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?

Quick Answer

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.

⚠ Common exam trap

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.

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

✓

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.

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.
✗
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.

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

✓ A.Check physical cables and interfaces, then verify data link layer, then verify network layer, then verify transport layer, then verify application layer.
B.Check application layer, then transport layer, then network layer, then data link layer, then physical layer.
C.Check physical cables and interfaces, then verify network layer, then verify transport layer, then verify application layer, skipping data link layer.
D.Check network layer first, then physical cables and interfaces, then data link layer, then transport layer, then application layer.

Why A: 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

✓ A.Mapping: An unordered set of key-value pairs, each separated by a colon and space.
✓ B.Sequence: An ordered list of items, each prefixed with a dash and space.
✓ C.Scalar: A single value, such as a string, number, or boolean, without any dash or key.
D.Mapping: An ordered list of items, each prefixed with a dash and space.
E.Sequence: An unordered set of key-value pairs, each separated by a colon and space.
F.Scalar: A collection of key-value pairs or items.

Why A: In YAML, a mapping (dictionary) uses key: value pairs; a sequence (list) uses '- ' items; a scalar is a single value. The distractors swap definitions or apply collection concepts to scalars.

Variation 3. Drag and drop the steps to set up a Python virtual environment for a DevNet project into the correct order.

medium

✓ A.Create virtual environment, Activate virtual environment, Install required packages, Deactivate virtual environment
B.Activate virtual environment, Create virtual environment, Install required packages, Deactivate virtual environment
C.Create virtual environment, Install required packages, Activate virtual environment, Deactivate virtual environment
D.Create virtual environment, Activate virtual environment, Deactivate virtual environment, Install required packages

Why A: Virtual environments isolate dependencies; creation, activation, package installation, and deactivation are standard steps.
