Q: 5
Enhancing and cleaning data is an important action during which phase of CPMAI?

C . Had something like this in a mock and Phase III was all about data prep, cleaning, and enhancement before modeling. Makes sense since prepping the data is key at that stage. Open to other takes but C fits best here.
I get why people keep picking C, but D feels right to me for this one.
D . Data enhancement can also happen after modeling when you notice issues, so I think Phase IV fits. Not 100 percent, but seen similar traps in past questions.
Probably D, since enhancement sometimes happens after initial modeling tweaks, not just before modeling.
Option D is tempting, but I think C since core cleaning typically happens in Phase III.
I think C, main data cleaning and enhancement is in Phase III. Open if anyone thinks otherwise.
Hard to say, D, since sometimes enhancement happens after initial modeling too.
C , main trap is D since you might fix data after modeling, but core cleaning/enhancement is always Phase III.
C vs D? I saw a question like this in a different set and most picked C because main data cleaning/enhancement is typically in Phase III, right before modeling. But you do sometimes see people go with D since cleanup can happen after. Not 100% so open to being wrong here.
C tbh. Phase III in CPMAI is where the heavy lifting on data prep, cleaning, and enhancement goes down, just before modeling. I get why some might pick D since tweaks happen later, but the bulk of cleaning is definitely in III. The wording here points to main prep not post-modeling corrections. Disagree?
