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.

Answers
D.

E.

Call AWS Systems Manager Run Command to close the port.

Answers
E.

Call AWS Systems Manager Run Command to close the port.

Suggested answer: B, D

Explanation:

To monitor and remediate open SSH ports, AWS Config and Systems Manager Automation are ideal:

AWS Config Rule: Use AWS Config to monitor security groups and detect when SSH (port 22) is open to the public. Config rules can be set up to trigger remediation actions automatically.

Systems Manager Automation Runbook: Create or use a predefined automation runbook that can remove the open SSH rule from security groups, thus closing port 22 to the public.

CloudWatch alarms are not ideal for monitoring security group configurations. Amazon Inspector focuses on vulnerability assessment rather than continuous monitoring for specific port access.
