Leveraging OCI Edge Services -> Incorrect. OCI Edge Services, such as the Content Delivery Network (CDN) and DNS services, can significantly enhance your application's performance and user experience. These services reduce latency by caching content closer to end -users and efficiently routing user requests, which is particularly beneficial for globally distributed applications requiring high scalability and responsiveness. When operating and troubleshooting a complex multi -tier web application deployed on Oracle Cloud Infrastructure (OCI), which of the following practices is most effective in identifying and resolving performance bottlenecks?
boundaries. Utilizing OCI Edge Services to cache content closer to users, thereby reducing latency for frequently accessed data while still maintaining core data in regions that comply with data sovereignty laws. -> Incorrect. OCI Edge Services can significantly reduce latency by caching content close to users, which is effective for static or frequently accessed content without affecting data sovereignty compliance. Design your application using microservices architecture, allowing for different components of your application to be deployed in various regions. -> Incorrect. This not only improves resilience and scalability but also reduces latency by bringing services closer to end-users and ensuring that data is processed within compliant regions. Your company operates a large -scale web application that experiences variable traffic patterns, with significant spikes during holiday seasons. To ensure high availability and scalability, you plan to deploy the application across multiple Availability Domains (ADs) in Oracle Cloud Infrastructure (OCI). Given the need for a highly available database backend with the ability to scale quickly to meet demand, which deployment strategy aligns best with your requirements?
technical requirements for a data-intensive application, which of the following strategies would best optimize performance while ensuring cost efficiency?
Establish an OCI FastConnect connection between each VCN to ensure high -bandwidth, low -latency connectivity for inter -service communication. -> Correct. FastConnect is designed for establishing a dedicated connection between your on -premises network and OCI or between OCI and other cloud providers, not for inter-VCN communication within the same region, making it an inappropriate and costly option for this scenario. Utilize OCI VCN Peering to establish private connectivity between the VCNs across different compartments, ensuring network isolation and secure communications. -> Incorrect. VCN peering is a suitable method for enabling secure, private connectivity between VCNs in the same or different compartments within the same region, maintaining network isolation. Implement OCI Service Gateway in each VCN to route traffic securely between services without traversing the internet, leveraging IAM policies for access control. -> Incorrect. The Service Gateway allows secure access to OCI services within the same region without using the public internet. Deploy an OCI Virtual Cloud Network (VCN) with subnets for each application, using Network Security Groups (NSGs) to control traffic flow between services for isolation. -> Incorrect. Using a single VCN with dedicated subnets for each application and NSGs for traffic control is a valid approach to ensure both connectivity and isolation within a consolidated network structure. When implementing and troubleshooting a database migration to Oracle Cloud Infrastructure (OCI), which tool or service is essential for ensuring a successful and efficient data migration with minimal downtime?
B. The number of API calls to the database C. Storage capacity allocated for database backups D. CPU and memory allocated to the database instance E. Number of database connections Explanation: CPU and memory allocated to the database instance -> Correct. Directly impacts costs as OCI Database service pricing is often based on the compute and memory resources provisioned for the instance. Storage capacity allocated for database backups -> Correct. Storage costs for backups are an important consideration as they contribute to the overall cost, especially for high -availability or disaster recovery configurations. Number of database connections -> Incorrect. While important for performance and scalability, the number of connections does not directly influence the monthly cost of the database service. The number of API calls to the database -> Incorrect. API calls to manage the database might influence operational costs indirectly through management operations but are not a direct cost factor like CPU or storage. Data encryption and security features enabled -> Incorrect. Security features are crucial for compliance and data protection but typically do not have a direct variable cost associated with monthly database service fees. While configuring Oracle Cloud Infrastructure's (OCI) Object Storage for a project, you decide to enforce stricter access policies on a bucket to enhance security. After applying the new policies, users report that they can no longer access the data stored in the bucket. What is the most likely reason for this access issue?
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?
