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?
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.

Export

A company is using AWS to deploy a critical application on a fleet of Amazon EC2 instances The company is rewriting the application because the application failed a security review The application will take 12 months to rewrite While this rewrite happens, the company needs to rotate IAM access keys that the application uses.

A SysOps administrator must implement an automated solution that finds and rotates IAM access Keys that are at least 30 days old. The solution must then continue to rotate the IAM access Keys every 30 days.

Which solution will meet this requirement with the MOST operational efficiency?

A.
Use an AWS Config rule to identify IAM access Keys that are at least 30 days old. Configure AWS Config to invoKe an AWS Systems Manager Automation runbook to rotate the identified IAM access keys.
Answers
A.
Use an AWS Config rule to identify IAM access Keys that are at least 30 days old. Configure AWS Config to invoKe an AWS Systems Manager Automation runbook to rotate the identified IAM access keys.
B.
Use AWS Trusted Advisor to identify IAM access Keys that are at least 30 days old. Configure Trusted Advisor to invoke an AWS Systems Manager Automation runbook to rotate the identified IAM access keys
Answers
B.
Use AWS Trusted Advisor to identify IAM access Keys that are at least 30 days old. Configure Trusted Advisor to invoke an AWS Systems Manager Automation runbook to rotate the identified IAM access keys
C.
Create a script that checks the age of IAM access Keys and rotates them if they are at least 30 days old. Launch an EC2 instance. Schedule the script to run as a cron expression on the EC2 instance every day.

C.
Create a script that checks the age of IAM access Keys and rotates them if they are at least 30 days old. Launch an EC2 instance. Schedule the script to run as a cron expression on the EC2 instance every day.
D.
Create an AWS Lambda function that checks the age of IAM access keys and rotates them if they are at least 30 days old Use an Amazon EventBridge rule to invoke the Lambda function every time a new IAM access key is created.
Answers
D.
Create an AWS Lambda function that checks the age of IAM access keys and rotates them if they are at least 30 days old Use an Amazon EventBridge rule to invoke the Lambda function every time a new IAM access key is created.
Suggested answer: D

Explanation:

Lambda Function to Rotate IAM Access Keys:

A Lambda function can be used to automate the rotation of IAM access keys based on their age.

Steps:

Write a Lambda function that checks the age of IAM access keys.

The function should rotate keys that are at least 30 days old.

Deploy the Lambda function.

Amazon EventBridge Rule:

EventBridge can trigger the Lambda function periodically and when a new key is created.

Steps:

Create an EventBridge rule that triggers the Lambda function on a schedule (e.g., daily) and on IAM key creation events.
