Title: Quiz 1 — Agentic AI Foundations and the Provider Landscape
Course: AIINFRA 300: Agentic AI & the Model Context Protocol (MCP) > Section: Week 01 — Agentic AI Foundations and the Provider Landscape

Q: According to Anthropic's framing, what is the key difference between a "workflow" and an "agent"?
- Workflows never use LLMs; agents always do
- Workflows orchestrate LLMs/tools through predefined code paths; agents let the LLM dynamically direct its own process and tool use
- Agents are always faster and cheaper than workflows
- There is no meaningful difference — the terms are interchangeable
A: Workflows orchestrate LLMs/tools through predefined code paths; agents let the LLM dynamically direct its own process and tool use

Q: Anthropic recommends always building the most sophisticated, fully agentic system possible, since more agentic is always better.
- True
- False
A: False

Q: In the phrase "the user defines the what, the agent determines the how," what does the agent determine?
Feedback: Sample/expected answer: The "how" — the specific sequence of actions/steps taken to reach the goal.

Q: Which combination of factors determines how "agentic" a system is, according to this week's material?
- Model size, training data, and release date
- Goal complexity, environmental complexity, and adaptability
- Number of API calls and total token count
- Programming language and cloud provider
A: Goal complexity, environmental complexity, and adaptability

Q: Simply adding a tool (like a calculator or web search) to an LLM call is sufficient, on its own, to make that system an agent.
- True
- False
A: False

Q: As of end of 2025 / early 2026, roughly what share of the \~\$37B enterprise LLM market do Google, OpenAI, and Anthropic together control?
- Around 40%
- Around 60%
- Around 90%
- Around 25%
A: Around 90%

Q: Name the closed feedback loop that a true agent must sustain (four steps).
Feedback: Sample/expected answer: Plan, act, observe, adapt.

Q: One year after its launch, roughly how large is the MCP ecosystem in monthly SDK downloads?
- About 10,000
- About 1 million
- About 97 million+
- About 500
A: About 97 million+
