The correct action is to investigate the network devices and connectivity at Branch1. A healthScore of 10 on Cisco DNA Center’s 0–100 scale signals severe degradation, typically caused by device failures, link flaps, or complete connectivity loss, so the first troubleshooting step must be to examine the physical and logical state of the branch’s infrastructure. On the Cisco DevNet Associate 200-901 exam, this scenario tests your ability to interpret API responses and correlate low site health scores with real-world network issues, often appearing in automation and assurance questions. A common trap is jumping to re-run the script or adjust thresholds, but the core concept is that DNA Center reports symptoms, not root causes—you must dig into the devices. Memory tip: think of a health score below 20 as a red alert—always check the hardware and links first.
200-901 Understanding and Using APIs Practice Question
This 200-901 practice question tests your understanding of understanding and using apis. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Refer to the exhibit. A network engineer runs a script that queries the Cisco DNA Center site health API. The response shows Branch1 with a healthScore of 10. What is the most likely action to improve Branch1's health?
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
✓
Investigate the network devices and connectivity at Branch1.
A healthScore of 10 on a scale of 0–100 indicates severe degradation, typically caused by network device failures, link flaps, or connectivity loss. Investigating the network devices and connectivity at Branch1 is the correct first step to identify and resolve the root cause, such as a down switch or a routing issue.
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.
✓
Investigate the network devices and connectivity at Branch1.
Why this is correct
Low health score indicates problems at the site.
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.
✗
Increase the number of clients at Branch1.
Why it's wrong here
That would likely decrease health.
✗
Check the API authentication token.
Why it's wrong here
Token is valid; the API returned data.
✗
Use a different API version.
Why it's wrong here
Version is not the cause of low health.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that API response issues (like authentication or version) are the cause of low health scores, when in fact the API is correctly reporting a real network fault that must be investigated on the infrastructure side.
Detailed technical explanation
How to think about this question
Cisco DNA Center's site health API aggregates metrics from network devices (e.g., switches, routers, wireless controllers) using SNMP, NETCONF, and streaming telemetry. A healthScore of 10 typically reflects multiple critical alarms (e.g., device unreachable, high CPU, interface errors) that require immediate troubleshooting at the physical or data-link layer, such as checking LLDP neighbors or interface counters.
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 practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Drag and drop the steps to troubleshoot a network connectivity issue using the OSI model from bottom to top.
medium
Why : Troubleshooting follows the OSI model from physical up to application to systematically isolate the problem.
Variation 2. Match each YAML structure to its description.
medium
Why : YAML syntax basics.
Variation 3. Drag and drop the steps to set up a Python virtual environment for a DevNet project into the correct order.
medium
Why : Virtual environments isolate dependencies; creation, activation, package installation, and deactivation are standard steps.
