application in phases, which can include databases, application servers, and other components. It provides a way to manage dependencies and minimize downtime. However, it requires careful planning and might not be the fastest option. Replicating the entire on-premises environment onto a single large Oracle Cloud Infrastructure Compute instance -> Incorrect. Replicating the entire environment onto a single compute instance does not leverage the scalability and flexibility of cloud architecture. It could lead to performance bottlenecks and does not consider the complexity of managing interdependent services. You are responsible for ensuring high availability and disaster recovery for a critical application deployed on Oracle Cloud Infrastructure (OCI). The application must be capable of surviving regional outages with minimal downtime. Which deployment strategy should you employ?
facilitating data backup and archival. B. OCI Cross -Region Data Guard ensures real-time data replication and automatic failover between primary and standby databases across regions, minimizing downtime and data loss. C. OCI offers distributed denial of service (DDoS) protection to safeguard applications against downtime and ensure availability. D. OCI FastConnect provides dedicated network connectivity, enhancing the firm's application performance and reducing the risk of internet -based attacks. Explanation: OCI Cross -Region Data Guard ensures real -time data replication and automatic failover between primary and standby databases across regions, minimizing downtime and data loss. -> Correct. Cross - Region Data Guard is designed to meet stringent disaster recovery requirements by providing real-time data replication and failover capabilities across regions. OCI offers distributed denial of service (DDoS) protection to safeguard applications against downtime and ensure availability. -> Incorrect. While DDoS protection is crucial for safeguarding against certain cyber threats, it does not directly address the firm's needs for disaster recovery and data replication. OCI FastConnect provides dedicated network connectivity, enhancing the firm's application performance and reducing the risk of internet -based attacks. -> Incorrect. FastConnect improves connectivity and performance but does not provide a disaster recovery solution. OCI Storage Gateway enables the firm to integrate on -premises applications with cloud storage, facilitating data backup and archival. -> Incorrect. Storage Gateway facilitates cloud storage integration but is not primarily focused on real -time disaster recovery and failover solutions. A large enterprise plans to migrate several critical workloads to Oracle Cloud Infrastructure (OCI) to benefit from cloud scalability and innovation while ensuring minimal disruption to its operations. The migration includes various types of workloads, such as databases, applications, and storage systems. What are two key steps the enterprise should take using Oracle Cloud Migrations to ensure a successful migration strategy that minimizes downtime and maintains data integrity?
synchronization between on -premises databases and OCI, ensuring zero data loss during the migration. -> Correct. Automated data replication ensures continuous synchronization between source and target environments, minimizing downtime and ensuring data integrity throughout the migration process. Opt for an immediate, all -in-one migration approach for all workloads to reduce the overall migration timeline, leveraging Oracle Cloud Migrations' bulk transfer capabilities. -> Incorrect. An immediate, bulk migration of all workloads increases the risk of downtime and potential data integrity issues. A phased approach, considering dependencies and criticality, is more effective. Rely solely on internet -based VPN for the migration process to avoid the costs associated with dedicated connectivity solutions like Oracle FastConnect. -> Incorrect. While cost-saving, using only internet -based VPN may not provide the necessary reliability, security, or bandwidth for migrating critical workloads, potentially leading to extended downtime and security vulnerabilities. Skip the pilot migration phase and directly proceed with full-scale migration to expedite the transition to OCI, based on Oracle Cloud Migrations' planning recommendations. -> Incorrect. Skipping a pilot migration phase forgoes the opportunity to identify potential issues in a controlled environment, increasing the risk of unexpected challenges during the full -scale migration. A software development firm is planning to move its development and testing environments to Oracle Cloud Infrastructure (OCI) to benefit from cloud scalability and improve collaboration among its global teams. The firm has provided information about the current setup, including the number of environments, average build times, and specific toolchain components used in the development process. Which two pieces of additional information are crucial for you to devise a comprehensive migration strategy?
A fintech company is deploying a new blockchain -based payment processing application on Oracle Cloud Infrastructure (OCI) that requires extremely high availability, rapid scalability in response to fluctuating transaction volumes, and robust disaster recovery capabilities to comply with financial industry standards. Which two architectural decisions should the architect include in the design to meet these critical 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.
