{"question_number": 5, "question": "You are deploying Skype for Business 3PIP phones to remote sites for use with Microsoft Teams. What are two ways to sign each 3PIP phone in to Teams?", "correct_answer": "C, E", "explanation": "3PIP (third-party IP) phones support two local sign-in methods. First, a user can sign in directly on the device itself (option C) by entering credentials through the phone's own UI. Second, the phone displays a pairing code and the user completes sign-in through a web browser on any computer (option E), a flow similar to device code authentication. Remote provisioning from the Teams admin center (A) applies to native Teams IP phones, not 3PIP devices. A local user signing in from a computer that 'connects to the device' (B) is not a defined 3PIP sign-in method. Using a DID number and PIN (D) is not a supported Teams authentication path.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
