NEW QUESTION 22
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 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.
- B. 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.
- 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.
Answer: B
Explanation:
You can configure the Autonomous Database instance as a target database for Oracle GoldenGate. But You can't set up Oracle Autonomous Database as a source database for Oracle GoldenGate.
Recovery Point objective (RPO) of 24 hours and Recovery Time Objective (RTO) of 1 hour
- To provision new VM and restore the production database from the backup on object storage, will exceed the RTO 1 hour
- You can create the standby DB system in a different availability domain from the primary DB system for availability and disaster recovery purposes. With Data Guard and switchover/failover can meet RTO
1 hour.
- RAC Database is not required in this solution. Standalone will be most suitable and cost effective

NEW QUESTION 24
A global retailer has decided to re-design its e-commerce platform to have a micro-services architecture. They would like to decouple application architecture into smaller, independent services using Oracle Cloud Infrastructure (OCI). They have decided to use both containers and servers technologies to run these application instances.
Which option should you recommend to build this new platform?
- A. Use OCI functions, OCI object storage and OCI event service.
- B. Use Oracle Container Engine for kubernetes, OCI Registry and OCI Functions.
- C. Use OCI Resource Manager to automate compute Instances provisioning and use OCI Streaming service.
- D. Install a kubernetes cluster on OCI and use OCI event service.
Answer: B
Explanation:
Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs.
Oracle Cloud Infrastructure Container Engine for Kubernetes is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud. Use Container Engine for Kubernetes (sometimes abbreviated to just OKE) when your development team wants to reliably build, deploy, and manage cloud-native applications. You specify the compute resources that your applications require, and Container Engine for Kubernetes provisions them on Oracle Cloud Infrastructure in an existing OCI tenancy.

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 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 need to be moved separately. The Compute instance will still be associated with the original VCN.
Answer: A
Explanation:
Moving Resources to a Different Compartment
Most resources can be moved after they are created. There are a few resources that you can't move from one compartment to another. Some resources have attached resource dependencies and some don't.
Not all attached dependencies behave the same way when the parent resource moves.
For some resources, the attached dependencies move with the parent resource to the new compartment.
The parent resource moves immediately, but in some cases attached dependencies move asynchronously and are not visible in the new compartment until the move is complete.
For other resources, the attached resource dependencies do not move to the new compartment. You can move these attached resources independently.
You can move Compute resources such as instances, instance pools, and custom images from one compartment to another. When you move a Compute resource to a new compartment, associated resources such as boot volumes and VNICs are not moved.
You can move a VCN from one compartment to another. When you move a VCN, its associated VNICs, private IPs, and ephemeral IPs move with it to the new compartment.

NEW QUESTION 34
An OCI Architect is working on a solution consisting of analysis of data from clinical trials of a pharmaceutical company. The data is being stored in OCI Autonomous Data Warehouse (ADW) having 8 CPU Cores and 70 TB of storage. The architect is planning to setup autoscaling to respond to dynamic changes in the workload.
Which of the following needs to be considered while configuring auto scaling? Choose two
- A. Enabling auto scaling does not change the concurrency and parallelism settings
- B. The maximum CPU cores that will be automatically allocated for this database is 16 CPUs
- C. Auto scaling also scales IO throughput linearly along with CPU
- D. The database memory SGA and PGA will not get affected by the changes in the number of CPUs during auto scaling
Answer: A,C
Explanation:
Explanation
Auto scaling is enabled by default when you create an Autonomous Database instance or you can use Scale Up/Down on the Oracle Cloud Infrastructure console to enable or disable auto scaling.
With auto scaling enabled the database can use up to three times more CPU and IO resources than specified by the number of OCPUs currently shown in the Scale Up/Down dialog. When auto scaling is enabled, if your workload requires additional CPU and IO resources the database automatically uses the resources without any manual intervention required.
Enabling auto scaling does not change the concurrency and parallelism settings for the predefined services IO throughput depends on the number of CPUs you provision and scales linearly with the number of CPUs.
