Question #639 / 1019

A gaming platform is experiencing performance issues due to uneven traffic distribution across its backend servers. The platform uses an Application Load Balancer (ALB) to route traffic to Amazon EC2 instances deployed in multiple Availability Zones within a VPC. Monitoring shows that one EC2 instance is handling a disproportionate share of requests, leading to increased latency. What should the solutions architect recommend to address this issue?

A

Disable session affinity (sticky sessions) on the ALB

B

Replace the ALB with a Gateway Load Balancer

C

Increase the number of EC2 instances in each Availability Zone

D

Modify the health check thresholds on the ALB's target group

Question #662 / 1019

A company uses AWS Cost Explorer and observes a consistent monthly increase in Amazon EBS snapshot costs, even though no new EBS volumes are added. The company seeks to minimize these costs with the LEAST operational effort. Which solution should they implement?

A

Manually identify and delete outdated snapshots. Implement a script to automate future snapshot deletions.

B

Use Amazon CloudWatch alarms to monitor snapshot counts. Manually delete snapshots when alarms trigger.

C

Delete all snapshots older than 30 days. Schedule daily snapshots with a custom script.

D

Remove unnecessary snapshots and configure Amazon Data Lifecycle Manager to automate snapshot retention policies.

Question #189 / 529

A company is enhancing an e-commerce platform hosted on Amazon ECS with DynamoDB. They've faced increased DDoS attacks and need to ensure minimal downtime during attacks cost-effectively. The setup includes a public ALB for user access.

Which two steps should they take?

A

Set up CloudFront with the ALB as origin, using a custom origin header. Configure ALB to allow traffic only with that header.

B

Deploy the application across multiple AWS Regions with Route 53 failover routing.

C

Implement ElastiCache for DynamoDB to handle increased read traffic.

D

Enable AWS Shield Advanced for DDoS protection.

E

Associate an AWS WAF web ACL with the CloudFront distribution, using managed rule groups.

Question #209 / 529

A company operates an IoT platform on AWS, utilizing millions of sensors across Europe that transmit data via MQTT to a custom broker hosted on an EC2 instance. The broker's domain is mqtt.example.net, managed by Route 53. Data is stored in Amazon S3. Recent data surges have caused broker overloads, leading to data loss. The company needs a more reliable solution.

Which solution meets these requirements?

A

Deploy an Application Load Balancer and Auto Scaling group for the broker. Update Route 53 with an alias to the ALB. Continue using the broker for storage.

B

Migrate to AWS IoT Core, set up a custom domain, update Route 53 to point to IoT Core's ATS endpoint, and use IoT rules to store data in S3.

C

Use a Network Load Balancer with the broker as target, create a Global Accelerator pointing to NLB, update Route 53 with multivalue records pointing to Accelerator IPs.

D

Implement AWS IoT Greengrass, update DNS to Greengrass endpoint, and use IoT rules to trigger Lambda for storage.
