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 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?

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?
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 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.
The SysOps administrator needs to address high disk I/O issues during EC2 instance bootstrap in an Auto Scaling group.

Suggested answer: A, C, E

Explanation:

Create an IAM role with the CloudWatchAgentServerPolicy:

This policy grants the necessary permissions for the CloudWatch agent to collect and send metrics.

Steps:

Go to the AWS Management Console.

Navigate to IAM and create a new role.

Choose 'EC2' as the trusted entity.

Attach the 'CloudWatchAgentServerPolicy' managed policy to the role.

Attach this IAM role to your EC2 instances.

Install and start the CloudWatch agent:

The CloudWatch agent must be installed and configured to collect disk utilization metrics.

Steps:

Use AWS Systems Manager or SSH to connect to your instances.

Install the CloudWatch agent using the following commands:

sudo yum install amazon-cloudwatch-agent

sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-config-wizard

sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a fetch-config -m ec2 -c file:/path/to/your-config-file.json -s

Start the agent:

sudo systemctl start amazon-cloudwatch-agent

Configure a CloudWatch alarm:

Create an alarm based on the disk_used_percent metric.

Steps:

Go to the AWS Management Console.

Navigate to CloudWatch and select 'Alarms' from the left-hand menu.

Click on 'Create alarm.'

Select the disk_used_percent metric.

Set the threshold to 80% and configure the alarm actions (e.g., sending a notification).
