AI-900 Practice Question: Describe features of generative AI workloads on Azure
What is 'multi-agent systems' in the context of Azure AI and agentic workflows?
⚠ Common exam trap
Candidates often confuse 'multi-agent' with simple scaling or distribution concepts (like load balancing or regional deployment), rather than understanding it as a collaborative architecture of specialized agents with distinct roles.

Correct answer & explanation
✓
Multiple specialised AI agents that collaborate — each with different roles — to accomplish complex goals
In Azure AI and agentic workflows, a multi-agent system involves multiple specialized AI agents, each with distinct roles (e.g., planner, coder, reviewer), that collaborate to decompose and solve complex tasks. This architecture leverages the Azure AI Agent Service to orchestrate agent communication and task delegation, enabling more robust and scalable solutions than a single monolithic model.

- ✗
Running multiple instances of the same model simultaneously for load balancing
Why it's wrong here
Scaling by running multiple instances of the same model behind a load balancer improves throughput and fault tolerance, where each request is independently handled by a replica. Multi-agent systems, in contrast, involve functionally different agents—such as planners, retrievers, and validators—that communicate and coordinate on a shared objective. Replication adds capacity but does not add role specialization or inter-agent coordination.
- ✓
Multiple specialised AI agents that collaborate — each with different roles — to accomplish complex goals
Why this is correct
A multi-agent AI system decomposes a complex goal into subtasks handled by specialized agents—for example, an orchestrator that plans, a researcher that retrieves information, a generator that drafts content, and a critic that evaluates output. These agents exchange results iteratively, enabling parallelism and higher-quality outcomes than a single monolithic prompt. This pattern is core to frameworks like Azure AI Foundry agents, which manage agent roles, tools, and communication.
- ✗
AI systems deployed across multiple Azure regions for global availability
Why it's wrong here
Deploying AI workloads across multiple Azure regions is an infrastructure strategy that provides geographic redundancy, high availability, and lower latency for users. It typically runs identical model endpoints rather than introducing distinct agents with complementary skills that interact to solve a problem. Consequently, this is about operational resilience, not the architectural collaboration of heterogeneous AI agents.
- ✗
Security agents that monitor AI systems for prompt injection and misuse
Why it's wrong here
This describes a security governance function, typically implemented as guardrails or monitoring tools, not an agent architecture for collaborative task completion. Multi-agent systems are defined by specialized AI roles that divide and coordinate a complex workflow, whereas prompt-injection monitoring is a defensive practice applied to any AI system. Therefore, equating security agents with multi-agent systems confuses oversight with the collaboration pattern itself.
