질문 # 52
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 replication policy to send data to a different bucket in another OCI region.
B. Copy the Object Storage bucket to a block volume.
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.

정답：A

설명：
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.

질문 # 53
Which is NOT a necessary step to complete this setup for instance principals?

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

정답：B

설명：
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.

질문 # 54
Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OCI) File System snapshots?

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

정답：A

설명：
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.

질문 # 55
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 a volume from any full volume backup but not from an incremental backup.
B. You can restore only one volume from a manual block volume backup.
C. You can restore a block volume backup to a larger volume size.
D. You can only restore a volume to the same availability domain in which the original block volume resides.

정답：C

설명：
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.

질문 # 56
Which statement accurately describes ephemeral principals?

A. Ephemeral principals are another term for dynamic groups.
B. Ephemeral principals are temporary credentials granted to resources.
C. Ephemeral principals represent long-lived service accounts.
D. Ephemeral principals are user accounts with limited lifespans.

정답：B

설명：
Ephemeral principals in Oracle Cloud Infrastructure (OCI) refer to temporary security credentials granted to resources, such as compute instances, to enable them to interact with OCI services securely. These credentials have a limited lifespan and are typically used in situations where resources need to authenticate temporarily without the need for long-lived credentials.
Use Case: Ephemeral principals are often used for instance principals, allowing compute instances to make API calls without the need to manage long-term keys or credentials.
