A multinational corporation is planning to migrate its legacy on -premises databases to Oracle Cloud Infrastructure (OCI) to enhance performance, scalability, and disaster recovery capabilities. The corporation's environment consists of a mix of online transaction processing (OLTP) and online analytical processing (OLAP) workloads with strict compliance requirements for data residency and sovereignty. The solution must provide seamless data integration between OLTP and OLAP systems, ensure data encryption both at rest and in transit, and facilitate low -latency access to data across different geographical regions. Which database architecture would best fulfill these requirements?
E. Fault Domains Explanation: Cross -Region Peering -> Correct. Allows private network connectivity across different OCI regions, enhancing disaster recovery capabilities and geographical diversity without exposing data to the public internet. This feature is crucial for maintaining high availability and data replication across regions. Availability Domains -> Correct. Separate data centers within a region. Using multiple availability domains in a region can protect your applications and data from data center failures, essential for high availability within a region. Fault Domains -> Incorrect. Fault domains provide resilience within a single availability domain rather than across regions or availability domains. They are designed to avoid simultaneous failures within the same availability domain. Instance Shape Upgrades -> Incorrect. Upgrading an instance shape mainly affects performance rather than availability or resilience. It's about changing the computing resources for an instance, not about its geographical or infrastructural redundancy. Autonomous Data Warehouse -> Incorrect. It is a specific service focusing on database management with automated backups, updates, and scaling. While important for performance and scalability, it does not directly contribute to geographical resilience or application availability in the context of architecture design. An online retail company is experiencing rapid growth and needs to ensure that its e-commerce platform can scale effectively during high traffic events, such as sales and holidays, while maintaining optimal performance. Which OCI service or feature should they utilize to meet these scalability and performance requirements?
workloads. -> Incorrect. IAM is vital for security and access control but does not contribute to the scalability and performance demands of the application during peak traffic times. OCI Cloud Guard monitors cloud resource configurations and recommends security improvements, which is essential for maintaining a secure environment but does not offer solutions for scaling resources in response to traffic increases. -> Incorrect. Cloud Guard is important for security posture management but does not address the scalability and performance enhancement requirements for the e -commerce platform. Your enterprise plans to deploy a critical web application on Oracle Cloud Infrastructure (OCI) that will handle sensitive customer information. The application will be distributed across multiple OCI regions to ensure high availability and resilience. To maintain data privacy and comply with regulatory requirements, it's imperative that all data transmitted between these regions is encrypted in transit. You have been tasked with designing a solution that ensures encryption across all data transmission paths. Which of the following options would best fulfill the encryption in transit requirements?
requirements?
synchronization. C. Deploy Oracle Autonomous Database in OCI Frankfurt region as the primary database and Oracle Autonomous Database in OCI Dublin region as the standby database, with Data Guard for data synchronization. D. Implement a custom solution using third-party replication software between OCI Frankfurt and OCI Dublin, bypassing Oracle's native technologies for data synchronization. Explanation: Deploy a 2 -node RAC DB System in the OCI Frankfurt region for the primary database and a 2 -node RAC DB System in the OCI Dublin region for the standby database, utilizing Oracle Active Data Guard for data synchronization. -> Correct. This setup provides high availability through RAC and near -zero data loss with Oracle Active Data Guard, meeting the company's RTO and RPO objectives. Deploy a 1 -node VM DB System in OCI Frankfurt region for the primary database and a 1 -node VM DB System in OCI Dublin region for the standby database. Use Oracle Data Guard for data synchronization. -> Incorrect. While this option does use Oracle Data Guard, a 1-node VM DB System may not offer the required high availability and performance for a financial services company. Deploy Oracle Autonomous Database in OCI Frankfurt region as the primary database and Oracle Autonomous Database in OCI Dublin region as the standby database, with Data Guard for data synchronization. -> Incorrect. Oracle Autonomous Database does not use Data Guard for synchronization, as it relies on its built-in automation features for disaster recovery and high availability. Implement a custom solution using third -party replication software between OCI Frankfurt and OCI Dublin, bypassing Oracle's native technologies for data synchronization. -> Incorrect. While third -party replication software can be used, it may not offer the same level of integration, ease of management, or guarantees for RTO and RPO as Oracle's native solutions like Active Data Guard. During the deployment of an enterprise -grade application on Oracle Cloud Infrastructure (OCI), you decide to leverage OCI Identity and Access Management (IAM) to manage user access and permissions. After configuring your IAM policies, you notice that some users can access more resources than intended, potentially exposing sensitive data. Which of the following misconfigurations is most likely responsible for this unintended access?
unless explicitly configured in such a manner, which is uncommon. The network security group (NSG) rules are too restrictive, mistakenly allowing users to bypass intended IAM policies. -> Incorrect. NSG rules govern network access and do not directly affect IAM policy enforcement. NSG configurations would not result in granting additional access to IAM users. Audit logs are not enabled for all services, preventing the detection of excessive access permissions. -> Incorrect. While enabling audit logs is crucial for monitoring and reviewing access patterns, the lack of audit logs does not directly cause users to have excessive access; it merely hinders the ability to detect such issues. When designing a database solution in Oracle Cloud Infrastructure (OCI) for a high -traffic e -commerce platform that requires both high availability and the ability to handle sudden spikes in read traffic, which database configuration would best meet these requirements?
