INTRODUCTION
The AWS Certified Solutions Architect – Associate (SAA-C03) is an AWS certification
designed to validate technical knowledge and skills for designing secure, resilient, high-
performing, and cost-optimized solutions on AWS. AWS states that the exam is intended for
individuals performing a solutions architect role and evaluates their ability to design solutions
using the AWS Well-Architected Framework. (AWS Documentation)
The certification is particularly relevant to cloud engineers, solutions architects, developers,
systems administrators, DevOps professionals, and IT professionals who design or implement
workloads on AWS. AWS recommends approximately one year of hands-on experience
designing cloud solutions using AWS services, although it notes that candidates with less
experience can also prepare for and earn the certification. (Amazon Web Services, Inc.)
The certification can demonstrate practical knowledge of AWS architecture patterns and is useful
for professionals who need to evaluate architectural trade-offs involving security, availability,
scalability, performance, and cost. The exam emphasizes architectural decision-making rather
than deep programming or operating-system administration.
The current SAA-C03 examination contains 65 questions and provides 130 minutes. Questions
use multiple-choice and multiple-response formats. The official exam domains are Design
Secure Architectures, Design Resilient Architectures, Design High-Performing Architectures,
and Design Cost-Optimized Architectures. (Amazon Web Services, Inc.)

QUESTIONS 1-200
Q1: A company hosts a three-tier application on Amazon EC2 instances in private subnets.
The application servers need to retrieve objects from an Amazon S3 bucket, but the
company does not want traffic to traverse the public internet. Which architecture best
satisfies this requirement?
A) NAT gateway with an internet gateway
B) S3 gateway VPC endpoint with an appropriate endpoint policy
C) Internet gateway with a bucket ACL
D) Transit Gateway attached directly to S3
Correct Answer: B
Rationale: An S3 gateway VPC endpoint allows resources in a VPC to access S3 without
traversing the public internet and without requiring a NAT gateway for that traffic. A NAT
gateway would provide internet-based connectivity and introduce additional cost. An internet
gateway does not itself provide private S3 access. Transit Gateway connects VPCs and networks
but is not the mechanism for directly accessing S3.
Q2: A workload runs on EC2 instances behind an Application Load Balancer. The
instances are currently deployed in a single Availability Zone. The application must
continue operating if an Availability Zone becomes unavailable. What should the solutions
architect recommend?
,A) Increase the EC2 instance size
B) Deploy instances across multiple Availability Zones and register them with the ALB
C) Place the instances in a public subnet
D) Replace the ALB with a NAT gateway
Correct Answer: B
Rationale: Deploying application instances across multiple Availability Zones provides
redundancy against an Availability Zone failure. The Application Load Balancer can distribute
traffic among healthy instances in the available zones. Increasing instance size does not address
an Availability Zone failure. Public subnets are unnecessary for this architecture, and a NAT
gateway provides outbound connectivity rather than load balancing.
Q3: A company stores highly sensitive customer records in Amazon S3. The company
requires encryption at rest and needs the ability to control key permissions independently
from S3 permissions. Which solution should be used?
A) S3 server-side encryption with Amazon S3 managed keys
B) S3 server-side encryption with AWS KMS keys
C) Client-side compression only
D) S3 bucket versioning
Correct Answer: B
Rationale: SSE-KMS provides encryption at rest while allowing administrators to manage AWS
KMS key policies and permissions independently. S3-managed encryption keys provide
encryption but less direct control over the encryption key policy. Compression is not encryption,
and versioning protects against accidental deletion or overwrites rather than providing
encryption.
Q4: A company wants employees to access AWS accounts using their existing corporate
identities. Security administrators require centralized authentication and role-based
authorization. Which solution is most appropriate?
A) Create IAM users for every employee
B) Use AWS IAM Identity Center integrated with the corporate identity provider
C) Store employee passwords in Secrets Manager
D) Share the root account credentials
Correct Answer: B
, Rationale: IAM Identity Center can integrate with an external identity provider and provide
centralized workforce access to AWS accounts and applications. Creating individual IAM users
increases identity-management overhead. Secrets Manager is designed for securely storing
secrets, not workforce authentication. Root credentials should never be shared.
Q5: A web application experiences unpredictable traffic spikes. The application is stateless
and runs on EC2 instances. The company wants the infrastructure to automatically add
and remove instances according to demand. Which solution is most appropriate?
A) Manually launch larger EC2 instances
B) Use an EC2 Auto Scaling group behind an Application Load Balancer
C) Deploy a single EC2 instance with enhanced networking
D) Store the application on EBS snapshots
Correct Answer: B
Rationale: An Auto Scaling group can dynamically adjust the number of EC2 instances
according to demand, while an Application Load Balancer distributes requests across healthy
instances. Increasing instance size does not provide horizontal elasticity. Enhanced networking
improves network performance but does not provide automatic scaling. EBS snapshots are
storage backups, not an application scaling mechanism.
Q6: A company needs to process millions of independent image-processing jobs. Each job
can execute independently, and processing does not need to occur immediately. Which
architecture provides loose coupling and scalable workload processing?
A) One large EC2 instance with a local queue
B) Amazon SQS with worker consumers running in an Auto Scaling group
C) Amazon Route 53 health checks
D) Amazon CloudFront with Lambda@Edge
Correct Answer: B
Rationale: Amazon SQS provides durable message buffering between producers and consumers.
Worker instances can scale based on queue depth, allowing the system to process large numbers
of independent jobs while remaining loosely coupled. Route 53 performs DNS functions,
CloudFront is a content delivery service, and Lambda@Edge is intended for edge processing
rather than durable job queuing.
