Oracle Cloud Infrastructure 2025 Architect Associate Sample Questions (Q34-Q39):

NEW QUESTION # 34
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. Copy the Object Storage bucket to a block volume.
B. Create a replication policy to send data to a different bucket in another OCI region.
C. Create a lifecycle policy to regularly send data from the Standard to Archive storage.
D. Create a new Object Storage bucket in another region and configure recycle policy to move data every 5 days.

Answer: B

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 # 35
Which authentication option should you use to ensure third-party APIs communicate with OCI resources?

A. SSH Key Pair with 2048-bit algorithm
B. Auth Tokens
C. API Signing Key
D. OCI Username and Password

Answer: C

Explanation:
When ensuring that third-party APIs communicate securely with OCI resources, the appropriate authentication option is API Signing Key.
API Signing Key: This method uses an RSA key pair to authenticate and sign API requests. The API signing key provides a secure and reliable way to ensure that the API requests to OCI are coming from an authorized source. It is commonly used for programmatic access to OCI services.
Other Options:
SSH Key Pair: Primarily used for secure shell access to compute instances, not for API authentication.
Auth Tokens: Typically used for authentication in environments where APIs don't support the API Signing Key, such as OCI CLI or SDKs.
OCI Username and Password: Generally used for the Console login, not for securing API communications.
Relevant OCI Documentation:
API Signing Key Authentication
This documentation provides details on using API Signing Keys for secure API communication in OCI.

NEW QUESTION # 36
How would you allow access to FSS for a DB System with read-only permissions?

A. Create an instance principal for the DB System.
B. Modify the security list to allow stateless ingress rules.
C. Modify the security list to allow stateful ingress rules.
D. Create an NFS export option that allows READ_ONLY access.

Answer: D

Explanation:
To allow access to Oracle Cloud Infrastructure (OCI) File Storage Service (FSS) for a Database (DB) System with read-only permissions, you should create an NFS export option that specifies READ_ONLY access.
NFS Export Options: These options define the access permissions (read/write or read-only) for clients connecting to the file system. By setting the export option to READ_ONLY, you ensure that the DB System can only read from the FSS and cannot modify or delete files.

Oracle Cloud Infrastructure Documentation: File Storage Service Export Options

NEW QUESTION # 37
Which statement is true about File System Replication in Oracle Cloud Infrastructure (OCI)?

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

Answer: A

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.

NEW QUESTION # 38
Which TWO options will accomplish a fully redundant connection from an on-premises data center to a Virtual Cloud Network (VCN) in the us-ashburn-1 region?

A. Configure one FastConnect virtual circuit to the us-ashburn-1 region and a Site-to-Site VPN to the us-ashburn-1 region.
B. Configure one FastConnect virtual circuit to the us-ashburn-1 region and the second FastConnect virtual circuit to the us-phoenix-1 region.
C. Configure two FastConnect virtual circuits to the us-ashburn-1 region and terminate them in diverse hardware on-premises.
D. Configure a Site-to-Site VPN from a single on-premises CPE.

Answer: A,C

Explanation:
For a fully redundant connection from an on-premises data center to a VCN in the OCI us-ashburn-1 region, it is important to ensure high availability and fault tolerance. Here's how each option contributes to redundancy:
Option B: Two FastConnect Virtual Circuits:
FastConnect provides a dedicated, private connection with higher bandwidth and more consistent performance compared to a VPN. To achieve redundancy, you can configure two FastConnect circuits in the same region (us-ashburn-1), each terminated on diverse hardware on-premises. This setup ensures that even if one circuit or its associated hardware fails, the other circuit can maintain the connection. This ensures no single point of failure in the connectivity to OCI. Thus, option B is correct.
Option D: FastConnect and Site-to-Site VPN:
Another approach to redundancy is to have a mix of connection types. By setting up one FastConnect circuit and one Site-to-Site VPN, both terminating in the same region (us-ashburn-1), you create a diverse connection path. If the FastConnect connection fails, traffic can automatically route through the VPN connection, maintaining connectivity. This setup adds an extra layer of redundancy, making option D correct as well.
Incorrect Options:
Option A: Only configuring a Site-to-Site VPN from a single on-premises CPE does not provide redundancy because it involves just one connection path. If that connection or the CPE fails, there would be no fallback.
Option C: Configuring FastConnect circuits to different regions (us-ashburn-1 and us-phoenix-1) does not provide redundancy within a single region but rather across regions, which is not required for regional redundancy.
Relevant OCI Documentation:

These references offer more detailed information on setting up redundant connections and the benefits of each connection type within OCI.
