Discuss Microsoft AB-620 Exam Topic 3 Question 3

You need to enable Operations Concierge to delegate shipment tracking inquiries according to Fabrikam Inc.'s defined architecture and technical requirements.

Which integration approach should you use?

AConfigure the primary agent to handle shipment tracking through generative responses after publishing.

BConfigure the partner capability as an enterprise knowledge source with indexed retrieval enabled.

CConfigure the partner capability as an MCP tool and invoke it as a transactional operation.

DConfigure the partner capability as an A2A integration and supply its endpoint information.

Suggested Answer: D

Comprehensive and Detailed Explanation From Microsoft AB-620 Study Guide: The partner capability is described as an agent available only through a standardized agent-to-agent endpoint. That is the defining use case for an Agent2Agent connection. In Copilot Studio, the primary agent is configured with the external agent's A2A message endpoint and the applicable authentication details, after which orchestration can delegate shipment-tracking requests to it. An MCP server exposes tools or resources rather than an independently orchestrated partner agent, so option C changes the integration contract. An indexed knowledge source is also unsuitable because shipment status is dynamic and the requirement is delegation, not retrieval from a copied corpus. Generative responses in the primary agent would have no authoritative live shipment source and would violate the defined architecture. The A2A description should identify shipment tracking precisely so that it does not compete with unrelated agents or tools. Because external-agent support can be preview functionality, Fabrikam should also validate regional availability, authentication, error behavior, latency, and governance before production use. Study Guide alignment: Integrate and extend agents in Copilot Studio > Configure multi-agent collaboration from Copilot Studio > Create a multi-agent solution by using A2A protocol.

Option A could work, but generative responses might not be reliable enough.

I prefer option C. MCP tools are great for transactions.

I think option B is the best. Indexed retrieval sounds efficient.

I’m surprised that A is even an option. Feels outdated!

Venita 1 month ago

Option C makes sense for transactional operations.

Rodolfo 2 months ago

Wait, why would we use generative responses for tracking? Sounds risky!

Malika 2 months ago

I disagree, A2A integration (option D) seems more straightforward.

Bettyann 2 months ago

I think option B is the best choice for indexed retrieval.

I’m a bit confused about the generative responses in option A. I thought those were more for conversational agents, not specifically for shipment tracking.

Ezekiel 2 months ago

I practiced a question similar to this, and I feel like option C could be the right choice since it mentions invoking a tool for operations.

Krystal 2 months ago

I'm not entirely sure, but I remember something about A2A integrations being useful for direct communication between systems. Could that be option D?

Marg 3 months ago

I think option B sounds familiar, especially with the indexed retrieval part. It might help with quick access to shipment data.
