Yeah, A is a classic use case for ICMP.

I thought ICMP used UDP? Guess I was wrong!

Aliza 12 months ago

Wait, B is false, right? ICMP doesn’t guarantee delivery.

Lewis 12 months ago

E is also correct, for sure.

Kenda 12 months ago

A and C are definitely true!

I vaguely recall that ICMP can report errors in IP processing, so E might be correct too, but I need to double-check that.

I practiced a question similar to this, and I think C is true because ICMP packets are indeed encapsulated within IP datagrams.

I'm not entirely sure, but I feel like ICMP packets don't guarantee delivery. That seems more like TCP's job, right?

Michell 1 year ago

I remember that ICMP is definitely used by the PING utility to check connectivity, so I think A is correct.

Okay, let me see. The question is asking about the difference between the original budget and the flexible budget, so it's probably related to variances. I'll go with C - Budget variance.

Hmm, I'm a bit unsure about this one. I know we need to communicate the changes effectively, but I'm not sure if selecting preferred senders is the right approach.

Okay, let me think this through step-by-step. The code is using an "alert" function, which will display a message when the page is loaded. So I think the answer is D - no changes needed, the alert message will appear when the page is loaded.

Hmm, I'm not too familiar with the Mac OS X file structure. I'll have to think this one through carefully.

This seems similar to a practice question we did on monthly expenses coverage, so I'm leaning towards option C or D.
