Exam CS0-002 topic 1 question 325 discussion

This answer has to be D. There's low traffic on Wednesday, outbound traffic maxes out at 300Mbps but Thursday has around 1000Mbps of outbound traffic at midnight, when the office is closed.

thank you guys for helping me understand this!

It is D. There is a HUGE fall off at 1900 on inbound connections, and around 2100 there is a sharp increase of outbound traffic with no inbound traffic increase too match. Meaning whatever is being passed is only moving in 1 direction. Thus warrants further investigation.

As stated below over the course of several comments: Wednesday looks the most different but Thursday's is the only one where outbound data Far exceeds inbound data. It's also the only day with a lot of outbound data if you actually look at the numbers on the scale. The only thing that deterred me was that Thursday's looked like backup however the question specifically states "backups were not performed during this time". Also for an exam of this difficulty, for me it's just too easy that Wednesday is the answer as the other three days look so similar at a glance. We all know what CompTIA can be like for making us thoroughly read the question and this is another example of that. I'm going with D

Whilst Wednesday looks lke the odd one out, when you look at how many Mbs of data are flooding out of the network then surely the early and late hours of Thursday are the biggest concern... Outbound traffic is heavy and far exceeding inbound at these times
