https://docs.microsoft.com/en-us/microsoftteams/teams-and-skypeforbusiness-coexistence-and-interoperabilityThe correct answer for the question is B. Skype for Business with Teams collaboration.
Explanation:
When upgrading from Skype for Business to Microsoft Teams, there are different coexistence modes available to choose from. Coexistence mode is the setting that determines how Teams and Skype for Business users can communicate with each other during the transition period.
Option A, Islands mode, is when Teams and Skype for Business users are completely separate and cannot communicate with each other. This mode is not suitable for users who still need PSTN calling with Skype for Business client.
Option C, Skype for Business only mode, is when Teams is turned off for users, and they can only use Skype for Business. This mode is not recommended if you want to evaluate Teams while maintaining PSTN calling.
Option D, Meetings First mode, is when Teams is the primary mode of communication for meetings, but users can still use Skype for Business for chat and calling. This mode is not suitable if you want to evaluate Teams for chat and persistent chat.
Therefore, the correct answer is B, Skype for Business with Teams collaboration. This mode allows users to collaborate in Teams while still using Skype for Business for PSTN calling. Users can also use both Skype for Business and Teams for chat and persistent chat. This coexistence mode is suitable for users who want to evaluate Teams while still having access to PSTN calling with Skype for Business client.
