C and B are the ones that will output "hello world".

I definitely remember that the correct syntax for ENTRYPOINT should not have quotes around the command, so maybe C is right.

I feel like A and D might be wrong because of the quotes, but I can't recall the exact syntax rules.

I think I practiced a similar question where the exec form used commas, so maybe C is one of the answers?

I remember that ENTRYPOINT can take both exec form and shell form, but I'm not sure which one is correct here.

I'm feeling pretty confident about this one. The key is to use the exec form of the ENTRYPOINT instruction, which is the array syntax. Options A and C are the correct answers.

I'm a little confused by the wording of the question. Does it want us to choose the two options that will output "hello world", or the two options that are syntactically correct? I'll need to think this through carefully.

Okay, I've got this. The correct answers are options A and C, since they both use the exec form of the ENTRYPOINT instruction with the proper array syntax to execute the "echo hello world" command.

This looks like a straightforward Dockerfile question. I'll carefully read through the options and think about the proper syntax for the ENTRYPOINT instruction.

Hmm, I'm a bit unsure about the correct way to format the ENTRYPOINT command. I'll need to review the Dockerfile documentation to make sure I understand the differences between the string form and the exec form.

This looks like a straightforward NetSuite configuration question. I'll focus on identifying the two key settings that need to be enabled.

I think the answer is B - it applies the global policy. That seems like the most logical default behavior if a user-defined policy doesn't match.

This one seems pretty straightforward. As long as I set up the automatic rule correctly and configure the conditions, I should be able to get this done. Gotta stay focused though, can't afford any mistakes on the exam.

C and D are the way to go. I'm surprised that option E has 'World*' instead of 'World'. That's a bit of a giveaway that it's not correct.

I was a bit confused at first, but now I see that C and D are the way to go. The exec form is the way to go for ENTRYPOINT.

I agree with Dusti. C and D are the correct answers. The other options don't use the exec form or don't properly split the command.

I think the correct answers are C and D. The ENTRYPOINT instruction in a Dockerfile should be in the exec form, which is a JSON array, and the command should be split into individual elements.
