Agentic AI is transforming how organizations automate operations, perform reasoning, and execute actions autonomously. The following questions cover key concepts including agent architecture, governance, frameworks, automation platforms, and AI risks.
Question 1
A security team is deploying an agent that can quarantine potentially infected hosts. Which human-in-the-loop pattern is MOST appropriate?
Options
A. Notification only - the agent acts and informs the team afterward
B. Full automation - the agent acts without any human involvement
C. No agent involvement - humans should handle all security decisions manually
D. Approval required - a human must confirm before the agent quarantines a host
Correct Answer
✅ D. Approval required - a human must confirm before the agent quarantines a host
Explanation
Quarantining a host can disrupt business services and impact users. Because of the potentially significant consequences, human review should occur before the action is executed.
Human approval provides:
- Risk mitigation
- Better decision accuracy
- Reduced operational disruption
- Governance and accountability
Question 2
A network operations team needs to build an agent that monitors alerts, queries a knowledge base, and creates tickets. The team includes NOC analysts with limited Python experience, and they need the solution within a week. Which approach is MOST appropriate?
Options
A. n8n or similar low-code platform for rapid development
B. Custom C++ implementation for performance
C. Wait to hire a Python developer
D. Python with LangChain for maximum flexibility
Correct Answer
✅ A. n8n or similar low-code platform for rapid development
Explanation
The requirements emphasize:
- Rapid implementation
- Low coding complexity
- Limited Python expertise
- Workflow automation
Low-code tools such as n8n offer visual workflow designers and pre-built integrations, making them ideal for fast delivery.
Question 3
Match each ecosystem component to its role in agent architecture.
Components
- Vector Database
- Model Provider (LLM)
- Code Sandbox
- LangChain
Correct Matching
| Component | Role |
|---|---|
| Vector Database | Provides memory |
| Model Provider (LLM) | Provides the reasoning core |
| Code Sandbox | Enables safe code execution |
| LangChain | Orchestrates |
Explanation
Vector Database Stores embeddings and supports semantic retrieval, acting as long-term memory.
Model Provider (LLM) Performs reasoning, understanding, and response generation.
Code Sandbox Allows secure execution of generated code.
LangChain Coordinates interactions among models, tools, databases, and workflows.
Question 4
Which of the following BEST describes an AI agent?
Options
A. A machine learning model that generates text responses
B. A script that automates repetitive tasks based on schedules
C. An autonomous system that perceives, reasons, acts, and learns from outcomes
D. A chatbot that responds to user queries using a knowledge base
Correct Answer
✅ C. An autonomous system that perceives, reasons, acts, and learns from outcomes
Explanation
An AI agent typically:
- Perceives information
- Reasons about data
- Takes actions
- Learns from results
Unlike basic chatbots or scripts, agents pursue goals with varying degrees of autonomy.
Question 5
Which risk category is BEST described by the following scenario?
"An agent confidently recommends a network configuration change based on incorrect information it generated."
Options
A. Operational risk - cost overrun
B. Reliability risk - hallucination
C. Governance risk - unexplainability
D. Security risk - unauthorized access
Correct Answer
✅ B. Reliability risk - hallucination
Explanation
This represents an AI hallucination where the model generates incorrect information while appearing confident.
Reliability risks include:
- Hallucinations
- Incorrect recommendations
- Inaccurate outputs
- Poor decision quality
Organizations commonly reduce this risk through validation, retrieval systems, and human review.
Question 6
Which characteristic distinguishes agentic AI from generative AI like ChatGPT?
Options
A. The ability to process natural language input
B. The capacity to maintain conversation context
C. The use of large language models for reasoning
D. The capability to take autonomous actions that affect the environment
Correct Answer
✅ D. The capability to take autonomous actions that affect the environment
Explanation
Generative AI primarily creates content.
Agentic AI goes further by:
- Planning
- Making decisions
- Using tools
- Executing actions
- Pursuing goals autonomously
A useful distinction is:
Generative AI creates. Agentic AI creates and acts.
Question 7
A system receives customer support tickets, analyzes their content, creates draft responses, routes tickets to appropriate teams, monitors resolution time, and escalates overdue tickets automatically. This system is BEST classified as:
Options
A. Generative AI
B. Agentic AI
C. Reactive automation
D. Rule-based workflow
Correct Answer
✅ B. Agentic AI
Explanation
The system:
- Analyzes information
- Generates responses
- Makes routing decisions
- Monitors progress
- Escalates issues automatically
These behaviors demonstrate goal-oriented autonomy, making it an example of Agentic AI.
Question 8
Which of the following is a key advantage of n8n for building agentic workflows?
Options
A. It provides 400+ pre-built integrations and self-hosting capability
B. It offers better performance than any coded solution
C. It requires extensive Python programming knowledge
D. It must be deployed only in public cloud environments
Correct Answer
✅ A. It provides 400+ pre-built integrations and self-hosting capability
Explanation
n8n is widely adopted because it offers:
- Large integration ecosystem
- Visual workflow design
- Self-hosting support
- Fast deployment
- Low-code development
These features make it attractive for rapid AI automation projects.
Question 9
DevOps team needs to build an agent that maintains conversation state across sessions, supports human-in-the-loop interruption for approval steps, and can checkpoint and resume workflows. Which framework should they choose?
Options
A. CrewAI - for role-based team coordination
B. LangChain - for its large ecosystem
C. LangGraph - for explicit state management and checkpointing
D. AutoGen - for multi-agent conversations
Correct Answer
✅ C. LangGraph - for explicit state management and checkpointing
Explanation
LangGraph is specifically designed for:
- Stateful workflows
- Durable execution
- Human-in-the-loop operations
- Checkpointing
- Workflow recovery
- Long-running agent processes
These capabilities make it ideal for enterprise DevOps scenarios.
