critical web application that requires high availability (HA) and robust disaster recovery (DR) capabilities. Which of the following architectural designs would most effectively meet these requirements?
Develop custom scripts using the OCI CLI to automate the deployment and management of infrastructure, integrating security tools for compliance checks during the deployment process. -> Incorrect. Custom CLI scripts can automate tasks but lack the declarative approach, state management, and comprehensive compliance enforcement capabilities offered by Terraform, making this method less efficient and more prone to errors. Leverage Ansible for automation, using its procedural style to script the infrastructure setup and configuration, including the setup of encryption and auto-scaling rules. -> Incorrect. Ansible is powerful for configuration management and automation but lacks native support for state management and declarative infrastructure as code, which are crucial for complex, compliance -heavy deployments in cloud environments. Your company is planning to deploy a multi -tier web application in Oracle Cloud Infrastructure (OCI) that will handle sensitive customer data. You have been provided with the application architecture, security requirements, expected load, and data governance policies. To design a secure, scalable, and compliant infrastructure, which two additional pieces of information are critical to obtain from your company?
leverage OCI services to ensure data security, high availability, and compliance with healthcare standards. Which of the following is not a true statement regarding best practices for deploying the EHR system on OCI?
that all data relationships and integrity constraints are preserved in OCI. The geographical distribution of the content consumers. -> Correct. Knowing where the consumers are located is important for selecting the right OCI regions and data centers to minimize latency and optimize content delivery performance. The frequency of content backup and archival. -> Incorrect. While important for disaster recovery planning, it's not directly relevant to choosing the migration strategy but rather to post -migration operational considerations. Details of the third -party services integrated with the CMS. -> Incorrect. Integration details are key for operational functionality but are secondary to understanding how to migrate the CMS's core components and data. Average session duration and user engagement metrics. -> Incorrect. User engagement metrics are valuable for performance tuning and capacity planning but do not fundamentally influence the initial migration strategy. GlobalTech Inc. is optimizing their application deployment strategy on Oracle Cloud Infrastructure (OCI) to improve resilience and uptime. They seek a strategy that not only distributes their application instances across multiple OCI Availability Domains but also provides automatic failover and scaling based on demand. Which of the following OCI features should they implement?
D. Utilizing OCI Autoscaling to dynamically adjust the number of Compute instances based on the load, with instances distributed across multiple Availability Domains. Explanation: Utilizing OCI Autoscaling to dynamically adjust the number of Compute instances based on the load, with instances distributed across multiple Availability Domains. -> Correct. This strategy leverages OCI Autoscaling to automatically scale Compute resources in response to real -time demand, ensuring application responsiveness and availability. Distributing instances across multiple Availability Domains enhances fault tolerance and high availability without unnecessary cost accumulation, striking a balance between efficiency, scalability, and cost -effectiveness. Deploying all application tiers on a single large OCI Compute instance to simplify management, relying on manual scaling during peak loads. -> Incorrect. Deploying all tiers on a single large Compute instance may simplify management but lacks scalability and high availability. This approach risks significant downtime and performance degradation during peak loads or in the event of a single point of failure. Implementing stateful components of the application on OCI Functions to leverage serverless computing for all tiers of the application. -> Incorrect. While OCI Functions provide a serverless environment that can scale automatically, using them for stateful components of a multi -tier application can be challenging due to the stateless nature of serverless computing, potentially leading to inefficiencies in application architecture. Configuring a fixed number of Compute instances in a single Availability Domain and using a scheduled scaling policy based on expected load patterns. -> Incorrect. Using a fixed number of instances with scheduled scaling can lead to either resource underutilization during off -peak times or insufficient capacity during unexpected surges, making it a less flexible and potentially cost -inefficient approach. A multinational corporation intends to deploy a new global application in Oracle Cloud Infrastructure (OCI) that requires low latency access for users worldwide, adherence to regional data sovereignty laws, and a robust disaster recovery strategy. The application architecture involves microservices, real -time data analytics, and must ensure data encryption both at rest and in transit. Which of the following implementations would most effectively meet these business and technical requirements?
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?
