You are going to create an ACFS Filesystem for use as a staging area for data loads. Examine the following commands: What steps and in which order should they be executed?

Options

• A6, 2, 1, 8, 4, 5
• B6, 8, 3, 4, 2, 1
• C6, 3, 1, 9, 7, 8
• D6, 1, 2, 7, 5, 8

• A
  84% (21)
• B
  4% (1)
• C
  8% (2)
• D
  4% (1)

Explanation

Option A (6, 2, 1, 8, 4, 5) follows the only logical dependency chain for ACFS creation: you must initialize/verify the ASM environment first (6), then create the ADVM volume (2), format it as ACFS with mkfs (1), create the OS mount point directory (8), mount the filesystem (4), and finally register it with Oracle Clusterware (5). Each step produces output that the next step depends on - you cannot format a volume that doesn't exist, or mount a filesystem that hasn't been formatted.

Option B fails because it attempts to create the mount point (8) and mount (4) before the volume is even formatted, skipping the mkfs step entirely. Option C introduces step 9 and step 7 in positions that violate the volume-before-format-before-mount dependency, using steps that don't fit the required sequence. Option D runs the format command (1) before creating the underlying volume (2), which would fail immediately since there is no volume to format yet.

Memory tip: Think of the acronym "VCFMMR" - Verify ASM → Create volume → Format → Make mount point → Mount → Register with Clusterware. Any answer that puts "Format" before "Create volume," or "Mount" before "Format," is automatically wrong.
