Actual exam question for Amazon's SOA-C02 exam

Question #: 105
Topic #: 10

A SysOps administrator is investigating a company's web application for performance problems The application runs on Amazon EC2 instances that are in an Auto Scaling group. The application receives large traffic increases at random times throughout the day. During periods of rapid traffic increases, the Auto Scaling group is not adding capacity fast enough. As a result, users are experiencing poor performance.

The company wants to minimize costs without adversely affecting the user experience when web traffic surges quickly. The company needs a solution that adds more capacity to me Auto Scaling group for larger traffic increases than for smaller traffic increases.

How should the SysOps administrator configure the Auto Scaling group to meet these requirements?

ACreate a simple scaling policy with settings to make larger adjustments in capacity when the system is under heavy load

BCreate a step scaling policy with settings to make larger adjustments in capacity when the system is under heavy load.

CCreate a target tracking scaling policy with settings to make larger adjustments in capacity when the system is under heavy load

DUse Amazon EC2 Auto Scaling lifecycle hooks Adjust the Auto Scaling group's maximum number of instances after every scaling event

Show Suggested Answer

Suggested Answer: A

Increasing DB Instance Size:

Increasing the instance size provides more CPU and memory resources, which can help handle higher loads.

Steps:

Go to the AWS Management Console.

Navigate to RDS and select the DB instance.

Modify the instance to increase its size.

Apply the changes during the next maintenance window or immediately if it is a critical issue.

Monitoring Performance:

After resizing, monitor the instance during the next report run to ensure that it handles the load effectively.

Wait, so we're not just going to throw a bunch of EC2 instances at the problem and hope for the best? This is way more nuanced than I expected. I'm impressed, SysOps admins have a tough job!

That makes sense, it will add more capacity during larger traffic increases and less during smaller ones.

Use target tracking scaling policies to automatically adjust the capacity of the Auto Scaling group based on demand.

I can already hear the CFO groaning about the costs if we just crank up the capacity whenever the load gets heavy. B seems like the best balance between performance and cost savings.

B: Yes, that could be a good option to automatically adjust capacity based on traffic.

D sounds a bit convoluted, adjusting the max instances after each scaling event seems like it could get messy. I think I'll stick with the more straightforward options like B or C.

True, C could also work. It's a target tracking scaling policy which might be more efficient.

But what about C? It also allows for larger adjustments in capacity during heavy load.

I'm leaning towards C, the target tracking scaling policy seems like it could automatically scale up the capacity when the system is under heavy load. That could be a good hands-off solution.

Option B looks promising, the step scaling policy could help adjust capacity based on the load. I'll need to do some research on how to configure that properly.
