Oracle Cloud Infrastructure 2025 Architect Associate Sample Questions (Q41-Q46):

NEW QUESTION # 41
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 restore only one volume from a manual block volume backup.
B. You can restore a volume from any full volume backup but not from an incremental backup.
C. You can only restore a volume to the same availability domain in which the original block volume resides.
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 # 42
Which OCI service would you use to apply kernel security updates to all instances?

A. Container Registry
B. Artifact Registry
C. OS Management Service
D. Data Safe

Answer: C

Explanation:
The OS Management Service in Oracle Cloud Infrastructure (OCI) is designed to manage and maintain the operating systems of your compute instances. This service allows you to apply kernel security updates, manage package installations, and monitor the status of updates across all instances in your environment.
Kernel Security Updates: With OS Management Service, you can automate and schedule kernel updates, ensuring that all instances are up-to-date with the latest security patches. This helps maintain the security and integrity of your infrastructure without needing to manually update each instance.
Other Options:
Container Registry: Used for storing and managing container images, not for applying OS updates.
Data Safe: A service focused on database security, not applicable for OS-level updates.
Artifact Registry: A repository for storing and managing software artifacts, not related to OS management.
Relevant OCI Documentation:
OS Management Service Overview
This documentation provides details on how to use OS Management Service to handle kernel security updates and other OS-level management tasks.

NEW QUESTION # 43
Which components are required for establishing remote peering between two Virtual Cloud Networks (VCNs) in Oracle Cloud Infrastructure (OCI)?

A. Two VCNs with nonoverlapping CIDRS in the same region, a dynamic routing gateway (DRG) attached to each VCN, and a direct connection between the DRGs.
B. Two VCNs with overlapping CIDRS in different regions, a virtual private network (VPN) gateway attached to each VCN, and a direct connection between the VPN gateways.
C. A single VCN with nonoverlapping CIDRS in each region, a dynamic routing gateway (DRG) attached to each VCN, and a direct connection between the DRGS.
D. Two VCNs with nonoverlapping CIDRS in different regions, a dynamic routing gateway (DRG) attached to each VCN, a remote peering connection (RPC) on each DRG, and a connection established between the RPCs.

Answer: D

Explanation:
Remote peering in Oracle Cloud Infrastructure allows two VCNs in different regions to communicate securely. To establish remote peering, the following components are required:
Two VCNs with Nonoverlapping CIDRs:
The CIDR blocks of the two VCNs must not overlap. This is crucial to avoid routing conflicts and ensure that traffic is correctly routed between the VCNs.
Dynamic Routing Gateway (DRG) Attached to Each VCN:
A DRG is a virtual router that provides a path for traffic between the VCN and networks outside the VCN, such as other VCNs via remote peering, on-premises networks, or other cloud services. Each VCN needs its own DRG.
Remote Peering Connection (RPC):
An RPC is a specialized connection on the DRG used specifically for remote peering. You need to create an RPC on each DRG associated with the VCNs you wish to peer.
Connection Between RPCs:
Finally, a connection must be established between the RPCs of the two DRGs. This connection facilitates the secure and private exchange of traffic between the VCNs over Oracle's backbone network.
Incorrect Options:
Option A involves a single VCN, which does not fulfill the requirement of remote peering between two VCNs.
Option B involves overlapping CIDRs and VPN gateways, which are incorrect for remote peering.
Option C suggests peering within the same region, which would be considered local peering rather than remote peering.
Relevant OCI Documentation:
OCI Remote VCN Peering
Dynamic Routing Gateway (DRG) Overview
These resources provide a detailed guide on configuring remote peering in OCI, ensuring secure and effective communication between VCNs across regions.

NEW QUESTION # 44
How will moving a database instance to a different compartment impact user access?

A. Compartments are not covered by IAM policies.
B. Compartments prevent resource movement.
C. IAM policies are not tied to compartments.
D. Access will be revoked for all users.

Answer: D

Explanation:
In Oracle Cloud Infrastructure (OCI), when you move a database instance to a different compartment, the following impact on user access occurs:
Impact of Moving Resources: When you move a resource, like a database instance, to a different compartment, the IAM policies that grant access to that resource in the original compartment no longer apply. This effectively revokes access for users or groups unless equivalent policies are in place in the new compartment.
Restoring Access: To restore access, you would need to create new IAM policies in the destination compartment that grant the necessary permissions to the users or groups who need access.
Relevant OCI Documentation:
Managing Compartments
Moving Resources
These resources provide detailed steps on how compartment changes impact resource access and management.

NEW QUESTION # 45
What would be the total meteredBytes shown by the File Storage service after the hourly update cycle is complete when you overwrite 0.5 GB of a 1 GB file?

A. 1 GB
B. 0.5 GB
C. 2.5 GB
D. 1.5 GB

Answer: D

Explanation:
In Oracle Cloud Infrastructure (OCI) File Storage, when you overwrite a portion of a file, the service does not immediately reclaim the space occupied by the previous version of the file. The total meteredBytes reflects both the original data and the new data written.
Scenario Explanation: You start with a 1 GB file. When you overwrite 0.5 GB of this file, the file system retains both the 0.5 GB of the original file and the new 0.5 GB you wrote.
Calculation: The original 1 GB file contributes 1 GB to meteredBytes. When 0.5 GB is overwritten, the total usage becomes 1.5 GB (1 GB original + 0.5 GB new).
Thus, after the hourly update cycle, the total meteredBytes shown by the File Storage service will be 1.5 GB.
