A global retailer has decided to re-design its e-commerce platform to have a micro-services architecture. They would like to decouple application architecture into smaller, independent services using Oracle Cloud Infrastructure (OCI). They have decided to use both containers and servers technologies to run these application instances.
Which option should you recommend to build this new platform?

• A.Install a kubernetes cluster on OCI and use OCI event service.
• B.Use Oracle Container Engine for kubernetes, OCI Registry and OCI Functions.
• C.Use OCI Resource Manager to automate compute Instances provisioning and use OCI Streaming service.
• D.Use OCI functions, OCI object storage and OCI event service.

Correct Answer: B

Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs.

Oracle Cloud Infrastructure Container Engine for Kubernetes is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud. Use Container Engine for Kubernetes (sometimes abbreviated to just OKE) when your development team wants to reliably build, deploy, and manage cloud-native applications. You specify the compute resources that your applications require, and Container Engine for Kubernetes provisions them on Oracle Cloud Infrastructure in an existing OCI tenancy.

A consulting company that employs Oracle Cloud Infrastructure (OCI) architects has successfully completed resource migration from Microsoft Azure to OCI, and no longer requires the OCI FastConnect circuit to Azure. The project manager has asked you to delete all resources involved in this inter-cloud connectivity. From the Azure side, you delete the Resource Group. After a while, you notice that all Azure resources have been deleted, except for the Azure ExpressRoute circuit.
What could be a potential reason for this issue?

• A.You need to remove the Azure ExpressRoute Partner Service Key from the OCI FastConnect circuit, and then you can delete the ExpressRoute virtual circuit.
• B.Your bill from the OCI side needs to be paid in full before you can remove the Azure ExpressRoute circuit.
• C.You need to remove all routes that point to the inter-cloud connection on both OCI and Azure before you can delete the circuit.
• D.You need to first delete the OCI FastConnect circuit for the ExpressRoute circuit to be decommissioned, and then you can delete the ExpressRoute virtual circuit.

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 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.
• C.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.
• 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 company is running High Performance Computing workloads on Oracle Cloud Infrastructure and are using OCI bare metal compute shape. They have decided to create a custom image of the bare metal instance's boot disk and use it to launch other instances.
Which of the following is a NOT a true statement?

• A.You can create additional custom images of an instance while the instance is engaged in the image creation process.
• B.Custom images do not include the data from any attached block volumes.
• C.Before you create a custom image of an instance, you must disconnect all iSCSI attachments and remove all iscsid node configurations from the instance.
• D.Editing custom Windows images is not supported due to hardware differences between shapes.

Your customer has gone through a recent departmental re structure. As part of this change, they are organizing their Oracle Cloud Infrastructure (OCI) compartment structure to align with the company's new organizational structure.
They have made the following change:
Compartment x Is moved, and its parent compartment is now compartment c.

Policy defined in compartment A: Allow group networkadmins to manage subnets in compartment X Policy defined in root compartment: Allow group admins to read subnets in compartment Finance:A:X After you move the compartment, which two IAM policies would be required to ensure both groups retain the same permissions to compartment X that they had before? (Choose two.)

• A.Define a policy in the root compartment as follows: Allow group admins to read subnets in compartment HR:C:X
• B.Define a policy in compartment C as follows: Allow group networkadmins to read subnets in compartment X
• C.Define a policy in compartment HR as follows: Allow group networkadmins to manage subnets in compartment C:X.
• D.Define a policy in the root compartment as follows: Allow group admins to manage subnets in compartment Finance:A:X
