Sniffing traffic sounds cool, but is it really necessary?

Wait, are we really resetting thresholds? That seems risky.

But shouldn't we also look at the traffic itself? Option B makes sense too.

Sniffing the traffic could help, but I wonder if it’s more about understanding the alerts first before diving into the traffic analysis.

I practiced a similar question where we had to balance false positives and false negatives. I feel like minimizing false positives is crucial here.

I think analyzing the alerts to reduce false positives makes sense, especially since too many alerts can lead to alert fatigue.

Hmm, this is a tough call. I'm tempted to go with option B and analyze the traffic to minimize false negatives, but I can see the logic in option C as well. I'll have to think this through carefully.

Okay, let's think this through. If there are a high number of alerts, we probably want to focus on reducing false positives rather than false negatives, so I'd go with option C.

Resetting the alert threshold based on peak traffic sounds like a good starting point, but I'll need to consider the other options as well.

I'm a bit confused on this one. Resetting the alert threshold based on peak traffic seems like it could just mask the real issues. I think I'd lean towards analyzing the alerts to minimize false positives.

I'm pretty sure the answer is A, updating the major release number in the WSDL namespace name. That's a common way to indicate backwards-compatible changes in TIBCO services.

Minimize false negatives, eh? Sounds like we need to find that sweet spot between catching all the bad guys and not drowning in a sea of alerts. Careful not to fall for the 'more is better' trap!
