Question #69 / 1019

A company operates a mission-critical web application on Amazon EC2 instances behind an Application Load Balancer, with the instances in an Auto Scaling group. The application uses an Amazon RDS MySQL database deployed in a single Availability Zone. The company wants the application to be highly available with minimal downtime and minimal data loss while requiring the LEAST operational effort. Which solution meets these requirements?

A

Deploy EC2 instances across multiple AWS Regions. Use Amazon Route 53 failover routing policies. Enable cross-region read replicas for the RDS MySQL database.

B

Configure the Auto Scaling group to use multiple Availability Zones. Modify the RDS MySQL database to use a Multi-AZ deployment. Use an RDS Proxy to manage database connections.

C

Distribute EC2 instances across one Availability Zone. Create daily automated backups of the RDS database. Restore backups to a new Availability Zone during failures.

D

Deploy EC2 instances in multiple AWS Regions. Write application data to Amazon DynamoDB Global Tables. Use an Amazon CloudWatch alarm to trigger failover.

Question #472 / 1019

A real-time gaming application uses Amazon DynamoDB to store player scores. Players expect the leaderboard to update with minimal delay after each game. The development team needs an optimal solution that requires the least amount of application code changes. Which approach should they implement?

A

Configure Amazon DynamoDB Accelerator (DAX) for the scores table. Update the code to use the DAX endpoint.

B

Enable DynamoDB global tables to distribute read traffic across regions. Update the application to read from the nearest region.

C

Double the number of read capacity units for the scores table in DynamoDB. Continue to use the existing DynamoDB endpoint.

D

Deploy an Amazon ElastiCache for Memcached cluster. Update the application to query the cache before accessing DynamoDB.

Question #362 / 529

A company needs to monitor access patterns and object size distribution across Amazon S3 buckets in two AWS Regions to optimize storage costs. The company requires a centralized dashboard to visualize these metrics for the finance team. Which solution will meet these requirements with the LEAST operational overhead?

A

Deploy AWS Lambda functions in each Region to collect object size and access data. Store the data in Amazon DynamoDB and use Amazon QuickSight to build a custom dashboard with aggregated metrics for the finance team.

B

Create an Amazon EventBridge rule to capture S3 API events via AWS CloudTrail. Use a Lambda function to process the events and log metrics in Amazon CloudWatch. Build a CloudWatch dashboard to display the aggregated data.

C

Use the S3 Storage Lens default dashboard to track object size distribution and access patterns. Grant the finance team access to the dashboard directly in the S3 console.

D

Configure AWS Config rules in each Region to monitor S3 object sizes and access activity. Export the data to Amazon S3 and use Athena queries to generate reports for a custom QuickSight dashboard.

Question #97 / 529

A company is deploying a new web application on Amazon EC2 instances behind an Application Load Balancer. They want to implement AWS WAF to protect against common web exploits while ensuring legitimate users are not blocked. The solution must minimize disruption during the initial deployment phase.

How should the solutions architect configure the web ACLs to meet these requirements?

A

Set the action of the web ACL rules to Count. Enable AWS WAF logging. Analyze the requests for false positives. Modify the rules to avoid any false positive. Over time, change the action of the web ACL rules from Count to Block.

B

Use rate-based rules in the web ACLs with a high throttle limit. Temporarily block requests exceeding the limit. Define nested conditions to refine the rate-tracking scope.

C

Set the action of the web ACL rules to Block. Use AWS managed rule groups exclusively. Evaluate the rules using Amazon CloudWatch metrics and AWS WAF logs.

D

Create custom rule groups with Allow actions. Enable AWS WAF logging. Analyze requests for false positives, adjust rules, and gradually change the action from Allow to Block.

Add an --on-failure DO_NOTHING command line option to the create-stack command and the update-stack command.

B

Add a --disable-rollback command line option to the create-stack command and the update-stack command.

Question #72 / 557

A developer creates a VPC named VPC-X that has public and private subnets. The developer deploys an Amazon RDS database inside the private subnet of VPC-X. To access this database, the developer configures an AWS Lambda function in the private subnet of a different VPC, VPC-Y. When the Lambda function is executed, it fails to connect to the RDS database. What should the developer do to resolve this issue?

A

Modify the RDS security group to allow all traffic from the VPC-Y CIDR block.

B

Redeploy the Lambda function in the same VPC-X private subnet as the RDS instance and update the RDS security group to permit traffic from the Lambda function's security group.

C

Establish a VPC peering connection between VPC-X and VPC-Y, update the route tables, and configure the RDS security group to allow traffic from VPC-Y's CIDR.

D

Create an IAM policy granting RDS access and attach it to the Lambda function's execution role.
