Oracle Exam 1Z0-997-20 Topic 6 Question 32 Discussion

Actual exam question for Oracle's 1Z0-997-20 exam

Question #: 32
Topic #: 6

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)?

AUpload all files to an Oracle Streaming Service (OSS) stream. Setup 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.

BUpload 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.

CBuild 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.

DUpload 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.
