Oracle Cloud Infrastructure 2025 Architect Associate Sample Questions (Q47-Q52):

NEW QUESTION # 47
A financial firm is designing an application architecture for its online trading platform that should have high availability and fault tolerance. What should the architect do to avoid any costly service disruptions and ensure data durability?

A. Create a lifecycle policy to regularly send data from the Standard to Archive storage.
B. Create a new Object Storage bucket in another region and configure recycle policy to move data every 5 days.
C. Create a replication policy to send data to a different bucket in another OCI region.
D. Copy the Object Storage bucket to a block volume.

Answer: C

Explanation:
For an online trading platform requiring high availability and fault tolerance, it's critical to ensure data durability and avoid any costly service disruptions. In Oracle Cloud Infrastructure (OCI), Object Storage is often used to store critical data, such as transaction logs or user data, due to its scalability, durability, and reliability.
Option B is the most suitable approach for ensuring data durability and availability across regions. Here's why:
Cross-Region Replication (CRR): OCI offers a feature called Cross-Region Replication for Object Storage. This feature allows you to automatically and asynchronously replicate objects in a bucket from one OCI region to another. This setup ensures that even if one region experiences a failure, the data is still available in another region, thereby meeting the requirements for high availability and fault tolerance.
Data Durability: By replicating data to another region, you protect against regional outages. OCI guarantees 99.95% availability for replicated data, which is critical for a financial firm's trading platform where data consistency and durability are paramount.
Disaster Recovery: With data replicated in another region, the trading platform can quickly switch to using the data in the secondary region in case of a disaster in the primary region. This setup significantly reduces recovery time objectives (RTO) and ensures business continuity.
Reference:
Oracle Cloud Infrastructure Documentation: Cross-Region Replication for Object Storage Oracle Whitepaper: High Availability and Disaster Recovery in Oracle Cloud Infrastructure Explanation of Incorrect Options:
Option A: Creating a new Object Storage bucket in another region and configuring a recycle policy to move data every 5 days does not provide real-time data availability or the fault tolerance required for a financial application. Recycle policies are intended for managing the lifecycle of data, not for high availability or disaster recovery.
Option C: While lifecycle policies are useful for moving less frequently accessed data to a more cost-effective storage tier (e.g., from Standard to Archive), they do not address cross-region redundancy or real-time availability, which are critical for this use case.
Option D: Copying an Object Storage bucket to a block volume is not a recommended practice for ensuring data durability and fault tolerance. Block volumes are used for persistent storage attached to compute instances, and copying object storage data to block volumes does not achieve the same level of redundancy and cross-region availability as replication policies.
Thus, Option B is the correct and most efficient method for ensuring high availability and fault tolerance in this scenario.

NEW QUESTION # 48
You want to protect your VM instance from low-level threats, such as rootkits and bootkits. What should you do?

A. Create a shielded instance.
B. Create a burstable instance.
C. Use Vulnerability Scanning Service.
D. Use in-transit encryption.

Answer: A

Explanation:
To protect your VM instance from low-level threats, such as rootkits and bootkits, you should create a shielded instance in Oracle Cloud Infrastructure (OCI). Shielded instances are designed to provide enhanced security features, including:
Secure Boot: Ensures that the instance boots only with trusted software.
Measured Boot: Records boot metrics, allowing verification that the instance has not been tampered with.
Trusted Platform Module (TPM): Provides additional security through cryptographic functions.
These features help protect against low-level threats that could compromise the integrity of the instance at boot time.

Oracle Cloud Infrastructure Documentation: Shielded Instances

NEW QUESTION # 49
Which is NOT a valid action within the Oracle Cloud Infrastructure (OCI) Block Volume service?

A. Expanding an existing volume in place with offline resizing.
B. Attaching a block volume to an instance in a different availability domain.
C. Restoring from a volume backup to a larger volume.
D. Cloning an existing volume to a new, larger volume.

Answer: B

Explanation:
In Oracle Cloud Infrastructure (OCI), block volumes are designed to be highly flexible and can be used in various ways:
A . Restoring from a volume backup to a larger volume: This is supported and allows for resizing during the restoration process.
B . Cloning an existing volume to a new, larger volume: You can clone a block volume and specify a larger size for the new volume.
C . Expanding an existing volume in place with offline resizing: OCI allows you to increase the size of an existing block volume without needing to take it offline.
Option D is NOT valid because block volumes can only be attached to compute instances within the same availability domain. Cross-availability domain attachment of block volumes is not supported directly.

Oracle Cloud Infrastructure Documentation: Block Volume Overview

NEW QUESTION # 50
Which is NOT a necessary step to complete this setup for instance principals?

A. Generate Auth Tokens to enable instances in the dynamic group to authenticate with APIs.
B. Create a dynamic group with matching rules to specify which instances can make API calls against services.
C. Deploy the application and the SDK to all the instances that belong to the dynamic group.
D. Create a policy granting permissions to the dynamic group to access services in your compartment or tenancy.

Answer: A

Explanation:
Instance principals in OCI allow compute instances to directly make API calls against OCI services without requiring a user account. To set up instance principals, the following steps are necessary:
A . Deploy the application and SDK: The application running on the instances must use the OCI SDK or CLI to make API calls.
B . Create a dynamic group: Define a dynamic group with matching rules to identify which instances can use the API permissions.
C . Create a policy: Write an IAM policy that grants the dynamic group the necessary permissions to access services.
Option D is NOT necessary because instances in a dynamic group use instance principals to authenticate and do not require Auth Tokens, which are used for user authentication with APIs.

Oracle Cloud Infrastructure Documentation: Using Instance Principals

NEW QUESTION # 51
Which statement is true about File System Replication in Oracle Cloud Infrastructure (OCI)?

A. Only a file system that has been exported can be used as a target file system.
B. You can replicate the data in one file system to another file system in the same region or a different region.
C. You can replicate the data in one file system to another file system only in the same region.
D. You cannot specify a replication interval when you create the replication resource.

Answer: B

Explanation:
File System Replication in Oracle Cloud Infrastructure (OCI) allows you to replicate data from one file system to another either within the same region or across different regions. This capability is particularly useful for disaster recovery, data protection, and global data distribution scenarios.
Cross-Region Replication: The replication feature enables you to create a copy of your file system in a different region, ensuring that your data is available even in the event of a regional failure.
Same-Region Replication: You also have the option to replicate data within the same region, which can be useful for scenarios such as high availability and local backups.
