Actual exam question for SAS's A00-240 exam

Question #: 55
Topic #: 9

What is a benefit to performing data cleansing (imputation, transformations, etc.) on data after partitioning the data for honest assessment as opposed to performing the data cleansing prior to partitioning the data?

AIt makes inference on the model possible.

BIt is computationally easier and requires less time.

CIt omits the training (and test) data sets from the benefits of the cleansing methods.

DIt allows for the determination of the effectiveness of the cleansing method.

Option D makes the most sense to me!

I think it’s just easier computationally, not sure about effectiveness.

Wait, so cleansing before could mess up the test data?

Cleansing after partitioning helps assess model performance better.

I vaguely remember that performing cleansing before partitioning can skew results, so maybe option D is the right choice for assessing effectiveness.

I feel like option C could be a trap answer since it mentions omitting benefits, but I can't recall the exact reasoning behind it.

I think option D sounds familiar because it relates to evaluating the cleansing methods' impact on model performance, but I might be mixing it up with another question we practiced.

I remember discussing how data cleansing after partitioning helps to avoid data leakage, but I'm not entirely sure which option reflects that best.

I feel pretty confident about this one. Modeling and testing are all about identifying and mitigating technical risks, so Cyber security risk is the most likely answer here.

This seems straightforward. NSTISSP No. 11 is the policy that mandates NIACAP for classified systems, so I'll go with that.

Ah, I know this one! The broker-dealer has to buy in the customer after 15 days, right?

Okay, I think I've got this. Negotiating with the key stakeholders to find a compromise seems like the best approach here. I'll also consider the other options, but that one stands out to me as the most appropriate solution.

Okay, I think I've got this. The command should be "kubectl get events --field-selector involvedObject.name=api" to display the events for the specific deployment. Let me double-check that before answering.
