Course coverage
What This 1Z0-1072-25 Page Covers
This 1Z0-1072-25 page is organized into 10 clear sections so learners can revise with structure instead of treating OCI architecture as one large block. It covers identity, access control, governance, storage, compute, app hosting, networking, hybrid connectivity, monitoring, backup, and recovery in a more practical and manageable way.
Move between OCI foundations, IAM, networking, compute, storage, and reliability during revision so the services connect more naturally and architectural decisions become easier to interpret.
