network in OCI but does not inherently address data processing or residency requirements across multiple regions. Oracle Functions -> Incorrect. Oracle Functions is a serverless platform that allows running code in response to triggers. While it can process data, it doesn't specifically address the requirement for processing data close to its origin across multiple regions. Oracle Cloud Infrastructure FastConnect -> Incorrect. FastConnect provides a high -bandwidth connection between on-premises networks and OCI. It improves network performance but doesn't directly solve for data processing near its origin in multiple regions. In the context of automating infrastructure deployment within Oracle Cloud Infrastructure (OCI), you are tasked with designing a highly available web application architecture. This architecture requires the deployment of compute instances across multiple availability domains to ensure fault tolerance and scalability. To automate this infrastructure, you decide to utilize Infrastructure -as-Code (IaC) practices. Which of the following approaches correctly implements the desired automation while adhering to OCI best practices?
A large financial institution has deployed a critical database system on Oracle Cloud Infrastructure (OCI) that spans across multiple Availability Domains (ADs) for high availability. Recently, they have experienced unexpected downtime during AD maintenance events, despite their high availability setup. The database system uses OCI Block Volume for data storage and employs OCI Data Guard for data replication. As an OCI Architect, you are tasked with proposing a solution to ensure database availability during AD maintenance events without significant changes to the current architecture. Which of the following actions would most effectively enhance the system's resilience to such events?
backups to OCI Object Storage in the same region. B. Implement a cross -region replication using OCI Object Storage to replicate application data and use OCI Traffic Management to automatically redirect traffic to the backup region. C. Use OCI’s built-in disaster recovery tools to automatically replicate all services, including compute, database, and storage, across multiple regions with automated failover. D. Create a secondary environment in a different OCI region and utilize manual failover processes for compute instances and databases during an outage. Explanation: Use OCI’s built -in disaster recovery tools to automatically replicate all services, including compute, database, and storage, across multiple regions with automated failover. -> Correct. Utilizing OCI’s disaster recovery tools for automated replication and failover of all services ensures minimal downtime and maintains application availability even during a regional outage. This approach provides a comprehensive disaster recovery solution. Implement a cross -region replication using OCI Object Storage to replicate application data and use OCI Traffic Management to automatically redirect traffic to the backup region. -> Incorrect. This approach ensures data is replicated across regions, and OCI Traffic Management can direct user traffic to an alternate region in case of an outage, but it does not address compute and database replication comprehensively. Create a secondary environment in a different OCI region and utilize manual failover processes for compute instances and databases during an outage. -> Incorrect. While creating a secondary environment in another region can provide a disaster recovery solution, relying on manual failover processes can lead to significant downtime and is not ideal for mission -critical applications. Deploy all applications on a single, highly available compute instance in one region, with regular backups to OCI Object Storage in the same region. -> Incorrect. Relying on a single compute instance, even with backups, does not provide protection against regional outages and only addresses data backup, not application availability. When implementing a hybrid cloud architecture utilizing the Oracle Cloud VMware Solution (OCVS), which component is essential for enabling seamless migration and operation of VMware workloads between an on -premises data center and OCI?
integration of VMware workloads in a hybrid cloud architecture. OCI Block Volumes -> Incorrect. Although OCI Block Volumes provide high-performance storage for OCI instances, they are not specifically designed to facilitate the migration and operation of VMware workloads between on -premises and cloud environments. When implementing a high -availability solution in Oracle Cloud Infrastructure (OCI) to meet both business and technical requirements, which of the following approaches ensures maximum uptime for a critical application with data residency and sovereignty considerations?
Explanation: OCI Cross -Region Data Guard -> Correct. OCI Cross -Region Data Guard is designed for scenarios requiring high availability and disaster recovery. It automatically replicates data to a secondary region, providing real -time data protection and minimizing downtime and data loss during outages. OCI Object Storage -> Incorrect. OCI Object Storage ensures the durability of stored objects and offers high availability within a region but does not inherently provide disaster recovery across different geographical locations. OCI Functions -> Incorrect. OCI Functions supports event -driven architecture and can contribute to a disaster recovery strategy by automating tasks but does not serve as a primary disaster recovery solution. OCI Identity and Access Management (IAM) -> Incorrect. OCI IAM is crucial for managing access to resources and ensuring security compliance but does not directly contribute to the physical or geographical redundancy needed for effective disaster recovery planning. A rapidly expanding tech startup has recently migrated their high -traffic video streaming service to Oracle Cloud Infrastructure (OCI) to leverage its scalability and robust infrastructure. The service architecture includes OCI Compute instances for video processing, OCI Streaming Service for handling live stream data, a front -end Load Balancer to distribute incoming traffic, and OCI Autonomous Data Warehouse (ADW) for analytics. Following a major global event, the startup decided to stream the event live, resulting in an unprecedented surge in viewership. However, viewers experienced buffering and delays. What could be two possible reasons for these performance issues?
event, causing an uneven distribution of traffic across the backend servers. -> Incorrect. While session persistence can affect load distribution, it is unlikely to be the primary cause of significant performance issues in a high -traffic scenario. The video content was not properly encoded for adaptive bitrate streaming, leading to higher than necessary bandwidth consumption for viewers. -> Incorrect. While improper encoding can affect viewer experience, it does not directly impact the backend infrastructure's ability to handle traffic. When planning and designing solutions in Oracle Cloud Infrastructure (OCI), which of the following is the most effective strategy for ensuring high availability and fault tolerance for a multi -tier web application?
