A large London based eCommerce company is running Oracle DB System Virtual RAC database on Oracle Cloud Infrastructure (OCI) for their eCommerce application activity. They are launching a new product soon, which is expected to sell in large quantities all over the world. The application architecture should have minimal cost, no data loss, no performance impacts during the database backup windows and should have minimal downtime.

A. Launch a new VM RAC database in another availability domain, launch a compute instance, deploy Oracle GoldenGate on it and then configure it to replicate the data from the eCommerce Database over to the new RAC database using GoldenGate. Take backups from the new VM RAC database.

B. Turn off automated backups from the eCommerce database, implement Oracle Data Guard with the Standby database deployed on another availability domain, take backups from the standby database.

C. Launch a new VM RAC database in another availability domain, launch a compute instance, deploy Oracle GoldenGate on it and then configure bi-directional replication from the eCommerce Database over to the new VM RAC database using GoldenGate. Take backups from the new VM RAC database.

D. Turn off automatic backups from the eCommerce database, implement Oracle Active Data Guard with the standby database deployed on another availability domain, and take backups from the standby database.

Give this compartment structure:

You want to move a compute instance that is in 'Compute' compartment to 'SysTes-Team'. You login to your Oracle Cloud Infrastructure (OCI)account and use the 'Move Resource' option. What will happen when you attempt moving the compute resource?

A. The move will be successful though Compute Instance and its Public and Private IP address will stay the same. The Compute instance VNIC will need to be moved separately. The Compute instance will still be associated with the original VCN.

B. The move will fail and you will be prompted to move the VCN first. Once VCN is moved to the target compartment, the Compute instance can be moved.

C. The move will be successful though Compute Instance Public and Private IP address changed, and it will be associated to the VCN in target compartment.

D. The move will be successful though Compute Instance and its Public and Private IP address will stay the same. The Compute instance VNIC will still be associated with the original VCN.

A cloud consultant is working on implementation project on OCI. As part of the compliance requirements,

the objects placed in object storage should be automatically archived first and then deleted. He is testing a

Lifecycle Policy on Object Storage and created a policy as below:

[ { "name": "Archive_doc", "action": "ARCHIVE", "objectNameFilter": { "inclusionPrefixes": "doc"] },

"timeAmount": 5, "timeunit": "DAYS", "isEnabled": true }, { "name": "Delete_doc", "action": "DELETE",

"objectNameFilter": "inclusionPrefixes": [ "doc"] 1."timeAmount": 5, "timeunit": "DAYS", "isEnabled": true }

What will happen after this policy is applied?

A. All objects with names starting with "doc" will be deleted after 5 days of object creation

B. All the objects having file extension ".doc" will be archived for 5 days and will be deleted 10 days after object creation

C. All the objects having file extension ".doc" will be archived 5 days after object creation

D. All the objects with names starting with "doc" will be archived 5 days after object creation and will be deleted 5 days after archival

You are part of a project team working in the development environment created in OCI. You have realized that the CIDR block specified for one of the subnet in a VCN is not correct and want to delete the subnet. While deleting you are getting 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 "GetVnic" operation to find out the parent resource of the VNIC

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

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

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

Which of the below options is true regarding Oracle Cloud Infrastructure's load balancing service?

A. You can dynamically change the load balancer shape to handle more incoming traffic.

B. The public load balancer applies a floating public IP address to the primary load balancer.

C. When you create a private load balancer, the service requires 2 or more subnets to host both the primary and standby load balancers.

D. A public load balancer is Availability Domain specific in scope.

A global media organization is working on a project which lets users upload their videos to the site. After upload is complete, the video should be automatically processed by an Al algorithm. The algorithm will try to recognize certain actions in the videos so that it can be used to show related advertisements in future. The development team wants to focus on writing Al code and not worry about underlying infrastructure for high availability, scalability, security and monitoring. Which Oracle Cloud Infrastructure (OCI) services would meet these requirements?

A. OCI Object Storage, OCI Events service and OCI Functions.

B. Oracle Container Engine for Kubernetes, OCI Notifications and OCI Object Storage.

C. OCI Events, Oracle Container Engine for Kubernetes and OCI Digital Assistant.

D. OCI Resource Manager, OCI Functions and OCI Events service.

You are working as a solution architect for a customer in Frankfurt, which uses multiple compute instance VMs spread among three Availability Domains in the Oracle Cloud Infrastructure (OCI) eu- frankfurt-1 region. The compute instances do not have public IP addresses and are running in private subnets inside a Virtual Cloud Network (VCN). You have set up OCI Autoscaling feature for the compute instances, but find out that instances cannot be auto scaled. You have enabled monitoring on the instances. What could be wrong in this situation?

A. You need to assign a reserved public IP address to the compute instances.

B. You need to set up a Service Gateway to send metrics to the OCI Monitoring service.

C. Autoscaling only works for instances with public IP addresses.

D. Autoscaling only works with single availability domains.

Your company needs to migrate a business critical application from your data center to Oracle Cloud Infrastructure (OCI). The application runs on Oracle Database and both the application and database servers run on Oracle Linux version 7. The application server is WebLogic server running on multiple 4-core servers and the database is deployed as an Oracle Database Enterprise Edition RAC database on 2 servers (4-cores each). Which method of database migration should you choose so that the application has minimal impact? (Choose the best answer.)

A. Deploy Virtual Machine RAC DB system on OCI and use the Oracle Database Backup module with RMAN to migrate the data from customer on-premises to OCI.

B. Deploy Virtual Machine RAC DB system on OCI and use the ZDM tool for the database migration.

C. Deploy Autonomous Transaction Processing Database on OCI and use the MV2ADB tool for the database migration.

D. Deploy Exadata Cloud Service Base rack and use Oracle Data Pump tool to migrate the data from customer on-premises to OCI.
