An insurance company is storing critical financial data in the OCI block volume. This volume is currently encrypted using oracle managed keys. Due to regulatory compliance, the customer wants to encrypt the data using the keys that they can control and not the keys which are controlled by Oracle.
What of the following series of tasks are required to encrypt the block volume using customer managed keys?

• A. Create a vault, import your master encryption key into the vault, generate data encryption key, assign data encryption key to the block volume
• B. Create a master encryption key, create a data encryption key, decrypt the block volume using existing oracle managed keys, encrypt the block volume using the data encryption key
• C. Create a vault, create a master encryption key in the vault, assign this master encryption key to the block volume D. Create a master encryption key, create a new version of the encryption key, decrypt the block volume using existing oracle managed keys and encrypt using new version of the encryption key

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 set up a Service Gateway to send metrics to the OCI Monitoring service.
• B. You need to assign a reserved public IP address to the compute instances.
• C. Autoscaling only works with single availability domains.
• D. Autoscaling only works for instances with public IP addresses.

A data analytics company has been building Its now generation big data and analytics platform on Oracle Cloud Infrastructure (OCI). They need a storage service that provide the scale and performance that their big data applications require such as high throughput to compute nodes with low latency file operations in addition, their data needs to be stored redundantly across multiple nodes In a single availability domain and allows concurrent connections from multiple compute Instances hosted on multiple availability domains.
Which OCI storage service can you use to meet i his requirement?

• A. Archive storage
• B. Object Storage
• C. Block Volume
• D. File System Storage

You have been asked to implement a bespoke financial application in Oracle Cloud Infrastructure using virtual machine instances controlled by Autoscaling across multiple Availability Domains. The application stores transaction logs, intermediate transaction data, and audit data and needs to store this on a persistent, durable data store accessible from all of the application servers. The application requires the file system to be mounted in the /audit folder on the Linux file system. The system needs to tolerate the failure of two or more Fault Domains and still maintain data integrity. The solution should be as low maintenance as possible.
What storage architecture should you suggest?

• A. Use File Storage Service(FSS). Configure FSS to operate from all Availability Domains the application servers operate in and mount the file system in the /audit folder.
• B. Store the data on Oracle Object Storage mounted at the /audit mount point on all the Linux instances using the default mount options.
• C. Implement a single instance and install an NFS server, configure and create an NFS share, and mount this as /audit on the application instances.
• D. Use locally attached NVMe instances and configure RAID 0 replication between servers.

Which three scenarios are suitable for the use of Oracle Cloud Infrastructure (OCI) Autonomous Transaction Processing - Serverless (ATP-S) deployment? (Choose three.)

• A. A developer working on an internal project needs to use a database during work hours but doesn't need it during nights or weekends. The project budget requires her to keep costs low.
• B. A midsize company is considering migrating its legacy on-premises MongoDB database to Oracle Cloud Infrastructure (OCI). The database has significantly higher workloads on weekends than weekdays.
• C. A manufacturing company is running Oracle E-Business Suite application on-premises. They are looking to move this application to OCI and they want to use a managed database offering for their database tier.
• D. A small startup is deploying a new application for eCommerce and it requires a database to store customers' transactions. The team is unsure of what the load will look like since it is a new application.
• E. A well-established, online auction marketplace is running an application where there is database usage 24x7, but also has peaks of activity that are hard to predict. When the peaks happen, the total activities may reach 3 times the normal activity level.
