system. They've noticed fluctuations in demand that affect system performance and wish to optimize costs without sacrificing user experience. What OCI feature would you recommend they use to automatically adjust their compute resources in response to workload demands?
transported to another region is a viable, albeit manual, strategy for disaster recovery. Use OCI GoldenGate for real -time data replication across databases in different regions. -> Incorrect. OCI GoldenGate allows for real-time data replication across databases, even in different regions, making it suitable for high availability and disaster recovery scenarios. As a cloud architect, you are designing a data backup solution on Oracle Cloud Infrastructure (OCI) for a client. Your client's data backup policy requires encryption of backups both in transit and at rest. Which of the following steps is not necessary when implementing this policy using OCI Object Storage?
regions. -> Correct. Oracle Autonomous Database on shared infrastructure with cross -region Data Guard enables high availability, disaster recovery, and strict consistency, meeting the application's requirements. Deploy Oracle Database on a VM DB System in a single availability domain. -> Incorrect. This setup does not provide high availability or disaster recovery across multiple regions, as it is limited to a single availability domain. Configure MySQL Database Service with manual replication across multiple availability domains in the same region. -> Incorrect. While this provides some level of high availability within a single region, it lacks automatic failover and does not cover disaster recovery across multiple regions. Set up Oracle NoSQL Database with replication across multiple availability domains. -> Incorrect. Oracle NoSQL Database is not a relational database, and while it can provide high availability within a region, it does not meet the strict consistency requirements of the application. In planning the deployment of a critical financial analytics application in Oracle Cloud Infrastructure (OCI), a FinTech company needs to ensure maximum security, compliance with financial regulations, efficient data processing, and scalability. The application requires real -time data analysis, secure data storage, and the ability to scale resources dynamically based on the load. Additionally, the solution must incorporate disaster recovery strategies and comply with global financial regulatory standards. Which of the following architectures would best meet these requirements?
manual backups. -> Incorrect. While this setup emphasizes security with private subnets and serverless compute for scalability, it falls short in providing real -time disaster recovery and does not leverage the best storage solution for analytics and compliance needs. Deploy the application in a single OCI region using dedicated compute instances for each application component, manual snapshot backups for disaster recovery, and third-party tools for data encryption and compliance monitoring. -> Incorrect. Relying on dedicated compute instances and manual processes for backups and scaling significantly reduces the solution's ability to meet dynamic scalability needs, real - time disaster recovery, and may not ensure full compliance with financial regulations. ABC Enterprises is planning to enhance the security posture of their cloud -native applications deployed on Oracle Cloud Infrastructure (OCI). They aim to implement a solution that not only secures their applications from internet threats but also provides detailed insights and control over the traffic. Which of the following options would best fulfill their requirements?
D. Use OCI Object Storage to copy backups to a bucket in the same region with versioning enabled. Explanation: Enable OCI Object Storage Replication to automatically replicate data to another bucket in a different region. -> Correct. OCI Object Storage Replication allows for the automatic replication of data to a bucket in a different region, meeting the geographic separation requirement for disaster recovery and ensuring data availability in case of a regional disaster. Use OCI Object Storage to copy backups to a bucket in the same region with versioning enabled. -> Incorrect. This approach adds a layer of protection against accidental deletion or overwriting of data with versioning but does not meet the requirement for geographic separation for disaster recovery purposes. Manually transfer backup files to an external physical hard drive and store it in a different geographic location. -> Incorrect. While storing data on a physical hard drive in a different location meets the geographic separation requirement, this manual process is not efficient, potentially insecure, and does not leverage OCI's cloud capabilities for disaster recovery. Configure backups to another cloud provider in a different geographic location without encryption. -> Incorrect. Backing up to another cloud provider may meet the geographic separation requirement but transferring sensitive patient records without encryption could violate security and privacy regulations, risking patient confidentiality. Your organization is deploying a distributed application across multiple regions in Oracle Cloud Infrastructure (OCI) to improve global accessibility and fault tolerance. The application consists of microservices that communicate frequently with each other. Given the critical nature of this application, minimizing latency and ensuring secure communication between microservices is paramount. You are tasked with designing the network architecture to meet these requirements. Which two options are the least efficient or practical approaches for ensuring low latency and secure communication between microservices across regions?
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?
