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.
Which service is used for serverless computing on AWS?
AAWS Lambda
BAmazon EC2
CAmazon RDS
DAWS Elastic Beanstalk
Explanation
AWS Lambda allows running code without provisioning servers, unlike EC2 or RDS which require server management.
Q92
A company needs to distribute web traffic to multiple instances efficiently. Which AWS service should they use?
AAmazon Route 53
BAWS CloudFormation
CAWS Elastic Load Balancing
DAmazon S3
Explanation
AWS Elastic Load Balancing distributes traffic across multiple instances, whereas S3 is for storage and CloudFormation is for orchestration.
Q93
You are configuring an IAM policy to allow list access to all S3 buckets. What happens if you don't specify a resource?
AAccess denied by default
BAccess granted to all buckets
COnly default buckets accessible
DPolicy gets ignored
Explanation
Without specifying a resource in IAM, neither Deny nor Allow policies apply, resulting in access being denied by default.
Q94
Which service provides serverless compute for containers?
AAWS Lambda
BAmazon ECS
CAWS Fargate
DAmazon EC2
Explanation
AWS Fargate allows you to run containers without managing servers, unlike the others.
Q95
A company needs to securely share S3 objects but only with specific users in their organization. Which S3 feature should they use?
ABucket Policies
BACLs
CS3 Object Lock
DIAM Roles
Explanation
Bucket Policies can restrict access for specific IAM users, whereas the others don't limit access as needed.
Q96
What is the effect of a security group set to deny all inbound traffic?
AEC2 instances cannot communicate outside
BAny outbound traffic is blocked
CNo inbound traffic is allowed
DInstances cannot connect to the internet
Explanation
A security group can deny inbound traffic, which affects incoming connections, unlike the other persisting connections or outbound traffic.
Q97
Which service provides event-driven serverless computing?
AAWS Lambda
BEC2
CECS
DElastic Beanstalk
Explanation
AWS Lambda allows you to run code without provisioning servers; EC2, ECS, and Elastic Beanstalk require server management.
Q98
A company needs to store large amounts of unstructured data. Which service should they use?
AAmazon RDS
BAmazon S3
CAmazon DynamoDB
DAmazon EFS
Explanation
Amazon S3 is designed for unstructured data storage, whereas RDS and DynamoDB cater to structured data and EFS is a file system service.
Q99
What happens when an IAM user exceeds the maximum number of allowed access keys?
ANew access key goes into a queue
BThey can't create new access keys
COld access keys are deleted automatically
DAccess keys become invalid
Explanation
An IAM user can only have two active access keys, and cannot create more until one is deleted; no key management happens automatically.
Q100
Which service is primarily used for serverless computing?
AAWS Lambda
BAmazon EC2
CAWS Elastic Beanstalk
DAmazon RDS
Explanation
AWS Lambda allows for running code without provisioning servers, while the others are not serverless solutions.
