Top 10 AWS Solutions Architect – Associate (SAA-C03) Exam / Interview Questions and Answers
✅ 1. What is the difference between an ELB (Elastic Load Balancer) and an Auto Scaling Group?
Answer:
- ELB (Elastic Load Balancer) distributes incoming application traffic across multiple targets, such as EC2 instances, in one or more availability zones.
- Auto Scaling Group (ASG) automatically adds or removes EC2 instances based on defined policies (like CPU usage).
- Key Difference: ELB balances load; ASG manages the number of instances.
Use Case: Use them together to create a scalable and highly available architecture.
✅ 2. How do you secure data at rest and in transit in AWS?
Answer:
- Data at Rest:
- Use AWS KMS for encryption.
- Enable server-side encryption (SSE) for S3, EBS, RDS, etc.
- Use customer-managed keys for more control.
- Data in Transit:
- Use SSL/TLS encryption for all data transfer.
- Enforce HTTPS using CloudFront or ALB.
Best Practice: Always encrypt sensitive data and enforce secure protocols.
✅ 3. What are the different types of storage available in AWS, and when would you use each?
Answer:
- Amazon S3: Object storage for unstructured data like backups, media, logs.
- Amazon EBS: Block storage for EC2 instances; use for databases, file systems.
- Amazon EFS: Managed NFS-based file system; ideal for shared storage across multiple EC2s.
- Amazon Glacier / S3 Glacier: Long-term archive storage; cheap but slow.
Scenario Use:
- Use S3 for static website hosting.
- Use EBS for boot volumes.
- Use EFS for shared applications.
✅ 4. What is the Well-Architected Framework, and why is it important?
Answer:
The AWS Well-Architected Framework is a set of best practices and guidelines for designing and running workloads in the AWS Cloud. It consists of six pillars:
- Operational Excellence
- Security
- Reliability
- Performance Efficiency
- Cost Optimization
- Sustainability
Importance: Ensures scalable, resilient, and efficient cloud architecture.
✅ 5. What are the different types of load balancers in AWS, and how do they differ?
Answer:
AWS offers three types of Load Balancers under Elastic Load Balancing (ELB):
- Application Load Balancer (ALB):
- Operates at Layer 7 (HTTP/HTTPS)
- Supports path-based and host-based routing
- Ideal for microservices and containers
- Network Load Balancer (NLB):
- Operates at Layer 4 (TCP/UDP)
- Extremely high performance and low latency
- Suitable for real-time applications
- Classic Load Balancer (CLB):
- Legacy option
- Supports both Layer 4 and 7
- Not recommended for new applications

✅ 6. How would you design a highly available and fault-tolerant architecture in AWS?
Answer:
Key components of a highly available architecture:
- Deploy EC2 instances in multiple Availability Zones (AZs)
- Use Auto Scaling to manage EC2 fleet size
- Use Elastic Load Balancer (ELB) to distribute traffic
- Store data in multi-AZ or cross-region services like RDS Multi-AZ or S3
- Use Route 53 for DNS failover and health checks
- Design stateless applications wherever possible
✅ 7. What are IAM Roles, and how are they different from IAM Users?
Answer:
- IAM User: Represents a single person or service with long-term credentials (username and password or access keys).
- IAM Role: Represents a temporary set of permissions that AWS services or users can assume.
Key Difference: Roles are temporary and assume-based. Users are persistent and identity-based.
Use Case: Assign a role to an EC2 instance to allow it to access S3 securely without storing credentials.

✅ 8. What is the difference between RDS and DynamoDB?
Answer:
| Feature | Amazon RDS | Amazon DynamoDB |
| Type | Relational Database | NoSQL (Key-Value and Document-based) |
| Use Case | Complex queries, joins, transactions | High-speed reads/writes, scaling |
| Management | Requires tuning and scaling | Fully managed and serverless |
| Scaling | Vertical + Read Replicas | Horizontal (auto-scaling) |
When to use:
- Use RDS for structured data and complex queries.
- Use DynamoDB for serverless, low-latency apps like gaming or IoT.
✅ 9. How can you reduce costs in AWS without sacrificing performance?
Answer:
- Use Auto Scaling to match capacity with demand.
- Choose spot instances for non-critical or batch workloads.
- Use S3 Intelligent-Tiering for storage.
- Right-size EC2 instances and database instances.
- Use Savings Plans and Reserved Instances for predictable workloads.
- Monitor with AWS Cost Explorer and Trusted Advisor.
✅ 10. What is VPC Peering, and how is it different from AWS Transit Gateway?
Answer:
- VPC Peering: Connects two VPCs for internal communication. Point-to-point connection.
- Transit Gateway: Hub-and-spoke model that connects multiple VPCs and on-prem networks through a central hub.
Key Differences:
- Scalability: Transit Gateway supports thousands of VPCs.
- Simplicity: Transit Gateway simplifies management over multiple peerings.
