A company's application on EC2 instances relies on a Single-AZ RDS for MySQL DB instance. The SysOps administrator needs to ensure failover to minimize downtime.
A SysOps administrator creates two VPCs, VPC1 and VPC2, in a company's AWS account The SysOps administrator deploys a Linux Amazon EC2 instance in VPC1 and deploys an Amazon RDS for MySQL DB instance in VPC2. The DB instance is deployed in a private subnet. An application that runs on the EC2 instance needs to connect to the database. What should the SysOps administrator do to give the EC2 instance the ability to connect to the database?
A company needs to monitor the disk utilization of Amazon Elastic Block Store (Amazon EBS) volumes The EBS volumes are attached to Amazon EC2 Linux Instances A SysOps administrator must set up an Amazon CloudWatch alarm that provides an alert when disk utilization increases to more than 80%. Which combination of steps must the SysOps administrator lake lo meet these requirements? (Select THREE.)
A company uses AWS CloudFormation to manage a stack of Amazon EC2 instances on AWS. A SysOps administrator needs to keep the instances and all of the instances' data, even if someone deletes the stack. Which solution will meet these requirements?
A SysOps administrator is optimizing the cost of a workload. The workload is running in multiple AWS Regions and is using AWS Lambda with Amazon EC2 On-Demand Instances for the compute. The overall usage is predictable. The amount of compute that is consumed in each Region varies, depending on the users' locations. Which approach should the SysOps administrator use to optimize this workload?
The SysOps administrator must dynamically reference the latest AMI ID from Systems Manager Parameter Store in CloudFormation templates for new AMI versions.
A company has an application that collects notifications from thousands of alarm systems. The notifications include alarm notifications and information notifications. The information notifications include the system arming processes, disarming processes, and sensor status. All notifications are kept as messages in an Amazon Simple Queue Service (Amazon SQS) queue. Amazon EC2 instances that are in an Auto Scaling group process the messages. A SysOps administrator needs to implement a solution that prioritizes alarm notifications over information notifications. Which solution will meet these requirements?
The SysOps administrator must modify the AWS Config rule that deletes noncompliant SSH inbound rules to update the rule to allow SSH from specific trusted IP addresses instead.
A team of developers is using several Amazon S3 buckets as centralized repositories. Users across the world upload large sets of files to these repositories. The development team's applications later process these files. A SysOps administrator sets up a new S3 bucket. DOC-EXAMPLE-BUCKET, to support a new workload. The new S3 bucket also receives regular uploads of large sets of files from users worldwide. When the new S3 bucket is put into production, the upload performance from certain geographic areas is lower than the upload performance that the existing S3 buckets provide. What should the SysOps administrator do to remediate this issue?
The SysOps administrator needs to address high disk I/O issues during EC2 instance bootstrap in an Auto Scaling group.

Question 300 - SOA-C02 discussion

Report
Export

A Sysops administrator launches an Amazon EC2 instance from a Windows Amazon Machine Image (AMI). The EC2 instance includes additional Amazon Elastic Block Store (Amazon EBS) volumes. When the instance is launched, none of the additional Amazon Elastic Block Store (Amazon EBS) volumes are initialized and ready for use through a drive letter. The SysOps administrator needs to automate the EBS volume initialization.

Which solution will meet these requirements in the MOST operationally efficient way?

Answers
D.
Add the secondary volume configuration to the DriveLetterMappingConfig.json file. Configure the InitializeDisks.ps1 Windows PowerShell script to run at launch. Create a new AMI from the running EC2 instance.
Suggested answer: D

Explanation:

To automate the initialization of additional EBS volumes on Windows EC2 instances, the most effective approach is to integrate initialization scripts within the instance so that they execute upon startup:

Configure Initialization Script: Use a Windows PowerShell script (InitializeDisks.ps1) to initialize and format the additional EBS volumes. The script can assign drive letters based on configurations specified in DriveLetterMappingConfig.json.

Automate at Launch: Ensure that the PowerShell script runs automatically upon instance startup. This can be configured through Windows Task Scheduler or by setting it up in the startup folder.

Create a Custom AMI: Once the instance is configured with the script and successfully initializes the disks on startup, create a new AMI from this setup. This AMI can then be used to launch new instances that will automatically initialize their additional EBS volumes with no manual intervention required.

This method leverages native Windows tools and AWS capabilities to automate EBS volume initialization, enhancing operational efficiency without additional external dependencies.
