Explanation

JWT (JSON Web Tokens) is the format Webex uses for guest tokens because JWTs are self-contained, signed tokens that can encode user identity and claims without requiring server-side session storage - making them ideal for temporary guest access in real-time collaboration platforms.

Why the distractors are wrong:

• OAuth2 (A) is an authorization framework, not a token format - it can use JWTs internally, but OAuth2 itself defines flows, not a data format.
• OAuth1 (C) is an older authorization protocol relying on request signing with shared secrets; it's largely deprecated and not a token format.
• MD5 (D) is a cryptographic hash function used for checksums/integrity checks, not for encoding identity or authorization claims.

Memory tip: Think "Just Walk Through" - guests just walk through a JWT door. JWTs have three dot-separated Base64 parts (header.payload.signature), making them easy to spot and perfect for stateless guest authentication.
