   A network engineer is building a script that posts a daily status report to a Webex space. The script uses a personal access token stored in an environment variable. When the script runs, it receives a 401 Unauthorized response. The token was generated two weeks ago and has not expired. What is the most likely cause of the 401 response?

   • AThe token has been rate-limited due to excessive API calls.
   • BThe token was revoked because it was used from a non-browser application.
   • CThe Authorization header is missing or malformed, so the API cannot validate the token.
   • DThe Webex API requires OAuth2 client credentials instead of a personal access token for server-to-server calls.

   A chatops bot is designed to respond to commands in multiple Webex spaces. The bot uses a single webhook to receive all message events. When a user posts '!deploy' in a space, the bot must verify that the user is a moderator of that space before executing the deployment. The bot has the user's email and the room ID from the webhook. Which sequence of API calls should the bot make?

   • AGET /v1/rooms/ROOM_ID, then check the 'moderator' field.
   • BGET /v1/people?email=USER_EMAIL, then check the 'isModerator' field.
   • CPOST to /v1/memberships with the user's email to check if they are a moderator.
   • DGET /v1/memberships?roomId=ROOM_ID&personEmail=USER_EMAIL, then check the 'isModerator' field in the response.
