Listener 1 • Virtual hostname: none • Default backend set: J • Path route set: PathRouteSet2 Listener 2 • Virtual hostname: secure.com • Default backend set: K • Path route set: PathRouteSet2 Listener 3 • Virtual hostname: public.com • Default backend set: L • Path route set: PathRouteSet2 Path Route Set • Path route set name: PathRouteSet2 • Exact match on path string /private/ routes to backend set K. • Prefix match on path string /open/ routes to backend set L. Given this configuration, determine the correct routing for the URLs below: U1: http://secure.com/private/account U2: http://public.com/open/data Which of the following statements is true?
the users. -> Incorrect. This is a primary use case for CDN, as it helps in delivering content faster to end users by caching content at geographically distributed edge locations. Offloading traffic from the origin server to handle high demand and improve application scalability. -> Incorrect. Using CDN to offload traffic from the origin server is a recommended practice. It helps in managing large volumes of traffic and improves the scalability of the application by distributing requests across the CDN. Distributing software updates and patches efficiently to users around the globe. -> Incorrect. CDNs are ideal for distributing software updates and patches because they can efficiently handle large files and distribute them quickly to users worldwide, reducing the load on the origin server. As an Oracle Cloud Infrastructure Architect, you are designing a solution for a financial services application that requires a highly available and scalable database setup within OCI. The application demands automatic scaling, self-repair capabilities, and strong consistency across database instances. Given these requirements, which database solution would you recommend implementing to meet the application's needs while optimizing for performance and manageability?
Cloud Infrastructure (OCI), which two considerations are crucial to optimize costs without compromising performance?
scalability, high availability, and DR, ensuring the platform can handle spikes in demand and maintain operations during regional outages. Deploy the streaming platform in a single OCI region, utilizing multiple Availability Domains (ADs) and horizontal scaling with OCI Compute instances for the application layer. -> Incorrect. While this approach provides high availability within a single region and allows for horizontal scaling, it does not address disaster recovery requirements for regional outages. Implement the platform using OCI Functions for serverless computing across multiple regions, with an OCI Streaming service for data handling and cross -region replication for DR. -> Incorrect. Although using OCI Functions and OCI Streaming services supports scalability and can handle variable loads, relying solely on these services without a detailed cross -region replication strategy for all components might not fully meet the DR requirements. Deploy the application on OCI Compute instances with manual scaling in a single region, using OCI Block Volumes for storage and manual snapshots for data backup and recovery. -> Incorrect. Manual scaling and snapshot -based data recovery are not suitable for a platform requiring rapid response to variable load and robust disaster recovery capabilities. This approach lacks automation and does not provide the necessary resilience against regional failures. You are an architect tasked with designing a highly available and resilient application deployment on Oracle Cloud Infrastructure (OCI) for a global e-commerce platform. The application must support auto- scaling to handle varying loads, maintain high availability across multiple regions, and ensure data consistency with minimal latency for users worldwide. Which of the following strategies should you implement to meet these business and technical requirements? Select two.
and may introduce latency issues for users in distant locations. Implement a single instance VM in each desired region without auto -scaling, relying on OCI's built -in redundancy for high availability. -> Incorrect. Single instance VMs do not provide the necessary scalability or fault tolerance for a high-traffic e-commerce platform. Without auto-scaling, the application cannot adapt to changing loads, risking performance issues or downtime. Configure a DNS -based global load balancer with health checks outside of OCI, and use a single -region deployment for the application. -> Incorrect. While a DNS -based global load balancer can distribute traffic, using a single -region deployment fails to leverage OCI's global infrastructure for high availability, and may introduce high latency for users far from the chosen region. An innovative software development company specializing in AI applications has recently deployed a complex machine learning model on Oracle Cloud Infrastructure (OCI) to offer as a service to its clients. The deployment architecture includes OCI Compute instances for model execution, OCI Object Storage for storing training datasets and model artifacts, a Load Balancer to manage API requests to the model, and OCI Autonomous Database for storing application data. To showcase the capabilities of their model, the company hosted a live demo for potential clients. During the demo, users experienced slow response times when querying the model. What could be two possible reasons for this 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?
