200-901 Understanding and Using APIs Practice Question
This 200-901 practice question tests your understanding of understanding and using apis. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 developer calls Cisco DNA Center API to get device details and receives the JSON response shown. The device 'Switch-A' is listed but the status is 'unreachable'. Which Cisco DNA Center API endpoint was most likely used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
/dna/intent/api/v1/network-device/{id}
Option A is correct because the endpoint /dna/intent/api/v1/network-device/{id} retrieves detailed information for a specific network device, including its management IP address, reachability status, and other attributes. The JSON response showing 'Switch-A' with status 'unreachable' indicates a single-device query, which matches the path parameter {id} used to target a particular device. This endpoint returns a device-level status field (e.g., 'reachabilityStatus') that directly reflects the 'unreachable' value seen in the response.
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.
✓
/dna/intent/api/v1/network-device/{id}
Why this is correct
This endpoint retrieves a single device by ID, matching the response structure.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
/dna/intent/api/v1/site/{siteId}/device
Why it's wrong here
This endpoint returns a list of devices for a site, not a single device.
✗
/dna/intent/api/v1/device-health
Why it's wrong here
This endpoint typically returns health status like overallScore, not managementIpAddress.
✗
/dna/intent/api/v1/network-device
Why it's wrong here
This endpoint returns a list of devices, not a single device object.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between list endpoints (e.g., /network-device) and detail endpoints (e.g., /network-device/{id}), where candidates mistakenly choose the list endpoint because they see a device name in the response, but the presence of a specific status like 'unreachable' for a single device indicates the ID-specific endpoint was used.
Detailed technical explanation
How to think about this question
The Cisco DNA Center API uses a RESTful design where the /dna/intent/api/v1/network-device/{id} endpoint leverages the device's UUID (e.g., from the 'instanceUuid' field) to fetch a detailed JSON object containing fields like 'reachabilityStatus', 'managementIpAddress', and 'series'. Under the hood, this endpoint queries the DNA Center's inventory database, which stores device state from periodic SNMP polls or NETCONF sessions; an 'unreachable' status typically means the device failed to respond to ICMP or SNMP within the configured timeout (default 30 seconds). In real-world scenarios, this endpoint is critical for troubleshooting connectivity issues, as it provides the exact reason for unreachability (e.g., 'REACHABILITY_INFORMATION_NOT_AVAILABLE') and the last successful poll timestamp.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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.

What is the correct answer to this question?
The correct answer is: /dna/intent/api/v1/network-device/{id} — Option A is correct because the endpoint /dna/intent/api/v1/network-device/{id} retrieves detailed information for a specific network device, including its management IP address, reachability status, and other attributes. The JSON response showing 'Switch-A' with status 'unreachable' indicates a single-device query, which matches the path parameter {id} used to target a particular device.
