1Z0-1085-26 Core Oci Services Practice Question
An organization has strict compliance requirements to ensure that all data stored in OCI Object Storage buckets is encrypted using a custom encryption key managed entirely by the customer, rather than Oracle-managed keys. How can this be achieved?
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
✓
Use OCI Vault to create and manage Customer-Managed Keys (CMK) for encrypting the Object Storage bucket.
OCI Object Storage supports Customer-Managed Keys (CMK) using OCI Vault, allowing customers to control the master encryption keys used to encrypt their data.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable bucket versioning and assign an IAM administrator password.
Why it's wrong here
Versioning and passwords do not provide cryptographic key management.
- ✗
Attach an Internet Gateway configured with SSL certificates.
Why it's wrong here
Internet Gateways handle network transit encryption, not storage at-rest encryption keys.
- ✓
Use OCI Vault to create and manage Customer-Managed Keys (CMK) for encrypting the Object Storage bucket.
Why this is correct
OCI Vault enables using customer-managed encryption keys for Object Storage buckets.
- ✗
Encrypt the data manually using local scripts before uploading to Object Storage.
Why it's wrong here
While client-side encryption is possible, OCI natively supports customer-managed keys via OCI Vault.
