Explanation: Deploy a 2 -node Oracle RAC on VMs in the primary region and utilize Oracle GoldenGate for real -time data replication to a 2 -node Oracle RAC on VMs in a secondary region. -> Correct. Deploy a 2 -node Oracle RAC on VMs in the primary region and utilize Oracle GoldenGate for real -time data replication to a 2-node Oracle RAC on VMs in a secondary region. This approach efficiently meets the stringent RPO and RTO by leveraging Oracle GoldenGate's capabilities for real-time data replication and Oracle RAC's high availability features, ensuring operational continuity across regions. Implement a single -instance Oracle database on a VM in the primary region, with Oracle Active Data Guard for real-time data replication to a single -instance Oracle database on a VM in a secondary region. -> Incorrect. While Oracle Active Data Guard supports real-time replication, a single -instance database may not provide the high availability and fast failover capabilities required to meet the RTO and RPO targets. Set up a 2-node Oracle Real Application Clusters (RAC) on VMs within a single availability domain, and use Oracle Active Data Guard to replicate data to a 2-node Oracle RAC in a different availability domain in the same region. -> Incorrect. This setup offers high availability within the same region but may not sufficiently protect against regional outages, potentially compromising the platform's disaster recovery requirements. Establish a 3 -node Oracle RAC on bare metal instances in the primary region, manually configuring Oracle Data Guard for synchronous replication to a 3 -node Oracle RAC on bare metal instances in a secondary region. -> Incorrect. A 3-node Oracle RAC on bare metal provides excellent performance and availability but may exceed the cost -efficiency criteria due to the high resource and management overhead involved in such a deployment. You are tasked with ensuring the continuous operation and optimal performance of the company's database infrastructure in Oracle Cloud Infrastructure (OCI). The corporation's database landscape includes Oracle Autonomous Transaction Processing (ATP), Oracle Autonomous Data Warehouse (ADW), and MySQL Database Service. Recently, users have reported intermittent slow response times from applications using these databases, particularly during weekly financial reporting activities. Your preliminary analysis indicates that the issues are related to database performance. Which of the following steps would you prioritize to diagnose and resolve the performance bottlenecks?
Use of API Gateways only within OCI -> Incorrect. While API gateways are crucial for managing APIs and can facilitate secure data exchange, relying solely on API Gateways within OCI does not directly achieve seamless connectivity with services in another cloud provider’s environment. A solutions architect is designing a multi -tier web application on Oracle Cloud Infrastructure (OCI) that requires a database tier to be accessible only from the application server tier within the same Virtual Cloud Network (VCN). The architect is evaluating the best approach to secure the database tier from unauthorized access while ensuring connectivity from the application servers. Which of the following configurations would best achieve these requirements?
B. Implement a single -node VM Oracle database in the primary region and use Oracle GoldenGate for real-time data replication to a similar setup in a secondary region. C. Deploy a 2-node Oracle Real Application Clusters (RAC) in one availability domain and use Oracle Active Data Guard to replicate the database to another 2 -node Oracle RAC in a different availability domain within the same region. D. Utilize an Autonomous Database with Data Guard for real-time data replication across two different regions, ensuring automatic failover and backup. Explanation: Implement a single -node VM Oracle database in the primary region and use Oracle GoldenGate for real- time data replication to a similar setup in a secondary region. -> Correct. Implement a single -node VM Oracle database in the primary region and use Oracle GoldenGate for real -time data replication to a similar setup in a secondary region. This approach offers a good balance between cost and the ability to meet the specified RTO and RPO by leveraging Oracle GoldenGate for efficient real -time data replication and high availability across regions. Deploy a 2 -node Oracle Real Application Clusters (RAC) in one availability domain and use Oracle Active Data Guard to replicate the database to another 2 -node Oracle RAC in a different availability domain within the same region. -> Incorrect. While offering high availability within the same region, this option may not efficiently address the inter -region RPO and RTO requirements due to its intra -region limitation. Utilize an Autonomous Database with Data Guard for real-time data replication across two different regions, ensuring automatic failover and backup. -> Incorrect. An Autonomous Database with Data Guard provides high availability and automatic failover but may exceed the required budget and complexity for real -time replication across regions for gaming databases. Set up a single -instance Oracle database on a VM in one region and manually export database backups to Oracle Cloud Infrastructure Object Storage, with backups replicated across regions for disaster recovery. -> Incorrect. This manual backup and restore approach cannot meet the required RTO and RPO due to the time it takes to perform backups, transfer them across regions, and restore operations. A global financial services firm is planning to migrate a complex, regulated workload consisting of high - volume transactional databases, customer -facing applications, and batch processing systems to Oracle Cloud Infrastructure (OCI) to improve resilience and scalability. Given the stringent regulatory compliance and zero data loss requirements, what two steps should be emphasized in their migration plan using Oracle Cloud Migrations to ensure a seamless transition?
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.
