350-401 Practice Question: Uses Cisco DNA Center API to retrieve the health…
A network engineer uses Cisco DNA Center API to retrieve the health of a device. The API call returns:
```json
{
"response": [
{
"deviceId": "1234567890",
"healthScore": 85,
"overallHealth": "good",
"memory": {
"used": 4096,
"total": 8192,
"usage": 50
},
"cpu": {
"usage": 25
}
}
]
}```
What does the healthScore of 85 indicate?
⚠ Common exam trap
350-401 often tests whether candidates can parse JSON API responses correctly; the trap is confusing a nested metric (memory.usage or cpu.usage) with the top-level healthScore.

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 device is healthy with a score of 85 out of 100.
In Cisco DNA Center's device health API, healthScore is a normalized 0–100 value where higher is better; 85 corresponds to 'good' overall health. The overallHealth field ('good') confirms the interpretation. Memory usage (50%) and CPU usage (25%) are separate metrics and are not the healthScore.
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 device is healthy with a score of 85 out of 100.
Why this is correct
The healthScore field is a normalised 0-100 metric, so 85 denotes good overall device health, corroborated by overallHealth set to good, 50 percent memory usage and 25 percent CPU usage. It is not a percentage of failed checks.
- ✗
The device is critical and needs immediate attention.
Why it's wrong here
A score of 85 with overallHealth 'good' indicates healthy operation, not a critical state requiring immediate attention. The option is tempting because low scores do signal problems, but critical status corresponds to poor health ratings, typically well below this threshold on the 0–100 scale.
- ✗
The device has 85% memory usage.
Why it's wrong here
The healthScore field is a composite 0–100 device health metric, whereas memory usage is reported separately as 50 in the memory.usage field. The option is tempting because both are percentages, but memory consumption must be read from its dedicated nested key, not the overall score.
- ✗
The device has 85% CPU usage.
Why it's wrong here
The healthScore field is a composite 0–100 device health metric, distinct from the cpu.usage field, which separately reports 25. The option is tempting because percentage-style values appear throughout the payload, but CPU utilisation is read from its own nested key, not the overall score.
