Which three options are available to migrate an Oracle database 12.x from an on-premises environment to Oracle Cloud Infrastructure (OCI)?

A. Leverage OCI Storage Gateway asynchronous database migration option.

B. Use Oracle Data Pump Export/Import to migrate the database.

C. Configure RMAN cross-platform transportable tablespace backup sets.

D. Setup OCI schema and data transfer tool with Bare Metal DB Systems as the target.

E. Create a backup of your on-premises database In OCI DB Systems.

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 Oracle Cloud Infrastructure (OCI) Public Load Balancer's SSL certificate is expiring soon. You noticed the Load Balancer is configured with SSL Termination only. When the certificate expires, data traffic can be interrupted and security compromised.

What steps do you need to take to prevent this situation?

A. Add the new SSL certificate to the Load Balancer, update backend servers to work with a new certificate and edit listeners so they can use the new certificate bundle.

B. Add the new SSL certificate to the Load Balancer, update listeners and backend sets so they can use the new certificate bundle.

C. Add the new SSL certificate to the Load Balancer and implement end to end SSL so it can encrypt the traffic from clients all the way to the backend servers.

D. Add the new SSL certificate to the Load Balancer and update backend servers to use the new certificate bundle.

E. Add the new SSL certificate to the Load Balancer and update listeners to use the new certificate bundle.

You are working as a cloud consultant for a major media company. In the US and your client requested to consolidate all of their log streams, access logs, application logs, and security logs into a single system.

The client wants to analyze all of their logs In real-time based on heuristics and the result should be validated as well. This validation process requires going back to data samples extracted from the last 8 hours.

What approach should you take for this scenario?

A. Create an auto scaling pool of syslog-enabled servers using compute instances which will store the logs In Object storage, then use map reduce jobs to extract logs from Object storage, and apply heuristics on the logs.

B. Create a bare-metal instance big enough to host a syslog enabled server to process the logs and store logs on the locally attached NVMe SSDs for rapid retrieval of logs when needed.

C. Set up an OCI Audit service and ingest all the API arils from Audit service pragmatically to a client side application to apply heuristics and save the result in an OCI Object storage.

D. Stream all the logs and cloud events of Events service to Oracle Streaming Service. Build a client process that will apply heuristics on the logs and store them in an Object Storage.

You are a solution architect working with a startup that has decided to move their workload to Oracle Cloud Infrastructure. Since their workload is small, upon architecting, you decide its sufficient to use 8 compute instances to run their workload. The company wants to use a common storage for their instances. So, you propose the idea of attaching a block volume to multiple instances to provide a common storage.

Which of the below option is NOT true for such a solution?

A. If the block volume is already attached to an instance as read/write non-shareable you can't attach it to another instance until you detach it from the first instance.

B. Block volumes attached as read-only are configured as shareable by default.

C. You can delete a block volume from one instance without detaching it from all other instances there by keeping other instance's storage intact.

D. Once you attach a block volume to an instance as read-only, it can only be attached to other instances as read-only.
