Question #329 / 1019

A security audit identifies that EC2 instances are missing critical operating system updates. A solutions architect must design a solution to automate vulnerability assessments and apply necessary patches across hundreds of EC2 instances. The solution must also generate compliance reports detailing each instance’s patch status. Which approach fulfills these requirements?

A

Configure Amazon Macie to perform vulnerability scans on EC2 instances. Use AWS Lambda to trigger patching via SSM documents on a recurring schedule.

B

Enable Amazon GuardDuty to detect vulnerabilities in EC2 instances. Schedule patching operations using AWS Systems Manager Maintenance Windows.

C

Implement Amazon Detective to identify vulnerabilities. Create an Amazon EventBridge rule to execute AWS Systems Manager Run Command for patching.

D

Enable Amazon Inspector to conduct vulnerability assessments. Utilize AWS Systems Manager Patch Manager to automate patching and generate compliance reports.

Question #611 / 1019

A company operates a REST-based application on Amazon EC2 instances that processes real-time data from an external provider. The provider reports frequent 503 errors during peak data transmission periods, as the EC2 instances become overwhelmed and cannot handle the request volume.

Which solution will allow the application to scale efficiently during high data traffic?

A

Ingest data using Amazon Kinesis Data Streams and process it with AWS Lambda functions.

B

Implement Amazon API Gateway with throttling limits to control the incoming request rate.

C

Use Amazon SQS to queue incoming data and process messages using EC2 instances in an Auto Scaling group.

D

Migrate the application to AWS Lambda functions with Amazon API Gateway for request handling.

Sample Questions

Question #354 / 529

A solutions architect is evaluating the high availability of an application running on Amazon EC2 instances within a private subnet of a VPC. The EC2 instances are managed by an Auto Scaling group configured with a minimum and maximum capacity of 1. The application uses an Amazon RDS for PostgreSQL DB instance. The VPC includes subnets in three Availability Zones and uses a single NAT gateway. The solutions architect must propose a solution to ensure the application operates reliably across multiple Availability Zones. Which solution meets this requirement?

A

Deploy NAT gateways in all Availability Zones. Update route tables to direct traffic through the respective NAT gateways. Modify the RDS for PostgreSQL DB instance to a Multi-AZ deployment. Reconfigure the Auto Scaling group to distribute instances across all Availability Zones. Set the Auto Scaling group's minimum and maximum capacity to 3.

B

Replace the NAT gateway with an internet gateway. Migrate the RDS for PostgreSQL DB instance to Amazon DynamoDB. Configure the Auto Scaling group to launch instances in multiple Availability Zones. Adjust the Auto Scaling group's minimum and maximum capacity to 3.

C

Deploy a NAT instance in each Availability Zone. Convert the RDS for PostgreSQL DB instance to a Single-AZ configuration. Launch additional EC2 instances manually in the remaining Availability Zones. Set the Auto Scaling group's capacity to 3.

D

Add NAT gateways in all Availability Zones. Update route tables accordingly. Enable point-in-time recovery for the RDS for PostgreSQL DB instance. Configure the Auto Scaling group to span multiple Availability Zones but retain the minimum and maximum capacity at 1.

Question #32 / 529

A company is using AWS Organizations to restrict its developers to only use Amazon RDS, AWS Lambda, and AWS CloudFormation. The developers' account is placed in a separate organizational unit (OU). The solutions architect has applied the following SCP to the developers' OU:

json { "Version": "2012-10-17", "Statement": [ { "Sid": "AllowRDS", "Effect": "Allow", "Action": "rds:*", "Resource": "*" }, { "Sid": "AllowLambda", "Effect": "Allow", "Action": "lambda:*", "Resource": "*" }, { "Sid": "AllowCloudFormation", "Effect": "Allow", "Action": "cloudformation:*", "Resource": "*" } ] } 

Despite this policy, IAM users in the developers' account can still access AWS services not listed in the SCP. What should the solutions architect do to enforce the restriction?

A. Add explicit deny statements for all AWS services except RDS, Lambda, and CloudFormation.
B. Detach the FullAWSAccess SCP from the developers' OU.
C. Update the FullAWSAccess SCP to explicitly deny all services not listed.
D. Include a wildcard deny statement at the end of the existing SCP.

A

Add explicit deny statements for all AWS services except RDS, Lambda, and CloudFormation.

B

Detach the FullAWSAccess SCP from the developers' OU.

C

Update the FullAWSAccess SCP to explicitly deny all services not listed.

D

Include a wildcard deny statement at the end of the existing SCP.

Question #355 / 557

A developer is configuring an Amazon CloudFront distribution in front of an internet-facing Application Load Balancer (ALB) serving a web application on EC2 instances. The developer needs to ensure that all data transmitted between users and the application is encrypted in transit.

Which two CloudFront settings must be configured to meet this requirement? (Choose two.)

A

Implement signed URLs for content access.

B

Set the origin protocol policy to Match Viewer.

C

Enable field-level encryption for sensitive data.

D

Configure the distribution to compress content.

E

Enforce HTTPS by redirecting HTTP traffic to HTTPS.

Question #13 / 557

A company processes payment transactions from multiple vendors through an API Gateway integrated with AWS Lambda. Each vendor submits transactions via a dedicated API. The Lambda function processes these transactions. Vendors must receive confirmation messages only for their transactions, and adding new vendors should require minimal code changes. What is the MOST scalable solution?

A

Create a separate Amazon SNS topic for each vendor. Configure the Lambda function to publish confirmations for each vendor to their respective SNS topic.

B

Create a separate Lambda function for each vendor. Configure each function to send confirmations directly to the vendor's service endpoint.

C

Create a single Amazon SNS topic. Configure the Lambda function to publish messages with vendor-specific attributes to the topic. Subscribe each vendor to the topic and apply filter policies to their subscriptions.

D

Create one Amazon SNS topic. Subscribe all vendors to the topic without any filtering.
