I completed exercise 1 today on Bb, and the results aren’t good. It’s clear that I need to go back and reread Chapters 1 and 2. I obviously didn’t pick up all the details. My score was 22/30. I missed 7 questions (one was 2 points). That’s not acceptable. I’ll go back and reread those chapters and retake the test to improve my score.
The second time around, I scored a 27/30. This time, I only missed two questions (one was 2 points). The questions I missed are the following:
- Which organizational function should set database standards? I said “technical services,” but the answer was “none of the above.” I went back and checked and it’s the database administrator whose job is to set database standards. This makes sense as they are the ones with database knowledge.
- The most common source of database failures in organizations is. I said “lack of planning,” but the answer was “failure to implement a strong database administration function.” This makes sense because databases require continued monitoring and administration through their lives.
I took the test again a third time, and this time scored 30/30. I’m satisfied that I fully understand all the questions and answers now.
