Option A is incorrect because using OCI Traffic management service with failover steering policy will not distribute the traffic between OCI and on premises infrastructure.Failover steering policy will only route traffic to a secondary endpoint if the primary endpoint is unresponsive2. This is not suitable for a gradual migration scenario.

Option B is correct because using OCI Traffic management service with Load Balancing steering policy will distribute the traffic between OCI and on premises infrastructure based on a ratio or round robin algorithm2. This will allow you to control the percentage of traffic that goes to the new infrastructure in OCI and monitor the results.

Option C is incorrect because using an OCI load Balancer will not distribute the traffic between OCI and on premises infrastructure.A load balancer will only distribute the traffic among multiple compute instances within a single region in OCI2. This will not help you migrate from your on premises infrastructure.

Option D is incorrect because using VPN connectivity between on premises Infrastructure and OCI and creating routing tables to distribute the traffic between them will require more effort than using OCI Traffic management service.You will need to set up a VPN connection, configure routing rules, and monitor the network performance2. This will not be as simple and reliable as using a DNS-based solution.

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 .

Here are the steps to complete the challenge:

To create a new VCN with the name exam-vcn within your assigned compartment by using the Start VCN Wizard, follow these steps:

In the OCI Console, go to Networking and click Virtual Cloud Networks.

Select your assigned compartment from the list on the left.

Click Start VCN Wizard.

Select Create VCN with Internet Connectivity and click Start VCN Wizard.

Enter exam-vcn as the VCN Name and leave the other fields as default. Click Next.

Review the summary and click Create. This will create a VCN with a public subnet, a private subnet, an internet gateway, a NAT gateway, a service gateway, and a route table.

To create a new Oracle Functions application named exam-app within your assigned compartment by using the private subnet in your previously created VCN, follow these steps:

In the OCI Console, go to Developer Services and click Functions.

Select your assigned compartment from the list on the left.

Click Create Application.

Enter exam-app as the Application Name and select your previously created VCN from the VCN dropdown menu.

Select the private subnet from the Subnet dropdown menu and leave the other fields as default. Click Create. This will create an Oracle Functions application that can run serverless functions in a private subnet.

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 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.
