Oracle Cloud Platform Data Integration 2021 Specialist — Question 1

You are tasked with developing an application that requires the use of Oracle Cloud Infrastructure (OCI) APIs to POST messages to a stream in the OCI Streaming service.
Which statement is incorrect?

Answer options

• A. An HTTP 401 will be returned if the client’s clock is skewed more than 5 minutes from the server’s.
• B. The request must include an authorization signing string including (but not limited to) x-content-sha256, content-type, and content-length headers.
• C. The request does not require an Authorization header.
• D. The Content-Type header must be set to application/json

Correct answer: B

Explanation

Option B is incorrect because the request must indeed include an authorization signing string that encompasses various headers for authentication. Option A is true as a 401 error indicates a clock skew issue. Option C is also incorrect since an Authorization header is typically required for such requests, and option D is correct as the Content-Type header needs to be set to application/json for JSON payloads.
