Migration Service supports minimal downtime migrations, making it ideal for high-transactional databases. Implement the database on OCI Autonomous Database to automatically scale and manage performance. -> Correct. OCI Autonomous Database offers automatic scaling and self-managing capabilities, suitable for high -transactional workloads. Deploy the database on OCI Object Storage for improved scalability. -> Incorrect. OCI Object Storage is not suitable for high -transactional databases due to its design for unstructured data storage. Configure the database in a VM on OCI to manually manage scalability and performance. -> Incorrect. While this offers control over the environment, it requires significant manual effort to manage scalability and performance, which may not meet the business requirement for minimal downtime. Set up a Disaster Recovery (DR) site on OCI with manual replication. -> Incorrect. Manual replication for a high -transactional database could lead to significant downtime and data loss, not aligning with the company's requirements. You have set up a cloud infrastructure in Oracle Cloud Infrastructure (OCI) that includes a public -facing web application hosted on a Compute instance within a public subnet. You need to ensure the web application can securely access OCI Object Storage to retrieve static assets without exposing the Object Storage to the public internet. Which two steps should you take to establish this secure connectivity?
Explanation: Implement a centralized logging and monitoring solution that aggregates logs and metrics from both OCI and the secondary cloud provider, enabling unified observability across the multi -cloud environment. -> Correct. A centralized logging and monitoring framework is essential for gaining insights into application performance and health across all cloud environments, facilitating prompt issue resolution and informed decision -making. Utilize Oracle FastConnect and the equivalent direct connection service of the secondary cloud provider to establish a dedicated, private connection between the two clouds for secure and high -performance inter-cloud communication. -> Correct. Direct connections like Oracle FastConnect and its equivalents reduce latency, increase bandwidth, and enhance security compared to internet -based connections, supporting efficient multi -cloud operations. Deploy the application’s database exclusively in OCI using Autonomous Database to leverage OCI’s superior performance and scalability, while hosting the application front end on the secondary cloud provider. -> Incorrect. This approach could introduce unnecessary latency between the application front end and the database, potentially degrading performance. It overlooks the benefits of proximity and network optimization within a single cloud provider. Rely exclusively on public internet connections for data transfer and inter-cloud communication to avoid the costs and complexity of setting up dedicated connectivity solutions. -> Incorrect. Using the public internet can expose critical data transfers to higher latency, reduced security, and less reliable connectivity, which could negatively impact the application’s performance and user experience. Mirror all data synchronously in real -time between OCI and the secondary cloud provider to ensure immediate failover and zero data loss in the event of a disaster. -> Incorrect. While synchronous mirroring offers high availability, it can be very costly and may introduce significant latency, especially across cloud regions or providers, potentially affecting application performance. In implementing a solution on Oracle Cloud Infrastructure (OCI) to meet both stringent security requirements and global accessibility for a financial services application, which of the following approaches would most effectively align with these business and technical requirements?
accessibility through Internet Gateway with standard network security group (NSG) rules for security. -> Incorrect. While deploying in a public subnet may enhance global accessibility, relying solely on standard NSG rules without additional security measures may not meet the stringent security requirements of a financial services application. Utilizing OCI Identity and Access Management (IAM) to strictly control user access, while hosting the application across multiple regions using OCI's global DNS service for accessibility. -> Incorrect. OCI IAM is critical for controlling access but does not address all aspects of application security or ensure global accessibility through architectural decisions alone, such as the need for multi -region deployment and traffic management solutions. Relying on encryption at rest and in transit within a single OCI region, disregarding multi -region deployment for the sake of simplifying security management. -> Incorrect. While encryption is a fundamental security measure, focusing only on encryption within a single region overlooks the benefits of multi -region deployment for disaster recovery and global accessibility, which are crucial for meeting the broader set of business and technical requirements for a financial services application. You are responsible for optimizing the performance of an enterprise -grade web application deployed on Oracle Cloud Infrastructure (OCI), utilizing Oracle Functions for serverless computing and Oracle Cloud Infrastructure Object Storage for data persistence. During periods of high demand, you observe latency issues affecting user experience. The web application's architecture is designed to scale horizontally, but improvements are needed to handle peak load efficiently. Which two options are expensive or impractical ways to improve the application's performance during peak times?
decreasing the number of fetch or compute operations. This is generally a cost-effective method to improve performance. Utilize autoscaling for Oracle Functions to automatically adjust resources based on the trigger metrics defined, ensuring optimal resource usage throughout. -> Incorrect. Autoscaling is a cost -efficient and practical way to handle variable loads, as it adjusts resources automatically to match demand, improving performance without unnecessarily increasing costs. Optimize the application code and data retrieval queries to ensure that they are efficiently written and make minimal calls to Object Storage, relying more on in -memory processing where possible. -> Incorrect. Optimizing application code and queries is a practical and cost -effective way to improve performance, ensuring that operations are executed more efficiently without additional costs. A global logistics company is evaluating the transition of their inventory management system from a legacy on-premises setup to Oracle Cloud Infrastructure (OCI) to improve scalability and real-time data analysis capabilities. They have provided specifics about their system, including transaction volumes, database size, reporting requirements, and current system performance metrics. Which two pieces of additional information are essential for you to devise a targeted migration strategy?
D. Implement Oracle Cloud Infrastructure FastConnect and OCI Identity and Access Management (IAM) to create dedicated, high-bandwidth connections and manage cross -regional access controls. Explanation: Implement Oracle Cloud Infrastructure FastConnect and OCI Identity and Access Management (IAM) to create dedicated, high -bandwidth connections and manage cross -regional access controls. -> Correct. FastConnect provides a secure, high -bandwidth connection ideal for hybrid cloud architectures, while OCI IAM enables fine -grained access control and compliance across multiple regions. Use Oracle Cloud Infrastructure (OCI) public IP addresses for interconnecting the on -premises data center with OCVS instances across multiple regions. -> Incorrect. Public IP addresses expose services to the internet, increasing security risks and potentially violating compliance requirements. Deploy a single, centralized OCVS instance in one region to serve all global operations, using VPN for connectivity from all other regions. -> Incorrect. This approach introduces latency for remote regions and fails to leverage regional data centers for localized compliance and performance. Configure Oracle Cloud Infrastructure Object Storage as the sole shared storage solution between on- premises environments and OCVS across all regions. -> Incorrect. Relying solely on Object Storage ignores the performance and latency requirements of some applications and does not fully support the features and capabilities of VMware -based workloads. While optimizing your company's cloud infrastructure in Oracle Cloud Infrastructure (OCI), you are tasked with evaluating the compute resources to ensure efficient cost management. Which two factors should you primarily monitor to accurately forecast your monthly costs for using OCI Compute instances?
