Public IP addresses should be assigned to each compute instance to ensure they are directly accessible from the internet for redundancy. -> Correct. Assigning public IP addresses to each compute instance for direct internet access is not required for high availability and can introduce security risks. Redundancy and availability should be managed through internal networking and load balancing, not direct internet access to each instance. The Load Balancer must be configured to distribute traffic across instances in multiple Availability Domains. -> Incorrect. Utilizing a Load Balancer to distribute traffic across instances in multiple ADs is essential for high availability and is a standard practice. Application instances must be deployed in at least two different regions for geographic redundancy. -> Incorrect. While deploying across regions adds geographic redundancy and is recommended for disaster recovery, it is not strictly necessary for high availability within the scope of this scenario. A company plans to migrate its on -premises Oracle databases to Oracle Cloud Infrastructure (OCI) to enhance performance and reduce costs. The databases vary in size from 2 TB to 20 TB and are critical for daily operations. The company seeks minimal downtime and aims to ensure data integrity during the migration process. Which migration strategy should the company use to meet these requirements?
expected load times. Initial checks confirm that the application components and OCI services are functioning as intended. What might be the underlying issue affecting performance?
In a scenario where a global retail company seeks to enhance its customer experience by leveraging big data analytics and machine learning models hosted on Oracle Cloud Infrastructure (OCI), while maintaining its core e-commerce platform in an on-premises VMware environment, which strategy would best enable the integration of these environments to ensure high availability, scalability, and seamless data processing between on -premises systems and OCI?
C. Implement Active Data Guard with cross -region replication to a standby database in a different region. D. Set up a scheduled script to export the database to OCI Object Storage in another region periodically. Explanation: Implement Active Data Guard with cross -region replication to a standby database in a different region. -> Correct. This approach ensures the database is highly available and recoverable by replicating it to a different region, offering protection against regional outages. Deploy the database in a single Availability Domain and use OCI Object Storage for daily backups. -> Incorrect. While Object Storage provides durable backup storage, relying on a single Availability Domain does not ensure high availability during a regional outage. Utilize Active Data Guard to replicate the database across multiple Availability Domains within the same region. -> Incorrect. This improves availability within the region but does not protect against regional outages. Set up a scheduled script to export the database to OCI Object Storage in another region periodically. -> Incorrect. Periodic exports might not capture the latest data changes and do not ensure the database's high availability or quick failover capability. In the process of optimizing their cloud infrastructure for high performance and efficiency, EFG Company is exploring options for their Oracle Cloud Infrastructure (OCI) deployment to achieve optimal compute resource utilization. They need a solution that automatically adjusts compute resources based on the workload demand to ensure cost -effectiveness while maintaining performance. Which OCI feature best supports this requirement?
In setting up Oracle Cloud Infrastructure's (OCI) FastConnect to enhance connectivity between your on - premises network and OCI, you've noticed intermittent connectivity issues that affect application performance. Before deploying, you confirmed that all physical and logical connections were established correctly according to OCI documentation. What could be the primary cause of these intermittent connectivity issues?
some level of fault tolerance, it does not fully leverage geographic distribution to minimize latency for a global audience. Implement the application solely on OCI's Container Engine for Kubernetes in a single region, relying on its built -in scalability features. -> Incorrect. While Kubernetes provides scalability, a single -region deployment does not address the need for geographic distribution to serve a global audience with minimized latency. Utilize a third -party global load balancer outside of OCI to route traffic to an OCI deployment in a single region, with no specific scalability features configured. -> Incorrect. Relying on external traffic management without leveraging OCI's native scalability and geographic distribution capabilities does not optimally serve a global audience or ensure fault tolerance. An enterprise plans to migrate its legacy applications and databases from an on-premises data center to Oracle Cloud Infrastructure (OCI) to improve scalability, performance, and disaster recovery capabilities. Which two steps are critical in ensuring a successful migration of these workloads to OCI? Select two.
