In a leading e -commerce company, you are tasked with managing and optimizing the database architecture within Oracle Cloud Infrastructure (OCI) to support both high transaction volumes and analytical processing for real -time business intelligence. The current setup involves Oracle Autonomous Transaction Processing (ATP) for transactional data, Oracle Autonomous Data Warehouse (ADW) for analytics, and MySQL Database Service for specific microservices. Recently, you've noticed a decline in transaction processing speeds and report generation times, particularly during peak sales events. Initial investigations point towards inefficient resource allocation and potential database configuration issues. Which of the following strategies would most effectively diagnose and resolve the identified performance bottlenecks?
OCI region. Use OCI Object Storage to store replication logs. D. Create a custom script to export database changes every 4 hours to OCI Object Storage, and use OCI Functions to automate the process of updating a secondary database in another region with these changes. Explanation: Create a custom script to export database changes every 4 hours to OCI Object Storage, and use OCI Functions to automate the process of updating a secondary database in another region with these changes. -> Correct. This approach allows for the efficient and cost -effective replication of database changes to a secondary database in another region, meeting the RPO and disaster recovery requirements. Custom scripting combined with OCI Functions for automation offers flexibility and control over the disaster recovery process, aligning with the scenario's requirements for efficiency and cost - effectiveness. Utilize OCI Block Volume backups to periodically back up the entire database every 4 hours. Store backups in the same region but in a different availability domain. -> Incorrect. While OCI Block Volume backups provide a way to back up data, backing up the entire 2TB database every 4 hours is not practical or cost -effective, and storing backups in the same region does not protect against regional outages. Configure Data Guard with the primary database in one region and the standby database in a different region. Set up automatic failover for high availability. -> Incorrect. Data Guard provides high availability and data protection for Oracle databases, but it might not be the most cost -effective for the given RPO and does not necessarily address the requirement for disaster recovery across regions with the specified details. Implement Oracle GoldenGate for real-time data replication to a secondary database in a different OCI region. Use OCI Object Storage to store replication logs. -> Incorrect. Oracle GoldenGate offers real - time data replication, which could meet the RPO requirement but may not be the most cost -effective solution due to the complexity and licensing costs associated with real -time replication for disaster recovery purposes. A cloud architect is designing a highly available application in Oracle Cloud Infrastructure (OCI). The application needs to maintain high availability and automatic failover across different availability domains within a region. Which of the following is not a correct approach to achieve this requirement?
Deploying application instances in multiple availability domains and using OCI Load Balancer to distribute traffic across instances. -> Incorrect. This is a standard practice for achieving high availability, as the OCI Load Balancer can distribute traffic across multiple availability domains to ensure continued service even if one availability domain fails. Deploy application -specific failover mechanisms, such as database replication or application clustering, across multiple availability domains. -> Incorrect. This approach ensures that if one instance of the application fails or becomes inaccessible, other instances can take over without manual intervention. It leverages OCI's capabilities to automatically reroute traffic and operations to healthy instances in other availability domains, maintaining the application's availability. Implementing OCI's Autonomous Database in a multi -AD configuration to ensure database services remain available even if one availability domain goes down. -> Incorrect. OCI's Autonomous Database supports deployment across multiple availability domains, providing built -in high availability and data protection. Your company plans to enhance the security posture of its applications deployed on Oracle Cloud Infrastructure (OCI). The goal is to ensure that all traffic to the application's public endpoints is inspected and malicious traffic is blocked. Which configuration achieves this objective?
web servers and the database. What is the most effective OCI feature to implement this security requirement?
OCI Object Storage, OCI Streaming, and Oracle Container Engine for Kubernetes -> Incorrect. Misses out on specific services like OCI Data Science for machine learning and OCI Vault for enhanced security, which are crucial for the project's needs. A healthcare company aims to leverage Oracle Cloud Infrastructure (OCI) to deploy a critical application that adheres to regulatory compliance regarding data residency and redundancy. As the lead solution architect, you need to ensure that the application's data is stored across multiple geographical locations to meet compliance requirements while maintaining data availability. Which of the following strategies would not meet the company's requirements for data residency and redundancy?
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?
