Which HTTP method is normally used by a REST API client to retrieve data from a resource without changing it?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
Distractor review
POST
POST usually creates or submits data.
Distractor review
PUT
PUT commonly replaces or updates a resource.
Best answer
GET
GET retrieves resource information.
Distractor review
DELETE
DELETE removes a resource.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Confusing HTTP methods can lead to selecting POST or PUT when the question specifically asks for retrieving data without modification. POST is often associated with creating resources, and PUT with updating them. Selecting DELETE is clearly incorrect as it removes resources. The trap is to overlook that GET is the only method designed to safely retrieve data without side effects, which is critical in REST API operations relevant to network programmability.
Technical deep dive
How to think about this question
In the context of network automation and programmability, REST APIs use HTTP methods to interact with network devices and services. The GET method is designed to retrieve data from a specified resource without causing any side effects or changes to the resource's state. This makes GET ideal for querying device configurations, status, or statistics in a safe manner. POST is primarily used to create new resources or submit data to a server, often resulting in changes. PUT replaces or updates an existing resource entirely, which can modify device configurations. DELETE removes a resource, such as deleting a configuration or object. Understanding these HTTP methods is crucial for network engineers using automation tools like Cisco DNA Center or APIs for device management, ensuring that data retrieval operations do not inadvertently alter network states or configurations.

- REST API HTTP methods
- GET method for safe data retrieval

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.
