Option A is correct because using multiple OCI Data Transfer Appliances to transfer data to OCI is the most effective service to use to migrate the data to OCI given the time constraints. This option can securely move terabytes or petabytes of data between on-premises data centers and the cloud in days instead of weeks or months. It also avoids using the public internet, which can be slow, unreliable, and expensive45.
Option B is incorrect because setting up an OCI Storage Gateway to connect your data center and your VCN and uploading all data to OCI is not effective given the time constraints. This option requires using the public internet, which can be intermittent due to the damages caused by the hurricane. It also requires installing and configuring a software appliance on your premises, which can add complexity and overhead6.
Option C is incorrect because setting up a hybrid network by launching a 1Gbps FastConnect virtual circuit between your data center and OCI and using OCI Object Storage multipart upload tool to automate the migration of your data to OCI is not feasible given the time constraints. This option requires provisioning a FastConnect circuit, which can take several days or weeks depending on your network provider. It also requires using a public internet backup path, which can be unreliable due to the hurricane .
Option D is incorrect because setting up an OCI Storage Gateway to connect your data center and your VCN and uploading all data to OCI using OCI Storage Gateway Cloud Sync tool is not effective given the time constraints. This option requires using the public internet, which can be intermittent due to the damages caused by the hurricane. It also requires installing and configuring a software appliance on your premises, which can add complexity and overhead6.
Option E is incorrect because uploading the data to OCI using OCI Object Storage multipart upload tool is not effective given the time constraints. This option requires using the public internet, which can be slow, unreliable, and expensive due to the hurricane and the large amount of data involved

Option A is correct because using Autonomous Transaction Processing with shared Exadata infrastructure is the most suitable option for running seasonal workloads in Oracle Cloud Infrastructure.
Autonomous Transaction Processing is a fully managed, serverless, and elastic database service that can scale up or down automatically based on the workload demand. It also supports stopping and starting the database to save costs when it is not in use.It runs on Exadata infrastructure, which provides high performance, availability, and security for transactional and mixed workloads12.
Option B is incorrect because using Oracle Cloud Infrastructure Exadata DB Systems is not optimal for running seasonal workloads in Oracle Cloud Infrastructure. Exadata DB Systems are dedicated, high-performance database systems that can run multiple databases with different shapes and versions.
However, they are not serverless or elastic, and they do not support stopping and starting the database.They are more suitable for mission-critical and steady-state workloads that require consistent performance and availability3.
Option C is incorrect because using Oracle Cloud Infrastructure Virtual Machine DB Systems is not optimal for running seasonal workloads in Oracle Cloud Infrastructure. Virtual Machine DB Systems are flexible and cost-effective database systems that can run single-node or RAC databases with different shapes and versions. However, they are not serverless or elastic, and they do not support stopping and starting the database. They are more suitable for development, testing, or production workloads that require moderate performance and availability .
Option D is incorrect because using Oracle Cloud Infrastructure Bare Metal DB Systems is not optimal for running seasonal workloads in Oracle Cloud Infrastructure. Bare Metal DB Systems are high-performance database systems that run single-node databases with locally attached NVMe storage.
However, they are not serverless or elastic, and they do not support stopping and starting the database.
They are more suitable for high-performance, latency-sensitive, specialized, or traditional workloads that require full control over the entire cloud stack .

Option A is incorrect because rclone is not a tool provided by Object Storage. It is a third-party command-line program that can sync files to and from various cloud storage providers, including Object Storage1.
Option B is incorrect because contiguous numbers are not required for each part. Object Storage constructs the object by ordering part numbers in ascending order only if they are not specified in the commit operation1.
Option C is correct because after initiating a multipart upload, you need to explicitly commit or abort it. Otherwise, it remains active until it expires after 24 hours1.
Option D is incorrect because Object Storage does not provide APIs to split a file into multiple parts. You need to use your own tools or programs to do that1.
Option E is correct because you can list all parts that have been uploaded for an active multipart upload by using the ListMultipartUploadParts API or CLI command. However, you cannot list information for an individual object part by using the GetObject API or CLI command1.

See the explanation for this task.
Explanation
One possible IAM policy statement that allows API Gateway to access Oracle Functions in your compartment is:
ALLOW any-user to use functions-family in compartment <your-compartment-name> where ALL
{request.principal.type = 'ApiGateway', request.resource.compartment.id = '<your-compartment-OCID>'} This statement grants the any-user group the permission to use the functions-family resource type in the specified compartment, but only if the request is coming from an API Gateway and the function belongs to the same compartment as the API Gateway. For more information, seeCreate a Policy to Give API Gateways Access to Functions.

Option A is incorrect because restarting the dcsagent program might be necessary if it has the status of stop/waiting to resolve a backup failure1. This isone of the possible database service agent issues that can cause backup failures.
Option B is incorrect because setting the database archiving mode to NOARCHIVELOG will prevent you from performing online backups. You need to set the database archiving mode to ARCHIVELOG to enable online backups1. This is one of the possible database issues that can cause backup failures.
Option C is correct because ensuring that your database host can connect to OCI Object Storage is essential for performing backups. You need to check the object store connectivity issues that can cause backup failures, such as firewall rules, proxy settings, network routes, and security lists1.
