- A. Object Versioning is enabled at the namespace level.
- B. Object Storage resources can be shared across tenancies.
- C. Immutable option for data stored in Object Storage can be set via retention rules.
- D. Object lifecycle rules can be used to archive or delete objects.
Answer: B
Explanation:
Oracle Cloud Infrastructure (OCI) Object Storage is a scalable, highly durable service that allows you to store any type of data in a secure and cost-effective manner. The correct and incorrect statements regarding OCI Object Storage are as follows:
A . Immutable Option: You can indeed set an immutable option for data in Object Storage using retention rules. This feature ensures that once data is written, it cannot be modified or deleted until the retention period expires, making it ideal for regulatory compliance.
C . Object Lifecycle Rules: Object lifecycle policies allow you to automate the archiving or deletion of objects based on their age or other criteria, helping manage storage costs and data retention efficiently.
D . Object Versioning: Versioning is enabled at the bucket level, not the namespace level. However, once enabled for a bucket, it helps retain, retrieve, and restore every version of every object stored in that bucket.
B . Object Storage Sharing Across Tenancies: This statement is not true. OCI Object Storage buckets and objects are specific to a tenancy and cannot be shared across different tenancies directly. Access to Object Storage resources is controlled within a single tenancy through IAM policies.

NEW QUESTION # 24
Which policy would you write to provide admin access to all three of your existing admin groups for a shared Test compartment?
- A. Allow dynamic-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
- B. Allow all-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
- C. Allow group any-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
- D. Allow any-user to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
Answer: B
Explanation:
In Oracle Cloud Infrastructure (OCI), policies are written to define permissions for user groups. The correct policy to provide admin access to all three existing admin groups in a shared compartment (in this case, the "Test" compartment) would be:
"Allow all-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'".
"Allow all-group": Grants access to all groups.
"to manage all-resources": Specifies full access permissions (manage includes all CRUD operations).
"in compartment Test": Limits the scope of the policy to the "Test" compartment.
"where request.principal.group.tag.EmployeeGroup.Role='Admin'": Adds a condition to restrict this admin-level access to only groups tagged with the role 'Admin'.
This policy ensures that only users in the groups tagged as Admin will be allowed to manage resources in the Test compartment, making it the most suitable choice for providing admin access.

NEW QUESTION # 25
How can OCI IAM be configured to facilitate cross-region access?
- A. The identity domain automatically replicates to the other region.
- B. Users can access resources in all regions by default.
- C. The administrator can grant users permissions to access specific resources in the other region.
- D. Identity domain replication must be enabled.
Answer: C
Explanation:
In Oracle Cloud Infrastructure (OCI), cross-region access is facilitated by configuring IAM policies that grant users or groups permissions to access resources in other regions. IAM policies in OCI are global, meaning they apply across all regions by default. However, an administrator can specifically configure these policies to allow or restrict access to resources in different regions.
Example: An administrator can write a policy that allows a user to manage compute instances in a specific region by including the region's name in the policy statement.

Which TWO statements are true about performing a multipart upload using the Multipart Upload API?
- A. You can keep adding parts as long as the total number is less than 10,000.
- B. You do not have to commit the upload after uploading all parts.
- C. Each part can be as large as 50 GIB.
- D. You do not need to split the object into parts.
Answer: A,C
Explanation:
When performing a multipart upload using the Multipart Upload API in Oracle Cloud Infrastructure (OCI) Object Storage, the following points are true:
C . Each part can be as large as 50 GiB: OCI allows each part of a multipart upload to be up to 50 GiB in size. This enables the efficient uploading of large objects in smaller, manageable parts.
D . You can keep adding parts as long as the total number is less than 10,000: The Multipart Upload API supports up to 10,000 parts for a single object. This allows the upload of very large objects by dividing them into multiple parts.
Incorrect Statements:
A . After uploading all parts, you must commit the upload to finalize the multipart upload and combine all parts into a single object.
B . The object must be split into parts before uploading when using the Multipart Upload API.

