200-901 Practice Question: Which TWO HTTP methods are considered safe…
Which TWO HTTP methods are considered safe according to HTTP/1.1 specification?
⚠ Common exam trap
Cisco often tests the misconception that idempotent methods (like PUT and DELETE) are also safe, but idempotence only guarantees repeated requests have the same effect, not that they are read-only.
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
According to RFC 7231, safe methods are those that do not modify the state of the resource on the server. GET and HEAD are both defined as safe because they are intended for retrieval only and must not have side effects. This means a client can make these requests without risk of altering server data.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
PUT
Why it's wrong here
PUT is not safe; it updates or replaces resources.
- ✓
GET
Why this is correct
GET is a safe method; it only retrieves resources and does not change server state.
- ✗
DELETE
Why it's wrong here
DELETE is not safe; it removes resources from the server.
- ✓
HEAD
Why this is correct
HEAD is safe; it retrieves headers identical to GET without a response body.
- ✗
POST
Why it's wrong here
POST is not safe; it often creates or modifies resources on the server.
