Balancers do not use a 'fail-closed' system for health checks; they reroute traffic away from unhealthy instances. The session persistence configuration on the Load Balancer was not correctly set, leading to session information being unavailable during the outage. -> Incorrect. While session persistence misconfiguration can cause user sessions to drop, it wouldn't bring the entire platform offline in the case of an Availability Domain outage. The web servers in the remaining Availability Domains were not properly scaled to handle the increased load resulting from the outage in one Availability Domain. -> Incorrect. Insufficient scaling might cause performance issues but is unlikely to take the entire platform offline unless the capacity was critically low. You are managing a multi -tier application deployed in Oracle Cloud Infrastructure (OCI), utilizing both public and private subnets within a Virtual Cloud Network (VCN). You've implemented an Internet Gateway (IGW) for outbound internet access from the resources in the public subnet. Recently, you've noticed that the compute instances in the public subnet are unable to access the internet. What should you do first to diagnose and resolve the issue?
security requirement?
Kubernetes nodes. -> Incorrect. While security lists are crucial for network traffic control, this issue specifically involves external traffic reaching the Kubernetes service, not the nodes themselves. As part of your organization's cloud migration strategy to Oracle Cloud Infrastructure (OCI), you have been tasked with implementing an efficient and cost-effective storage solution using OCI Object Storage. To better manage your budget and forecast monthly expenses, which two metrics should you primarily monitor related to Object Storage usage?
Explanation: Deploying the big data platform across multiple regions and Availability Domains is recommended to ensure data locality, reduce latency, and comply with global financial data sovereignty laws. -> Correct. While deploying applications across multiple regions and Availability Domains can enhance disaster recovery and high availability, it may not be necessary or recommended for ensuring data locality and compliance with data sovereignty laws, especially when specific regional data storage requirements are in place. This statement misrepresents the primary considerations for deployment in terms of compliance and latency optimization in a financial context. Leveraging OCI's Big Data Service provides a fully managed Hadoop and Spark environment, which can scale automatically to meet workload demands, ensuring high performance for analytics tasks. -> Incorrect. OCI's Big Data Service provides scalable and fully managed Hadoop and Spark environments, which are crucial for handling large -scale data analytics workloads, ensuring performance and scalability. The use of OCI Data Flow allows for running Apache Spark applications without the need for cluster management, optimizing operational efficiency and scalability for data processing workloads. -> Incorrect. OCI Data Flow offers a serverless Spark service that eliminates the need for cluster management, thereby improving operational efficiency and scalability for big data processing tasks. Integrating OCI Vault with the big data platform ensures encryption keys and secrets are managed securely, enhancing data security and compliance with financial regulations. -> Incorrect. OCI Vault integration with big data platforms ensures secure management of encryption keys and secrets, which is essential for protecting sensitive financial data and meeting compliance requirements. In an enterprise scenario focusing on the consolidation of multiple legacy databases into Oracle Cloud Infrastructure (OCI) for improved scalability and performance, the organization is considering both Autonomous and Base Database services to optimize operations. The legacy systems include a mix of online transaction processing (OLTP) and data warehousing workloads. What are the two most appropriate actions to ensure the success of this migration and operation in OCI, considering the varied workload requirements?
Exadata infrastructure for both ATP and ADW provides the highest performance, isolation, and security for OLTP and data warehousing workloads, respectively. Consolidate all workloads into a single Autonomous Database to simplify management, regardless of their specific processing needs. -> Incorrect. While simplification is a benefit, using a single database type for both OLTP and data warehousing might not offer the specialized performance optimizations that each workload type requires. Deploy all databases on Bare Metal DB Systems, ensuring maximum control over the environment and manual optimization. -> Incorrect. Bare Metal DB Systems provide control but require significant management effort and may not automatically optimize for specific workload types like ATP or ADW can. Use Autonomous JSON Database for all legacy applications, prioritizing ease of use and development over workload -specific optimization. -> Incorrect. Autonomous JSON Database is specialized for JSON document storage and processing, and might not offer the best performance for traditional OLTP or data warehousing workloads. An international retail company is planning to migrate its distributed databases and customer data platforms from various global data centers to Oracle Cloud Infrastructure (OCI) to consolidate its IT infrastructure and take advantage of OCI's global scalability and advanced analytics capabilities. The migration strategy needs to ensure zero data loss, maintain compliance with global data privacy regulations, and minimize impact on customer -facing services. Which two actions are essential for successfully implementing and troubleshooting the database and data migrations to OCI?
safeguards provided by automated tools like OCI's DMS, increasing the risk of data loss and extended downtime. Implement a bulk data transfer over public internet connections to expedite the migration process, prioritizing speed over security to achieve faster consolidation into OCI. -> Incorrect. Bulk data transfers over public internet connections compromise security and reliability, potentially violating data privacy regulations and risking data integrity, especially for sensitive customer data. Bypass the implementation of OCI's dedicated connectivity solutions like FastConnect during migration, relying solely on VPN over the internet for simplicity and cost savings. -> Incorrect. Neglecting dedicated connectivity solutions like FastConnect in favor of VPNs can affect the migration's reliability, performance, and security, especially for large -scale, global data migrations. You are designing a cloud infrastructure for a high -traffic web application that leverages Oracle Cloud Infrastructure Object Storage for serving static content and Oracle Cloud Infrastructure (OCI) Compute instances for dynamic content. The application experiences unpredictable bursts of traffic. Your goal is to ensure high availability and responsiveness without incurring unnecessary costs. Which two options are the least cost -effective or practical methods for handling unexpected spikes in web traffic?