NEW QUESTION # 27
What would happen if you choose not to proactively reboot the instance before the scheduled maintenance due date?
- A. You will receive another notification to reboot within the next 7 days.
- B. The instance will get terminated.
- C. The instance is either reboot-migrated or rebuilt in place for you.
- D. You will receive another notification to reboot within the next 14 days.
Answer: C
Explanation:
In OCI, if you choose not to proactively reboot your instance before the scheduled maintenance due date, the system will handle the maintenance automatically to ensure that the instance remains operational.
Reboot-Migration or Rebuild in Place: If you don't reboot the instance yourself, OCI will automatically perform a reboot-migration or rebuild in place for the instance. This ensures that the instance is moved to new hardware or updated without your intervention, maintaining uptime and applying necessary updates or fixes.
Impact on Instance: The exact action taken (reboot-migration or rebuild in place) depends on the type of maintenance required. However, either action will temporarily interrupt the instance, typically involving a reboot, but the instance's data and configuration will be preserved.

NEW QUESTION # 29
How will moving a database instance to a different compartment impact user access?
- A. IAM policies are not tied to compartments.
- B. Compartments are not covered by IAM policies.
- C. Compartments prevent resource movement.
- 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.

Moving Resources
These resources provide detailed steps on how compartment changes impact resource access and management.
NEW QUESTION # 30
You enabled Cross Region Replication for the volume and selected US West (San Jose) as the destination region. What should you do to create a new volume from the volume replica?
- A. No action required. By default, the replica is available as a block volume.
- B. Activate the replica.
- C. Initiate the replica.
- D. Trigger the replica.
Answer: A
Explanation:
When Cross-Region Replication is enabled for a block volume in Oracle Cloud Infrastructure (OCI), the replication process automatically creates and maintains a synchronized copy of the block volume in the selected destination region (in this case, US West (San Jose)).
Replica Availability: The replicated volume is immediately available as a block volume in the destination region. You do not need to take any additional action to activate or trigger the replica.
Creating New Volumes: Since the replica is automatically available as a block volume, you can directly use it to create a new volume in the destination region without any manual intervention.
Relevant OCI Documentation:
Cross-Region Block Volume Replication
This documentation outlines how cross-region replication works and confirms that no additional steps are needed to create a new volume from a replica

