Quick Answer
The answer is GET, as this HTTP method is specifically designed by a REST API client to retrieve data from a resource without causing any side effects or modifications on the server. This aligns with the principle of idempotence, meaning multiple identical GET requests will always return the same result and leave the resource unchanged, unlike POST or PUT which alter state. On the CCNA 200-301 v2 exam, this concept often appears in questions about RESTful APIs and their interaction with network devices, testing your understanding of safe versus unsafe methods. A common trap is confusing GET with POST, but remember that GET is read-only and should never be used to send data that changes server state. For a quick memory tip, think of GET as “Go and Examine the Target”—you are only looking, not touching.
This 200-301 practice question tests your understanding of ai and network operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: rEST API HTTP methods. 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.
Which HTTP method is normally used by a REST API client to retrieve data from a resource without changing it?
POST
Why wrong: POST usually creates or submits data.
PUT
Why wrong: PUT commonly replaces or updates a resource.
GET
GET retrieves resource information.
DELETE
Why wrong: DELETE removes a resource.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
GET
GET requests read a resource. They are used to retrieve state or information without modifying the target object.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
POST
Why it's wrong here
POST usually creates or submits data.
When this WOULD be correct
In a question asking which HTTP method is used to submit data to a server for processing, such as creating a new user account or submitting a form, POST would be the correct answer.
PUT
Why it's wrong here
PUT commonly replaces or updates a resource.
When this WOULD be correct
In a different question asking which HTTP method is used to update an existing resource on a server, the correct answer would be PUT. For example, a question could state, 'Which HTTP method is used to send data to a server to update an existing resource?'
GET
DELETE
Why it's wrong here
DELETE removes a resource.
Option-by-option analysis
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.
Why this is correct
GET retrieves resource information.
Why this is wrong here
POST is used to create a new resource or submit data to be processed, which typically changes the server state. It is not idempotent and should not be used for read-only operations.
★ When this WOULD be the correct answer
In a question asking which HTTP method is used to submit data to a server for processing, such as creating a new user account or submitting a form, POST would be the correct answer.
Why candidates choose this
Students may confuse POST with GET because both can send data to the server, but POST is intended for state-changing operations, not retrieval.
Why this is wrong here
PUT is used to update or replace an existing resource, which modifies the server state. It is idempotent but not intended for read-only retrieval.
★ When this WOULD be the correct answer
In a different question asking which HTTP method is used to update an existing resource on a server, the correct answer would be PUT. For example, a question could state, 'Which HTTP method is used to send data to a server to update an existing resource?'
Why candidates choose this
Students might think PUT can retrieve data because it is often used in CRUD operations alongside GET, but its purpose is to update, not retrieve.
Why this is wrong here
DELETE is used to remove a resource from the server, which is a state-changing operation. It is not suitable for retrieving data.
★ When this WOULD be the correct answer
If the question were to ask which HTTP method is used to remove a resource from a REST API, then DELETE would be the correct answer. For example, a question might state, 'Which HTTP method is used to delete a specific resource identified by a URI?'
Why candidates choose this
Students might mistakenly associate DELETE with retrieval due to its role in CRUD, but it is exclusively for deletion.

Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
REST API HTTP methods
Real-world example
A practitioner preparing for the 200-301 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. REST API HTTP methods Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
