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)?

• 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.

• 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.

• 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.

• 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.

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

• Enabling auto scaling does not change the concurrency and parallelism settings

• Auto scaling also scales IO throughput linearly along with CPU

• The database memory SGA and PGA will not get affected by the changes in the number of CPUs during auto scaling

• The maximum CPU cores that will be automatically allocated for this database is 16 CPUs

A manufacturing company is planning to migrate their on-premises database to OCI and has hired you for the migration. Customer has provided following information regarding their existing onpremises database:

Database version, host operating system and version, database character set, storage for data staging, acceptable length of system outage.

What additional information do you need from customer in order to recommend a suitable migration method? Choose two

• Elapsed time since database was last patched

• On-premises host operating system and version

• Number of active connections

• Data types used in the on-premises database

• Top 5 longest running queries

A cloud consultant is working on implementation project on OCI. As part of the compliance requirements, the objects placed in object storage should be automatically archived first and then deleted. He is testing a Lifecycle Policy on Object Storage and created a policy as below: [ { "name": "Archive_doc", "action": "ARCHIVE", "objectNameFilter": { "inclusionPrefixes": "doc"] }, "timeAmount": 5, "timeunit": "DAYS", "isEnabled": true }, { "name": "Delete_doc", "action": "DELETE", "objectNameFilter": "inclusionPrefixes": [ "doc"] 1."timeAmount": 5, "timeunit": "DAYS", "isEnabled": true } What will happen after this policy is applied?

• All objects with names starting with "doc" will be deleted after 5 days of object creation

• All the objects having file extension ".doc" will be archived for 5 days and will be deleted 10 days after object creation

• All the objects having file extension ".doc" will be archived 5 days after object creation

• All the objects with names starting with "doc" will be archived 5 days after object creation and will be deleted 5 days after archival

A FinTech startup is developing a new blockchain based application to provide Smart Contracts using micro-services architecture. The development team is planning to deploy the application using containers and looking for a reliable way to build, deploy and manage their cloud-native application. Additionally, they need an easy way to store, share and manage their application artifacts.

Which option should you recommend for this application?

• Install and manage a Kubernetes cluster on OCI Compute Instances and use OCI Resource Manager for management of application artifacts

• Use and OCI Resource Manager to manage cloud-native application and make the application artifacts available using OCI Functions

• Use Oracle Container Engine for Kubernetes (OKE) to manage of cloud-native applications and OCI Registry for application artifacts

• Use Oracle Container Engine for Kubernetes (OKE) to manage the deployment environment and OCI Functions for application artifacts

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?

• Delete the running instance and spin up a new instance with the desired shape.

• Change the shape of instance without reboot, but stop all the applications running on instance beforehand to prevent data corruption.

• Change the shape of the virtual machine instance using the Change Shape feature available in the console.

• OCI doesn't allow such an operation.

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?

• Create a vault, import your master encryption key into the vault, generate data encryption key, assign data encryption key to the block volume

• 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

• Create a vault, create a master encryption key in the vault, assign this master encryption key to the block volume

• 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 part of a project team working in the development environment created in OCI. You have realized that the CIDR block specified for one of the subnet in a VCN is not correct and want to delete the subnet. While deleting you are getting an error indicating that there are still resources that you must delete first. The error includes the OCID of the VNIC that is in the subnet.

Which of the following action you will take to troubleshoot this issue?

• Use OCI CLI to call "GetVnic" operation to find out the parent resource of the VNIC

• Copy and Paste OCID of the VNIC in the search box of the OCI Console to find out the parent resource of the VNIC
