Explanation: Implement Active Data Guard in a single region, with the primary database in one availability domain and the standby database in another availability domain. -> Correct. Active Data Guard enables a high availability and disaster recovery setup by maintaining a synchronized copy of the primary database in a different availability domain within the same region, allowing for fast failover and minimal downtime. Deploy the databases on a single compute instance in one availability domain and use OCI Object Storage for database backups. -> Incorrect. This approach provides basic backup capabilities but lacks high availability and disaster recovery since it relies on a single compute instance in one availability domain. Use Oracle RAC across multiple regions for automatic failover and data redundancy. -> Incorrect. Oracle RAC (Real Application Clusters) does not natively operate across multiple regions; it is designed for high availability within a single data center or cloud region, making this an incorrect choice for a multi -region disaster recovery setup. Deploy databases on VMs in a single region and use OCI Block Volume backup to another region for disaster recovery. -> Incorrect. Using OCI Block Volume backups provides a method for data backup but does not offer an immediate failover or high availability solution, as significant manual intervention is required to restore the database in another region in the event of a disaster. An enterprise aims to enhance its application's availability and resilience by distributing traffic across multiple compute instances in different Availability Domains within the same region on Oracle Cloud Infrastructure (OCI). As an OCI Architect, what is the most effective solution you would recommend for achieving this goal?
Which of the following is not a recommended practice for enhancing the security posture of your Oracle Cloud Infrastructure (OCI) deployments?
OCI Web Application Firewall (WAF) -> Incorrect. While the OCI WAF protects web applications from common web exploits and threats, it does not directly facilitate the isolation and controlled inter - application communication as required by the scenario. OCI Dynamic Routing Gateway (DRG) -> Incorrect. A DRG is used to connect a VCN to external networks, such as the internet, an on -premises network, or other VCNs. While it's critical for broader network connectivity, it doesn't specifically address the scenario's requirements for isolation and secure data sharing among applications. A financial institution is exploring options to leverage Oracle Cloud Infrastructure (OCI) for its data analytics and processing needs. The institution requires a solution that can handle large volumes of data efficiently, provide real -time analytics, and support machine learning capabilities for predictive analysis. Which OCI service or feature would best suit their requirements?
When designing a highly available architecture on Oracle Cloud Infrastructure (OCI), you are considering the use of multiple Availability Domains (ADs) to deploy your application resources for redundancy and failover capabilities. Which two of the following options are essential considerations to ensure high availability of your application on OCI?
low latency, and high availability globally. They aim to migrate their application and data with minimal disruption to their service. Which of the following architectures would best suit their requirements on OCI?
of the following approaches would best achieve this goal?
