,Introduction
This comprehensive examination is designed to rigorously assess a candidate's knowledge and skills required for the
AWS Certified Solutions Architect – Associate (SAA-C03) certification. The exam focuses on validating the ability to
design, deploy, and manage secure, robust, and scalable solutions on the Amazon Web Services platform. It covers a
broad spectrum of topics, including compute, storage, networking, database, and security services, with a strong
emphasis on real-world application and architectural decision-making. Candidates will be presented with scenario-
based questions that test not only foundational theory but also applied professional knowledge, requiring critical
thinking to choose the most appropriate, cost-effective, and operationally excellent solution. This assessment is a vital
step for professionals aiming to demonstrate their proficiency in building reliable and high-performing cloud
infrastructure.
SECTION ONE: QUESTIONS 1–50
1. A company is deploying a critical web application on AWS. The application must maintain high availability across
two Availability Zones (AZs) in a single region. Which set of actions will ensure the application remains accessible if
one entire AZ fails?
A. Deploy the application on EC2 instances with Elastic IP addresses in a single AZ and create a Network Load
Balancer (NLB) to distribute traffic.
,B. Deploy the application on EC2 instances across two AZs, place them behind an Application Load Balancer (ALB),
and ensure the ALB is internet-facing.
C. Deploy the application on EC2 instances across two AZs, place them behind an Application Load Balancer (ALB)
that is configured to use a single subnet in a single AZ for its endpoints.
D. Deploy the application on EC2 instances in two AZs, place them behind an Application Load Balancer (ALB), and
ensure the ALB is configured with at least one subnet in each AZ.
🟢 Correct Answer: D. Deploy the application on EC2 instances in two AZs, place them behind an Application Load
Balancer (ALB), and ensure the ALB is configured with at least one subnet in each AZ.
🔴 Explanation: For high availability across AZs, the application must be deployed in multiple AZs. An Application
Load Balancer (ALB) can distribute traffic to targets in multiple AZs. To be highly available, the ALB itself must have
at least one subnet enabled in each AZ where it will route traffic, ensuring the load balancer node is also resilient to
an AZ failure.
2. A solutions architect is designing a system that requires a durable, scalable, and serverless database for storing
JSON documents. The data will be accessed frequently via a RESTful API. Which AWS service is the MOST suitable for
this workload?
A. Amazon RDS for MySQL
B. Amazon DynamoDB
, C. Amazon S3
D. Amazon Redshift
🟢 Correct Answer: B. Amazon DynamoDB
🔴 Explanation: Amazon DynamoDB is a fully managed, serverless, NoSQL key-value and document database that
delivers single-digit millisecond performance at any scale. It is ideal for storing JSON documents and scales
horizontally, making it perfect for serverless applications accessed via RESTful APIs. RDS is relational, S3 is object
storage, and Redshift is a data warehouse, making them less suitable for this specific use case.
3. A company has a three-tier web application running on EC2 instances in a VPC. The web tier is in public subnets,
and the application and database tiers are in private subnets. The web tier needs internet access to download
security patches. What is the most secure and cost-effective way to provide this access?
A. Assign a public Elastic IP address to each web tier EC2 instance.
B. Place the web tier instances in a public subnet and attach an Internet Gateway to the VPC.
C. Create a NAT gateway in a public subnet and route internet-bound traffic from the web tier subnets through it.
D. Deploy a NAT instance on a public subnet and configure it to route traffic.
🟢 Correct Answer: C. Create a NAT gateway in a public subnet and route internet-bound traffic from the web tier
subnets through it.
