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.

The Network Visualizer tool in Oracle Cloud Infrastructure is valuable because itvisualizes the topology of all Virtual Cloud Networks (VCNs)in a selected region and tenancy.

Topology Visualization: The Network Visualizer provides a graphical representation of the network components and their relationships within a VCN, including subnets, route tables, gateways, and security lists. This visualization helps users understand the network architecture and troubleshoot issues effectively.

Other Options:

Real-time monitoring of network traffic (B),detailed information about physical network components (C), andautomated reports on network performance metrics (D)are not the primary functions of the Network Visualizer. These functionalities are typically handled by other OCI services or tools.

Relevant OCI Documentation:

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 statementC.

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,Ais 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 statementD.

To calculate the monthly cost for 7 Petabytes (PB) of outbound data transfer at a rate of $0.0085 per GB in North America:

Calculation:

1 PB = 1,000,000 GB

7 PB = 7,000,000 GB

Cost = 7,000,000 GB * $0.0085/GB = $59,500.00

Thus, the cost for 7 PB of outbound data transfer per month is$59,500.00.

Geolocation Steeringin OCI's Traffic Management Steering Policy allows you to distribute DNS traffic based on the geographical location of the end users. This method helps direct users to the nearest regional endpoint, optimizing latency and improving user experience.

Use Cases:Geolocation Steering is commonly used to deliver region-specific content, comply with data residency laws, or optimize service performance by directing traffic to the closest available servers.

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 PARdoes 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.

This reference outlines the features and limitations of pre-authenticated requests, including the inability to edit them once created.

=================

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

In Oracle Cloud Infrastructure (OCI), Identity and Access Management (IAM) policies are used to control access to resources. The policy in optionCis invalid because"any-user"is not a valid principal in OCI IAM policies. OCI policies can only grant permissions togroupsordynamic 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.

When ensuring that third-party APIs communicate securely with OCI resources, the appropriate authentication option isAPI 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.

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.

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.
