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.
A company needs to ensure high availability for its web application deployed in two AWS regions. What combination of services is recommended?
AAmazon EC2 with Route 53
BElastic Load Balancer and RDS
CCloudFront and S3
DAWS Direct Connect and VPC
Explanation
Amazon EC2 with Route 53 offers failover and high availability across regions. Other options do not ensure the same level of availability.
Q132
You are configuring a security group for an EC2 instance. What happens when you remove an inbound rule that allows traffic from a specific IP?
ATraffic from that IP is blocked
BTraffic is allowed
CIP is permanently removed
DNo impact on outgoing traffic
Explanation
Removing an inbound rule blocks traffic from that specific IP. Other options misrepresent the functionality of security groups.
Q133
Which service allows you to manage encryption keys securely?
AAWS Key Management Service (KMS)
BAWS CloudTrail
CAWS Shield
DAWS Trusted Advisor
Explanation
AWS KMS is specifically designed for managing cryptographic keys, while the others serve different purposes.
Q134
A company needs to improve application availability across multiple regions. What should they implement?
AMulti-AZ RDS
BAmazon S3
CRoute 53 with latency-based routing
DAWS Direct Connect
Explanation
Route 53's latency-based routing improves availability across regions by directing traffic to the best endpoint.
Q135
You are configuring a Lambda function with a timeout of 5 seconds. What happens if the function does not complete in time?
AIt automatically extends the timeout
BThe invocation returns an error
CThe function retries automatically
DThe function is terminated gracefully
Explanation
If a Lambda function exceeds its timeout, it fails and returns an error instead of extending or retrying.
Q136
Which service provides managed relational databases?
AAmazon RDS
BAmazon S3
CAWS Lambda
DAmazon EC2
Explanation
Amazon RDS offers managed relational database services, while the others serve different purposes.
Q137
A company needs to grant temporary access to its AWS resources for a third-party vendor. What is the best way to achieve this?
ACreate IAM user
BUse IAM roles
CEnable AWS Config
DShare root account credentials

Q138
What happens when you use the AWS CLI to set a bucket policy for S3 that denies access to everyone?
AAccess denied globally
BOnly public access denied
CBucket remains accessible
DOnly owner can access
Explanation
Setting a deny policy effectively restricts all access unless overridden, negating previous permissions.
Q139
Which AWS service is best for decoupling application components?
AAmazon SQS
BAmazon EC2
CAWS Lambda
DAmazon RDS
Explanation
Amazon SQS allows asynchronous message queuing to decouple components, while the others are primarily compute or database services.
Q140
A company needs to analyze massive sets of data quickly. Which AWS service should they use?
AAmazon RDS
BAmazon Redshift
CAmazon SES
DAmazon S3
Explanation
Amazon Redshift is a data warehouse optimized for OLAP, while the other services serve different purposes unrelated to analytics on massive datasets.
