two distinct VCNs is a valid approach to maintain isolation while allowing for controlled interconnectivity as needed. Implementing separate Virtual Cloud Networks (VCNs) for production and development, without setting up any peering or connectivity between them. -> Incorrect. Implementing separate VCNs for each environment is a straightforward method to ensure complete isolation, as there is no direct network connectivity unless explicitly configured. In the process of optimizing performance for a set of applications running on Oracle Cloud Infrastructure (OCI), you decide to implement a caching solution. Which approach ensures high availability and fault tolerance for your cache layer while maximizing performance?
Unique Name, leading to misidentification and replication failure. Explanation: The standby database in the secondary region was accidentally configured with the wrong database Unique Name, leading to misidentification and replication failure. -> Correct. A mismatch in database Unique Names between the primary and standby databases would directly prevent Oracle Data Guard from correctly identifying and replicating data to the standby database, causing replication to fail. The security list rules in the primary region are misconfigured, blocking outbound data replication traffic. -> Incorrect. Security list misconfigurations could affect traffic but would unlikely be the sole cause of a complete replication failure, as inbound rules in the secondary region would play a more significant role. The VPN tunnel between the two regions experienced a temporary outage, interrupting the replication process. -> Incorrect. While a VPN tunnel outage might interrupt replication temporarily, Oracle Data Guard should resume replication automatically once connectivity is restored. The Oracle Data Guard configuration was set to use Maximum Performance mode, and transient network issues caused data loss during replication. -> Incorrect. Maximum Performance mode may tolerate some data loss during network issues, but it would not completely halt replication unless the issues are persistent and severe. A healthcare company is planning to migrate its sensitive patient data and associated database workloads from an on -premises data center to Oracle Cloud Infrastructure (OCI) to enhance data security and compliance with health regulations. The current environment utilizes a mix of relational databases and file storage systems containing decades of medical records. The migration strategy must ensure data integrity, comply with HIPAA regulations, and minimize downtime. After the migration, what approach should be taken to troubleshoot any issues that arise with the database and data migrations to OCI?
in identifying and troubleshooting migration -specific issues. Rely solely on OCI's automated email notifications for alerts on migration status and potential issues, without using additional monitoring or troubleshooting tools. -> Incorrect. While OCI's notifications can alert administrators to some issues, relying on them alone is insufficient for detailed troubleshooting and does not offer the proactive analysis needed for a smooth migration. An enterprise is migrating their on-premises workloads to Oracle Cloud Infrastructure (OCI) and plans to maintain a hybrid cloud architecture for the next few years. They want to ensure secure and private connectivity between their on -premises data center and OCI. Which of the following options is not a plausible method to achieve this requirement?
Directly migrate all databases using the highest compression ratio available to speed up the transfer process over the internet, without considering the potential impact on data integrity. -> Incorrect. While compression can speed up data transfer, using the highest compression ratio without evaluating its impact on data integrity and decompression times might risk data corruption and extended downtimes. Rely solely on manual snapshot -based backups for migrating databases to OCI, assuming this method will meet all regulatory compliance requirements regarding data protection. -> Incorrect. Manual snapshots may not capture all transactional data changes and might not meet certain regulatory requirements for data protection, especially for dynamic databases requiring point -in-time recovery. Bypass the use of OCI's pre-migration assessment tools, opting instead for a trial-and-error approach to troubleshooting post -migration issues as they arise. -> Incorrect. A trial -and-error approach is inefficient and risky, potentially leading to prolonged downtimes. Pre -migration assessments identify potential issues beforehand, allowing for a more controlled and successful migration process. An organization is looking to enhance its data management strategy by migrating several critical applications to Oracle Cloud Infrastructure (OCI). The applications have varying requirements, from heavy transaction processing to complex data analytics. Given the need to evaluate and implement both Autonomous and Base (VM/Bare Metal) Databases in OCI, which two of the following actions should be taken to ensure a successful deployment?
Consolidate all workloads onto a single Bare Metal DB System to maximize resource utilization and simplify network architecture. -> Incorrect. Consolidating all workloads onto a single system might seem efficient but can lead to performance bottlenecks and does not provide the workload -specific optimizations offered by Autonomous Databases. A software company is transitioning to Oracle Cloud Infrastructure (OCI) for better scalability and management of its application workloads. The company wants to implement a service that automatically adjusts compute capacity to maintain steady, predictable performance at the lowest possible cost. Which OCI service should be used to achieve this goal?
intervals. C. Implement OCI Functions to trigger data copy operations based on a scheduled time. D. Configure a Virtual Cloud Network (VCN) peering between regions to facilitate data replication. Explanation: Use cross -region replication to automatically replicate data across regions. -> Correct. Cross -region replication is a native feature of OCI Object Storage that automatically and asynchronously replicates data across regions, ensuring high availability and disaster recovery without the need for custom solutions. Deploy a custom application on compute instances in each region to manually copy data at regular intervals. -> Incorrect. While feasible, this method is more complex and error -prone compared to using built-in OCI features designed for this purpose. Implement OCI Functions to trigger data copy operations based on a scheduled time. -> Incorrect. OCI Functions can automate tasks, but for data replication across regions, OCI's native cross -region replication is more efficient and less complex. Configure a Virtual Cloud Network (VCN) peering between regions to facilitate data replication. -> Incorrect. VCN peering allows for network connectivity between regions but does not directly facilitate or automate data replication. Your organization is planning to leverage Oracle Cloud Infrastructure (OCI) for hosting a new, critical web application that demands high scalability and performance. To meet these requirements, you are considering various OCI services and features for the deployment strategy. Which of the following options is not an appropriate use of OCI services for optimizing the scalability and performance of the web application?
