Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administration Exam Practice Test
Oracle Database 19c RAC, ASM, and Grid Infrastructure administration brings together clustered database operations and shared storage management. This practice page addresses topics such as ASM disk groups, allocation units, failure groups, and Oracle Clusterware resources, along with tools for examining cluster readiness and database-instance status.
Exam overview
About the Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administration Exam
RAC administrators need to understand how Oracle Clusterware coordinates resources across nodes and how services are managed as cluster resources. Practice questions also touch on the roles of the CRS daemon and voting files in cluster operation. ASM concepts include organizing disks into disk groups, selecting redundancy arrangements, using failure groups to account for storage fault boundaries, and understanding allocation units. Command-line work may involve ASMCMD for browsing ASM files and directories and ASMCA for storage administration. Cluster readiness checks are another operational task: administrators use CVU to assess prerequisites such as network configuration and shared storage before Grid Infrastructure installation. These concepts support practical decisions about cluster setup, storage layout, resource status, and troubleshooting. The available question signals reflect the practice bank’s vocabulary, not a confirmed official topic list.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
Which statement about ASM disk groups is correct?
Show answer
Correct answer: AAn ASM disk group combines storage devices into a managed storage pool. ASM files such as database datafiles and other database-related files can be stored in disk groups, subject to configuration and file type support.
What is the main benefit of using ASM failure groups when configuring disk group redundancy?
Show answer
Correct answer: AFailure groups represent sets of disks that may fail together, such as disks in the same enclosure. ASM uses this information when placing mirrored extents to reduce the impact of a shared failure.
Which Oracle Clusterware resource type is commonly used to manage a database service so it can be started, stopped, and monitored as a cluster resource?
Show answer
Correct answer: AA database service is represented as a Clusterware resource, commonly with the ora.service type, allowing Clusterware to manage its lifecycle and placement.
Which tool is designed to provide a command-line interface for browsing and managing Oracle ASM files and directories?
Show answer
Correct answer: AASMCMD is the command-line utility for working with ASM files and directories and performing selected ASM administration tasks. RMAN focuses on backup and recovery, while NETCA and DBCA configure networking and databases, respectively.
Which statement best describes an ASM allocation unit (AU)?
Show answer
Correct answer: BASM manages disk group space in allocation units, which are the fundamental units used to allocate space to files. An AU is not the same as an Oracle database block.
A cluster administrator wants to verify that nodes meet prerequisites before installing Grid Infrastructure, including checks related to network setup and shared storage. Which utility is intended for these cluster readiness checks?
Show answer
Correct answer: ACVU performs cluster readiness and configuration checks, including checks used before installation and during cluster administration. The other tools serve database recovery, data movement, or SQL interaction purposes.
An administrator needs to inspect the attributes and status of an ASM disk group from an Oracle command-line interface. Which tool is designed for ASM administration tasks?
Show answer
Correct answer: AASMCMD provides command-line commands for inspecting and managing ASM files, directories, and disk groups. DBCA creates databases, NETCA configures network components, and OPatchAuto is used for supported automated patching workflows.
How to use this practice test
Access the practice questions for free. When questions are available, a session presents up to 20 random items from this exam’s US Practice Tests bank; results appear after the session. Use missed answers to identify concepts to revisit, such as ASM storage structures, Clusterware resources, or cluster readiness checks.
Preparation tips
- Compare ASM redundancy choices and explain how failure groups map to independent storage failure boundaries.
- Practice distinguishing ASM disk groups, allocation units, and ASM file-directory operations; identify which command-line tools support each task.
- Review how Clusterware manages database services and what CRS and voting files contribute to cluster operation.
- Work through cluster readiness scenarios involving network and shared-storage prerequisites, then connect each check to the cluster setup task it supports.
- Use session results to revisit missed distinctions between database-instance status, ASM administration, and Clusterware resource status.
