Question #259 / 1019

A company is implementing data retention policies for their Amazon RDS databases. They need to ensure that daily automated backups are retained for exactly 2 years and can be restored when needed. Which solution meets these requirements?

A

Use AWS Backup to create a backup plan with daily backups and a retention rule set to 2 years. Assign the RDS instances to this plan.

D

Use AWS Lambda to trigger daily exports of the database to Amazon S3 and apply a bucket policy to retain objects for 2 years.

Question #392 / 1019

A company is deploying a public-facing web application on AWS. The application's frontend runs on Amazon EC2 instances, and the backend uses an Amazon RDS for PostgreSQL database. The application must be secure and accessible to global users with dynamic IP addresses. How should the security groups be configured?

A

Configure the security group for the EC2 instances to allow inbound traffic on port 443 from 0.0.0.0/0. Configure the security group for the RDS instance to allow inbound traffic on port 5432 from the security group of the EC2 instances.

B

Configure the security group for the EC2 instances to allow inbound traffic on port 443 from the customers' IP addresses. Configure the security group for the RDS instance to allow inbound traffic on port 5432 from the security group of the EC2 instances.

C

Configure the security group for the EC2 instances to allow inbound traffic on port 443 from the customers' IP addresses. Configure the security group for the RDS instance to allow inbound traffic on port 5432 from the customers' IP addresses.

D

Configure the security group for the EC2 instances to allow inbound traffic on port 443 from 0.0.0.0/0. Configure the security group for the RDS instance to allow inbound traffic on port 5432 from 0.0.0.0/0.

Sample Questions

Question #521 / 529

A company is restructuring its patching process for Amazon EC2 instances in its application account. Currently, instances are patched over the internet using a NAT gateway in the application account's VPC.

The company maintains a patch repository hosted on EC2 instances within a dedicated private VPC in a separate core account. They plan to use AWS Systems Manager Patch Manager with this repository to patch the application account's EC2 instances. The solution must ensure that EC2 instances in the application account cannot access the internet.

Additionally, these EC2 instances require connectivity to Amazon DynamoDB for application data and to Systems Manager for management tasks. They also need access to the patch repository in the core account's VPC.

Which solution meets these requirements?

A

Create a security group that denies all outbound traffic. Associate it with all EC2 instances in the application account. Establish a VPN connection between the application account's VPC and the core account's VPC. Create VPC endpoints for DynamoDB and Systems Manager. Update route tables in both accounts.

B

Deploy VPC endpoints for DynamoDB and Systems Manager. Remove the NAT gateway from the application account's VPC. Set up a VPC peering connection between the application and core accounts. Modify route tables in both VPCs to allow traffic through the peering connection.

C

Implement a network ACL blocking all outbound traffic on ports 80 and 443. Associate this NACL with the application account's subnets. Use AWS Direct Connect to establish a private connection to the core account's VPC. Create a gateway endpoint for DynamoDB.

D

Delete the NAT gateway in the application account's VPC. Create a transit gateway to connect the application and core account VPCs. Configure VPC endpoints for DynamoDB and Systems Manager. Update the route tables to route traffic through the transit gateway.

Question #52 / 529

A company hosts a web application using an Amazon API Gateway backed by AWS Lambda functions. The API Gateway is configured as the origin for an Amazon CloudFront distribution. The company uses Amazon Route 53 with an A record pointing to the CloudFront distribution. To ensure high availability and fault tolerance, which solution should be implemented?

A

Deploy a secondary Lambda function and API Gateway in another AWS Region. Update the Route 53 A record to a failover record set with both CloudFront distributions as targets, and configure health checks.

B

Deploy a secondary Lambda function and API Gateway in another AWS Region. Update the CloudFront distribution to add the new API Gateway as a second origin, then configure an origin group with primary and secondary failover settings.

C

Deploy a secondary Lambda function in another AWS Region and add it as a target to the existing API Gateway. Configure the API Gateway to use weighted routing for regional failover.

D

Deploy a secondary Lambda function and API Gateway in another AWS Region. Create a second CloudFront distribution for the new API Gateway, then use AWS Global Accelerator to route traffic to both distributions.

Question #64 / 557

A developer is migrating features from a legacy monolithic application to AWS Lambda functions. The application uses an Amazon ElastiCache Redis cluster deployed in private subnets of a VPC. The Lambda functions and the ElastiCache cluster are in the same AWS Region and account. The developer needs to ensure the Lambda functions can securely access the ElastiCache cluster without traversing the public internet.

Which solution will meet these requirements?

A

Configure the ElastiCache cluster to allow public access.

B

Set up an Amazon API Gateway between the Lambda functions and the ElastiCache cluster.

C

Configure a NAT gateway and a security group for the Lambda functions.

D

Configure the VPC, subnets, and a security group for the Lambda functions.

Question #134 / 557

A company is updating their serverless application's AWS Lambda functions using AWS CodeDeploy. The deployment must ensure that any errors are detected early without impacting all users and must complete as quickly as possible within maintenance windows. The production environment cannot tolerate downtime outside these windows.

Which deployment configuration will meet these requirements with the LEAST deployment time?

A

Use the AWS CodeDeploy in-place deployment configuration for the Lambda functions. Shift all traffic immediately after deployment.

B

Use the AWS CodeDeploy linear deployment configuration to shift 15% of the traffic every 3 minutes.

C

Use the AWS CodeDeploy all-at-once deployment configuration to shift all traffic to the updated versions immediately.

D

Use the AWS CodeDeploy predefined canary deployment configuration to shift 15% of the traffic immediately and shift the remaining traffic after 3 minutes.
