Networking with Windows Server (55349AC) — Lesson 4: Network Security and Troubleshooting

Learning Objectives

• Apply Windows Firewall, IPsec, access controls, monitoring, and secure administration
• Diagnose DHCP, DNS, routing, firewall, VPN, latency, and service failures
• Create operational baselines, recovery procedures, and documentation

Detailed Topics

• Apply Windows Firewall: Apply Windows Firewall, IPsec, access controls, monitoring, and secure administration
• Diagnose DHCP: Diagnose DHCP, DNS, routing, firewall, VPN, latency, and service failures
• Create operational baselines: Create operational baselines, recovery procedures, and documentation

Guided Demonstration

1. Review the requirement, users, data, dependencies, permissions, risks, and expected result.
2. Demonstrate the relevant configuration, development, administration, analysis, or collaboration workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, test results, and other useful evidence.
4. Compare the observed result with acceptance criteria and explain any corrective action.

Hands-On Activity

Resolve a Windows Server networking incident and complete an operations checklist.

• Document assumptions, prerequisites, and the planned sequence before starting.
• Complete the activity and preserve evidence of normal, boundary, and failure behavior.
• Record issues, corrective actions, reusable notes, and the next improvement priority.

Scenario Analysis

• Identify the business or technical decision that must be made.
• Compare valid implementation approaches and their trade-offs.
• Consider security, privacy, accessibility, performance, support, and operational impact.

Troubleshooting Focus

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

Validation Checklist

• The requirement, scope, inputs, and expected outcome are clear.
• The selected design or configuration is documented and follows approved standards.
• Normal, boundary, failure, security, accessibility, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply Network Security and Troubleshooting in a realistic scenario and validate the result with documented evidence.
