You work for a retail company and they developed a Microservices based shopping application that needs to access Oracle Autonomous Database from the application. As an Architect, you have been tasked to treat all of the application components as Kubernetes native objects, such as the microservices, Oracle Autonomous database, Kubernetes services, etc.
What should you do to make sure that you can use Kubernetes constructs to manage the life cycle of the application components, including Oracle Autonomous Database? (Choose the best answer.)

• A.Create an Oracle Cloud Infrastructure (OCI) Service Gateway and connect to the Oracle Autonomous Database using the private IP address from the microservice.
• B.Provision an Oracle Autonomous Database and then use OCI Service Broker to access the database as a native component to your Kubernetes cluster.
• C.Create a service from the Kubernetes cluster and point to the Oracle Autonomous Database using its FQDN.
• D.Install and secure the OCI Service Broker for Kubernetes. Then provision and bind to the required Oracle Cloud Infrastructure services.

You have been asked to review some network proposals by a major client. The client's IT director needs to provision two Virtual Cloud Network (VCN) for a major application. Both applications use a large number of virtual machine instances, and so will ideally occupy VCNs with as many address spaces as possible. Additionally, in the future, VCN peering will be required to allow communication between the VCNs.
Which of the following are valid IP ranges to consider for the VCNs?

• A.10.0.0.0/8 and 11.0.0.0/8
• B.10.0.0.0/24 and 10.0.1.0/24
• C.10.0.0.0/16 and 10.0.64.0/24
• D.10.0.1.0/24 and 10.0.1.0/27

Which of the following is NOT a good use case for the volume backup feature of the Oracle Cloud Infrastructure Block Volume service?

• A.Retain a copy of data in a volume, so that you can duplicate an environment later or preserve the data for future use.
• B.Meet compliance and regulatory requirements for data to remain unchanged over time, so that it can be retrieved for audit purposes.
• C.Rapidly duplicate an environment in seconds to test configuration changes without impacting your production environment.
• D.Support business continuity requirements of reducing the risk of outages or data mutation over time.

A customer has a Virtual Machine instance running in their Oracle Cloud Infrastructure tenancy. They realized that they wrongly picked a smaller shape for their compute instance. They are reaching out to you to help them fix the issue.
Which of the below options is best recommended to suggest to the customer?

• A.Delete the running instance and spin up a new instance with the desired shape.
• B.Change the shape of instance without reboot, but stop all the applications running on instance beforehand to prevent data corruption.
• C.Change the shape of the virtual machine instance using the Change Shape feature available in the console.
• D.OCI doesn't allow such an operation.

You want to automate the processing of new Image files to generate thumbnails. the expected rate is 10 new files every hour.
Which of the following is the most cost effective option to meet this requirement in Oracle Cloud Infrastructure (OCI)?

• A.Upload files to an OCI Object storage bucket. Every time a file is uploaded, an event is emitted. Write a rule to filter these events with an action to trigger a function in Oracle Functions. The function processes the image in the file and stores the thumbnails back in an Object storage bucket.
• B.Upload files to an OCI Object storage bucket. Every time a file is uploaded, trigger an event with an action to provision a compute instance with a cloud-init script to access the file, process it and store it back in an Object storage bucket. Terminate the instance using Autoscaling policy after the processing is finished.
• C.Build a web application to ingest the files and save them to a NoSQL Database. Configure OCI Events service to trigger a notification using Oracle Notification Service (ONS). ONS invokes a custom application to process the image files to generate thumbnails. Store thumbnails in a NoSQL Database table.
• D.Upload all files to an Oracle Streaming Service (OSS) stream. Set up a cron job to invoke a function in Oracle Functions to fetch data from the stream. Invoke another function to process the image files and generate thumbnails. Store thumbnails in another OSS stream.

Correct Answer: A

You can invoke a function that you've deployed to Oracle Functions by triggered by an event in the Events service when update the Object storage to fetch the data then the function can process the File and store back to Object storage
