This 200-901 practice question tests your understanding of understanding and using apis. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 is using Cisco DNA Center API to add a new device to the inventory. Which HTTP method should be used for this operation?
PATCH
Why wrong: PATCH is for partial updates to existing resources, not creation.
GET
Why wrong: GET is used to retrieve data, not create new resources.
DELETE
Why wrong: DELETE removes resources, it does not create them.
POST
POST is the standard HTTP method to create a new resource in REST APIs.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
POST
The POST HTTP method is used to create a new resource on the server. When adding a new device to the Cisco DNA Center inventory, you are creating a new device entry, which aligns with the POST method as defined by RESTful API conventions. Cisco DNA Center's device onboarding API endpoint (e.g., /dna/intent/api/v1/network-device) specifically requires a POST request to add a device.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
PATCH
Why it's wrong here
PATCH is for partial updates to existing resources, not creation.
GET
Why it's wrong here
GET is used to retrieve data, not create new resources.
DELETE
Why it's wrong here
DELETE removes resources, it does not create them.
POST
Common exam traps
Cisco often tests the distinction between POST and PUT, where candidates mistakenly choose PUT for creation, but PUT is typically used for full replacement of an existing resource, while POST is the correct method for creating a new resource in Cisco DNA Center's API design.
Detailed technical explanation
Under the hood, Cisco DNA Center's API follows REST principles where each HTTP method maps to a CRUD operation: POST for Create, GET for Read, PATCH/PUT for Update, and DELETE for Delete. When adding a device, the API expects a POST request with a JSON payload containing device details such as IP address, SNMP credentials, and CLI transport settings. A common real-world scenario is automating device onboarding in a brownfield network, where the POST request triggers Cisco DNA Center to initiate discovery and inventory synchronization.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
