Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure SSL Decryption policies to bypass trusted internal traffic or known safe applications.
To reduce Snort CPU load, administrators can disable unused intrusion rules, tune inspection policies, optimize SSL decryption rules to bypass trusted traffic, or adjust performance settings.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Convert all physical interfaces into switchports without IP addresses.
Why it's wrong here
Changing interface types does not mitigate Snort CPU load.
- ✓
Configure SSL Decryption policies to bypass trusted internal traffic or known safe applications.
Why this is correct
Bypassing resource-intensive SSL decryption for trusted traffic lowers CPU utilization.
- ✗
Disable the FTD kernel entirely and run Snort in standalone user-space loopback mode.
Why it's wrong here
Disabling the FTD kernel will crash the dataplane.
- ✓
Tune the Intrusion Policy to disable rules that are not applicable to the network environment.
Why this is correct
Disabling irrelevant rules reduces CPU inspection overhead.
- ✓
Optimize Access Control rules by placing frequently matched allow rules higher in the rule order with fewer inspection requirements.
Why this is correct
Optimizing rule order and bypassing inspection for trusted traffic reduces Snort processing.
