I thought it would be lower than 50%, interesting!

Definitely not 95%, that seems too high.

I'm guessing it's closer to 85% accuracy based on the ROC curve.

Wait, how can we be sure about the correct classifications?

Luisa 1 year ago

Looks like 25% false positives is pretty rough.

I feel like the correct answer is probably C or D, but I need to think about how the misclassification affects the true positive rate.

Katlyn 1 year ago

If 25% of non-purchasers are misclassified, that might suggest a higher true positive rate, but I can't recall the exact numbers for correct classifications.

I think I saw a similar question where we had to interpret the ROC curve, and it was about the true positive rate being higher than the false positive rate.

I remember something about ROC curves indicating true positive rates, but I'm not sure how that relates to the percentages given here.

Hmm, I'm a little unsure about this one. I know manual lenses have good iris control, but I'm not sure if they're the best in all lighting conditions. I might need to think this through a bit more.

Opening up the RDS instances to all IP addresses? That sounds like a huge security risk. I'll steer clear of that.

I'm a bit confused by this question. The options all sound like they could be part of a product owner's responsibilities. I'll have to review my notes on the product owner role to decide which one best captures the core responsibility.

Okay, let's see... The question is asking about tools for performing a DNS zone transfer attack. I remember learning about Dig, Host, and NSLookup in class, so those are likely the correct answers. I'll go with those.

I remember studying the different solutions, but I'm not sure if FlexStack is part of Cisco's offerings.
