Option C could add unnecessary complexity, though.

Wait, can you really use apt on Heroku? That sounds odd!

Not sure about that, wouldn't a REST API be more flexible?

I agree, a custom buildpack is the way to go!

Option D seems like the best choice for Heroku.

I feel like option A might be too slow since fetching from cloud storage could add latency. I think D is probably the most efficient way to go.

I practiced a similar question where we had to install dependencies on Heroku, but I can't recall if using sudo is allowed. Option B feels off to me.

I think option C could work, but it seems like a lot of extra overhead to maintain an on-premise server just for that library.

I remember something about using buildpacks in Heroku, so option D sounds familiar, but I'm not entirely sure if it's the best choice.

The custom buildpack option seems like the most reliable and maintainable way to handle this requirement on Heroku.

Continuing to host wkhtmltopdf on-premise and building a REST API seems like an overly complex solution for this use case.

Installing the dependency directly in the .profile file could work, but I'm not sure if that's the best approach for a Heroku deployment.

Hmm, I'm not sure about that. Fetching the library from cloud storage on dyno restart might be a simpler solution.

This seems like a straightforward question. I would recommend using a custom buildpack to install wkhtmltopdf on the Heroku dyno.

Wait, I'm a bit confused. Isn't there an option to just delete the DataFrame directly?

I think the solution needs at least two solid state drives for best performance, but I can't recall the exact requirement for logging.

Okay, let me break this down step-by-step. The question is asking about the background items auditors should review, and the options are A) program/organizational goals, B) organizational data, C) A and B, or D) none of the above. I think C is the best answer, since both the purpose/goals and the organizational data would be important for an auditor to understand.

I remember discussing the consequences of a security officer's actions in our last class. I think they could face criminal charges, but I'm not entirely sure if that covers everything.

Key strategy: Don't overthink it. Read the statement carefully and trust your first instinct about procurement rules.

CusQuentin buildpack? More like cusQuentin headache! I'm just going to print all my reports on paper and hand-deliver them. Problem solved.

Installing the dependency from .profile? That's just wrong. Who uses sudo on Heroku anyway? CusQuentin buildpack is clearly the winner here.

I'd avoid hosting the library on-premise and building a REST API. That adds unnecessary complexity and maintenance overhead. Go with the custom buildpack!

That's a valid point, Gilma. Option A could be a good choice for ensuring easy access to wkhtmltopdf on Heroku.
