Oracle Database Administration II — Question 91

Which three are performed by Oracle Automatic Storage Management (ASM) instances? (Choose three.)

Answer options

• A. mounting disk groups
• B. managing Allocation Units (AUs) for disk group content
• C. managing extent allocation for Oracle database segments
• D. acting as an I/O server to write data file blocks to ASM disks on behalf of Database Writer processes (DBWn)
• E. managing space allocation for Oracle ASM files
• F. acting as an I/O server to read data file blocks from ASM disks on behalf of database server processes

Correct answer: A, B, E

Explanation

The correct answers are A, B, and E because ASM is responsible for mounting disk groups, managing Allocation Units for the content of those groups, and overseeing space allocation for ASM files. Options C, D, and F are incorrect as they pertain to functions that involve segment management and I/O operations that are outside the core responsibilities of ASM instances.
