Deploy the payment processing system on bare metal servers in a single OCI Availability Domain, using physical firewalls for security and manual scaling techniques to handle peak loads. -> Incorrect. The use of bare metal servers in a single AD and reliance on manual scaling and physical firewalls does not provide the scalability, security, or disaster recovery capabilities necessary for a critical fintech application. Your company is planning to migrate its on-premises applications to Oracle Cloud Infrastructure (OCI) and aims to implement a disaster recovery strategy that ensures high availability and data durability. Which of the following would be the most appropriate solution to achieve this goal?
single instance in only the home region does not address the requirement for high availability and low latency globally. Manually provision infrastructure in each region through the OCI Console to ensure precise control over resources. -> Incorrect. Manual provisioning contradicts the requirement for automation using Infrastructure -as-Code and can lead to inconsistencies and errors across regions. Implement OCI Functions for serverless execution of the application to automatically scale without provisioning infrastructure. -> Incorrect. Although OCI Functions provide scalability and serverless execution, they may not meet all requirements of complex applications that require specific infrastructure configurations. A multinational finance corporation is planning to deploy a secure, highly available application for real- time stock trading. This application needs to automatically scale based on the stock market activity, provide minimal latency for global users, and ensure data integrity and security for all transactions. Which combination of Oracle Cloud Infrastructure (OCI) services would best support these requirements?
Explanation: RTO and RPO objectives -> Correct. RTO and RPO are critical for determining the disaster recovery strategy's objectives, focusing on minimizing downtime and data loss. Replication frequency -> Correct. The frequency of replication is key to achieving the desired RPO, affecting how current the backup data will be at the time of a disaster. Data residency requirements -> Incorrect. While data residency is important, it is more related to compliance and data governance rather than the technical aspects of disaster recovery planning. Network bandwidth -> Incorrect. Network bandwidth affects performance but is a secondary consideration to the replication strategy's foundational elements. Testing frequency -> Incorrect. Testing frequency is crucial for ensuring the plan's effectiveness over time but is not a foundational consideration in the initial planning stage. A multinational corporation plans to expand its data analytics capabilities by integrating its existing on - premises VMware -based applications with Oracle Cloud Infrastructure (OCI) to leverage OCI's advanced analytics services. The goal is to create a seamless, scalable hybrid cloud environment that enables data to be efficiently processed and analyzed between on -premises and OCI. Which of the following designs using Oracle Cloud VMware Solution best achieves this integration while ensuring data security and compliance?
A multinational company has recently deployed a mission -critical application on Oracle Cloud Infrastructure (OCI) that spans multiple regions to ensure high availability and disaster recovery. Despite the successful deployment, they are experiencing intermittent connectivity issues between their application components, which are affecting performance. As an OCI Architect, you are tasked with identifying the root cause and implementing a solution. Which of the following approaches would most effectively resolve the connectivity issues?
Database with TDE for encryption, and federating OCI IAM with the existing identity management system for access control, implementing network security groups for geographic and time-based access rules. B. Implementing a custom application on Oracle Kubernetes Engine (OKE), using OCI Vault for key management, OCI IAM for authentication and authorization, and a third -party service for geolocation - based access control. C. Deploying data on OCI Object Storage with server -side encryption enabled and using OCI Identity and Access Management (IAM) for access control. D. Utilizing Oracle Autonomous Database with Transparent Data Encryption, and integrating with OCI IAM for access control, enhanced with custom policies for geographic and time -based restrictions. Explanation: Utilizing OCI's Virtual Cloud Network (VCN) with a Service Gateway for secure connectivity, Oracle Database with TDE for encryption, and federating OCI IAM with the existing identity management system for access control, implementing network security groups for geographic and time -based access rules. -> Correct. This solution provides comprehensive coverage for encryption at rest (TDE) and in transit (VCN's secure connectivity), integrates seamlessly with existing identity management systems via IAM federation, and uses network security groups to enforce geographic and time -based access controls. Deploying data on OCI Object Storage with server -side encryption enabled and using OCI Identity and Access Management (IAM) for access control. -> Incorrect. While this solution encrypts data at rest and integrates with IAM for access control, it does not natively offer geographic and time -based access controls or specify encryption in transit. Utilizing Oracle Autonomous Database with Transparent Data Encryption, and integrating with OCI IAM for access control, enhanced with custom policies for geographic and time -based restrictions. -> Incorrect. This approach covers encryption at rest and in transit and integrates with IAM. However, implementing custom policies for geographic and time -based restrictions would require additional solutions, as these are not directly supported features of the Autonomous Database or IAM. Implementing a custom application on Oracle Kubernetes Engine (OKE), using OCI Vault for key management, OCI IAM for authentication and authorization, and a third -party service for geolocation - based access control. -> Incorrect. This approach offers flexibility and covers most requirements, including encryption and integration with IAM. However, the complexity and potential gaps in using a third-party service for specific access control do not make it the best solution. A global logistics company is looking to enhance its supply chain management system by implementing a solution on Oracle Cloud Infrastructure (OCI) that integrates real -time tracking, predictive analytics, and automated inventory management. The system must ensure data accuracy, high availability, and secure access across multiple geographic locations. Which two actions should the company take to implement and operate this solution effectively in OCI?
intervals. C. Implement OCI Functions to trigger data copy operations based on a scheduled time. D. Configure a Virtual Cloud Network (VCN) peering between regions to facilitate data replication. Explanation: Use cross -region replication to automatically replicate data across regions. -> Correct. Cross -region replication is a native feature of OCI Object Storage that automatically and asynchronously replicates data across regions, ensuring high availability and disaster recovery without the need for custom solutions. Deploy a custom application on compute instances in each region to manually copy data at regular intervals. -> Incorrect. While feasible, this method is more complex and error -prone compared to using built-in OCI features designed for this purpose. Implement OCI Functions to trigger data copy operations based on a scheduled time. -> Incorrect. OCI Functions can automate tasks, but for data replication across regions, OCI's native cross -region replication is more efficient and less complex. Configure a Virtual Cloud Network (VCN) peering between regions to facilitate data replication. -> Incorrect. VCN peering allows for network connectivity between regions but does not directly facilitate or automate data replication. Your organization is planning to leverage Oracle Cloud Infrastructure (OCI) for hosting a new, critical web application that demands high scalability and performance. To meet these requirements, you are considering various OCI services and features for the deployment strategy. Which of the following options is not an appropriate use of OCI services for optimizing the scalability and performance of the web application?
