After performing maintenance on an Oracle Linux compute instance the system is returned to a running state You attempt to connect using SSH t to do so. You decide to create an instance console connection to troubleshoot the issue.
Which three tasks would enable you to connect to the console connection and begin troubleshooting?

• A.Stop the compute Instance using the Oracle cloud Infrastructure (OCI) Command Line interface (CLI).
• B.Reboot the compute instance using the Oracle Cloud Infrastructure (OCI) Management Console
• C.Upload an API signing key for console connection authentication.
• D.Use SSH to connect to the public: IP address of the compute Instance and provide the console connection OCID as the username.
• E.Use SSH to connect to the service endpoint of the console connection service
• F.edit the Linux boot menu to enable access to console.

A retail company runs their online shopping platform entirely on Oracle cloud Infrastructure (OCI). This is a 3-tier web application that Includes a Mbps Load Balancer. Virtual Machine Instances for web and an Oracle DB Systems Virtual Machine Due to unprecedented growth, they noticed an Increase in the Incoming traffic to their website and all users start getting 503 (Service Unavailable) errors.
What is the potential problem in this scenario?

• A.You did not configure a Service Gateway to allow connection between web servers and load Balance
• B.The Database Is down hence users can not access the web site
• C.The Traffic Management Policy is not set to load Balancer the traffic to the web servers.
• D.The Load Balancer health check status Indicates critical situation for half of the backend webservers
• E.All the web servers are too busy and not able to answer any request from users.

You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use 'Volume Groups' feature. The Block volume and Compute instances exist in different compartments within your tenancy.
Periodically, a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.
What could be the cause?

• A.You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.
• B.The Identity and Access Management policy allowing backup failed to move when the compartment was moved.
• C.A compute instance with multiple block volumes attached cannot move when a compartment is moved.
• D.You are exceeding your volume group backup quota configured.

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.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.
• B.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.
• C.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.
• D.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.

You work for a German company as the Lead Oracle Cloud Infrastructure architect. You have designed a highly scalable architecture for your company's business critical application which uses the Load Balancer service auto which uses the Load Balancer service, autoscaling configuration for the application servers and a 2 Node VM Oracle RAC database. During the peak utilization period of the- application yon notice that the application is running slow and customers are complaining. This is resulting in support tickets being created for API timeouts and negative sentiment from the customer base.
What are two possible reasons for this application slowness?

• A.Autoscaling configuration for the application servers didn't happen due to service limit breach of the VM shapes used by the application servers
• B.The Load Balancer doesn't have a Network Security Group to allow traffic to the application servers.
• C.Autoscaling configuration for the application servers didn't happen due to compartment quota breach of the VM shapes used by the application servers.
• D.Autoscaling configuration for the application servers didn't happen due to IAM policy that's blocking access to the application server compartment
• E.The Load Balancer configuration is not sending traffic to the listener of the application servers.
