D. Deploy the application using Oracle Kubernetes Engine (OKE) to automate deployment, scaling, and operations of containerized applications, enhancing the system's scalability and availability. Explanation: Deploy the application using Oracle Kubernetes Engine (OKE) to automate deployment, scaling, and operations of containerized applications, enhancing the system's scalability and availability. -> Correct. Utilizing OKE for deploying the supply chain management system allows for automated scaling and management of containerized applications, ensuring the system can handle varying loads while maintaining high availability. Use OCI Identity and Access Management (IAM) to control access to the supply chain management system, assigning roles and permissions based on job function to ensure secure access to application resources. -> Correct. Implementing OCI IAM provides a secure access management system, allowing the company to control who can access the supply chain management system, what resources they have access to, and how they can interact with those resources, thus ensuring data security and compliance. Configure a Virtual Cloud Network (VCN) with public subnets for all components of the system to simplify network access and reduce operational complexity. -> Incorrect. Configuring all components in public subnets exposes the system to potential security threats. A more secure approach would involve using a combination of public and private subnets, with critical components placed in private subnets and accessed through secure methods. Implement the system entirely on OCI Functions to maximize operational efficiency and cost - effectiveness by leveraging a serverless architecture for all components. -> Incorrect. Although OCI Functions can improve operational efficiency and reduce costs for specific tasks, relying entirely on a serverless architecture for a complex system like supply chain management might not provide the necessary control, performance, and integration capabilities needed for real-time tracking and analytics. As an OCI Architect, you are tasked with enhancing the security of your cloud environment. Which two statements are false regarding the implementation of security practices in Oracle Cloud Infrastructure (OCI)?
services is encrypted and secured. -> Correct. Customer Secret Keys in OCI are used for signing API requests, not for encrypting data at rest. OCI uses encryption keys managed through the OCI Vault service for encrypting data at rest. OCI Identity and Access Management (IAM) allows for the creation of policies that grant users permissions based on the principle of least privilege. -> Incorrect. This statement is true, highlighting OCI IAM's capability to enforce the principle of least privilege by granting specific permissions to users, which is a best practice in cloud security. The OCI Vault service enables the management of encryption keys and secrets, such as API keys and credentials, which can be used to encrypt data at rest and in transit. -> Incorrect. This is a true statement, as the OCI Vault service indeed provides key management and secret storage capabilities, which are crucial for securing encryption keys and sensitive information like API keys. The OCI Vault service enables the management of encryption keys and secrets, such as API keys and credentials, which can be used to encrypt data at rest and in transit. -> Incorrect. This is a true statement, as the OCI Vault service indeed provides key management and secret storage capabilities, which are crucial for securing encryption keys and sensitive information like API keys. In designing a multi -tier web application for a financial services company on Oracle Cloud Infrastructure (OCI), you are tasked with ensuring that the application's database layer remains isolated from the internet, while still allowing the application tier to communicate with it securely. Which OCI feature would best achieve this requirement?
microservices and traditional N -tier components, ignoring serverless. B. Using OCI Container Engine for Kubernetes (OKE) to host all microservices across multiple Availability Domains, with OCI Functions handling occasional background tasks. C. Hosting the entire application on OCI Functions to maximize cost efficiency, regardless of the complexity of inter -service communication. D. Deploying all tiers of the application on dedicated OCI Compute instances within a single Availability Domain for performance consistency. Explanation: Using OCI Container Engine for Kubernetes (OKE) to host all microservices across multiple Availability Domains, with OCI Functions handling occasional background tasks. -> Correct. This pattern effectively leverages OKE for microservices, ensuring scalability and high availability by distributing services across multiple Availability Domains. OCI Functions complement this by providing a cost -efficient solution for executing occasional background tasks, thereby combining flexibility, scalability, and cost efficiency. Hosting the entire application on OCI Functions to maximize cost efficiency, regardless of the complexity of inter -service communication. -> Incorrect. While OCI Functions offer cost efficiency, relying solely on serverless for a complex N-tier application with microservices could lead to challenges in managing state and the complexity of inter -service communication. Deploying all tiers of the application on dedicated OCI Compute instances within a single Availability Domain for performance consistency. -> Incorrect. Using dedicated Compute instances may provide performance consistency but lacks the scalability and cost efficiency of serverless and does not utilize the flexibility of microservices architecture. Leveraging a single large OCI Kubernetes cluster spread across multiple regions for both microservices and traditional N -tier components, ignoring serverless. -> Incorrect. A single Kubernetes cluster across multiple regions could introduce complexity and potential latency issues, and ignoring serverless options misses opportunities for cost optimization in scenarios suited to event -driven, ephemeral tasks. A retail company seeks to enhance its customer experience by leveraging Oracle Cloud Infrastructure (OCI) for deploying a new analytics platform. The company aims to utilize real -time data processing and analytics to gain insights into customer behavior. The project manager has approached you to design the migration strategy from their current data warehouse to OCI. The information provided includes the size of the data warehouse, peak data ingestion rates, expected query performance improvements, and compliance requirements. Which two pieces of additional information are crucial to recommend an optimal migration and deployment strategy?
optimized for query performance. Current hardware specifications of the data warehouse servers. -> Incorrect. While helpful, knowing the hardware specifics is less critical when moving to a cloud environment where the focus shifts to service capabilities and configurations. Number of concurrent users during peak hours. -> Incorrect. While important for sizing and performance tuning, this does not significantly impact the initial migration strategy decision. Version of the data warehouse software currently in use. -> Incorrect. The specific version is less relevant as the migration to OCI might involve moving to a different data platform or service that does not depend on the on -premises version compatibility. A financial services company needs to ensure high availability for its critical Oracle databases that handle transaction processing. The databases are currently hosted in an on -premises data center. The company aims to implement a disaster recovery (DR) solution in Oracle Cloud Infrastructure (OCI) that allows for an RPO (Recovery Point Objective) of 15 minutes and an RTO (Recovery Time Objective) of 1 hour. The DR solution must also be cost -effective while ensuring data integrity and quick failover capabilities. Which of the following is the most efficient and cost -effective way to achieve these DR objectives?
for this situation?
A large healthcare organization is planning to migrate its legacy on-premises databases to Oracle Cloud Infrastructure (OCI) to improve scalability, performance, and availability while ensuring compliance with healthcare regulations such as HIPAA. The organization has a mix of relational and NoSQL databases that are critical for its daily operations. As an OCI Architect, you are tasked with designing a solution that meets these requirements. Which of the following database solutions on OCI would best fit the organization's needs?
