including spreading data across Availability Domains, but they primarily rely on built-in redundancy and data protection features rather than spreading user data across Availability Domains. Fault Domains are designed to provide isolation against hardware failures and unexpected software crashes within a single Availability Domain. -> Incorrect. Fault Domains provide isolation within an Availability Domain, protecting against hardware failures and software crashes, thereby contributing to a more fault -tolerant infrastructure. In designing and implementing a hybrid cloud architecture with Oracle Cloud VMware Solution (OCVS), a company aims to extend its on -premises VMware environment to the Oracle Cloud to enhance its disaster recovery capabilities. Which of the following approaches ensures a seamless integration between the on -premises data center and Oracle Cloud, providing efficient disaster recovery while maintaining compliance with data sovereignty regulations?
that might not be in place. Fault domains do not provide isolation from maintenance events. -> Incorrect. Fault domains are specifically designed to provide isolation from hardware failures and maintenance events, but services deployed within them may still require configuration for automatic failover. The Virtual Cloud Network (VCN) does not support cross -fault domain traffic. -> Incorrect. VCNs in OCI are designed to facilitate traffic across fault domains, availability domains, and even regions when configured correctly; thus, this is not a likely cause. Network Security Group (NSG) rules are incorrectly configured, blocking traffic between fault domains. -> Incorrect. Incorrect NSG rules can cause access issues, but this would typically result in consistent access denial rather than intermittent issues, unless the rules are dynamically changing. You are tasked with designing a disaster recovery strategy for your company's critical applications hosted on Oracle Cloud Infrastructure (OCI). Your objective is to ensure minimal downtime and data loss in the event of a region -wide outage. How should you design the disaster recovery plan?
Enhancing security posture by automatically encrypting data at rest and in transit, alongside applying security patches without downtime. -> Incorrect. Security is a strong suit of OCI's Autonomous Database, offering high levels of data protection. A globally recognized media company has recently launched an online streaming platform for movies and TV shows on Oracle Cloud Infrastructure (OCI) to leverage OCI's high availability and scalable infrastructure. The platform's architecture utilizes OCI Compute instances for content delivery, OCI FastConnect for dedicated network connectivity, a Load Balancer to manage viewer traffic, OCI Object Storage for storing media content, and OCI Autonomous Data Warehouse (ADW) for analytics on viewer behavior. During the premiere of a highly anticipated TV series, users experienced intermittent buffering and longer loading times. What could be two possible reasons for these streaming issues?
Your organization has decided to migrate a multi -tiered application to Oracle Cloud Infrastructure (OCI). The application is characterized by heavy compute operations, a relational database backend, and the need for high availability across different geographic regions. To ensure a seamless migration and efficient operation post -migration, which of the following architectures would best support this complex scenario?
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?
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?
