AI-102 Implement an agentic solution Practice Question
You are troubleshooting a Copilot Studio agent that uses a Power Automate flow to look up customer information from a CRM system. The flow runs successfully when tested manually, but when the agent triggers it, the flow fails with an authentication error. What is the most likely cause?
⚠ Common exam trap
Watch out — candidates often assume the flow's authentication context is always the same as the user who initiated the interaction, overlooking that Copilot Studio agents operate under their own service principal identity when triggering automated flows.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The flow uses the agent's identity instead of the user's identity, and the agent lacks CRM access.
When a Copilot Studio agent triggers a Power Automate flow, the flow runs in the context of the agent's identity (the service principal or bot registration) rather than the user who is interacting with the agent. If the flow uses the agent's identity to authenticate with the CRM system, and that identity has not been granted the necessary permissions (e.g., read/write access to customer records), the authentication will fail. Manual tests succeed because they run under the developer's or tester's identity, which already has CRM access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The flow connection was deleted after the manual test.
Why it's wrong here
If the connection were deleted, the manual test would also fail.
- ✓
The flow uses the agent's identity instead of the user's identity, and the agent lacks CRM access.
Why this is correct
Copilot Studio flows can run as the bot or the user; if configured as bot, the bot's identity may not have access.
- ✗
The user must sign in again before triggering the flow.
Why it's wrong here
The flow is triggered by the agent, not by the user signing in.
- ✗
The CRM connector requires additional permissions that were not granted.
Why it's wrong here
If the connector had insufficient permissions, the manual test would also fail.
