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.

You can fast provision a virtual machine (VM) database (DB) system, using Logical Volume Manager (LVM) for storage management, only for Oracle Database versions 12.2 and greater1. This is because LVM is a new feature introduced in Oracle Base Database Service to enable faster provisioning of single-node VM DB systems1. LVM allows you to create logical volumes from physical disks and manage them more easily and efficiently1. LVM also reduces the storage overhead and improves the performance of the VM DB system1. LVM is not available for Oracle Database versions lower than 12.2, or for multi-node VM DB systems, or for bare metal DB systems1. For these cases, you must use Automatic Storage Management (ASM) for storage management, which is the default and recommended option for Oracle Base Database Service1. ASM provides high availability, scalability, and performance for Oracle databases by managing the disk groups and data files1. Therefore, the correct answer is B. References:

To consolidate two databases into a single Oracle Home, you need to perform the following actions1:

• Schedule a downtime window with the team using the 193B database. This is necessary because you need to stop the database service and detach the pluggable databases (PDBs) from the source Oracle Home before moving them to the target Oracle Home2.
• Use the Move Database option from the console to relocate the database to the target Oracle Home. This is the easiest and fastest way to move the database and its PDBs to a different Oracle Home. You can use the Oracle Cloud Infrastructure Console or the API to initiate the move operation, which will automatically copy the required files, update the configuration, and restart the database service in the target Oracle Home3.

Therefore, statements A and D are correct, and statements B and C are incorrect. Copying the sqlnet.ora and spfile from OH193_B to OH193_A and restarting PDBs is not sufficient to move the database to a different Oracle Home, as it does not update the Oracle Inventory, the Oracle Restart configuration, or the database registry4. Creating a new container database under OH193B and migrating the PDBs from 193B to 193A is not necessary, as you can move the existing PDBs directly to the target Oracle Home without creating a new container database5. References: 1: Oracle Base Database Services 2023 Professional, Section 4.2.2: Moving a Database to a Different Oracle Home 2: Base Database Service, Section 4.2.2.1: Prerequisites for Moving a Database to a Different Oracle Home 3: Base Database Service, Section 4.2.2.2: Moving a Database to a Different Oracle Home 4: [Oracle Database Administrator’s Guide], Section 2.4.1: Moving Oracle Database to a New Oracle Home 5: [Oracle Database Administrator’s Guide], Section 19.1.1: Overview of Pluggable Database Migration
