JNCIA-SEC Content Security Practice Question
You notice that CPU utilization on the SRX Routing Engine spikes significantly whenever large archives are downloaded through the UTM antivirus inspection engine. Which architectural adjustment or feature configuration helps mitigate control plane impact during stream scanning?
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
✓
Offloading stream scanning buffers and ensuring fast-path processing on Security Processing Cards (SPCs).
Stream scanning on SRX devices leverages specialized hardware (such as SPCs / Flow Processing Cards) where applicable, but tuning stream buffer sizes or utilizing hardware acceleration helps manage resource utilization.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disabling stateful inspection across all zones.
Why it's wrong here
Disabling stateful inspection breaks firewall operations.
- ✓
Offloading stream scanning buffers and ensuring fast-path processing on Security Processing Cards (SPCs).
Why this is correct
Leveraging SPCs keeps traffic inspection in the data plane rather than stressing the Routing Engine control plane.
- ✗
Moving all UTM antivirus processing to the Routing Engine CPU.
Why it's wrong here
Moving UTM to the Routing Engine would worsen CPU spikes.
- ✗
Configuring static routing for all HTTP traffic.
Why it's wrong here
Routing does not impact antivirus processing loads.
