Exam NetSec-Analyst Topic 3 Question 51 Discussion

Actual exam question for Palo Alto Networks's NetSec-Analyst exam
Question #: 51
Topic #: 3
A Palo Alto Networks firewall is reporting consistently high data plane CPU utilization (around 80-90%), but the management plane CPU remains low. Users are experiencing intermittent packet loss and application latency. You suspect a large volume of specific traffic types or signatures are consuming resources. Which of the following steps would be most effective in identifying the specific traffic causing the high data plane utilization?

Suggested Answer: C Vote an answer

High data plane CPU with low management plane CPU points to traffic processing issues. The ACC (Application Command Center) is the primary graphical interface tool for gaining immediate visibility into 'Top Applications', 'Top Threats', 'Top Users', and 'Top URLs'. This allows for quick identification of what traffic is consuming the most resources and potentially causing the high data plane CPU. Option A requires knowing the application beforehand. Option B is resource-intensive and provides raw packet data, not immediate high-level insights into resource consumption. Option D is for specific packet flow debugging. Option E is for link health, not CPU utilization by traffic.
