Wait, so it marks packets as 'discard eligible'? That sounds harsh!

I thought WRED used just one slope, not two?

Totally agree, but it doesn't disable TCP slow-start!

I definitely recall that WRED marks packets as 'discard eligible,' but I’m unsure if it also polices the buffer pool like option E suggests.

I think option C sounds familiar; I practiced a question about configurable slopes in WRED, but I can't recall the details.

I remember WRED monitoring buffer space, but I'm not sure if it's just over time or also in real-time.

I feel like WRED does something with shared buffer utilization, but I can't remember if it uses individual queue depth or not.

Okay, let me see. Smoke tests, acceptance tests, and usability tests all sound like they could be automated, but I think unit tests are the most common type of automated code testing. I'll go with A.

Hmm, I'm a bit unsure about this one. The options seem pretty similar, and I want to make sure I understand the differences between them before selecting an answer.

Hmm, I'm a bit unsure about this one. Do I need to set up a load balancer first, or can I just enable CDN on the bucket? I'll have to review the options carefully.

Hmm, I'm a bit unsure about this one. I'll need to think through the different style options and how they might apply to the given markup.