NEW QUESTION # 34
Which compute capacity type would you select to meet these requirements?
- A. Preemptible capacity
- B. Capacity reservation
- C. On-demand capacity
- D. Dedicated host
Answer: C
Explanation:
On-demand capacity is the compute capacity type in Oracle Cloud Infrastructure (OCI) that allows you to provision and use compute instances whenever needed, without any long-term commitment. This flexibility is ideal for various workloads, including development, testing, and production environments, where immediate availability and scalability are crucial.
Key Points:
On-Demand Capacity: On-demand compute instances provide users with the flexibility to spin up instances as required and only pay for the time the instances are running. This model is most suitable for workloads with unpredictable usage patterns or short-term requirements.
Flexibility and Scalability: With on-demand capacity, you can quickly scale your resources up or down based on your application's needs, ensuring that you only pay for the resources you actually use.
No Commitment: Unlike reserved capacity, on-demand capacity does not require any long-term commitment or upfront payment, making it an attractive option for organizations looking to avoid capital expenditures.
Reference:
Oracle Cloud Infrastructure Documentation: OCI Compute Pricing
Oracle Cloud Infrastructure Documentation: Compute Instance Lifecycle
Explanation of Incorrect Options:
A . Capacity reservation: This option allows you to reserve capacity in advance, ensuring that resources are available when needed. It's ideal for predictable workloads but may not be as cost-effective for fluctuating demands.
B . Preemptible capacity: Preemptible instances are a lower-cost option where instances can be terminated by OCI if resources are needed elsewhere. This is suitable for non-critical workloads that can tolerate interruptions.
D . Dedicated host: Dedicated hosts provide physical servers for your exclusive use, offering isolation and predictable performance. This option is more suitable for workloads requiring dedicated resources or compliance needs.
Thus, Option C: On-demand capacity is the correct choice for most general-purpose workloads needing flexibility and immediate availability without long-term commitment.
NEW QUESTION # 35
Which TWO statements are TRUE about Private IP addresses in Oracle Cloud Infrastructure (OCI)?
- A. A private IP can have an optional public IP assigned to it if it resides in a public subnet.
- B. Each VNIC can only have one private IP address.
- C. By default, the primary VNIC of an instance in a subnet has one primary private IP address.
- D. By default, the primary VNIC of an instance in a subnet has one primary private IP address and one secondary private IP address.
Answer: A,C
Explanation:
In Oracle Cloud Infrastructure (OCI), understanding how private IP addresses work is crucial for configuring network interfaces and managing instances within your Virtual Cloud Network (VCN).
Primary VNIC and Private IP Address:
When an instance is launched in OCI, it is attached to a Virtual Network Interface Card (VNIC). The primary VNIC, which is automatically created during the instance launch, is associated with a primary private IP address by default. This private IP address is essential for the instance to communicate within the VCN. The primary private IP address is automatically assigned and cannot be removed from the primary VNIC while the instance is running. This supports the statement C.
Additional Private IPs:
Contrary to statement B, each VNIC can indeed have multiple private IP addresses, but by default, the primary VNIC comes with only one primary private IP. You can manually add secondary private IPs if needed. However, the additional IPs are not assigned by default; hence, A is incorrect.
Public IP Association:
For instances requiring internet access, a public IP address can be optionally assigned to the private IP address if the instance is in a public subnet. This is critical for scenarios where an instance needs to communicate with the internet or external networks. This aligns with statement D.
Relevant OCI Documentation:
Oracle Cloud Infrastructure Networking Overview
VNICs and Private IPs
These references provide additional context and detail on how private IP addresses work within OCI and clarify the correct statements.
NEW QUESTION # 36
Which statement is true about pre-authenticated requests?
- A. Pre-authenticated requests can be used to delete buckets.
- B. You need to provide your OCI credentials to the partner company.
- C. Deleting a pre-authenticated request does not revoke access.
- D. You cannot edit a pre-authenticated request.
Answer: D
Explanation:
In Oracle Cloud Infrastructure (OCI), pre-authenticated requests (PARs) allow users to grant access to specific objects in Object Storage without requiring the recipient to have an OCI account or credentials. This feature is useful for sharing objects securely without exposing broader access.
Cannot Edit a PAR: Once a pre-authenticated request is created, you cannot edit it. If you need to change the settings, such as the expiration date or the object being shared, you must delete the existing PAR and create a new one.
Other Statements:
Deleting a PAR does indeed revoke access immediately, contradicting option B.
Providing OCI credentials (C) is not required for using PARs. The purpose of PARs is to avoid sharing credentials.
Deleting Buckets (D): PARs are designed for accessing objects, not for administrative actions like deleting buckets.
Relevant OCI Documentation:
Managing Pre-Authenticated Requests
This reference outlines the features and limitations of pre-authenticated requests, including the inability to edit them once created.
NEW QUESTION # 37
Which image option allows you to create identical instances with minimal effort?
- A. Create a custom image
- B. Bring your own image
- C. Select an image from the OCI Marketplace
- D. Use Oracle-provided images
Answer: A
Explanation:
When you need to create identical instances with minimal effort, creating a custom image is the best option.
Custom Images: A custom image captures the exact configuration of an instance, including the OS, software, configurations, and data. By using a custom image, you can easily replicate the same setup across multiple instances, ensuring consistency and reducing the need for manual configuration each time.
Other Options:
Bring Your Own Image: This allows you to import your custom OS image into OCI, but it's more suited for cases where you are migrating from another environment.
Select an Image from the OCI Marketplace: This provides pre-configured images from Oracle or third parties, but they may require additional setup to match your specific requirements.
Use Oracle-Provided Images: These are basic images provided by Oracle, which may not include the specific customizations you need.

Which Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) policy is invalid?
- A. Allow dynamic-group 'Default'/'FrontEnd' to manage instance-family in compartment Project-A
- B. Allow group 'Default'/'A-Admins' to manage all-resources in compartment Project-A
- C. Allow any-user to inspect users in tenancy
- D. Allow group 'Default'/'A-Developers' to create volumes in compartment Project-A
Answer: C
Explanation:
In Oracle Cloud Infrastructure (OCI), Identity and Access Management (IAM) policies are used to control access to resources. The policy in option C is invalid because "any-user" is not a valid principal in OCI IAM policies. OCI policies can only grant permissions to groups or dynamic groups, but not to arbitrary users.
Here's an explanation for each option:
A . Allow dynamic-group 'Default'/'FrontEnd' to manage instance-family in compartment Project-A: This is valid. It grants the dynamic group 'FrontEnd' the ability to manage instances within the Project-A compartment.
B . Allow group 'Default'/'A-Admins' to manage all-resources in compartment Project-A: This is valid. It provides full administrative access to all resources in the Project-A compartment for the 'A-Admins' group.
C . Allow any-user to inspect users in tenancy: This is invalid because OCI does not allow the use of "any-user" in policies. You must specify a valid group or dynamic group to define permissions.
D . Allow group 'Default'/'A-Developers' to create volumes in compartment Project-A: This is valid. It permits the 'A-Developers' group to create volumes in the Project-A compartment.
