PCNSE Manage, Monitor and Operate Practice Question
This PCNSE practice question tests your understanding of manage, monitor and operate. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network engineer needs to configure SNMP traps on a PA-5250 running PAN-OS 10.2 to alert when CPU usage exceeds 80% for more than 10 minutes. Which CLI command should be used to set this threshold?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
set snmp-server trap cpu-threshold 80
Option A is correct because the CLI command 'set snmp-server trap cpu-threshold 80' directly configures the CPU utilization threshold for SNMP trap generation on a Palo Alto Networks firewall running PAN-OS 10.2. When the CPU usage exceeds 80% for a sustained period (default 10 minutes), the firewall sends an SNMP trap to configured trap destinations. This command is specific to setting the threshold value, and the 10-minute duration is a fixed, non-configurable parameter in this PAN-OS version.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
set snmp-server trap cpu-threshold 80
Why this is correct
This sets the CPU threshold for generating traps.

Read the scenario before looking for a memorised answer.
✗
show snmp-server trap
Why it's wrong here
This command only displays the current trap configuration.
✗
set snmp-server trap source-interface ethernet1/1
Why it's wrong here
This sets the source interface for traps, but does not set the threshold.
✗
set snmp-server trap destination host 192.168.1.100 community public
Why it's wrong here
This sets the trap destination but does not configure the CPU threshold.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the 'set snmp-server trap' command with subcommands for destinations or interfaces, failing to recognize that 'cpu-threshold' is a distinct parameter that must be set separately from trap receiver configuration.

Detailed technical explanation
How to think about this question
The CPU threshold trap mechanism in PAN-OS uses a fixed 10-minute averaging window to prevent flapping alerts from transient spikes; the threshold is compared against the 10-minute moving average of CPU utilization. Under the hood, the firewall's management plane monitors CPU usage via the 'cpu-monitor' process and generates an SNMPv2c trap (OID 1.3.6.1.4.1.25461.2.1.21.3.1) when the threshold is crossed. In real-world scenarios, setting this threshold too low (e.g., 50%) can cause excessive trap flooding during normal operations, while setting it too high (e.g., 95%) may delay critical alerts for resource exhaustion.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
