CCNA AI and Network Operations Practice Question
In a REST-style API, which method is most commonly associated with retrieving information?
⚠ Common exam trap
Avoid confusing GET with other HTTP methods like POST, PUT, or DELETE, which are used for modifying resources.
Answer choices
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
✓
GET
GET is the method most commonly associated with retrieving information. In practical terms, when a client wants to read state, inventory, or configuration details from an API endpoint without modifying the resource, GET is the expected choice. This is a core automation vocabulary question and works well as an easier confidence-building item.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
GET
Why this is correct
GET is the standard HTTP method for retrieving representations of a resource without altering server state, making it the correct choice for read operations in RESTful APIs. It is both safe and idempotent, meaning multiple identical GET requests produce the same result with no side effects. Consequently, GET is the canonical method used to fetch information from an API endpoint.
- ✗
DELETE
Why it's wrong here
DELETE removes a resource from the server, failing the stem’s requirement for retrieval because it performs a destructive operation rather than a read. It tempts because DELETE is a standard HTTP verb in REST, and in scenarios where a client must remove a stored resource (e.g., deleting a user record), it is the correct choice. The axis of difference is that retrieval demands idempotent, safe methods like GET, whereas DELETE is neither safe nor idempotent in the same sense.
When this WOULD be correct
If the question were to ask which method is used to confirm the deletion of a resource, or to check if a resource exists before deletion, DELETE would be the correct answer. For example, a question might ask, 'Which method would you use to ensure a resource is removed from the server?'
- ✗
POST
Why it's wrong here
In REST, POST is the HTTP method used to submit an entity to a specified resource, often triggering side effects such as creating a subordinate resource or appending data to an existing collection. Because POST is neither safe nor idempotent, it is not designed for retrieving information without causing potential state changes on the server. Thus, while POST is a fundamental verb in RESTful APIs, it fails the stem's requirement for a read-only operation.
When this WOULD be correct
If the question were framed to ask about methods used for submitting data to a server or creating new resources, then POST would be the correct answer. For example, a question could ask which method is used to send user data to create a new account.
- ✗
PUT
Why it's wrong here
The PUT method in REST is intended to replace a target resource with the request payload, making it idempotent but explicitly a write operation. Since PUT modifies or creates a resource at a known URI, invoking it for retrieval would be semantically incorrect and could overwrite existing data if sent to the wrong endpoint. Therefore, PUT is unsuitable for reading information from an API because it performs an update or replacement rather than a safe query.
When this WOULD be correct
If the question were to ask which method is used to update or replace a resource in a RESTful API, then PUT would be the correct answer. For example, a question might state, 'Which HTTP method is used to replace an existing resource with new data?'
Option-by-option analysis
Why each answer is right or wrong
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.
✓GETCorrect answer▾
Why this is correct
GET is the standard HTTP method for retrieving representations of a resource without altering server state, making it the correct choice for read operations in RESTful APIs. It is both safe and idempotent, meaning multiple identical GET requests produce the same result with no side effects. Consequently, GET is the canonical method used to fetch information from an API endpoint.
✗DELETEWrong answer — click to see why▾
Why this is wrong here
The DELETE method is used to remove a resource from the server, not to retrieve information. Using DELETE for retrieval would violate REST principles and could lead to unintended data loss.
★ When this WOULD be the correct answer
If the question were to ask which method is used to confirm the deletion of a resource, or to check if a resource exists before deletion, DELETE would be the correct answer. For example, a question might ask, 'Which method would you use to ensure a resource is removed from the server?'
Why candidates choose this
Students might confuse DELETE with GET because both are HTTP methods, but they serve opposite purposes. The word 'delete' might be mistakenly associated with 'getting rid of' a request rather than its actual function.
✗POSTWrong answer — click to see why▾
Why this is wrong here
POST is used to create a new resource or submit data to be processed, not to retrieve information. It is not idempotent and often changes server state, making it unsuitable for simple retrieval.
★ When this WOULD be the correct answer
If the question were framed to ask about methods used for submitting data to a server or creating new resources, then POST would be the correct answer. For example, a question could ask which method is used to send user data to create a new account.
Why candidates choose this
POST is a common method in web forms and APIs, and some students might think it can be used to 'post' a request for data. However, in REST, GET is the correct method for retrieval.
✗PUTWrong answer — click to see why▾
Why this is wrong here
PUT is used to update or replace an existing resource, or create one at a specific URI. It is idempotent but modifies server state, so it is not appropriate for retrieving information.
★ When this WOULD be the correct answer
If the question were to ask which method is used to update or replace a resource in a RESTful API, then PUT would be the correct answer. For example, a question might state, 'Which HTTP method is used to replace an existing resource with new data?'
Why candidates choose this
PUT might be confused with GET because both are idempotent, but PUT is for updates, not reads. Students may think 'put' means to place a request for data, but that is incorrect.
