Additional Notes/Instructions for L2 Engineer Questions:

• Questions should be multiple-choice.
• The options should include plausible incorrect answers to test true understanding.
• Include some questions emphasizing troubleshooting procedures.
• Focus on application and networking fundamentals appropriate for an L2 level.
• Cover topics like memory, storage, power supplies, basic networking protocols, troubleshooting tools, and common network hardware.
• Provide examples involving diagrams or real-world scenarios whenever possible.
• Avoid questions requiring overly complex technical knowledge (avoid advanced networking protocols, operating system internals, or specific vendor technologies unless appropriate for L2).
