You are tasked with building a highly available, fault tolerant web application for your current employer. The security team is concerned about an increase in malicious web- based attacks across the internet and asked what you can do to add a higher level of security to the website.

How should you architect the solution on Oracle Cloud Infrastructure (OCI) to meet all requirements defined by your organization? (Choose the best answer.)

A. Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Deploy a Web Application Firewall (WAF) and configure the load balancer public IP address as the origin.

B. Deploy at least 3 web application servers, each in a different fault domain, using a regional private subnet. Place a public load balancer in a regional public subnet and create a backend set for all of the web application servers. Create a Geolocation steering policy in Traffic Management and add an answer pool that directs to the public IP address of the load balancer. Configure a global catch-all rule to use this answer pool.

C. Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Ensure that each web application server is assigned a public IP address. Deploy a Web Application Firewall (WAF) and configure one Origin for each public IP address.

D. Deploy at least 3 web application servers, each in a different fault domain, using a regional public subnet. Use the OCI Traffic Management service to create a load balancing policy that will resolve DNS evenly between all web servers.

A fast growing E-commerce company has deployed their online shopping application on Oracle Cloud Infrastructure. The application was deployed on compute instances with Autoscaling configuration for application servers fronted by a load balancer and OCI Autonomous Transaction Processing (ATP) in the backend. In order to promote their e- commerce platform 50% discount was announced on all the products for a limited period. During the day 1 of promotional period it was observed that the application is running slow and company's hotline is flooded with complaints.

What could be two possible reasons for this situation?

A. The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation.

B. As part of Autoscaling, the load balancer shape has dynamically changed to a larger shape to handle more incoming traffic and the system was slow for a short time during this change.

C. The health check on some of the backend servers has failed and the load balancer was rebooting these servers.

D. Autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room for scaling further.

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. Use SSH to connect to the public: IP address of the compute Instance and provide the console connection OCID as the username.

B. edit the Linux boot menu to enable access to console.

C. Use SSH to connect to the service endpoint of the console connection service

D. Reboot the compute instance using the Oracle Cloud Infrastructure (OCI) Management Console

E. Upload an API signing key for console connection authentication.

F. Stop the compute Instance using the Oracle cloud Infrastructure (OCI) Command Line interface (CLI).

You are responsible for migrating your on-premises legacy databases on 11.2.0.4 version to Autonomous Transaction Processing - Dedicated (ATP-D) in Oracle Cloud Infrastructure (OCI). As a solution architect, you need to plan your migration approach.

Which three options do you need to implement together to migrate your on-premises databases to OCI?

A. Retain all legacy structures and unsupported features (e.g. legacy LOBs) in the on- premises databases for migration.

B. Use Oracle Data Guard to keep on-premises database always active during migration.

C. Launch Autonomous Transaction Processing - Dedicated database in OCI.

D. Retain changes to Oracle shipped privileges, stored procedures or views in the on- premises databases.

E. Convert on-premises databases to PDB, upgrade to 19c, and encrypt.

F. Use Oracle GoldenGate replication to keep on-premises database online during migration.

An Oracle Cloud Infrastructure (OCI) Public Load Balancer's SSL certificate is expiring soon. You noticed the Load Balancer is configured with SSL Termination only. When the certificate expires, data traffic can be interrupted and security compromised.

What steps do you need to take to prevent this situation?

A. Add the new SSL certificate to the Load Balancer, update backend servers to work with a new certificate and edit listeners so they can use the new certificate bundle.

B. Add the new SSL certificate to the Load Balancer, update listeners and backend sets so they can use the new certificate bundle.

C. Add the new SSL certificate to the Load Balancer and implement end to end SSL so it can encrypt the traffic from clients all the way to the backend servers.

D. Add the new SSL certificate to the Load Balancer and update backend servers to use the new certificate bundle.

E. Add the new SSL certificate to the Load Balancer and update listeners to use the new certificate bundle.

A startup company is looking for a solution for processing of data transmitted by the IOT devices fitted to transport vehicles that carry frozen foods. The data should be consumed and processed in real time. The processed data should be archived to OCI Object Storage bucket. and use Autonomous Data warehouse (ADW) to handle analytics.

Which architecture will help you meet this requirement?

A. Use OCI Streaming Service to collect the incoming biometric data. Use an open source Hadoop cluster to analyze the data horn streaming service. Store the results to OCI Autonomous Data warehouse (ADW) to handle complex analytics

B. Use OCI Streaming Service to collect the incoming biometric data. Use Oracle Functions to process the date and show the results on a real-time dashboard and store the results lo OCI Object Storage Store the data In OCI Autonomous Data warehouse (ADW) to handle analytics.

C. Create an OCI Object Storage bucket to collect the incoming biometric data from the smart pet collar Fetch the data horn OC\ Object storage to OCI Autonomous Data Warehouse (ADW) every day and run analytics Jobs with it
