Difficulty: EasyHigh-Performing and Elastic Compute Solutions

A media company is deploying a real-time video transcoding application on a group of Amazon EC2 instances. The transcoding nodes must exchange data with minimal network latency to process video segments in parallel. The application listens on port 5000, and transcoded outputs are monitored by an internal dashboard via an Application Load Balancer (ALB). Which combination of steps should the solutions architect take to configure this environment? (Select TWO.)

  1. Deploy the EC2 instances within a cluster placement group.Answer
  2. Configure the target group health check port to use port 5000.Answer
  3. C
    Place the EC2 instances in a spread placement group to achieve maximum network throughput.
  4. D
    Configure the target group health check port to use the default HTTP port 80.
  5. E
    Mount a single Amazon EBS gp3 volume with Multi-Attach enabled across all EC2 instances to share video files.

Answer

Deploy the EC2 instances within a cluster placement group and configure the target group health check port to use port 5000.
To satisfy the low-latency network performance requirement for parallel data exchange, the solutions architect must place the EC2 instances in a cluster placement group. In addition, since the transcoding application listens on custom port 5000, the target group health check port must be updated to port 5000 so the load balancer can correctly determine instance health.

Step-by-Step Solution

1
Analyze the network latency requirement between the application nodes.
Identify that the parallel video transcoding workload requires minimal node-to-node network latency.
Determining the network latency requirements guides the selection of the correct EC2 placement group.
2
Select the appropriate EC2 placement group type.
Choose a cluster placement group to group instances close together within a single Availability Zone.
Cluster placement groups enable low-latency, high-throughput network performance between instances.
3
Analyze the load balancer health check configuration for custom ports.
Identify that the transcoding service listens on port 5000, so the target group health checks must query port 5000.
Aligning the health check port with the application port prevents the load balancer from marking healthy nodes as unhealthy.

Key Concept

Selecting the correct placement group for low latency and aligning load balancer health check ports for custom services.
