Question # 6

You have been askedto 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.

10.0.0.0/24 and 10.0.1.0/24

B.

10.0.1.0/24 and10.0.1.0/27

Question # 14

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 thisrequirement 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.
