This course is a practice question bank for Oracle exam 1Z0-1104-26, Oracle Cloud Infrastructure Security Professional. It contains six practice tests — 134 questions in total — covering all six domains of the current exam blueprint.

What's covered:
OCI Security Introduction (shared responsibility model, security design principles), Implementing Identity and Access Management (compartments, policy syntax, Dynamic Groups, Instance and Resource Principals, Tag-based Access Control, MFA), Protecting Infrastructure - Network and Applications (NSGs, Security Lists, Network Firewall, Load Balancers, WAF, Service Gateway, FastConnect), Implementing OS and Workload Protection (Bastion, vulnerability scanning, container image security), Protecting Data (Vault, KMS, Data Safe, Object Storage security), and Detecting, Remediating, and Monitoring OCI Resources (Cloud Guard, Security Zones, Threat Intelligence, OCI Audit).

What makes this different from a typical question dump:
Every single answer option — not just the correct one — has its own explanation. When you get a question wrong, you see exactly why each distractor is wrong and why the correct answer is right.

Here's an actual example from the course:

Question: "Which statement correctly distinguishes Security Zones from Cloud Guard?"

A) Security Zones enforce preventive policy that blocks non-compliant resource creation outright, while Cloud Guard is primarily a detective control — Correct. Security Zones apply enforced policy at the point of resource creation, blocking non-compliant operations before they happen, while Cloud Guard detects and responds after resources already exist.
B) Security Zones and Cloud Guard are two names for the same underlying service — Incorrect. The two are distinct, complementary services with different enforcement models.
C) Cloud Guard prevents resource creation, while Security Zones only reports on problems after the fact — Incorrect. This reverses the actual distinction between the two services.
D) Security Zones can be overridden by a compartment administrator at any time — Incorrect. Security Zone policy is specifically designed to be enforced even against administrators, which is what makes it genuinely preventive.

That's the format for all 134 questions: every option explained, not just the right one.

The six tests are not uniform in size. Tests 1 through 4 build broad coverage across all six domains. Tests 5 and 6 are shorter and more concentrated: Test 5 focuses on Object Storage security mechanics, and Test 6 goes deep on Cloud Guard's detector taxonomy and tag-based governance.

Every question is tagged with its exam domain, so you can score yourself by topic and see exactly where to focus before exam day.

One honest note: Oracle periodically updates exam question counts, duration, and passing thresholds. Please confirm current details on Oracle University's official 1Z0-1104-26 page before scheduling.

Whether you're a cloud security engineer, a DevSecOps practitioner, or moving into an OCI security role, this course gives you a structured, honest way to find out what you know and what you don't — before the exam does.
