Amazon Exam SOA-C02 Topic 10 Question 84 Discussion

Actual exam question for Amazon's SOA-C02 exam

Question #: 84
Topic #: 10

A company runs an application on Amazon EC2 instances. The EC2 instances are in an Auto Scaling group and run behind an Application Load Balancer (ALB). The application experiences errors when total requests exceed 100 requests per second. A SysOps administrator must collect information about total requests for a 2-week period to determine when requests exceeded this threshold.

What should the SysOps administrator do to collect this data?

AUse the ALB's RequestCount metric. Configure a time range of 2 weeks and a period of 1 minute. Examine the chart to determine peak traffic times and volumes.

BUse Amazon CloudWatch metric math to generate a sum of request counts for all the EC2 instances over a 2-week period. Sort by a 1-minute interval.

CCreate Amazon CloudWatch custom metrics on the EC2 launch configuration templates to create aggregated request metrics across all the EC2 instances.

DCreate an Amazon EventBridge (Amazon CloudWatch Events) rule. Configure an EC2 event matching pattern that creates a metric that is based on EC2 requests. Display the data in a graph.

Show Suggested Answer

Suggested Answer: A

Using the ALB's RequestCount metric will allow the SysOps administrator to collect information about total requests for a 2-week period and determine when requests exceeded the threshold of 100 requests per second. Configuring a time range of 2 weeks and a period of 1 minute will ensure that the data can be accurately examined to determine peak traffic times and volumes.

Alright, let's focus here people. I think I'm going to go with option B. The ability to drill down to a 1-minute interval is really key for identifying those peak traffic times.

Okay, yeah, I'm convinced. Option B it is. Now let's just hope the real exam question isn't even trickier than this one!
