What happens when you set EC2 instance termination protection to 'enabled'?
AInstance can’t be started
BInstance can’t be stopped
CInstance can’t be terminated
DInstance becomes more expensive
Explanation
Termination protection prevents accidental deletions, while it does not hinder starting or stopping the instance.
Q202
Which service enables automated server management in AWS?
AAWS OpsWorks
BAmazon S3
CAWS Config
DAWS Lambda
Explanation
AWS OpsWorks is designed for configuration management, while others serve different purposes like storage, compliance, or compute.
Q203
A company needs a solution to regularly back up its RDS databases. Which service should they use?
AAWS Backup
BAmazon S3
CAWS CloudFormation
DAmazon EC2
Explanation
AWS Backup is specifically designed for automating backups across services, while others do not provide backup capabilities.
Q204
What happens when you configure an IAM policy with a non-existent resource ARN?
AAccess is denied
BPolicy is ignored
CAccess is granted
DError generated during request
Explanation
AWS IAM will deny access when referencing an invalid resource, protecting against unintended access.
Q205
Which service provides monitoring and observability for AWS resources?
AAmazon CloudWatch
BAWS Inspector
CAWS Trusted Advisor
DAWS Config
Explanation
Amazon CloudWatch monitors resources, while others focus on security or compliance.
Q206
A company needs to secure sensitive data stored in S3. What is the best practice for encrypting this data at rest?
AUse SSE-S3 encryption
BRely on bucket policies only
CEncrypt data in transit only
DUse IAM roles for access management
Explanation
SSE-S3 provides server-side encryption; policies alone do not encrypt data.
Q207
You are configuring a Lambda function to run based on events from an S3 bucket. What happens if the function fails to process an event?
AEvent is deleted instantly
BEvent is retried based on Lambda settings
CThe Lambda function auto-scales
DNo action is taken
Explanation
Lambda automatically retries failed events, while the other options are incorrect responses to failures.
Q208
Which service is best for serverless compute?
AAWS Lambda
BAmazon EC2
CAmazon Lightsail
DAmazon ECS
Explanation
AWS Lambda allows you to run code without provisioning servers, unlike the other options, which require server management.
Q209
A company needs to allow its development team access to some AWS resources while restricting access to production resources. How can this be achieved?
AUse IAM groups and roles.
BUtilize CloudFormation templates.
CCreate VPC peering connections.
DUse AWS Single Sign-On.
Explanation
Using IAM groups and roles allows granular access control over specific resources, whereas the other options do not directly address permissions management.
Q210
What happens when you terminate an EC2 instance in a non-persistent storage setting?
AData in instance store is saved.
BData is lost when terminated.
CInstance automatically restarts.
DData is replicated to S3.
Explanation
In non-persistent (instance store) configurations, data is lost upon termination, whereas other options do not accurately describe EC2 behavior.
