Amazon SOA-C02 Practice Test - Questions Answers, Page 47

A company migrated a non-production application that is I/O intensive to a general purpose Amazon EC2 instance. A General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume is attached to the EC2 instance. Users report that actions that require intensive reading and writing to the disk are taking longer than normal or are failing.

A SysOps administrator reviews the performance metrics of the EBS volume. The VolumeQueueLength metric is consistently high during the same times in which the users report issues. The SysOps administrator needs to resolve this problem to restore full performance to the application.

Which action will meet this requirement?

A company performs advanced statistical analysis by using custom software. The custom software runs on a cluster of Amazon EC2 instances and is sensitive to network latency between the nodes. None of the instances are approaching their network throughput limitations.

Which solution will MINIMIZE the network latency?

The SysOps administrator needs to receive email notification when the file system has less than 100 GB of space available.

Which combination of steps should the SysOps administrator take to meet this requirement? (Select TWO.)

A SysOps administrator is responsible for the performance of an AWS Lambda function. The Lambda function has a timeout of 3 seconds and has values set for provisioned concurrency and reserved concurrency.

Amazon CloudWatch metrics show that the Lambda function is experiencing several throttles each second. The metrics also show that the Lambda function's average duration is less than 100 ms.

Which solution will meet this requirement?

A SysOps administrator has many Windows Amazon EC2 instances that need to share a file system between nodes. The SysOps administrator creates an Amazon Elastic File System (Amazon EFS) file share.

Which action should the SysOps administrator take so that the EC2 instances can share the flies?

A company has a Python script that needs to send an SMS message to a monitoring center. A SysOps administrator must use Amazon EventBridge and AWS Lambda to automatically run the Python script every 60 minutes. Which solution will meet these requirements?
