Oracle 1Z0-1072-25 Practice Exam Questions & Answers

Oracle Cloud Infrastructure (OCI) File Storage Service offers robust encryption capabilities to ensure data security.

B . Customer-Managed Encryption: Customers can choose to encrypt their data using their own keys stored in the OCI Vault service. This gives customers control over their encryption keys and enhances data security.

D . Oracle-Managed Encryption: By default, all data stored in OCI File Storage is encrypted using Oracle-managed keys. This ensures that data is encrypted at rest without requiring any action from the customer.

Incorrect Statements:

A . Communication is not encrypted via HTTPS when accessing file systems; instead, encryption in transit is typically managed via NFS over TLS.

C . Encryption of communication to a mount target is handled via network configurations, not through export options.

When performing a multipart upload using the Multipart Upload API in Oracle Cloud Infrastructure (OCI) Object Storage, the following points are true:

C . Each part can be as large as 50 GiB: OCI allows each part of a multipart upload to be up to 50 GiB in size. This enables the efficient uploading of large objects in smaller, manageable parts.

D . You can keep adding parts as long as the total number is less than 10,000: The Multipart Upload API supports up to 10,000 parts for a single object. This allows the upload of very large objects by dividing them into multiple parts.

Incorrect Statements:

A . After uploading all parts, you must commit the upload to finalize the multipart upload and combine all parts into a single object.

B . The object must be split into parts before uploading when using the Multipart Upload API.

In OCI, if you choose not to proactively reboot your instance before the scheduled maintenance due date, the system will handle the maintenance automatically to ensure that the instance remains operational.

Reboot-Migration or Rebuild in Place: If you don't reboot the instance yourself, OCI will automatically perform a reboot-migration or rebuild in place for the instance. This ensures that the instance is moved to new hardware or updated without your intervention, maintaining uptime and applying necessary updates or fixes.

Impact on Instance: The exact action taken (reboot-migration or rebuild in place) depends on the type of maintenance required. However, either action will temporarily interrupt the instance, typically involving a reboot, but the instance's data and configuration will be preserved.

In Oracle Cloud Infrastructure (OCI), when you need a full-featured Identity-as-a-Service (IDaaS) solution, the appropriate Identity Domain type to create is Premium.

Premium Identity Domain: This option provides a comprehensive set of identity and access management (IAM) capabilities, including advanced security features, identity governance, and support for enterprise-grade integrations. It supports managing user identities, multifactor authentication, and various other identity services required for a robust IDaaS solution.

Other Options:

External User: This is a limited domain type typically used for managing users who only need access to specific external services.

Free: This domain type offers limited features and is not intended for full-featured enterprise IAM requirements.

Oracle Apps Premium: This is tailored for integrating with Oracle applications but does not offer the broad capabilities of the Premium option.

This documentation explains the various identity domain types and their use cases within OCI.

The following statements about OCI burstable instances are NOT correct:

A . Burstable instances cost less than regular instances: This is incorrect because burstable instances are not necessarily cheaper; the cost depends on the baseline utilization. While they allow for cost efficiency when running at a lower CPU baseline, they can become more expensive if frequently bursting above the baseline.

B . Burstable instances are charged according to the baseline OCPU: This is incorrect because burstable instances are billed based on actual OCPU usage, which includes both baseline and burst usage. If an instance frequently operates above its baseline, the cost will reflect this higher usage.

Correct Concepts:

C . Burstable instances can temporarily use more CPU than their baseline if the average CPU utilization is below the baseline.

D . Baseline utilization is a fraction of each CPU core, which determines the level of consistent performance available without bursting.
