Instances in private subnets can be accessed directly from the internet if they have a public IP address. -> Incorrect. Instances in private subnets are not designed to be directly accessible from the internet, even with a public IP address; such accessibility is a characteristic of public subnets. Public subnets require a Dynamic Routing Gateway (DRG) for internet connectivity, while private subnets use an Internet Gateway. -> Incorrect. This statement is reversed; public subnets use an Internet Gateway for internet access, while a DRG is used for connecting a VCN to external networks, such as an on-premises data center, not for direct internet connectivity. When configuring a site-to-site VPN for secure connectivity between your on-premises network and your OCI virtual cloud network (VCN), which two of the following options are true?
In the context of implementing and managing File Storage in Oracle Cloud Infrastructure (OCI), which two of the following statements are correct?
Explanation: Create a Private DNS zone for internal domain names and a Public DNS zone for external domain names. -> Correct. Correct because this setup ensures that internal domain names are resolved within the cloud network, maintaining privacy and security, while external domain names are resolved publicly on the internet. Create a Public DNS zone for internal domain names and a Private DNS zone for external domain names. -> Incorrect. Typically, internal domain names should be managed in a Private DNS zone to keep internal network information secure, while external domain names are managed in a Public DNS zone to be accessible from the internet. Create a Private DNS zone for both internal and external domain names. -> Incorrect. External domain names need to be resolved publicly, which requires a Public DNS zone to ensure they are accessible from the internet. Create a Public DNS zone for both internal and external domain names. -> Incorrect. Exposing internal domain names in a Public DNS zone can lead to security risks by making internal network structure visible to the internet. When deploying and managing Block Storage volumes for high-performance applications, which of the following options is most critical to ensure optimal performance and durability?
Configuring Storage Gateway -> Incorrect. Storage Gateway facilitates cloud integration for on-premises applications by connecting them to OCI Object Storage. It does not directly affect the performance or management of Block Storage volumes. A financial analytics firm is deploying a data -intensive application on Oracle Cloud Infrastructure (OCI) that requires high I/O throughput and low latency for its block storage volumes to process real -time financial transactions efficiently. The firm needs to select the appropriate Block Volume performance tier to meet these stringent requirements. Which Block Volume performance tier should the firm select to ensure optimal performance for its data -intensive application?
Implement Oracle Database In-Memory on the existing instance to accelerate analytics. -> Correct. This solution directly targets the need to improve performance during read -heavy operations by keeping frequently accessed data in memory, which is especially beneficial for analytics and reporting queries without the need for permanent resource scaling. Increase the CPU count of the database instance permanently. -> Incorrect. While this could improve performance, it does not directly address the sporadic nature of read -heavy workloads and results in higher costs without being demand -responsive. Migrate the database to a Dense I/O instance shape for improved disk performance. -> Incorrect. This option could potentially improve overall performance but may not be the most cost-efficient method for addressing intermittent demand spikes in read operations. Enable Autoscaling on the database instance to dynamically adjust resources based on workload. -> Incorrect. Autoscaling helps manage CPU and memory resources but may not be as effective for read- heavy workloads that benefit more from faster data retrieval methods like in -memory storage. When designing a highly available application infrastructure, which Load Balancer policy should you choose to ensure that incoming requests are distributed to backend servers based on the origin of the request to reduce latency?
Explanation of Incorrect Options: Option A: Creating a new Object Storage bucket in another region and configuring a recycle policy to move data every 5 days does not provide real-time data availability or the fault tolerance required for a financial application. Recycle policies are intended for managing the lifecycle of data, not for high availability or disaster recovery. Option C: While lifecycle policies are useful for moving less frequently accessed data to a more cost - effective storage tier (e.g., from Standard to Archive), they do not address cross -region redundancy or real-time availability, which are critical for this use case. Option D: Copying an Object Storage bucket to a block volume is not a recommended practice for ensuring data durability and fault tolerance. Block volumes are used for persistent storage attached to compute instances, and copying object storage data to block volumes does not achieve the same level of redundancy and cross -region availability as replication policies. Thus, Option B is the correct and most efficient method for ensuring high availability and fault tolerance in this scenario. Which TWO statements are TRUE about Private IP addresses in Oracle Cloud Infrastructure (OCI)?
