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. Autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room for scaling further.
• D. The health check on some of the backend servers has failed and the load balancer was rebooting these servers.

You are working as a solution architect with a global automotive provider who is looking to create a multi-cloud solution. They want to run their application tier in Microsoft Azure while utilizing the Oracle DB Systems in the Oracle Cloud Infrastructure (OCI).
What is the most-fault tolerant and secure solution for this customer? (Choose the best answer.)

• A. Create an encrypted, Virtual Private Network connection between the Microsoft Azure Virtual Network that contains the application tier and the OCI Virtual Cloud Network (VCN) that contains the Oracle Databases.
• B. Use an OCI Virtual Cloud Network remote peering connection to create a remote network connection between the application tier running in Microsoft Azure Virtual Network and Oracle Databases running in the OCI Virtual Cloud Network (VCN).
• C. Create a FastConnect virtual circuit with Microsoft Azure as the provider to establish a private interconnect between the application tier running in the Azure Virtual Network and the OCI VCN that contains the Oracle Databases.
• D. Deploy the Oracle database system into a public subnet in your VCN and assign a public IP address. Connect your application tier running in Azure to the public IP address of the database system over the internet.

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

You work for a retail company and they developed a Microservices based shopping application that needs to access Oracle Autonomous Database from the application. As an Architect, you have been tasked to treat all of the application components as Kubernetes native objects, such as the microservices, Oracle Autonomous database, Kubernetes services, etc.
What should you do to make sure that you can use Kubernetes constructs to manage the life cycle of the application components, including Oracle Autonomous Database? (Choose the best answer.)

• A. Install and secure the OCI Service Broker for Kubernetes. Then provision and bind to the required Oracle Cloud Infrastructure services.
• B. Create a service from the Kubernetes cluster and point to the Oracle Autonomous Database using its FQDN.
• C. Create an Oracle Cloud Infrastructure (OCI) Service Gateway and connect to the Oracle Autonomous Database using the private IP address from the microservice.
• D. Provision an Oracle Autonomous Database and then use OCI Service Broker to access the database as a native component to your Kubernetes cluster.
