I’m confused, why not just use the context object for everything?

Totally agree with A, standard output is the best for logging in Lambda!

Wait, can you really log to a file in Lambda? Isn't it ephemeral?

I think C makes more sense, using the event object is better.

Option A is the way to go! Context object has the request ID.

I’m a bit confused about whether to use the context or event object for the request ID. I need to double-check that part.

I practiced a similar question where logging to standard output was recommended. I wonder if that's the best option here too.

I think the event object is used for the input data, so the context object is probably the right choice for the request ID.

I remember that the context object contains the AWS request ID, but I'm not sure if it should be logged to standard output or a file.

I vaguely recall that the request ID is in the context object, but I can't remember if we should log to standard output or a file. I hope I chose the right option!

I’m a bit confused about whether to use the context or event object for the request ID. I thought both could work, but I need to double-check.

I think we practiced a similar question where we had to log events in a Lambda function. I feel like standard output is the right choice for logging.

Ah, I remember learning about this in class. The properties files are used to store global variables and default language translations, so I'll go with options B and C.

My gut is telling me the management tenant. I remember it being a centralized location for managing resources, but I could be mixing it up.

I'm a little confused by the wording of the question. Does the "What happens after the code block executes?" mean we need to consider any potential side effects or issues that could arise? I'll have to think this through carefully.

Hmm, I'm a bit unsure about this one. I know build tools are used in software development, but I'm not entirely sure of their exact purpose. I'll have to think this through carefully before selecting an answer.
