Oracle Cloud Infrastructure 2025 Architect Associate Sample Questions (Q51-Q56):

NEW QUESTION # 51
Which statement is TRUE about restoring a volume from a block volume backup in the Oracle Cloud Infrastructure (OCI) Block Volume service?

A. You can only restore a volume to the same availability domain in which the original block volume resides.
B. You can restore a volume from any full volume backup but not from an incremental backup.
C. You can restore only one volume from a manual block volume backup.
D. You can restore a block volume backup to a larger volume size.

Answer: D

Explanation:
Restoring a block volume from a backup in OCI provides flexibility and options for scaling and recovery:
Restoring to a Larger Volume Size: When restoring a block volume from a backup, you have the option to restore it to a volume that is larger than the original. This is particularly useful if you anticipate needing more storage capacity after the restore.
Full and Incremental Backups: OCI supports both full and incremental backups. You can restore from any backup type, which makes it possible to restore data efficiently depending on the backup strategy used.
Multiple Restores: Multiple volumes can be restored from a single backup, providing flexibility in disaster recovery scenarios.
Availability Domain: The restored volume can be created in any availability domain within the same region, not necessarily the same one where the original volume was located.
Relevant OCI Documentation:
Block Volume Service Overview
Restoring a Block Volume
These references explain the process and options available for restoring block volumes from backups.

NEW QUESTION # 52
Which TWO statements are NOT correct regarding the Oracle Cloud Infrastructure (OCI) burstable instances?

A. Baseline utilization is a fraction of each CPU core.
B. Burstable instances cost less than regular instances.
C. If the instance's average CPU utilization is below the baseline, it can burst above the baseline.
D. Burstable instances are charged according to the baseline OCPU.

Answer: B,D

Explanation:
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.

Oracle Cloud Infrastructure Documentation: Burstable Instances

NEW QUESTION # 53
Which compute capacity type would you select to meet these requirements?

A. Capacity reservation
B. Dedicated host
C. Preemptible capacity
D. On-demand capacity

Answer: D

Explanation:
On-demand capacity is the compute capacity type in Oracle Cloud Infrastructure (OCI) that allows you to provision and use compute instances whenever needed, without any long-term commitment. This flexibility is ideal for various workloads, including development, testing, and production environments, where immediate availability and scalability are crucial.
Key Points:
On-Demand Capacity: On-demand compute instances provide users with the flexibility to spin up instances as required and only pay for the time the instances are running. This model is most suitable for workloads with unpredictable usage patterns or short-term requirements.
Flexibility and Scalability: With on-demand capacity, you can quickly scale your resources up or down based on your application's needs, ensuring that you only pay for the resources you actually use.
No Commitment: Unlike reserved capacity, on-demand capacity does not require any long-term commitment or upfront payment, making it an attractive option for organizations looking to avoid capital expenditures.
Reference:
Oracle Cloud Infrastructure Documentation: OCI Compute Pricing
Oracle Cloud Infrastructure Documentation: Compute Instance Lifecycle
Explanation of Incorrect Options:
A . Capacity reservation: This option allows you to reserve capacity in advance, ensuring that resources are available when needed. It's ideal for predictable workloads but may not be as cost-effective for fluctuating demands.
B . Preemptible capacity: Preemptible instances are a lower-cost option where instances can be terminated by OCI if resources are needed elsewhere. This is suitable for non-critical workloads that can tolerate interruptions.
D . Dedicated host: Dedicated hosts provide physical servers for your exclusive use, offering isolation and predictable performance. This option is more suitable for workloads requiring dedicated resources or compliance needs.
Thus, Option C: On-demand capacity is the correct choice for most general-purpose workloads needing flexibility and immediate availability without long-term commitment.

NEW QUESTION # 54
Which image option allows you to create identical instances with minimal effort?

A. Use Oracle-provided images
B. Create a custom image
C. Select an image from the OCI Marketplace
D. Bring your own image

Answer: B

Explanation:
When you need to create identical instances with minimal effort, creating a custom image is the best option.
Custom Images: A custom image captures the exact configuration of an instance, including the OS, software, configurations, and data. By using a custom image, you can easily replicate the same setup across multiple instances, ensuring consistency and reducing the need for manual configuration each time.
Other Options:
Bring Your Own Image: This allows you to import your custom OS image into OCI, but it's more suited for cases where you are migrating from another environment.
Select an Image from the OCI Marketplace: This provides pre-configured images from Oracle or third parties, but they may require additional setup to match your specific requirements.
Use Oracle-Provided Images: These are basic images provided by Oracle, which may not include the specific customizations you need.
Relevant OCI Documentation:
Custom Images Overview
This resource explains how to create and use custom images for quickly deploying identical instances.

NEW QUESTION # 55
Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OCI) File System snapshots?

A. Snapshots are a consistent, point-in-time view of your file systems.
B. Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot consumes more storage.
C. Snapshots are accessible under the root directory of the file system at .snapshot/name.
D. Before you can clone a file system, at least one snapshot must exist for the file system.

Answer: B

Explanation:
In OCI File Storage, snapshots are point-in-time, read-only copies of a file system that do not immediately consume additional storage beyond the space needed to track changes.
Incorrect Statement: The statement that a new snapshot consumes more storage even if nothing has changed is incorrect. Snapshots are space-efficient; they only consume additional storage as changes are made to the file system after the snapshot is taken. If no changes are made between snapshots, the storage consumption remains minimal.
Correct Statements:
B . Before cloning a file system, at least one snapshot must exist, as the clone operation relies on this snapshot to create a copy.
C . Snapshots are accessible under the .snapshot directory, allowing users to view and restore files from specific snapshots.
D . Snapshots provide a consistent, point-in-time view of the file system, ensuring data integrity.
