Question #746 / 1019

A financial institution is designing a high-frequency trading system that requires ultra-low latency communication between servers. The architecture must ensure minimal network latency between Amazon EC2 instances. Which two configurations should be implemented together? (Choose two.)

A

Enable enhanced networking with SR-IOV on the EC2 instances.

B

Distribute the EC2 instances across multiple Availability Zones.

C

Launch all EC2 instances within a single cluster placement group.

D

Configure each EC2 instance with multiple elastic network interfaces.

E

Use EC2 instances that are optimized for Amazon EBS.

Question #507 / 1019

A company operates a global e-commerce platform with its inventory database hosted in a single AWS Region. The company wants to deploy the application to multiple Regions to reduce latency for users worldwide. The platform must maintain a globally consistent inventory database that supports updates from all Regions, with an average latency under 1 second for write operations. Each Regional deployment must handle local application requests independently while ensuring global data consistency.

A

Convert the database to Amazon DynamoDB and configure a global table. Use Regional endpoints in each deployment to enable low-latency writes and automatic data synchronization.

B

Migrate the database to Amazon Aurora Global Database. Configure a primary cluster in one Region and secondary clusters in other Regions. Use Regional endpoints to route writes to the primary cluster and reads to secondary clusters.

C

Migrate the database to Amazon RDS for PostgreSQL. Deploy read replicas in each Region and route write operations to the primary Region. Use read replicas for local read requests in each Region.

D

Implement Amazon ElastiCache with cluster mode enabled in each Region. Use AWS Lambda to synchronize inventory updates between Regional Redis clusters and a central RDS database.

Question #223 / 529

A social media platform is being developed using microservices architecture on Amazon ECS with AWS Fargate. The platform expects 3 million users at launch and will scale to 20 million users within 4 months. The application uses HTTPS and requires blue/green deployments. The solution must route traffic through a load balancer and automatically adjust the number of tasks based on Amazon CloudWatch alarms.

Which solution meets these requirements?

A

Configure the ECS services to use blue/green deployment with a Network Load Balancer. Request increases to the service quota for tasks per service to accommodate scaling.

B

Configure the ECS services to use blue/green deployment with a Network Load Balancer. Implement Auto Scaling groups for each service using the Cluster Autoscaler.

C

Configure the ECS services to use blue/green deployment with an Application Load Balancer. Implement Auto Scaling groups for each service using the Cluster Autoscaler.

D

Configure the ECS services to use blue/green deployment with an Application Load Balancer. Implement Service Auto Scaling for each ECS service.

Question #524 / 529

A company uses AWS Business Support and wants to monitor the cost-effectiveness of Amazon EC2 instances across multiple AWS accounts. The EC2 instances are tagged with department, environment, and project. Development EC2 instances are incurring high costs despite low utilization. The company needs to automatically identify and terminate underutilized development instances. An instance is considered underutilized if it has 15% or less average daily CPU utilization and 10 MB or less network I/O for at least 5 of the past 14 days. Which solution meets these requirements with the LEAST operational overhead?

A

Configure Amazon CloudWatch dashboards to monitor EC2 instance metrics filtered by department, environment, and project tags. Create an Amazon EventBridge rule that triggers an AWS Lambda function to terminate instances meeting the underutilization criteria.

B

Develop an AWS Lambda function that runs weekly to collect EC2 utilization metrics and store them in an Amazon RDS database. Use Amazon QuickSight to visualize the data and manually terminate underutilized development instances.

C

Use AWS Systems Manager to collect EC2 utilization data and send it to Amazon CloudWatch Logs. Create an EventBridge rule to trigger a Lambda function that filters by tags and terminates underutilized instances based on the logs.

D

Create an Amazon EventBridge rule to detect underutilized EC2 instances using AWS Trusted Advisor reports. Configure the rule to invoke an AWS Lambda function that filters instances by department, environment, and project tags and terminates qualifying development instances.
