Which statement appropriately describes performance tuning Intrusion Prevention System (IPS) functions on a Palo Alto...

Create a New Threat Profile (Answer B):

Performance tuning inIntrusion Prevention System (IPS)involves ensuring that only the most relevant and necessary signatures are enabled for the specific environment.

Palo Alto Networks allows you to createcustom threat profilesto selectively enable signatures that match the threats most likely to affect the environment. This reduces unnecessary resource usage and ensures optimal performance.

By tailoring the signature set, organizations can focus on real threats without impacting overall throughput and latency.

Why Not A:

Leaving all signatures turned on is not a best practice because it may consume excessive resources, increasing processing time and degrading firewall performance, especially in high-throughput environments.

Why Not C:

While working with TAC for debugging may help identify specific performance bottlenecks, it is not a recommended approach for routine performance tuning. Instead, proactive configuration changes, such as creating tailored threat profiles, should be made.

Why Not D:

Disabling irrelevant threat signatures can improve performance, but this task is effectively accomplished bycreating a new threat profile. Manually disabling signatures one by one is not scalable or efficient.
