Which of the following is NOT a good use case for the Oracle Cloud Infrastructure (OCI) Streaming service?

• Meeting compliance requirements for data to remain unchanged over a long time, so that it can be retrieved for audit purposes.

• Messaging with a pull-based communication model and the ability to feed multiple consumers with the same data independently.

• Ingesting metric and log data to help make critical operational data more quickly available for indexing, analysis, and visualization.

• Providing a unified entry point for cloud components to report their life cycle events for audit, accounting, and related activities.

Which of the following is NOT a good use case for using the functionality available in the Oracle Cloud Infrastructure (OCI) Events service?

• Publish all events in a specific compartment to Oracle Streaming service for later analysis.

• Triggers Function using Oracle Functions when new files are uploaded in an OCI Object Storage bucket.

• Publish a notification when long lived tasks complete, such as OCI Autonomous Database backup completion.

• Capture Monitoring Alarms and invoke Autoscaling of compute instances.

• Trigger a notification when a function completes its execution.

You have deployed a multi-tier application with multiple compute instances in Oracle Cloud Infrastructure. You want to back up these volumes and have decided to use 'Volume Groups' feature. The Block volume and Compute instances exist in different compartments within your tenancy. Periodically, a few child compartments are moved under different parent compartments, and you notice that sometimes volume group backup fails.

What could be the cause?

• The Identity and Access Management policy allowing backup failed to move when the compartment was moved.

• You are exceeding your volume group backup quota configured.

• You have the same block volume attached to multiple compute instances; if these compute instances are in different compartments then all concerned compartments must be moved at the same time.

• A compute instance with multiple block volumes attached cannot move when a compartment is moved.

A global media organization is working on a project which lets users upload their videos to the site. After upload is complete, the video should be automatically processed by an Al algorithm. The algorithm will try to recognize certain actions in the videos so that it can be used to show related advertisements in future. The development team wants to focus on writing Al code and not worry about underlying infrastructure for high availability, scalability, security and monitoring.

Which Oracle Cloud Infrastructure (OCI) services would meet these requirements?

• OCI Object Storage, OCI Events service and OCI Functions.

• Oracle Container Engine for Kubernetes, OCI Notifications and OCI Object Storage.

• OCI Events, Oracle Container Engine for Kubernetes and OCI Digital Assistant.

• OCI Resource Manager, OCI Functions and OCI Events service.

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)

• Amount of RAM used by your functions.

• Length of time a function runs.

• Number of times a function is invoked.

• Amount of storage used by your functions.

• Network bandwidth used by your functions.

As a solution architect, you are designing a web application to be deployed across multiple Oracle Cloud Infrastructures (OCI) regions for a global audience. Your goal is that users from each region should access the application web servers deployed in their own geographical OCI location.

Which OCI feature can be used to achieve this?

• OCI Traffic Management IP Prefix steering policy

• OCI Global Load balancers

• OCI Public Load Balancers

• OCI Traffic Management GeoLocation steering policy

You are tasked with backing up your data using Oracle Cloud Infrastructure Block Volume service. When you are finalizing your block volume backup schedule, which of the following two are valid considerations for your backup plan? (Choose Two)

• Number of stored backups: How many backups you need to keep available and the deletion schedule for those you no longer need.

• Governance: Tagging of backups so you can capture backup related API calls through the Audit service.

• Frequency: How often you want to back up your data.

• Location: Determine the Object Store Bucket where the backups will be stored.

• Encryption: Whether to use your own key to encrypt your volume backups.

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?

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

• 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.

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

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

An online gaming application is deployed to multiple Availability Domains in the Oracle Cloud Infrastructure (OCI) us-ashburn-1 region. Considering the high volume of traffic that the gaming application handles, the company has hired you to ensure that the data stored by the application is scalable, highly available, and disaster resilient. In the event of failure, the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) must be less than 2 hours. Which Disaster Recovery strategy should be used to achieve the RTO and RPO requirements in the event of a system failure?

• Configure hourly block volumes backups using the OCI Command Line Interface (CLI).

• Create a user defined backup policy with a schedule of generating daily backups for block volumes.

• Configure hourly block volumes backups through the OCI Storage Gateway service.

• Create a user defined backup policy with a schedule of generating hourly backups for block volumes.

You are building a demo for a customer that showcases Oracle Cloud Infrastructure (OCI) Events service and Oracle Functions. You plan to create an event every time an image is uploaded to an OCI Object Storage bucket. You have also created a function that is listening to the event and processes the image for face recognition.

Choose the two actions from below that are NOT required to run the demo successfully.

• You must specify an action type while creating an Event service and specify the function you want to trigger.

• Creating an event rule is not permitted for OCI Object storage.

• The function must be deployed only to Oracle Kubernetes Engine (OKE).

• You have to enable Object Storage buckets to emit events for state changes.

• You must deploy the function that does facial recognition for the demo to work.
