Which two statements are true about the Oracle Cloud Infrastructure (OCI) Monitoring tools available for Base Database Service Virtual Machine DB Systems?

• A.Oracle Cloud Agent collects OS, VM, and Database metrics, which are reported to the OCI Monitoring service and can be visualized via charts or dashboards.
• B.Customer-installed monitoring agents are strictly prohibited on Base Database Service Virtual Machine DB Systems to maintain security compliance.
• C.Only Oracle Cloud Agent metrics can be used for metric data charting, alarming, and notifications. OS metrics can only be collected.
• D.DB system performance events are only accessible via the Oracle Database Enterprise Manager interface, and these events cannot be integrated with OCI monitoring tools.
• E.The OCI Monitoring service allows users to define alarms based on metric thresholds, triggering notifications via OCI Notifications service.

Which statement BEST describes the primary architectural distinction between Exadata Database Service and a traditional Oracle Database deployed on virtual machines in the cloud?

• A.Exadata Database Service exclusively supports Oracle RAC, while traditional cloud deployments can support both single-instance and RAC databases.
• B.Exadata Database Service utilizes only virtualized compute nodes, while traditional deployments use bare metal.
• C.Exadata Database Service integrates specialized, high-performance storage servers and a high- bandwidth, low-latency RDMA over Converged Ethernet (RoCE) network, optimized for database workloads, which are not present in typical cloud VM deployments.
• D.Exadata Database Service uses a completely different SQL parsing engine compared to a traditional Oracle Database.

You need to implement a backup and recovery strategy for your MySQL HeatWave Database System. What is the recommended method for backing up and restoring your HeatWave cluster?

• A.Manually copying the data files from the HeatWave cluster's storage.
• B.Relying solely on MySQL replication to another MySQL instance.
• C.Using the MySQL Enterprise Backup tool directly on the HeatWave nodes.
• D.Using the OCI Object Storage service for storing manual database dumps.
• E.Utilizing OCI Database backups, which include both the MySQL Database System and the HeatWave cluster.

When migrating a MySQL instance to MySQL HeatWave, which method generally provides the MINIMAL downtime for large databases?

• A.Utilizing MySQL replication to replicate data to the HeatWave instance and then performing a switchover.
• B.Creating a physical backup using MySQL Enterprise Backup and restoring it to the HeatWave instance.
• C.Using a third-party ETL tool to extract, transform, and load the data into the HeatWave instance.
• D.Using mysqldump to create a logical backup and restoring it to the HeatWave instance.
• E.Copying the data files directly from the source instance to the HeatWave instance.

What is the MOST effective method to minimize the recovery time objective (RTO) for a BaseDB database in the event of a complete DB system failure, assuming both cost and complexity are important considerations?

• A.Relying solely on regular full database backups.
• B.Using Oracle Data Guard with asynchronous replication to a different availability domain within the same region.
• C.Implementing a custom script to regularly copy data files to a secondary block volume.
• D.Using Oracle Data Guard with synchronous replication to a remote region.
• E.Performing frequent incremental backups with block change tracking enabled.
