Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
JSON over HTTPS REST API
Why it's wrong here
eStreamer is a legacy binary streaming protocol, not a standard JSON REST API.

Why it's wrong here
eStreamer does not use SOAP/XML.
