Question: In 3GPP VAE Services for 5G Systems, what is the specified content type for HTTP bodies, and how is its use signaled?
Option 1: XML, signaled by "text/xml"
Option 2: JSON, signaled by "application/xml"
Option 3: JSON, signaled by "application/json"
Option 4: CSV, signaled by "text/csv"
Explanation: In the context of 5G System's Service Based Architecture for VAE Services, using JSON (JavaScript Object Notation) as the content type for HTTP bodies ensures lightweight and easy-to-parse data interchange. Signaling its use with "application/json" content type header is crucial for correct interpretation by the receiving end, highlighting the importance of standardized communication formats in telecom networks for efficient data exchange.
