Yeah, push is the way to go here!

I thought unshift adds to the start, not the end?

Wait, is namesArr [4] ''Hank''; even valid?

Definitely option B! That's the right way.

You can use namesArr.push('Hank'); to add to the end.

I remember that unshift adds to the beginning, so that can't be right. I think push is definitely the way to go here.

I'm not sure about the syntax in option B, though. Shouldn't it be namesArr.push('Hank') instead of namesArr push ('Hank');?

I practiced a similar question where we had to add an element to an array, and I believe the correct method was push.

I think we need to use a method to add an item to the end of the array, but I can't remember if it's push or something else.

Okay, let me think this through step-by-step. The question is asking about the deviation between the measured and actual values. That sounds like it's referring to the accuracy of the measurement, so I'm going to go with A. Bias.

This looks pretty straightforward. I think I'll go with option D - "name = input()" since that seems to be the most direct way to accept user input and store it in a variable.

I've set up a few of these connections before, so I've got a good handle on this. The key things are the Instance Hostname, the Keystore Password, and the Business Manager Username.

I'm a bit confused here. The question mentions that the pool members are listening on port 8080, but the monitors should work on port 9080? That doesn't seem to match up. I'll need to think this through carefully.
