The three strategies to migrate Oracle Database to Oracle Cloud Infrastructure (OCI) are:

• Zero Downtime Migration: This is a tool that provides a simplified and automated migration experience, providing zero to negligible downtime for the production system. It supports migrating Oracle Database versions 11.2.0.4 and later, running on any platform, to any OCI Database service, including Exadata, Cloud@Customer, and Autonomous1.
• Migration Workbench: This is a feature of Oracle Enterprise Manager that provides a user interface to perform database migrations using various methods, such as Data Pump, Transportable Tablespaces, or Cross-Platform Transportable PDBs. It supports migrating Oracle Database versions 11.2.0.4 and later, running on any platform, to any OCI Database service, including Exadata, Cloud@Customer, and Autonomous2.
• GoldenGate: This is a software product that enables data replication and integration across heterogeneous databases and platforms. It supports migrating Oracle Database versions 10.2 and later, running on any platform, to any OCI Database service, including Exadata, Cloud@Customer, and Autonomous. It also supports bi-directional replication and zero downtime upgrades3.

B is incorrect, because autonomous migration is not a strategy to migrate Oracle Database to OCI, but a feature of Oracle Autonomous Database that allows you to migrate data from other sources, such as Oracle Database, MySQL, MongoDB, or Amazon S3, to an Autonomous Database instance using Oracle Data Pump or SQL Developer Web4.

C is incorrect, because Real Application Clusters (RAC) is not a strategy to migrate Oracle Database to OCI, but a feature of Oracle Database that provides high availability and scalability by enabling multiple instances to access the same database across a cluster of servers5.

One of the capabilities that the OCI Database Management Service provides using Database Groups is to execute a SQL query for the databases. Database Groups allow you to group your critical Oracle Databases, which reside across compartments, into a Database Group, and monitor them1. You can also create and schedule SQL jobs to perform administrative operations on a single Oracle Database or Database Group2. For example, you can run user-defined SQL jobs on database groups, such as conducting pre-release checks to databases under test3. Therefore, option A is the correct answer and the rest are incorrect. References: 1: Database Management for Oracle Databases - Oracle Help Center 2: Create and Execute Jobs on a Database Group (3:44) 3: Database Management Cloud | Oracle

Oracle Enterprise Manager and Service Console are two tools that can be used to monitor Exadata Database Service. Oracle Enterprise Manager is a comprehensive management solution that provides a single interface for monitoring and managing all Exadata, ExaDB-D and ExaDB-C@C systems, along with any other targets1. Oracle Enterprise Manager enables you to visualize storage and compute data, view performance metrics of your Exadata components, and perform administrative tasks such as patching, backup, and recovery1. Service Console is a web-based user interface that allows you to monitor and manage your Exadata Cloud Service instances2. Service Console provides information about the status, configuration, and utilization of your Exadata systems, and enables you to perform operations such as scaling, patching, backup, and restore2.

The other options are not valid tools for monitoring Exadata Database Service because:

• B. Oracle Management Cloud is a suite of cloud services that provides integrated monitoring, management, and analytics for applications, databases, middleware, and infrastructure3. Oracle Management Cloud is not specific to Exadata Database Service, and does not provide the same level of functionality and integration as Oracle Enterprise Manager4.
• C. Oracle Cloud Monitor is not a real tool, but a fictitious name. There is no such tool as Oracle Cloud Monitor in Oracle Cloud Infrastructure or Oracle Cloud Services.
• D. Oracle Internet Monitoring Suite (IMS) is also not a real tool, but a fictitious name. There is no such tool as Oracle Internet Monitoring Suite in Oracle Cloud Infrastructure or Oracle Cloud Services.

Updating a DB system on a virtual machine updates the Oracle Database software and the Grid Infrastructure software, but not the operating system. The operating system can be updated separately using the Upgrade option in the Console or the API. Therefore, statement D is false and the rest are true. References:
