Answer / guest
Answer: B
The objective of parallel running is to verify that the new
system produces the same results as the old system. The
verification of functionality is through acceptance testing,
while resolving errors in programs is accomplished through
system testing. Verifying that the system can handle the
production load may be a secondary outcome of a parallel
run, but it is not the primary purpose. If it were the
primary purpose, it would be a stress test probably run in
the test environment.
