An online registration system Is currently hosted on one large Oracle Cloud Infrastructure (OCT) Bare metal compute Instance with attached block volume to store of the users' dat. The registration system accepts the Information from the user, Including documents and photos then performs automated verification and processing to check it the user is eligible for registration. The registration system becomes unavailable at tunes when there is a surge of users using the system the existing architecture needs improvement as it takes a long time for the system to complete the processing and the attached block volumes are not large enough to use data being uploaded by the users. Which Is the most effective option to achieve a highly scalable solution?

A. Attach more Block volumes as the data volume increase, use Oracle Notification Service (ONS) to distribute tasks to a pool of compute instances working In parallel, and Auto Scaling to dynamically size the pool of Instances depending on the number of notifications received from the Notification Service. Use Resource Manager stacks to replicate your architecture to another region.

B. Change your architecture to use an OCI Object Storage standard tier bucket, replace the single bare metal instance with a Oracle Streaming Service (OSS) to ingest the Incoming requests and distribute

the tasks to a group of compute Instances with Auto Scaling

C. Upgrade your architecture to use a pool of Bare metal servers and configure them to use their local SSDs for faster data access Set up Oracle Streaming Service (OSS) to distribute the tasks to the pool of Bare metal Instances with Auto Scaling to dynamically increase or decrease the pool of compute instances depending on the length of the Streaming queue.

D. Upgrade your architecture to use more Block volumes as the data volume Increases. Replace the single bare metal instance with a group of compute instances with Auto Scaling to dynamically increase or decrease the compute instance pools depending on the traffic.

A hospital in Austin has hosted its web based medical records portal entirely In Oracle cloud Infrastructure (OCI) using Compute Instances for its web-tier and DB system database for its data tier. To validate compliance with Health Insurance Portability and Accountability (HIPAA), the security professional to check their systems it was found that there are a lot of unauthorized coming requests coming from a set of IP addresses originating from a country in Southeast Asia. Which option can mitigate this type of attack?

A. Block the attacking IP address by creating by Network Security Group rule to deny access to the compute Instance where the web server Is running

B. Block the attacking IP address by implementing a OCI Web Application Firewall policy using Access Control Rules

C. Mitigate the attack by changing the Route fable to redirect the unauthorized traffic to a dummy Compute instance

D. Block the attacking IP address by creating a Security List rule to deny access to the subnet where the web server Is running

You have multiple IAM users who launch different types of compute Instances and block volumes every day. As a result, your Oracle cloud Infrastructure (OCF) tenancy quickly hit the service limit and you can no longer create any new instances. As you are cleaning up environment, you notice that the majority of the Instances and block volumes are untagged. Therefore, It is difficult to pinpoint the owner of these resources verify if they are safe to terminate. Because of this, your company has issued a new mandate, which requires adding compute instances. Which option is the simplest way to implement this new requirement?

A. Create a policy to automatically tag a resource with the user name.

B. Create a policy using 1AM requiring users to tag specific resources. This will allow a user to launch compute instances on\y if certain tags were defined.

C. Create tag variables to automatically tag a resource with the user name.

D. Create a default tag for each compartment, which ensure that appropriate tags are applied at resource creation

E. Create tag variables for each compartment to automatically tag a resource with the user name.

You are working as a solutions architect for an online retail store In Frankfurt which uses multiple compute instance VMs spread among three availability domains In the eu-frankfurt-1 region.

You noticed the website Is having very high traffic, so you enabled autoscaling to sun tee me no f your application but, you observed that one of the availability domains is not receiving any traffic. What could be wrong In this situation?

A. Autoscaling only works with single availability domains.

B. You have to manually acid all three availability domains to your load balancer configuration.

C. Autoscaling can be enabled for multiple availability domains only in uk-london t region.

D. Autoscaling is using an Instance Pool configured to create instances in two availability Domains.

E. You forgot to attach a load balancer to your instance pool configuration.

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. The development team wants to focus on writing Al code and don't want to worry about underlying infrastructure for high-availability, scalability, security and monitoring. Which OCI services should you recommend for this project?

A. Use OCI Events service for triggering automatic processing of video, Oracle Container Engine for Kubernetes (OKE) and OCI Digital Assistant

B. Use Oracle Container Engine for Kubernetes (OKE) for deployment of Al Code, OCI Notifications and Object Storage

C. Use OCI Resource Manager to manage the underlying infrastructure, OCI Functions and OCI Events service.

D. Use Object Storage for storing videos, OCI Events service and OCI Functions

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 Group's 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?

A. You are exceeding your volume group backup quota configured.

B. 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.

C. Compute instance with multiple block volumes attached cannot move when a compartment is moved.

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

You are running a legacy application In a compute Instance on Oracle Cloud Infrastructure (OCI).
