6 Storage Administrator Interview Questions and Answers

Introduction

This question assesses your fundamental knowledge of storage technologies, which is crucial for a Junior Storage Administrator role.

How to answer

• Begin by defining block storage and file storage clearly.
• Provide specific examples of technologies or use cases for each type.
• Explain the advantages and disadvantages of both storage types.
• Discuss scenarios where one might be preferred over the other.
• Ensure to relate your answer to potential use cases relevant to the company’s infrastructure.

What not to say

Example answer

“Block storage refers to storing data in fixed-size blocks, making it ideal for applications requiring high performance, such as databases. For instance, systems like AWS EBS (Elastic Block Store) are commonly used for this purpose. On the other hand, file storage organizes data in a hierarchical structure, which is useful for unstructured data, such as documents and multimedia files, often seen in systems like NFS (Network File System). Each has its place; I would use block storage for performance-sensitive applications and file storage for collaborative environments like shared drives.”
