C. It is possible to split this file into multiple parts using rclone tool provided by Object Storage.

D. After initiating a multipart upload by making a CreateMultlPartUpload RESI API Call, the upload remains active until you explicitly commit it or abort.

E. Contiguous numbers need to be assigned for each part so that Object Storage constructs the object by ordering, part numbers in ascending order

All three Data Guard Configuration are fully supported on Oracle Cloud infrastructure (OCI). You want to deploy a maximum availability architecture (MAA) for database workload. Which option should you consider while designing your Data Guard configuration to ensure best RTO and PRO without causing any data loss?

A. Configure "Maximum Protection" mode which provides zero data loss If the primary database fails.

B. Configure "Maximum Performance" mode In SYNC mode between two availability domains (same region) which provides, the highest level of data protection that is possible without affecting the performance of the primary database.

C. Configure ''Maximum Scalability" mode which provides the highest level of scalability without compromising the availability of the primary database.

D. Configure ''Maximum Availability" mode in SYNC mode between two availability domains (same region), and use the Maximum Availability mode in SYNC mode between two regions.

An automobile company wants to deploy their CRM application for Oracle Database on Oracle Cloud Infrastructure (OC1) DB Systems for one of major clients. In compliance with the Business Continuity Program of the client, they need to provide a Recovery Point objective (RPO) of 24 hours and a Recovery time objective (RTO) of 24 hours and Recovery Time Objective (RTO) of 1 hour. The CRM application should be available oven in me event that an entire on Region is down. Which approach Is the most suitable and cost effective configuration for this scenario?

A. Deploy a 1 node VM Oracle database in one region and replicate the database to a 1 node VM Oracle database in another region using a manual setup and configuration of Oracle Data Guard.

B. Deploy a 2 node Virtual Machine (VM) Oracle RAC database in one region and replicate the database to a 2 node VM Oracle RAC database in another region using a manual setup and configuration of Oracle Data Guard.

C. Deploy a 1 node VM Oracle database in one region. Manual Configure a Recovery Manager (RMAN) database backup schedule to take hourly database backups. Asynchronously copy the database backups to object storage in another OCI region, If the primary OCI region is unavailable launch a new 1 new VM Database in the other OCI region restore the production database from the backup.

D. Deploy an Autonomous Transaction Processing (Serverless) database in one region and replicate it to an Autonomous Transaction Processing (Serverless) database in another region Oracle GoldenGate.

An upcoming e-commerce company has deployed their online shopping application on OCI. The application was deployed on compute instances with autoscaling configuration for application servers fronted by a load balancer and OCI Autonomous Transaction Processing (ATP) in the backend. In order to promote their e-commerce platform 50% discount was announced on all the products for a limited period. During the day 1 of promotional period it was observed that the application is running slow and company's hotline is flooded with complaints. What could be two possible reasons for this situation?

A. The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation

B. As part of autoscaling, the load balancer shape has dynamically changed to a larger shape to handle more incoming traffic and the system was slow for a short time during this change

C. The health check on some of the backend servers has failed and the load balancer was rebooting these servers.

D. The autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room of scaling

You are tasked with migrating an online shopping website to Oracle Cloud Infrastructure (OCI) and decide to use a Load Balancer. You have configured the backend set with the round robin policy. During the testing phase, you noticed that users are losing items from their shopping carts when they navigate to different pages. How should you implement a solution to this problem?

A. Set up a Traffic Management Steering Policy to redirect traffic to a different backend set that is deployed exclusively for the purpose of holding all Items placed in the shopping cart.

B. Configure a set of path route rules that will route to different backend sets based on the URI requested by the customer's browser.

C. Replace the round robin policy with least connections policy at the backend set.

D. Set up session persistence at the Load Balancer backend set.

Which of the following is NOT a good use case for using the functionality available in the Oracle Cloud Infrastructure (OCI) Events service?

A. Publish all events in a specific compartment to Oracle Streaming service for later analysis.

B. Triggers Function using Oracle Functions when new files are uploaded in an OCI Object Storage bucket.

C. Publish a notification when long lived tasks complete, such as OCI Autonomous Database backup completion.

D. Capture Monitoring Alarms and invoke Autoscaling of compute instances.

E. Trigger a notification when a function completes its execution.

You are part of a project team working in the development environment created in Oracle Cloud Infrastructure (OCI). You realize that the CIDR block specified for one of the subnets in a Virtual Cloud Network (VCN) is not correct and want to delete the subnet. While deleting you get an error indicating that there are still resources that you must delete first. The error includes the OCID of the VNIC that is in the subnet. Which of the following action you will take to troubleshoot this issue?

A. Use OCI CLI to call "network vnic" and "compute vnic-attachment" operations to find out the parent resource of the VNIC.

B. Use OCI CLI to delete the VNIC first and then delete the subnet.

C. Use OCI CLI to delete the subnet using -force option.

D. Copy and paste OCID of the VNIC in the search box of the OCI Console to find out the parent resource of the VNIC.

As part of planning the network design on Oracle Cloud Infrastructure, you have been asked to create an Oracle Cloud Infrastructure Virtual Cloud Network (VCN) with 3 subnets, one in each Availability Domain. Each subnet needs to have a minimum of 64 usable IP addresses. What is the smallest subnet and VCN size you should use to implement this design? The requirements are static, so no growth is expected.

A. 122 for the VCN; 124 for the subnets

B. /23 for the VCN; /25 for the subnets

C. /24 for the VCN; /24 for the subnets

D. /22 for the VCN; /25 for the subnets

A company is running High Performance Computing workloads on Oracle Cloud Infrastructure and are

using OCI bare metal compute shape. They have decided to create a custom image of the bare metal

instance's boot disk and use it to launch other instances.

Which of the following is a NOT a true statement?

A. Before you create a custom image of an instance, you must disconnect all iSCSI attachments and remove all iscsid node configurations from the instance.

B. Editing custom Windows images is not supported due to hardware differences between shapes.

C. Custom images do not include the data from any attached block volumes.

D. You can create additional custom images of an instance while the instance is engaged in the image creation process.
