Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation

Create an Autonomous Exadata Infrastructure resource in your compartment and virtual cloud network.
Before provisioning an Autonomous Database on Dedicated Exadata Infrastructure, you must first create an Autonomous Exadata Infrastructure resource within a specific availability domain or fault domains, which reserves the underlying compute and storage resources.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Contact Oracle Support to manually allocate physical rack boundaries in your tenancy region.
Why it's wrong here
Provisioning is handled via the OCI console or APIs without manual Oracle Support intervention.
- ✓
Create an Autonomous Exadata Infrastructure resource in your compartment and virtual cloud network.
Why this is correct
An Autonomous Exadata Infrastructure resource must be created first to define the Exadata rack allocation within your VCN and subnet before creating Autonomous Container Databases and Autonomous Databases.
- ✗
Create a Pluggable Database (PDB) manually via SQL*Plus on an existing multitenant container database.
Why it's wrong here
Autonomous Databases are managed fully by Oracle; manual PDB creation via SQL*Plus is not supported on Dedicated infrastructure.
- ✗
Provision a standard Exadata Cloud Service cluster using the Database management service console.
Why it's wrong here
Autonomous Database on Dedicated Infrastructure does not use standard Exadata Cloud Service cluster provisioning workflows.
