Cisco Jabber SIP OAuth Prerequisites
Short answer
C JSON Web Token
Question
Key Takeaways
This question tests the specific authentication protocol used by Cisco Jabber in SIP OAuth mode, with the trap being the confusion between the technical standard (JWT) and its general cryptographic property (self-contained).
Enabling SIP OAuth mode in Cisco Jabber requires replacing legacy client LSC certificates with JSON Web Tokens (JWT) for authentication. The community consensus confirms JWT as the correct answer, distinguishing it from the generic description of 'self-contained token'.
Expert Analysis
Why the Answer Is Correct
SIP OAuth mode allows Cisco Jabber to use OAuth-based authentication instead of relying on Locally Significant Certificates (LSCs). The core mechanism for this authentication involves the use of JSON Web Tokens (JWT), which carry the necessary claims and signatures for identity verification.
Why the Other Options Are Wrong
Option A is incorrect because SIP OAuth is specifically designed to eliminate the need for client LSCs. Option D describes a characteristic of JWTs but is too vague; 'self-contained token' could refer to SAML assertions or other formats, whereas JWT is the specific standard required.
Community Comment Notes
Users note that while JWTs are self-contained, option C is the precise technical term required by the exam. One comment cites official Cisco documentation stating that SIP OAuth uses 'OAuth self-describing tokens,' leading some to argue for D, but the industry standard implementation relies on JWT.

Exam Strategy
When faced with options describing a format versus its properties, always choose the specific technical standard or protocol name over the generic descriptor. In certification exams, specificity usually wins when multiple options are technically related.

Kabimas66 👍 1from: https://www.cisco.com/c/en/us/support/docs/unified-communications/jabber/215572-cisco-jabber-and-sip-oauth-mode.html#anc2 we find this (Under Key benefits) SIP OAuth mode allows Cisco Jabber Softphone to use OAuth self-describing tokens instead of client LSC certificate for authentication on secure SIP interface. So Answer is D

G0y0 👍 1 Answered Cit seems the term "self-contained" describes the Token. However the format or standard is JWT. I think it is C. the most specific.

b3532e4 👍 1Unfortunately, both C and D correct Because JSON WeB tOKEB IS A Self-contained Token
