Prepare for the Oracle Cloud Infrastructure Architect Professional certification exam 1Z0-997-26 with 165 original exam-style questions across four timed practice tests. This advanced course helps you evaluate complex requirements, identify architectural tradeoffs, strengthen weak domains, and build confidence before your certification attempt.

WHAT YOU WILL PRACTICE

• Advanced tenancy, compartment, network, connectivity, DNS, load balancing, and hybrid-cloud designs

• Compute, Kubernetes, storage, database, Exadata, Autonomous Database, integration, and migration architectures

• High availability, disaster recovery, backup, replication, business continuity, and operational resilience

• IAM, security zones, encryption, monitoring, logging, governance, compliance, performance, and cost optimization

• Scenario-based questions that require balancing security, reliability, scalability, manageability, and cost

• Certification strategy, time management, domain review, and elimination of close distractors

HOW THE COURSE IS STRUCTURED

Practice Test 1 provides a broad professional-level architecture readiness check.

Practice Test 2 focuses on advanced networking, hybrid connectivity, compute, storage, databases, and migration.

Practice Test 3 covers resilience, DR, security, governance, observability, performance, and complex architecture scenarios.

Practice Test 4 is a final mixed certification review designed to simulate exam pressure and confirm your readiness.

Every question includes a clear explanation of the strongest answer and guidance on why the alternatives are less appropriate.
