You are working as a solution architect for an online retail store to create a portal to allow the users to pay for their groceries using credit cards. Since the application is not fully compliant with the Payment Card Industry Data Security Standard (PCI DSS), your company is looking to use a third party payment service to process credit card payments. The third party service allows a maximum of Spelunk IP addresses 5 public IP addresses at a time However, your website is using Oracle Cloud Infrastructure (OCI) Instance Pool Auto Scaling policy to create up to create up to 15 Instances during peak traffic demand, which are launched In VCN private in VCN private subnets and attached to an OCI public Load Balancer. Upon user payment, the portal connects to the payment service over the Interne! to complete the transaction What solution can you implement to make sure that all compute Instances can connect to the third party system to process the payments aw peak traffic demand?

A. Route credit card payment request from the compute instances through the NAT Gateway. On the third-party services, whitelist the public IP associated with the NAT Gateway.

B. Create an OCI Command Line Interface (CLI) script to automatically reserve public IP address for the compute instances. On the third-party services, whitelist the Reserved public IP.

C. Whitelist the Internet Gateway Public IP on the third party service and route all payment requests through the Internet Gateway.

D. Route payment request from the compute instances through the OCI Load Balancer, which will then be routed to the third party service.

A retail company has several on-premises data centers which span multiple geographical locations. They plan to move some of their applications from on-premises data centers to Oracle Cloud Infrastructure (OCI). For these applications running in OCI, they still need to interact with applications running on their on-premises data centers to Oracle Cloud Infrastructure (OCI). for these applications running in OCI. they still need to interact with applications running on their on-premises data centers. These applications require highly available, fault-tolerant network connections between on premises data centers and OCI. Which option should you recommend to provide the highest level of redundancy?

A. Oracle cloud Infrastructure provides network redundancy by default so that no other operations are required

B. If your data centers span multiple, geographical locations, use only the specific IP address as a static route for the specific geographical location

C. Set up both IPSec VPN and FastConnect to connect your on premises data centers to Oracle Cloud Infrastructure.

D. Use FastConnect private peering only to ensure secure access from your data center to Oracle Cloud Infrastructure

E. Set up a single IPSec VPN connection (rom your data center to Oracle Cloud Infrastructure since It is cost effective

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 the root compartment as follows: Allow group admins to read subnets in compartment HR:C:X

D. Define a policy in compartment C as follows: Allow group networkadmins to read subnets in compartment X

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 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. Amount of RAM used by your functions.

B. Length of time a function runs.

C. Number of times a function is invoked.

D. Amount of storage used by your functions.

E. 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?

A. OCI Traffic Management IP Prefix steering policy

B. OCI Global Load balancers

C. OCI Public Load Balancers

D. 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)

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

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

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

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

E. 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?

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

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

As part of planning the network design on Oracle Cloud Infrastructure, you have been asked to create an Oracle Cloud Infrastructure Virtual Cloud Network (VCN) with 3 subnets, one in each Availability Domain. Each subnet needs to have a minimum of 64 usable IP addresses. What is the smallest subnet and VCN size you should use to implement this design? The requirements are static, so no growth is expected.

A. 122 for the VCN; 124 for the subnets

B. /23 for the VCN; /25 for the subnets

C. /24 for the VCN; /24 for the subnets

D. /22 for the VCN; /25 for the subnets

You have to migrate your application to Oracle Cloud Infrastructure (OCI). The database is constantly being updated and needs to be online without interruptions. How can you transition the database to OCI without interrupting its use?

A. It is impossible to migrate without interruption.

B. Use an on-premises database with two-way synchronization to a cloud-based database and allow clients to connect to either databases.

C. Use an on-premises database with one-way synchronization to a cloud-based database and allow clients to connect only to the cloud database.

D. Use an on-premises database with one-way synchronization to a cloud-based database and allow clients to connect only to the on-premises database until it is synchronized.
