Question #629 / 1019

A company operates a critical PostgreSQL database on Amazon RDS. To address performance improvements in newer database versions, they need to upgrade the database engine while ensuring zero data loss and minimal downtime. The solution must allow thorough testing of the upgraded database before fully switching over. Which approach meets these requirements with the LEAST operational effort?

A

Create an RDS read replica on the new PostgreSQL version. Promote the replica to a standalone instance after validation.

B

Take a manual snapshot of the database. Restore the snapshot to a new instance with the upgraded PostgreSQL version.

C

Use AWS Schema Conversion Tool (AWS SCT) to migrate the database schema and data to the upgraded PostgreSQL version.

D

Utilize Amazon RDS Blue/Green Deployments to create a synchronized staging environment for testing the upgrade before switching traffic.

Question #1007 / 1019

A healthcare analytics firm needs to process sensitive patient data collected from multiple partners. The data is stored in a relational database, and the firm must apply complex transformations before loading the results into Amazon S3. All data must be encrypted during processing using customer-specific keys, and the solution must minimize operational overhead.

Which approach meets these requirements MOST effectively?

A

Use separate AWS Glue jobs for each partner. Configure each job with server-side encryption using Amazon S3 managed keys (SSE-S3) to encrypt the output data.

B

Deploy dedicated Amazon EMR clusters for each partner. Apply client-side encryption with custom-managed keys (CSE-Custom) to encrypt data during processing.

C

Use separate AWS Glue jobs for each partner. Configure each job with client-side encryption using AWS KMS keys (CSE-KMS) to encrypt data during processing.

D

Deploy dedicated Amazon EMR clusters for each partner. Apply server-side encryption with AWS KMS keys (SSE-KMS) to encrypt the output data.

Sample Questions

Question #130 / 529

A solutions architect must evaluate a company’s Amazon EC2 instances and Amazon Elastic Block Store (EBS) volumes to optimize costs for a web application experiencing unpredictable traffic patterns. The application runs on multiple large, general-purpose EC2 instances, and the company has not identified consistent utilization trends. The architect needs to analyze the environment and implement cost-effective improvements. Which solution BEST meets these requirements?

A

Use AWS Systems Manager OpsCenter to create a dashboard visualizing Amazon CloudWatch metrics for the EC2 instances and EBS volumes. Periodically review the dashboard to identify usage trends, then manually rightsize instances based on observed peaks.

B

Enable Amazon CloudWatch detailed monitoring for the EC2 instances and EBS volumes. Build a custom dashboard to analyze metrics, manually identify patterns, and resize instances according to peak utilization metrics.

C

Install the Amazon CloudWatch agent on all EC2 instances. Activate AWS Compute Optimizer and allow it to collect data for at least 12 hours. Rightsize instances based on Compute Optimizer\u2019s automated recommendations.

D

Upgrade to the AWS Enterprise Support plan. Enable AWS Trusted Advisor and wait 12 hours for analysis. Implement Trusted Advisor\u2019s recommendations to rightsize EC2 instances.

Question #109 / 529

A large company operates a web application hosted on Amazon EC2 Linux instances in an Auto Scaling group within a private subnet. The instances are fronted by an Application Load Balancer (ALB), and AWS Systems Manager Session Manager is configured with the SSM Agent running on all instances. After a recent update to the security group rules, some instances are failing health checks and being terminated by the Auto Scaling group. The Amazon CloudWatch logs provide insufficient details to diagnose the issue. How should the solutions architect access an EC2 instance to investigate the problem?

D

Suspend the Auto Scaling group\u2019s Terminate process. Use Session Manager to connect to an unhealthy instance.

A

Suspend the Auto Scaling group\u2019s HealthCheck scaling process. Use Session Manager to connect to an unhealthy instance.

B

Enable termination protection on the instance. Use Session Manager to connect to an unhealthy instance.

C

Set the Auto Scaling group\u2019s termination policy to NewestInstance. Use Session Manager to connect to an unhealthy instance.

Sample Questions

Question #514 / 557

A developer has deployed an AWS Lambda function that is subscribed to an Amazon Simple Notification Service (Amazon SNS) topic. The developer needs to ensure that each invocation of the Lambda function is logged with its execution details in an Amazon Simple Queue Service (Amazon SQS) queue. Which solution will meet this requirement?

A

Configure the SQS queue as a dead-letter queue for the Lambda function to capture failed invocations.

B

Modify the Lambda function's code to include calls to the AWS SDK SQS SendMessage API, sending the invocation details to the SQS queue after processing each message.

C

Set up two asynchronous invocation destinations for the Lambda function: one for success events and one for failures. Assign the SQS queue as both destinations and create a CloudWatch alarm for the DestinationDeliveryFailures metric.

D

Add an asynchronous invocation destination to the Lambda function for successful executions, directing them to the SQS queue. Implement a CloudWatch alarm on the DestinationDeliveryFailures metric to monitor delivery issues.

Question #368 / 557

A developer built a distributed application using microservices deployed on Amazon EC2 instances. Due to high traffic, correlating logs across microservices for individual transactions has become challenging. The developer needs to trace request paths to identify bottlenecks.

Which two actions should the developer take to address this? (Choose two.)

A

Install the AWS X-Ray daemon on an EC2 instance, ensuring UDP port 2000 is open for outbound traffic.

B

Create a VPC endpoint for X-Ray to allow TCP traffic on port 2000 to the AWS managed daemon.

C

Integrate AWS CloudWatch Logs with X-Ray to automatically correlate log entries.

D

Incorporate the AWS X-Ray SDK into each microservice to trace and segment requests.

E

Configure Amazon Kinesis Data Firehose to stream metrics to X-Ray for analysis.
