This 200-901 practice question tests your understanding of cisco platforms and development. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer is building a Webex Teams bot that monitors network alerts from Cisco DNA Assurance. The bot must authenticate to the Webex API. Which authentication method should be used?
Basic authentication with username/password
Why wrong: Not supported for bots.
Session ID cookie
Why wrong: Not used.
OAuth2 client credentials grant with bot token
Correct method for Webex bots.
API key in query string
Why wrong: Not used.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
OAuth2 client credentials grant with bot token
Webex Teams bots require OAuth2 client credentials grant to obtain a bot token, which is a long-lived, scoped token that authenticates the bot without user interaction. This method is designed for server-to-server communication, matching the bot's need to post messages and listen for events via the Webex API. Basic authentication, session cookies, and API keys are not supported or appropriate for bot authentication in Webex.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Cisco often tests the distinction between user-based authentication (OAuth2 authorization code grant) and bot/application authentication (client credentials grant), leading candidates to mistakenly choose Basic auth or API keys due to familiarity with older APIs.
Detailed technical explanation
Under the hood, the OAuth2 client credentials grant involves the bot presenting its client ID and client secret to the Webex token endpoint (https://api.ciscospark.com/v1/access_token) to receive a bearer token. This token is then included in the Authorization header of each API request as 'Bearer <token>'. In a real-world scenario, the bot token is stored securely and refreshed as needed, and the bot uses webhooks to receive events from Cisco DNA Assurance, ensuring stateless, scalable integration.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
