NSE7 Troubleshooting and Diagnostics Practice Question
Exhibit

FGT # diagnose sys session list session info: proto=6 proto_state=01 duration=826 expire=3579 timeout=3600 flags=00000000 socktype=0 sockport=0 av_idx=0 use=3 origin-shaper= reply-shaper= per_ip_shaper= class_id=0 ha_id=0 policy_dir=0 tunnel=/ vlan_cos=0/255 state=log may_dirty npu bcm npu_flag=01 statistic(bytes/packets/err): org=1234/10/0 reply=5678/20/0 orgs:10.1.1.10/1234->20.2.2.20/80 vlan=10 reply:20.2.2.20/80->10.1.1.10/1234 vlan=10 FGT #
Based on the exhibit, what can be concluded about the session?
⚠ Common exam trap
Watch out — candidates often confuse the 'npu' state with CPU processing, assuming it means 'NPU processing by CPU' rather than recognizing it as hardware offload, leading them to select Option D incorrectly.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The session is offloaded to the NPU for hardware acceleration.
The session state 'npu' indicates that the session has been offloaded to the Network Processor Unit (NPU) for hardware acceleration. This is a normal and expected state for traffic that matches hardware-offloadable profiles, allowing the NPU to process packets at wire speed without CPU intervention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The session is a one-way session with only outbound traffic.
Why it's wrong here
The session shows both 'org' and 'reply' directions, indicating bidirectional traffic.
- ✗
The session is not being logged.
Why it's wrong here
The 'log' state flag indicates logging is enabled.
- ✓
The session is offloaded to the NPU for hardware acceleration.
Why this is correct
The 'npu' flag indicates hardware offloading to the network processor.
- ✗
The session is in the 'npu' state, meaning it is being processed by the CPU.
Why it's wrong here
The 'npu' flag means the session is offloaded to the NPU, not processed by CPU.
