The correct answer is E. Ds. The Ds (Don't Suballocate) attribute prevents a specific file from using block suballocation even when suballocation is enabled at the volume level, which is useful for large database files where suballocation adds overhead without meaningful space savings.

File System and Storage Management

Question

Your organization uses a database application to store names and addresses used in direct-mail campaigns. As the demand for your company's products has grown, the database file, stored on volume DATA, has become very large. Which file attribute could you assign to the database file to prevent it from being suballocated even though block suballocation has been enabled on the DATA volume?

Options

  • AA
  • BDc
  • CDi
  • DDm
  • EDs
  • FIc

Why each option

The Ds (Don't Suballocate) attribute prevents a specific file from using block suballocation even when suballocation is enabled at the volume level, which is useful for large database files where suballocation adds overhead without meaningful space savings.

AA

The A (Archive) attribute marks a file as changed since its last backup and has no effect on block suballocation behavior.

BDc

Dc (Don't Compress) prevents file system compression on the file but does not influence whether block suballocation is applied.

CDi

Di (Delete Inhibit) prevents the file from being deleted and has no relationship to the suballocation mechanism.

DDm

Dm (Don't Migrate) prevents the file from being relocated to near-line storage by HSM and does not affect suballocation.

EDsCorrect

Ds (Don't Suballocate) is the NetWare per-file attribute that instructs the file system to store the file using full blocks rather than sharing partial blocks with other files. Applying it to the database file allows the rest of the DATA volume to continue benefiting from block suballocation while exempting this one file from the feature.

FIc

Ic (Immediate Compress) triggers compression of the file immediately rather than on a schedule and has no effect on suballocation.
