EBS (Elastic Block Store)
EBS (Elastic Block Store) is Amazon's cloud storage system that works like a virtual hard drive for cloud computers. Think of it as a digital filing cabinet that companies can easily expand or shrink based on their needs. It's particularly important because it safely stores data even when cloud computers are turned off, similar to how your computer's hard drive keeps files when you shut down. When you see EBS mentioned in a resume, it usually means the person has experience managing cloud storage and keeping business data safe and accessible in Amazon's cloud platform (AWS).

Example Interview Questions
Senior Level Questions
Q: How would you design a cost-effective storage solution using EBS for a large enterprise?
Expected Answer: A strong answer should discuss choosing appropriate volume types based on needs, implementing automated snapshot strategies, and optimizing costs through proper volume sizing and cleanup of unused resources.
Q: Explain your approach to EBS disaster recovery planning.
Expected Answer: Should discuss creating regular snapshots, cross-region backup strategies, testing recovery procedures, and maintaining business continuity during potential failures.
Mid Level Questions
Q: What are the different EBS volume types and when would you use each?
Expected Answer: Should explain the basic differences between standard, SSD, and specialized volumes in simple terms, and when each is most cost-effective for different business needs.
Q: How do you monitor EBS performance and resolve common issues?
Expected Answer: Should describe basic monitoring practices, common performance problems, and simple troubleshooting steps used to resolve storage issues.
Junior Level Questions
Q: What is an EBS snapshot and why is it important?
Expected Answer: Should be able to explain that snapshots are backup copies of EBS volumes and why they're important for data protection and recovery.
Q: How do you create and attach an EBS volume to an instance?
Expected Answer: Should demonstrate basic knowledge of creating storage volumes and connecting them to cloud servers using AWS tools.
