Friends:
Here is a question taken straight from the Couchman text CD. I cant understand why the correct answer is given. I understand the meanings of pctfree / pctused, but I don't know which one is the least desirable:
"Which of the following choices identifies block space utilization settings that are never appropriate under any circumstances:
A: pctfree 5, pctused 90
B: pctfree 20, pctused 70
C: pctfree 15, pctused 80
D: pctfree 10, pctused 40
The correct answer is C. Why ? (I chose B)
Thanks- B. |
