You Have an Auto Sealing Group of Instances That Processes

question 579

Multiple Choice

You have an Auto Sealing group of Instances that processes messages from an Amazon Simple Queue Service (SQS) queue. The group scales on the size of the queue. Processing Involves calling a third-party web service. The web service is complaining about the number of failed and repeated calls it is receiving from you. You have noticed that when the group scales in, instances are being terminated while they are processing. What cost-effective solution can you use to reduce the number of incomplete process attempts?

• A) Create a new Auto Scaling group with minimum and maximum of 2 and instances running web proxy software. Configure the VPC route table to route HTTP traffic to these web proxies.
• B) Modify the application running on the instances to enable termination protection while it processes a task and disable it when the processing is complete.
• C) Increase the minimum and maximum size for the Auto Scaling group, and change the scaling policies so they scale less dynamically.
• D) Modify the application running on the instances to put itself into an Auto Scaling Standby state while it processes a task and return itself to InService when the processing is complete.
