meeting the healthcare company's requirements for scalability and data security. OCI MySQL Database Service with SSL connection encryption. -> Incorrect. While SSL provides encryption in transit, this option does not guarantee encryption at rest or the high transactional performance required for complex queries specific to patient management systems. OCI NoSQL Database with client -side encryption. -> Incorrect. Client -side encryption offers data security, but OCI NoSQL might not support the complex query requirements of a patient management system, nor does it provide built -in encryption at rest. OCI Virtual Machine DB System with manual encryption setup using third -party tools. -> Incorrect. This option offers flexibility but requires additional management overhead for encryption and may not provide the same level of integrated security features and performance optimization as ATP. When architecting a highly available application infrastructure using Oracle Functions, which of the following statements is true regarding the integration of Oracle Functions with other OCI services for event -driven architecture?
compute instances in multiple OCI regions. What strategy should the firm employ to understand and select the OCI regions that will minimize inter -region latency for its data processing system?
The Infrequent Access Storage tier is designed for data that is not accessed frequently but requires rapid access when needed. -> Correct. The Infrequent Access Storage tier is optimized for data that is accessed less frequently, offering a balance between cost and access time, with lower storage costs than Standard Storage and faster access compared to Archive Storage. The Archive Storage tier requires a minimum storage duration for objects, and retrieving data can take hours. -> Correct. The Archive Storage tier is designed for long -term storage of data that is accessed very infrequently. Objects stored in this tier have a minimum storage duration requirement, and retrieval times can range from hours. The Archive Storage tier offers immediate access to data and is ideal for frequently accessed files. -> Incorrect. The Archive Storage tier is designed for data that is rarely accessed and has the longest retrieval time, making it unsuitable for frequently accessed files. Data stored in the Standard Storage tier incurs higher costs for data retrieval compared to the Archive Storage tier. -> Incorrect. The Standard Storage tier generally incurs lower costs for data storage and retrieval compared to the Archive Storage tier, which has higher retrieval costs. All storage tiers encrypt data at rest, but only the Standard Storage tier provides encryption in transit. -> Incorrect. All storage tiers in OCI Object Storage encrypt data at rest as a standard feature, and encryption in transit is provided across all tiers when accessing data over secure connections (e.g., HTTPS). You are tasked with creating an IAM policy to grant a group of developers access to manage compute instances, but only if the access request comes during official working hours (9 AM to 5 PM, Monday through Friday). Which of the following policy statements best accomplishes this requirement?
specifying day and time conditions in IAM policies. An organization is deploying a multi -tier application on Oracle Cloud Infrastructure (OCI) and requires a DNS solution to efficiently manage name resolution for both public -facing services and internal resources. The application's front end needs to be accessible from the internet, while the backend databases should only be accessible within the cloud network. How should the DNS zones be configured to meet these requirements?
B. Create three separate VCNs for each tier, each with a single subnet. Use an IGW for the web tier VCN, and connect the VCNs with Local Peering Gateways (LPGs). Establish a DRG in each VCN for cross -region connectivity via RPC. C. Implement a single VCN with all subnets set as private. Use a NAT Gateway for the web tier to access the internet, a Service Gateway (SGW) for the application tier to access OCI services, and no gateways for the database tier. Cross -region connectivity is managed with VPN Connect. D. Deploy a single VCN with three subnets: a public subnet for the web tier, a private subnet for the application tier, and another private subnet for the database tier. Use an Internet Gateway (IGW) for the web tier, and set up a Dynamic Routing Gateway (DRG) with Remote Peering Connections (RPC) for cross -region connectivity. Explanation: Configure a single VCN with a public subnet for the web tier and private subnets for the application and database tiers. Utilize an IGW for internet access, a NAT Gateway for the application tier's outbound access, and a DRG with RPC for secure cross -region communication. -> Correct. This setup meets all the specified requirements by correctly using an IGW for the web tier's public internet access, a NAT Gateway for outbound internet access from the application tier without allowing inbound connections, and a DRG with RPC for secure and direct cross -region connectivity. Deploy a single VCN with three subnets: a public subnet for the web tier, a private subnet for the application tier, and another private subnet for the database tier. Use an Internet Gateway (IGW) for the web tier, and set up a Dynamic Routing Gateway (DRG) with Remote Peering Connections (RPC) for cross -region connectivity. -> Incorrect. While this option correctly includes an IGW for the web tier and a DRG with RPC for cross -region connectivity, it simplifies the setup into a single VCN with differentiated subnets for each tier, which is a more streamlined and effective approach. Create three separate VCNs for each tier, each with a single subnet. Use an IGW for the web tier VCN, and connect the VCNs with Local Peering Gateways (LPGs). Establish a DRG in each VCN for cross - region connectivity via RPC. -> Incorrect. This configuration introduces unnecessary complexity by using separate VCNs for each tier, complicating the management and connectivity between tiers, and it doesn't offer any clear advantages for this scenario. Implement a single VCN with all subnets set as private. Use a NAT Gateway for the web tier to access the internet, a Service Gateway (SGW) for the application tier to access OCI services, and no gateways for the database tier. Cross -region connectivity is managed with VPN Connect. -> Incorrect. Using a NAT Gateway for the web tier's internet access is incorrect because the NAT Gateway is designed for outbound internet access from private subnets, not inbound access. Additionally, VPN Connect is generally used for on -premises to OCI connectivity, not for cross -region communication. When implementing and managing connectivity for a Virtual Cloud Network (VCN), which option effectively establishes a secure, private connection between your on-premises network and your VCN?
IP addresses to all components increases complexity and security risks without providing clear benefits, especially for layers that should not be directly exposed to the internet. Which two of the following statements accurately explain the functionality and features of OCI Load Balancing service?
