After signing in to My Services, an administrator needs to check how much of the purchased Database Cloud Service capacity has been consumed this month and then drill into a specific database deployment to open a Service Console for it.
Which sequence correctly describes what the administrator does?
The My Services Dashboard presents a tile per subscribed service showing usage relative to the purchased quantity or balance. Clicking the Database Cloud Service tile opens the service console listing all deployments, and selecting a deployment opens its Oracle Database Cloud Service Console where you can manage backup, patching, and access rules. SQL Developer and EM Database Express operate at the database level only and do not report account usage; the Compute console shows compute resources, not Database Cloud Service subscription usage.
An architect is comparing service levels for a new project. The team wants the cloud tooling to automatically create a database, configure backups to cloud storage, and enable one-click patching immediately after provisioning, without any manual installation steps.
Which combination should the architect select when creating the deployment?
The Database Cloud Service level provisions a fully created and configured database with the complete set of cloud tooling: automated backup and recovery to cloud storage, patching, and snapshot/cloning features. The Virtual Image service level only installs the software binaries in an unconfigured state; you must create the database yourself and the automated backup/patching tooling is not available. Option D disables backups, which contradicts the requirement.
A customer wants full operating system root access (via the opc user and sudo) to the compute node hosting their database so they can install a custom agent, and they also want Oracle to fully manage the underlying infrastructure. They choose the Database Cloud Service service level.
Statement: With the Database Cloud Service service level, the customer receives SSH access to the compute node and root privileges through sudo, and is responsible for administering the database and OS.
True. Database Cloud Service (including the Virtual Image option and Exadata-based service levels) gives the customer SSH access as the opc user, with root privileges available through sudo, and the oracle user for database administration. The customer is responsible for database and OS administration, while Oracle manages the underlying cloud infrastructure. This is the key differentiator from Schema Service style offerings, where no OS-level access is provided.
A DBA must apply the latest quarterly patch (Patch Set Update) to a single-instance Oracle Database Cloud Service deployment. Before applying it, the DBA wants to confirm that the deployment has enough free space and that no conflicting condition exists.
Which action should the DBA take from the Oracle Database Cloud Service console?
The Patching page for a deployment lists available patches and offers both Precheck and Patch actions. Precheck verifies free space, database status, and other prerequisites without changing anything, and reports issues before you commit. Manual opatch use is not the console-supported flow and bypasses the cloud tooling metadata; storage scaling is not automatically required; and in-place patching (with automatic rollback capability) is fully supported.
You are creating a new Oracle Database Cloud Service deployment using the Database Cloud Service service level with Enterprise Edition. During the Instance Details step you specify a Usable Database Storage size of 100 GB.
Which statement correctly describes the storage volumes that the tooling allocates and attaches to the compute node?
The Database Cloud Service tooling provisions multiple block storage volumes: a boot volume for the OS image, a software volume mounted at /u01, a data volume mounted at /u02 sized from the Usable Database Storage value, a fast recovery area volume at /u03 (when backups to storage are configured), and a small redo log/configuration volume at /u04. Keeping software, data, and FRA on separate volumes allows independent scaling and recovery. The other options misstate this multi-volume layout.
