Implementing a highly available online transaction processing (OLTP) system. -> Incorrect. ATP is well- suited for OLTP systems, providing high availability and disaster recovery features that ensure operational continuity and data integrity. Supporting a complex data warehousing application with real -time data analytics capabilities. -> Incorrect. ATP supports data warehousing applications with advanced analytics features, allowing real- time insights into data with automatic scaling to meet query demands. A healthcare organization, specializing in medical research, is planning to migrate its large datasets and analytical workloads from an on -premises environment to Oracle Cloud Infrastructure (OCI) to leverage advanced analytics and AI capabilities. Their current environment includes Hadoop clusters for big data processing and a variety of custom applications for data analysis, all requiring strict compliance with health data regulations and zero downtime during migration. What is the most effective strategy for migrating their big data environment to OCI, ensuring compliance, and setting up continuous data processing capabilities?
In designing a hybrid and multi -cloud architecture for a client requiring high availability, fault tolerance, and seamless connectivity between Oracle Cloud Infrastructure (OCI) and another major cloud service provider, which of the following options should be implemented? Select two.
interim backups. Explanation: Utilize OCI Database Migration Service for relational databases and manual data transfer for NoSQL databases using scripts. -> Correct. OCI Database Migration Service is optimized for relational database migrations, offering a streamlined and efficient process with minimal downtime. For NoSQL databases, given the potential lack of direct migration services, manual data transfer using custom scripts can be tailored to ensure data integrity, making this approach versatile for handling both database types effectively. Deploy the databases on OCI Virtual Machines using a lift-and-shift approach without specific migration tools. -> Incorrect. While this method can migrate the databases, it might not efficiently address minimal downtime requirements or ensure data integrity, especially for complex multi -tiered applications that require precise synchronization between different database types. Use Oracle Data Pump exclusively for both relational and NoSQL databases. -> Incorrect. Oracle Data Pump is designed primarily for Oracle relational databases. It does not support NoSQL databases directly, making it an inappropriate tool for migrating NoSQL databases while ensuring data integrity and minimal downtime. Implement direct database replication from on-premises to OCI for both database types without interim backups. -> Incorrect. Direct replication without interim backups or using a comprehensive migration service may not adequately handle the intricacies of both relational and NoSQL databases, potentially compromising data integrity and not guaranteeing minimal downtime. A financial services company is planning to deploy a critical application on Oracle Cloud Infrastructure (OCI) that requires strict compliance with financial regulations, demanding high availability (HA) and disaster recovery (DR) capabilities. The application must be able to handle rapid scaling events and ensure data integrity and availability even in the event of a regional outage. Which of the following architectures would best meet these requirements?
Utilize OCI Container Engine for Kubernetes deployed across multiple ADs in a single region, with manual processes for data replication to another region. -> Incorrect. This option provides some level of high availability within a region but relies on manual processes for disaster recovery, which can be slow and error -prone, failing to meet the strict compliance requirements for rapid disaster recovery. Deploy the application on a single OCI Compute instance with Autonomous Database in a single AD, using OCI Block Volume backups for data recovery. -> Incorrect. This approach does not provide the necessary high availability or disaster recovery capabilities, as it relies on a single compute instance and AD, making it vulnerable to both instance and regional failures. You are tasked with securing sensitive data within your company's Oracle Cloud Infrastructure (OCI) environment. The data must be encrypted at rest and in transit to meet compliance requirements. Which approach best achieves this goal?
D. Choose Standard shapes for general -purpose applications such as web and application servers. Explanation: Utilize Dense I/O shapes for high-performance web servers requiring minimal storage. -> Correct. Dense I/O shapes are optimized for workloads that require high I/O throughput and storage capacity, such as databases, not for web servers which typically require less storage but may need more compute or networking performance. Employ GPU shapes for machine learning and scientific computing workloads. -> Incorrect. GPU shapes are ideal for compute -intensive applications like machine learning and scientific computing, offering significant processing power to handle these tasks efficiently. Select High Performance Computing (HPC) shapes for simulations and complex calculations in research. -> Incorrect. HPC shapes are designed to offer the highest compute performance, making them suitable for simulations and complex calculations in various research fields. Choose Standard shapes for general -purpose applications such as web and application servers. -> Incorrect. Standard shapes provide a balance of compute, memory, and networking resources, making them well -suited for a wide range of applications, including web and application servers. You are implementing a disaster recovery strategy for a critical database system in Oracle Cloud Infrastructure (OCI). The primary objective is to minimize data loss and ensure rapid recovery in case of a regional outage. Which of the following strategies would best meet these requirements?
➢ TOTAL QUESTIONS:371 You are tasked with designing a highly available and resilient architecture for a critical application in Oracle Cloud Infrastructure (OCI).
