The AWS Solutions Architect Associate (SSA) role is one of the most sought-after certifications in cloud computing. It validates your ability to design scalable, cost-effective and secure cloud solutions on Amazon Web Services (AWS). As a Solutions Architect, your job is to plan, implement and optimize cloud architectures based on business needs. This involves choosing the right AWS services, ensuring security and keeping costs under control.
AWS Solution Architect Associate Interview QuestionsPreparing for the AWS Solutions Architect Associate (SAA) exam isn’t just about theory—it’s about applying your knowledge to real-world scenarios. Practicing commonly asked interview questions sharpens your understanding of AWS services and helps you tackle problem-solving with confidence.
In this article, we've compiled the top 100 AWS Solutions Architect questions that you should be familiar with before taking the AWS SAA exam. Additionally, we've interlinked these questions with relevant courses that dive deeper into each topic, providing you with a holistic learning experience
What to Study?
To crack the AWS Solutions Architect Associate exam, you need a strong understanding of:
- AWS Core Services (EC2, S3, RDS, VPC, IAM, Lambda)
- Architectural Best Practices (Scalability, High Availability, Fault Tolerance)
- Security & Compliance (IAM policies, Encryption, AWS Shield, WAF)
- Cost Management (AWS Pricing, Cost Explorer, Savings Plans)
AWS Solutions Architect Associate Exam Overview
The exam is designed with two distinct question formats to assess your knowledge and decision-making skills:
- Multiple Choice (Single Answer): These questions present four possible answers, with only one being correct. The remaining options serve as distractors, carefully crafted to challenge your understanding.
- Multiple Response (Multi-Select): In this format, you’ll be provided with five or more options, from which you must select two or more correct answers. The exam will specify the required number of selections but won’t confirm if you’ve chosen the right amount, adding an extra layer of complexity.
Domain 1: Design Resilient Architectures Questions
Q1. A user tries to replicate an existing EC2 instance by selecting the "Launch More Like This" option. However, the AMI linked to the original instance has been deleted. What is the outcome in this situation?
Options:
A. The instance will still launch without needing the original AMI.
B. The instance will start, but a new AMI won't be generated.
C. AWS will automatically create a new AMI and proceed with the launch.
D. An error will occur, indicating that the required AMI has been deregistered.
Explanation:
When a user tries to replicate an EC2 instance using "Launch More Like This," the process relies on the linked AMI. If the AMI is deleted or deregistered, AWS cannot launch the new instance, resulting in an error indicating the AMI is unavailable.
Answer: D
Q2. You're designing a highly scalable and reliable web application with substantial content, and you've opted to use Amazon CloudFront to accelerate the delivery of both static and dynamic content. You are aware that CloudFront integrates with Amazon CloudWatch to provide monitoring capabilities. Since you are based in Sydney, you've selected the Asia Pacific (Sydney) region in the AWS console. However, after setting up everything, you notice that no CloudFront metrics are showing up in the CloudWatch console. What could be the most probable reason for this issue?
Options:
A. CloudWatch metrics will only display if you select the same region as the web application you are monitoring.
B. CloudWatch services need to be enabled with a subscription before metrics become visible.
C. CloudFront metrics in CloudWatch are only available if you select the US East (N. Virginia) region.
D. CloudFront metrics are not yet supported in the Asia Pacific region.
Explanation:
Amazon CloudFront metrics are only available in the US East (N. Virginia) region in CloudWatch, regardless of your application's location. To view CloudFront metrics, you must select this region in the CloudWatch console; otherwise, the metrics won't appear.
Answer: C
Q3. A user needs to ensure High Availability (HA) for a PostgreSQL database. Which of the following options is the most effective solution?
Options:
A. Multi-AZ
B. Read Replica
C. Multi-region
D. PostgreSQL does not support High Availability
Explanation:
To ensure High Availability for a PostgreSQL database on AWS, Multi-AZ deployment is the best solution. It automatically creates a standby replica in another Availability Zone and switches to it if the primary instance fails, ensuring minimal downtime. Other options, like Read Replicas, improve performance but don’t provide automatic failover.
Answer: A
Q4. Your client has a large amount of sensitive data stored in Amazon S3 and is worried about the security of the data while it's being transmitted and stored. You reassure them that AWS handles encryption both in transit and at rest. However, which of the following statements is incorrect regarding server-side encryption in Amazon S3?
Options:
A. Amazon S3 server-side encryption uses strong encryption standards, including 256-bit Advanced Encryption Standard (AES-256).
B. Server-side encryption ensures that your data is encrypted while it is being transmitted over the internet.
C. With server-side encryption, Amazon S3 manages the encryption and decryption processes, including the encryption keys.
D. Server-side encryption pertains to data encryption at rest, where Amazon S3 encrypts data as it is stored on disk.
Answer: B
Explanation:
Server-side encryption in Amazon S3 is for encrypting data at rest, not during transit. Data encryption during transmission is handled by SSL/TLS. Therefore, option B is incorrect because it conflates encryption at rest with encryption in transit.
Q5. What IAM role is required for AWS Lambda to have access to a DynamoDB Stream?

Explanation:
Setting up Read Replicas in different regions is a valid approach for replicating data across multiple geographic locations. This method allows the RDS instance to asynchronously replicate data to other regions, ensuring data availability in different locations. Multi-AZ deployment, while effective for high availability within a single region, does not replicate data across regions.
Answer: B
Q9. How are EBS snapshots stored and managed in Amazon S3?
Options:
