156-315.81.20 Performance Tuning (SecureXL/CoreXL) Practice Question
When would an administrator consider disabling SecureXL on a gateway?
⚠ Common exam trap
Candidates often suggest disabling SecureXL as a proactive performance tuning measure. It is critical to remember this is exclusively a last-resort troubleshooting step to isolate packet drops, not a standard configuration.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
To troubleshoot persistent traffic drops that cannot be explained by policy
Disabling SecureXL should only be performed as a last resort during extreme troubleshooting to isolate the cause of packet loss or system instability. It allows the administrator to verify if the acceleration layer is causing the issue. This is a rare, temporary measure; once the issue is identified, the administrator must re-enable it to restore normal performance, as the system is not intended to operate without acceleration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To increase security for encrypted traffic
Why it's wrong here
Disabling SecureXL does not enhance security. Security is provided by the firewall policy and inspection blades, not by the acceleration layer. In fact, disabling SecureXL puts more pressure on the kernel, which could lead to resource exhaustion and reduced security effectiveness during periods of high traffic load.
- ✓
To troubleshoot persistent traffic drops that cannot be explained by policy
Why this is correct
If traffic drops persist despite an correct policy, disabling SecureXL helps isolate the issue to the acceleration layer. If the drops stop when SecureXL is disabled, it indicates a defect or configuration conflict within the acceleration templates, allowing the administrator to further narrow down the source of the problem.
- ✗
To reduce the amount of logs generated
Why it's wrong here
SecureXL is an acceleration path and does not control the logging process. Disabling it would not reduce log volume; instead, it would increase the load on the firewall kernel, which might lead to more logs being generated as the kernel handles all packets individually, potentially worsening the scenario.
- ✗
When moving from a physical to a virtual gateway
Why it's wrong here
Virtual gateways, just like physical ones, benefit from SecureXL acceleration. Disabling it in a virtual environment would result in poor performance and high CPU utilization. The virtualization layer supports SecureXL, and it should remain enabled to ensure the virtual appliance performs at its expected capacity and throughput levels.
