Question: What type of errors are reported by a Diameter node when it encounters multiple errors, according to IETF RFC 6733?
Option 1: All errors encountered
Option 2: Only protocol errors
Option 3: Only application errors
Option 4: Only the first error encountered
Explanation: According to IETF RFC 6733, when a Diameter node encounters multiple errors, it reports only the first error encountered. This is because the Diameter node includes only one Result-Code AVP or one Experimental-Result AVP in the Diameter answer.
