350-701 Practice Question: A cloud operations team reports that after…
A cloud operations team reports that after enabling Cisco Secure Cloud Analytics (CSCA) for an AWS account, some legitimate traffic is being flagged as suspicious. The team has fine-tuned the ML models but false positives persist. Which additional step should they take?
⚠ Common exam trap
Candidates often confuse 'fine-tuning ML models' with 'adjusting alert thresholds' or 'adding more sensors,' when the correct approach is to use explicit whitelisting via custom alert rules to suppress false positives without compromising detection fidelity.

Correct answer & explanation
✓
Customize alert rules based on known good behavior
C is correct because Cisco Secure Cloud Analytics (CSCA) uses machine learning to establish a baseline of normal traffic behavior. When false positives persist despite fine-tuning ML models, the next logical step is to customize alert rules to explicitly whitelist known good behavior, such as trusted IP ranges or specific application flows. This reduces noise without disabling detection or lowering sensitivity, and it directly addresses the root cause: legitimate traffic that deviates from the baseline but is actually benign.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable ML-based detection
Why it's wrong here
Removes detection entirely.
- ✗
Increase the severity threshold
Why it's wrong here
May miss real threats.
- ✓
Customize alert rules based on known good behavior
Why this is correct
Whitelists known good traffic to reduce false positives.
- ✗
Deploy additional sensors in VPC subnets
Why it's wrong here
Increases visibility but not directly reduce false positives.
