Alright, let's see... I'm pretty sure A, C, and D are the right answers. The default snapshot interval, retention period, and ability to disable snapshots are all important aspects of AWR. As for the statistics level and tablespace, I'm drawing a blank on those. Guess I'll have to do some more studying!
Haha, this question is a classic! Everyone knows that the correct answers are B, C, and D. The collection level, retention period, and ability to disable snapshots are all key features of AWR. I don't know why they even included the other options - they're just trying to confuse us!
Hmm, I think A, C, and D are the correct answers. The default snapshot interval is 60 minutes, the retention period is 7 days, and we can disable the snapshots. I'm not too sure about the statistics level or the tablespace, though.
B and D seem right to me. The collection level is determined by the STATISTICS_LEVEL parameter, and we can disable the taking of snapshots. But I'm not sure about the default retention period or the tablespace used.
