Oracle Cloud Infrastructure 2025 Architect Associate Sample Questions (Q31-Q36):

NEW QUESTION # 31
Why was SSH still possible after port 22 was removed from the Security Lists?

A. The VCN where that compute instance resides still has an Internet Gateway.
B. The VNIC of that compute instance is attached to a Network Security Group (NSG).
C. The VCN where that compute instance resides still has a route rule.
D. The VNIC of that compute instance is attached to a Cluster Network.

Answer: B

Explanation:
Even after removing port 22 from the Security Lists, SSH was still possible because the Virtual Network Interface Card (VNIC) of the compute instance is attached to a Network Security Group (NSG).
NSGs: NSGs provide a more flexible and granular way to manage security rules compared to Security Lists. They allow you to apply security rules directly to VNICs associated with resources such as compute instances. If an NSG allows traffic on port 22, SSH will still be possible, regardless of the Security List settings.

NEW QUESTION # 32
Which THREE protocols are supported by the Oracle Cloud Infrastructure (OCI) private Network Load Balancers?

A. TCP
B. BGP
C. iSCSI
D. ICMP
E. UDP
F. HTTP

Answer: A,E,F

Explanation:
The OCI Private Network Load Balancer supports multiple protocols for managing traffic efficiently across your instances within a private subnet. Specifically, it supports:
UDP (User Datagram Protocol): Commonly used for applications that require fast, connectionless communication, such as video streaming or DNS services.
TCP (Transmission Control Protocol): A reliable, connection-oriented protocol, widely used for web traffic and other applications requiring data integrity.
HTTP (Hypertext Transfer Protocol): Frequently used for web traffic, it is an application-layer protocol built on top of TCP and enables communication between web browsers and servers.
The combination of these protocols allows the OCI Network Load Balancer to manage diverse workloads, including web services and real-time applications.

NEW QUESTION # 33
By default, OCI IAM policies follow the principle of least privilege. What does this principle mean in the context of policy creation?

A. Policies should grant all possible permissions to simplify access control.
B. Policies should be written in a complex and technical manner to enhance security.
C. Policies should provide only the minimum set of permissions required for users to perform their tasks effectively.
D. Policies should be identical for all users within a tenancy.

Answer: C

Explanation:
The principle of least privilege is a security best practice that dictates that users should only be granted the minimum set of permissions necessary to perform their tasks. This principle helps to minimize the risk of accidental or malicious actions that could compromise security.
IAM Policies in OCI: When creating IAM policies in OCI, you should carefully evaluate the required permissions and only grant those that are absolutely necessary for the users or groups to perform their specific roles. This helps to reduce the attack surface and prevent unauthorized access to sensitive resources.

NEW QUESTION # 34
How will moving a database instance to a different compartment impact user access?

A. IAM policies are not tied to compartments.
B. Compartments prevent resource movement.
C. Compartments are not covered by IAM policies.
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:

Moving Resources
These resources provide detailed steps on how compartment changes impact resource access and management.

NEW QUESTION # 35
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 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. Create a lifecycle policy to regularly send data from the Standard to Archive storage.

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.
