Monitor performance: Monitor performance, events, services, capacity, reliability, and common operational failures

Guided Demonstration

1. Review the requirement, environment, dependencies, roles, risks, and expected outcome.
2. Demonstrate the relevant configuration, analysis, code, or administration workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, or test evidence.
4. Compare the observed result with the stated acceptance criteria.

Hands-On Activity

Secure and troubleshoot a server workload using event and performance evidence.

• Document assumptions and the planned sequence before making changes.
• Complete the activity and preserve evidence of normal and exception behavior.
• Record issues, corrective actions, and reusable operational or development notes.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, permissions, data, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, support ownership, and user or business impact.

Validation Checklist

• The requirement and expected outcome are clear.
• The selected configuration, design, query, code, or process is documented.
• Normal, boundary, failure, security, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply Security, Virtualization, Availability, and Operations in a realistic scenario and validate the result with documented evidence.
