Are we sure it's not an issue with error handling? Seems odd.

I disagree, I don't think A is the issue here.

I think B could be a factor too. 10-MB limit is pretty low!

Definitely D and E. Sounds like the subscriber is lagging.

I keep thinking about error handling. If the subscriber code isn't catching runtime errors properly, could that be causing the slowdown without logging any errors?

I feel like we had a practice question about message limits in Pub/Sub. Could the total outstanding messages exceeding the 10-MB max be a factor here?

I'm not entirely sure, but I think if the subscriber isn't acknowledging messages, that could lead to a backlog.

I remember we discussed something about subscriber performance in class. Could it be that the subscriber code just can't keep up with the message rate?

I'm a little confused by the mention of SAFe principles. Does that mean the Scrum Master's role goes beyond just Scrum? I'll need to think about how that fits into the answer.

I think the most important thing is that the teams are all on the same page about what "Done" means, so that the final product is ready to be released. Option D seems to capture that best.

Okay, I've got this. Cisco TrustSec uses software-defined segmentation to manage network access and security policies. That sounds like exactly what the question is asking about. I'm confident this is the right answer.

Okay, I think I can handle this. The key is to use the formula for the 90% confidence interval for the mean when the population standard deviation is known.
