What is a best practice when planning and instituting access controls for your Autonomous Dedicated...

When designing access controls for an Autonomous Dedicated environment, Oracle recommends redundancy and separation for security and manageability:

Correct Answer (D): “Create at least 2 of each resource” (subnets, compartments, user groups) is a best practice:

Subnets: Using at least two subnets (e.g., one public, one private) enhances security by segregating traffic and provides failover options if one subnet encounters issues.

Compartments: Multiple compartments allow logical separation (e.g., dev, test, prod), simplifying access control and resource management.

User Groups: At least two groups (e.g., admins, developers) streamline permission assignments and reduce the risk of over-privileging users.

Incorrect Options:

A: OCI allows multiple subnets and compartments; restricting to one limits flexibility and security.

B: There’s no such limitation; multiple resources are supported and encouraged.
