Migrate the database layer to OCI Autonomous Database to leverage its automatic scaling, backup, and patching features, reducing management overhead. -> Correct. Utilizing OCI Autonomous Database for the database layer can significantly reduce management overhead and costs by automating scaling, backups, and patching, ensuring high availability and performance for the e -commerce application. Consolidate the application into a monolithic architecture and deploy on a single large OCI Compute instance to simplify operations. -> Incorrect. While consolidation into a monolithic architecture might simplify operations in some cases, it contradicts the objectives of scalability and rapid deployment, making it harder to scale specific components or deploy updates efficiently. Implement the entire application stack as a series of interconnected serverless functions using OCI Functions to minimize costs and operational overhead. -> Incorrect. Although serverless architectures like OCI Functions can reduce costs and operational overhead for certain use cases, completely refactoring an N -tier e -commerce application into serverless might introduce complexity in managing state and long -running processes, which are better handled by other architectures. Use OCI FastConnect to establish a dedicated network connection between the on-premises data center and OCI, ensuring low -latency access to the application. -> Incorrect. OCI FastConnect provides a dedicated network connection that may benefit hybrid architectures or data migration scenarios but does not directly contribute to the scalability, deployment, or cost -efficiency objectives of refactoring the application. A cloud engineer is troubleshooting a connectivity issue between an Oracle Cloud Infrastructure (OCI) compute instance and a database hosted on OCI. The compute instance is unable to establish a connection to the database, resulting in timeout errors. Which option is not a plausible reason for this connectivity issue?
from reaching the database. -> Incorrect. Misconfiguration of the DRG could impact traffic flow between different networks or services in OCI, making this a plausible reason for connectivity issues. A global e -commerce company is planning to migrate its existing online platform to Oracle Cloud Infrastructure (OCI) to improve scalability, performance, and global reach. The platform experiences unpredictable spikes in traffic, particularly during holiday seasons and flash sales. It also handles sensitive customer data, requiring stringent security and compliance measures, including GDPR. The architecture needs to support auto -scaling, low -latency access to databases, and must ensure data residency requirements are met for customers in Europe. Which of the following architectures would best satisfy these business and technical requirements?
Compute instances based on predicted traffic patterns. -> Incorrect. While innovative, this approach does not offer the necessary scalability or efficiency for handling unpredictable traffic spikes in an e - commerce environment. It also complicates data management and does not directly address the specific requirement for low -latency database access or GDPR compliance for data residency. Your organization plans to migrate several legacy applications to Oracle Cloud Infrastructure (OCI) to take advantage of cloud scalability and performance. One critical application relies on a legacy database that uses a non -standard file format for data storage. Your migration strategy needs to ensure minimal downtime and rapid data access once the migration is complete. The legacy database size is approximately 20 TB. Which migration strategy is the most cost -effective while ensuring data availability and integrity?
B. Configure OCI Identity and Access Management (IAM) and the secondary cloud provider’s IAM with federated identities to manage cross -cloud access control. C. Deploy a multi -cloud management platform that offers unified monitoring, management, and cost tracking for resources across both OCI and the secondary cloud provider. D. Use only OCI’s native tools for monitoring and management purposes, to avoid the overhead of learning additional tools for the secondary cloud provider. E. Leverage public internet for inter-cloud communication to utilize widely available resources and reduce operational complexity. Explanation: Configure OCI Identity and Access Management (IAM) and the secondary cloud provider’s IAM with federated identities to manage cross -cloud access control. -> Correct. Federated IAM ensures seamless and secure identity management across cloud environments, facilitating centralized control and compliance. Deploy a multi -cloud management platform that offers unified monitoring, management, and cost tracking for resources across both OCI and the secondary cloud provider. -> Correct. A multi -cloud management platform simplifies operations, enhances visibility, and aids in controlling costs across the cloud environments. Leverage public internet for inter-cloud communication to utilize widely available resources and reduce operational complexity. -> Incorrect. Using the public internet exposes critical data to higher security risks and potential performance issues compared to private connectivity options. Use only OCI’s native tools for monitoring and management purposes, to avoid the overhead of learning additional tools for the secondary cloud provider. -> Incorrect. Relying solely on OCI’s tools limits visibility and control over resources in the secondary cloud, undermining the efficiency of hybrid and multi -cloud operations. Prioritize the deployment of stateful applications on OCI only, to simplify disaster recovery and data residency compliance efforts. -> Incorrect. This approach restricts the application’s scalability and availability benefits of a multi -cloud strategy and may not adequately address compliance requirements. You are consulting for an enterprise planning to deploy a critical application on the Oracle Cloud Infrastructure (OCI) that requires consistent performance and minimal latency. The application will be hosted on a cluster of compute instances within the same region but across multiple availability domains. To ensure high availability, you need to implement a load balancer. However, after setup, you notice that the application is experiencing uneven load distribution and performance issues. What could be the reason?
are designed to distribute traffic across instances in multiple availability domains, so this configuration would not be a limitation. Load balancers in OCI do not support cross -availability domain traffic management. -> Incorrect. This statement is incorrect because OCI load balancers are specifically designed to manage traffic across multiple availability domains within the same region. Network Security Group (NSG) rules are blocking traffic to some instances. -> Incorrect. While NSG rules can block traffic to instances, they would not cause uneven load distribution unless they are inconsistently applied across instances targeted by the load balancer. You are tasked with designing a high availability architecture for a web application in Oracle Cloud Infrastructure (OCI) that leverages the Autonomous Database (ADB) for data storage. The goal is to ensure maximum uptime and resilience to region -wide failures. Choose the two actions that are not required to ensure high availability and resilience for the web application and database.
report health data in real-time. The system requires high availability, scalability to handle variable loads, and strict compliance with healthcare data privacy regulations. The startup wants to leverage Oracle Cloud Infrastructure (OCI) for its deployment, ensuring a seamless experience for both patients and healthcare providers. Which two architectural decisions should the architect recommend to optimally meet these requirements with a focus on N -tier applications, microservices, and serverless architectures?
