View the Exhibit and examine the sample Automatic Database Diagnostic Monitor (ADDM) report.
Which statement is true about the report?
A.
The sum of impacts under recommendations in Finding 2 cannot exceed 100%.
B.
It is possible that the sum of impacts under recommendations in Finding 2 can exceed 100%.
C.
The recommendations regarding “buffer busy” wait cannot appear more than once in the report.
D.
The sum of impacts of recommendation 2 in Finding 1 and recommendation 2 in Finding 2 cannot exceed 100%.
B seems okay
When a specific problem has multiple causes, ADDM may report multiple findings. In
this case, the impacts of these multiple findings can contain the same portion of DB
time. Because performance problems can overlap, summing the impacts of the
reported findings can yield a number higher than 100% of DB time.
