Oracle 1Z0-997-20 valid study dumps : Oracle Cloud Infrastructure 2020 Architect Professional

You are working with a social media company as a solution architect. The media company wants to collect and analyze large amounts of data being generated from their websites and social media feeds to gain insights and continuously improve the user experience. In order to meet this requirement, you have developed a microservices application hosted on Oracle Container Engine for Kubernetes. The application will process the data and store the result to an Autonomous Data Warehouse (ADW) instance.
Which Oracle Cloud Infrastructure (OCI) service can you use to collect and process a large volume of unstructured data in real time?

• A. OCI Notifications
• B. OCI Streaming
• C. OCI Events
• D. OCI Resource Manager

An upcoming e-commerce company has deployed their online shopping application on OCI. 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. 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
• B. The health check on some of the backend servers has failed and the load balancer was rebooting these servers.
• C. The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation
• D. The autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room of scaling

You are tasked with migrating an online shopping website to Oracle Cloud Infrastructure (OCI) and decide to use a Load Balancer. You have configured the backend set with the round robin policy. During the testing phase, you noticed that users are losing items from their shopping carts when they navigate to different pages.
How should you implement a solution to this problem?

• A. Set up session persistence at the Load Balancer backend set.
• B. Replace the round robin policy with least connections policy at the backend set.
• C. Set up a Traffic Management Steering Policy to redirect traffic to a different backend set that is deployed exclusively for the purpose of holding all Items placed in the shopping cart.
• D. Configure a set of path route rules that will route to different backend sets based on the URI requested by the customer's browser.

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. Network bandwidth used by your functions.
• B. Number of times a function is invoked.
• C. Length of time a function runs.
• D. Amount of storage used by your functions.
• E. Amount of RAM used by your functions.

Which of the following features is NOT supported by Oracle Cloud Infrastructure Multi-factor authentication (MFA)?

• A. Users can disable MFA for their own accounts.
• B. Only the user can enable MFA for their own account.
• C. Members of the Administrators group can disable MFA for other users.
• D. Members of the Administrators group can enable MFA for other users.
