The AWS Certified Solutions Architect – Associate (SAA-C03) exam tests your ability to design distributed systems on AWS. It is one of the most sought-after certifications in the cloud domain.
You are configuring a VPC with public and private subnets. Which component is essential for private subnet to access the internet?
AInternet Gateway
BNAT Gateway
CVPC Peering
DDirect Connect
Explanation
A NAT Gateway allows instances in a private subnet to initiate outbound traffic to the internet, while others do not provide this functionality.
Q102
A company needs to ensure that its EC2 instances can automatically scale based on CPU utilization. What should they implement?
AElastic Load Balancer
BAmazon CloudWatch
CAuto Scaling Group
DAmazon Route 53
Explanation
An Auto Scaling Group automatically adjusts instance count based on metrics like CPU utilization, while the others do not directly manage scaling.
Q103
Which service provides Object Storage in AWS?
AAmazon S3
BAmazon RDS
CAmazon EFS
DAmazon EC2
Explanation
Amazon S3 is designed specifically for object storage; RDS is for relational databases, EFS is for file storage, and EC2 is a compute service.
Q104
A company needs to protect test data from being accessed by unauthorized users. What should they implement?
AIAM roles
BVPC peering
CS3 bucket policy
DEC2 instances
Explanation
An S3 bucket policy allows fine-grained access control to protect data; IAM roles control authorization but don’t help with bucket access directly.
Q105
What happens when you launch an Amazon EC2 Instance without a security group?
AInstance cannot be launched
BInstance is launched with default rules
CNo network connectivity available
DInstance remains stopped
Explanation
If no security group is specified, the instance will be launched with the default security group rules, allowing basic traffic.
Q106
What happens to an instance in an Auto Scaling group after a scheduled scaling action is completed?
AInstance is automatically terminated
BInstance health is re-evaluated
CScheduled action is deleted
DInstance remains in stopped state
Explanation
The instance health is re-evaluated to ensure it meets the criteria.
Q107
A company needs to ensure that sensitive data in S3 cannot be accessed by unauthorized users. Which service should they use?
AAWS CloudTrail
BIAM Policies
CS3 Versioning
DAWS X-Ray
Explanation
IAM Policies control user and service access to S3 resources.
Q108
You are configuring an AWS Lambda function for image processing that requires various permissions. Which AWS service can you use to manage permissions for this function?
AAWS Secrets Manager
BAWS IAM Roles
CAWS Lambda Layers
DAWS CloudFormation
Explanation
AWS IAM Roles provide the necessary permissions for Lambda functions.
Q109
Which AWS service allows you to create virtual, scalable, and segregated compute resources in the cloud?
AEC2
BRDS
CS3
DLambda
Explanation
EC2 provides virtual servers, unlike RDS, S3, and Lambda which serve different purposes.
Q110
A customer needs to migrate a large amount of data from on-premises storage to S3. What is the fastest way to do this?
AAWS Snowball
BAWS Direct Connect
CS3 Transfer Acceleration
DCLI Tools
Explanation
AWS Snowball is designed for large data transfers efficiently, unlike Direct Connect and S3 Transfer Acceleration which serve different use cases.
