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.

You have decided to migrate your application to Oracle Cloud Infrastructure and use Oracle Functions to deploy your microservices.

Which monitoring metrics are available to help you calculate your total cost for using Oracle Functions per month? (Choose Two)

A. Amount of RAM used by your functions.

B. Length of time a function runs.

C. Number of times a function is invoked.

D. Amount of storage used by your functions.

E. Network bandwidth used by your functions.

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?

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

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

C. Use OCI CLI to delete the VNIC first and then delete the subnet

D. Use OCI CLI to delete the subnet using --force option

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?

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

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

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

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

A large financial services company has used 2 types of Oracle DB Systems. In Oracle Cloud Infrastructure (OCI) to store user data. One is running on a VM.Standard2.8 shape and the other on a VM.Standard 2.4 shape.

As business grows, data is growing rapidly on both the databases and performance is also degrading. The company wants to address this problem with a viable and economical solution.

As the solution architect for that company you have suggested that they move their databases to Autonomous Transaction Processing Serverless (ATP-S) database.

Which two factors should you consider before you arrived at that recommendation?

C. Confirm that ATP-S allows customers to compress tablespaces to reduce storage costs

D. Upon provisioning, ATP-S automatically scales up CPU to meet the application's processing requirements.

A global media organization is working on a project which lets users upload their videos on their site. After upload is complete, the video should be automatically processed by an Al algorithm. The algorithm will try to recognize actions in the videos so that it can be used to show related advertisements in future.
