Oracle Cloud Infrastructure Foundations — Lesson 4: Security, High Availability, Disaster Recovery, Monitoring, and Cost

Learning Objectives

• Explain the purpose and operating context of Cloud Guard, Security Zones, Vault, encryption, WAF, and bastion awareness.
• Apply redundancy, backups, availability, RTO, RPO, and disaster-recovery concepts and Monitoring, Logging, alarms, events, audit, and operational visibility in a controlled environment.
• Validate outcomes and troubleshoot risks involving pricing, cost estimation, support, architecture scenarios, and exam review.

Detailed Topics

• Cloud Guard, Security Zones, Vault, encryption, WAF, and bastion awareness
• redundancy, backups, availability, RTO, RPO, and disaster-recovery concepts
• Monitoring, Logging, alarms, events, audit, and operational visibility
• pricing, cost estimation, support, architecture scenarios, and exam review

Instructor Demonstration

Demonstrate Cloud Guard, Security Zones, Vault, encryption, WAF, and bastion awareness for a new cloud team selecting basic OCI services for a secure and resilient application; capture the exact configuration, code, command, transaction, query, dashboard, model, schedule, or report evidence that proves the expected result.

Hands-On Exercise

Complete a controlled Oracle Cloud Infrastructure Foundations exercise covering redundancy, backups, availability, RTO, RPO, and disaster-recovery concepts and Monitoring, Logging, alarms, events, audit, and operational visibility; introduce an exception involving pricing, cost estimation, support, architecture scenarios, and exam review, diagnose it from evidence, apply the smallest reversible correction, and rerun acceptance checks.

1. Confirm scope, prerequisites, identities, dependencies, data, risks, and expected outcome.
2. Perform the course-specific configuration, development, administration, analysis, or business-process workflow.
3. Capture commands, settings, records, logs, screenshots, reports, metrics, or test results.
4. Compare the observed result with acceptance criteria and document corrective or preventive action.

Scenario Analysis

• Identify the technical or business decision and the stakeholders affected by it.
• Compare security, performance, reliability, compliance, cost, usability, and support trade-offs.
• Define rollback, recovery, communication, evidence, ownership, and escalation requirements.

Troubleshooting Guidance

Diagnose issues involving Cloud Guard, Security Zones, Vault, encryption, WAF, and bastion awareness, redundancy, backups, availability, RTO, RPO, and disaster-recovery concepts, Monitoring, Logging, alarms, events, audit, and operational visibility, pricing, cost estimation, support, architecture scenarios, and exam review without making an unverified production change. Separate symptoms from causes, gather time-correlated evidence, test a reversible hypothesis, validate the correction, and record recurrence controls.

Validation Checklist

• The requirement, environment, inputs, dependencies, and expected result are documented.
• The result is reproducible and supported by product-specific evidence.
• Normal, boundary, failure, security, performance, and operational conditions are reviewed.
• Exceptions, rollback, ownership, support actions, and the next improvement priority are recorded.

Lesson Outcome

Learners can apply Security, High Availability, Disaster Recovery, Monitoring, and Cost in a realistic Oracle Cloud Infrastructure Foundations scenario and defend the result with documented evidence.
