OCI Architect Professional 1Z0-997-26 Practice Tests

This course contains the use of artificial intelligence.

Knowing the names of OCI services is only the start. Architecture questions ask you to choose a design under competing constraints: how much data can be lost, what must survive a regional failure, which permission is actually missing, and whether a deployment or database change preserves the business outcome.

This English practice course helps you work through those decisions for Oracle Cloud Infrastructure Architect Professional, exam 1Z0-997-26. Each question includes an answer explanation, feedback for every option, and a focused study tip. The scenarios ask you to use the stated requirements rather than select a service merely because its name sounds relevant.

What is included

• 260 focused practice questions in four sets of 65: build your reasoning across resilience, cloud-native delivery, security, databases, and observability.
• Two distinct mixed-domain mocks, each with 50 questions and a 90-minute timer: practice switching between architecture decisions under the published exam length and time limit.
• 360 questions in six tests overall: single-answer questions with shuffled answer positions and explanations for both correct and incorrect choices.

The two mocks together follow the published domain weights: high availability and disaster recovery 15%, cloud-native solutions 20%, security 25%, database solutions 20%, and observability 20%. Individual 50-question mocks use complementary rounding. This is an author-designed distribution, not a claim to reproduce Oracle's actual examination questions or unpublished subtopic quotas.

Learn to separate similar-looking decisions

Practice covers Full Stack DR sequencing and readiness; OKE, OCIR, Functions, Container Instances, and Resource Manager; layered access, Bastion, ZPR, Network Firewall, WAF, Certificates, KMS, and Organizations; Base Database, Autonomous AI Database, Recovery Service, globally distributed databases, and OCI Cache; and Monitoring, Logging, Audit, Connector Hub, and search workflows.

For example, a healthy replica does not automatically prove application recovery, a successful build does not prove release readiness, and key rotation does not automatically remove historical decryption dependencies. The explanations identify the deciding condition and show why another plausible action would leave the stated requirement unmet.

Suggested study approach

Complete the focused sets first, explain your choice before reading the feedback, and revisit the relevant official documentation for each missed concept. Then attempt each mock in one sitting. Review incorrect answers and uncertain correct answers alike. The course uses an 80% study target to encourage further revision; Oracle's published passing percentage is 68%, and practice scores do not predict an official result.

This is independent preparation by BrightRung Learning, not an Oracle course, certification award, or endorsement. Questions are original learning scenarios rather than actual exam questions or exam dumps. This is a practice-test course, without video lessons, supplied cloud accounts, or hands-on labs. AI tools supported question drafting and the cover background; the content was read and revised during production. Passing the certification exam is not guaranteed.
