Oracle Database Administration 2019 Certified Professional — Question 81

Which two statements are true regarding ASM Dynamic Volume Manager (ADVM)? (Choose two.)

Answer options

• A. An ADVM volume is individually named and can contain only one file system.
• B. ADVM extends ASM by providing a device driver interface to storage backed by an ASM disk group.
• C. File systems contained in ADVM volumes may only contain database files.
• D. Only one ADVM volume can be created in an ASM disk group.
• E. To create an ADVM volume, disk group attributes COMPATIBLE.ASM and COMPATIBLE.ADVM must be minimally set to 12.1.<.span>.

Correct answer: A, B

Explanation

The correct answers are A and B because an ADVM volume is indeed uniquely named and can only host one file system, and ADVM extends ASM by providing a device driver interface to ASM disk groups. Options C and D are incorrect as ADVM volumes can contain various types of files, not just database files, and multiple ADVM volumes can be created in a single ASM disk group. Option E is also wrong since the compatibility settings are not strictly limited to 12.1.
