I thought a scatter plot would work too?

A trend plot of empirical logit is the way to go!

I vaguely remember something about odds ratios, but I don't think a box plot would help with non-linearity in this context.

I feel like the logistic regression plot of predicted probabilities might be the best option here, but I can't recall all the details.

I remember practicing with scatter plots, but I don't think that's the right choice for this question.

I think we discussed using a trend plot of empirical logit versus a predictor variable for checking non-linearity, but I'm not entirely sure.

Easy one - the FQDN is definitely a valid way to specify the SMTP server address.

Wait, do β-blockers affect how we interpret exercise test results? I'm not totally sure about this one.

Hmm, I'm a bit confused about the difference between credential caching and seamless access. I'll need to review my notes on authentication providers to answer this one confidently.

I remember a similar question in practice about service contracts, and I think forcing all consumers through a central contract makes sense. That sounds like it could limit direct access issues when the database changes.

I think the DSCP value might be one of the answers since it relates to prioritizing traffic, but I'm stuck between that and something else.

I'm not entirely sure about this one. I'll have to review my notes on AWS Global Accelerator.
