Use references rather than sensitive values
This fictional recovery format requires data archive D, format manifest M and recovery-material reference K. D and M are present; K is unavailable in the rehearsal environment. The exercise defines only material sufficiency, not a real encryption algorithm or security recommendation.
| Reference | Required | Available |
|---|---|---|
| D archive | Yes | Yes |
| M manifest | Yes | Yes |
| K recovery reference | Yes | No |
Require all three materials
- List the required conjunction
- Check usable availability
- Stop before claiming opened data
Do not place the underlying recovery value into the shared worksheet.
Is the archive sufficient for this rehearsal?
Show the worked answer
No. Two of three materials are available, but the rule requires all three. K is the missing prerequisite; an existing data archive is not yet opened evidence.
Keep an unopened copy distinct
| Case | Decision | Reason |
|---|---|---|
| D+M only | Insufficient | K absent |
| D+M+usable K | Material set sufficient | Execution still to verify |
Obtain authorised usable access to the reference in the chosen rehearsal environment, then verify the opened synthetic records. The worksheet retains reference/status only.
