Top AWS Solution Architect Interview Questions

Technical Questions

What is Amazon EC2, and how does it differ from traditional servers? Amazon EC2 (Elastic Compute Cloud) can resize compute capacity in the cloud letting companies adjust resources based on their needs. Unlike regular servers, EC2 instances are virtual, which gives them more flexibility and makes them cost-effective. To learn more about EC2 and other cloud services, check out resources like AWS Training.
Explain the concept of S3 buckets and their use cases. Amazon S3 (Simple Storage Service) is an object storage service that provides top-notch scalability, data availability, security, and performance. People use it to back up and restore data archive information, and serve static content. To see S3 in action, take a look at A Cloud Guru’s courses.
What’s the goal of Amazon VPC, and how does it operate? Amazon Virtual Private Cloud (VPC) lets you set up a separate part of the AWS cloud where you can start AWS resources in a network you create. Getting to grips with VPC is key for any AWS Solution Architect, as our Ultimate Guide to the Amazon Interview points out.
How are RDS and DynamoDB different? Amazon RDS (Relational Database Service) manages relational databases. It supports engines like MySQL PostgreSQL, and SQL Server. DynamoDB is a managed NoSQL database service. It offers performance in single-digit milliseconds no matter the scale.
What’s the process to keep data safe at rest and in transit on AWS? You can protect data at rest by using encryption tools like AWS Key Management Service (KMS). To keep data safe in transit, you can use SSL/TLS protocols. To learn more about safety best practices, check out AWS Security Fundamentals.
