156-315.81.20 Performance Tuning (SecureXL/CoreXL) Practice Question
An administrator wants to prioritize specific high-bandwidth traffic for acceleration. Which command can influence SecureXL to favor these flows?
⚠ Common exam trap
Candidates often search for a non-existent 'accelerate-this-flow' command, failing to understand that SecureXL acceleration is a passive result of policy design rather than an active per-flow command.

Correct answer & explanation
✓
Adjusting the security policy to remove features that inhibit acceleration.
While there isn't a single command to 'force' acceleration for specific flows, administrators can optimize the policy to ensure these flows don't hit features that disable acceleration. By isolating high-bandwidth traffic into rules that avoid incompatible features (like certain IPS or logging), the administrator creates an environment where SecureXL templates are consistently created. This is a vital performance tuning skill, as it directly impacts the gateway's ability to handle high-throughput traffic at line rate.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
fwaccel enable -p <priority>
Why it's wrong here
There is no 'fwaccel enable -p' command. This is a common misconception among administrators. SecureXL does not operate on a per-flow priority basis in this manner, and trying to use non-existent commands will not change the behavior of the acceleration engine or the performance of traffic.
- ✗
fwaccel offload <flow_id>
Why it's wrong here
No command exists for manually offloading a specific flow by ID. SecureXL is designed to automatically manage and offload traffic flows based on its internal templates and policy matching. Manual intervention at the individual connection level is not supported and would be infeasible in production.
- ✓
Adjusting the security policy to remove features that inhibit acceleration.
Why this is correct
The primary method to influence acceleration is to ensure that the security policy does not contain features that force traffic to the slow path. By ensuring that high-bandwidth traffic traverses a path in the policy that is acceleration-compatible, the administrator maximizes the efficiency of the gateway.
- ✗
Restarting the kernel using 'fw kernel restart'.
Why it's wrong here
Restarting the kernel is a destructive action that clears all existing connections and state tables. It does not provide any mechanism to prioritize traffic for acceleration and would cause a significant network outage, making it an entirely inappropriate action for the purpose of traffic-based performance tuning.
