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 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 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 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.
To manage Auto Scaling group instances that have OS vulnerabilities, the SysOps administrator needs an automated patching solution.
The SysOps administrator needs to prevent launching EC2 instances without a specific tag in the application OU.

A company needs to deploy a new workload on AWS. The company must encrypt all data at rest and must rotate the encryption keys once each year. The workload uses an Amazon RDS for MySQL Multi- AZ database for data storage. Which configuration approach will meet these requirements?

A.
Enable Transparent Data Encryption (TDE) in the MySQL configuration file. Manually rotate the key every 12 months.
Answers
A.
Enable Transparent Data Encryption (TDE) in the MySQL configuration file. Manually rotate the key every 12 months.
B.
Enable RDS encryption on the database at creation time by using the AWS managed key for Amazon RDS.
Answers
B.
Enable RDS encryption on the database at creation time by using the AWS managed key for Amazon RDS.
C.
Create a new AWS Key Management Service (AWS KMS) customer managed key. Enable automatic key rotation. Enable RDS encryption on the database at creation time by using the KMS key.
Answers
C.
Create a new AWS Key Management Service (AWS KMS) customer managed key. Enable automatic key rotation. Enable RDS encryption on the database at creation time by using the KMS key.
D.
Create a new AWS Key Management Service (AWS KMS) customer managed key. Enable automatic key rotation. Enable encryption on the Amazon Elastic Block Store (Amazon EBS) volumes that are attached to the RDS DB instance.
Answers
D.
Create a new AWS Key Management Service (AWS KMS) customer managed key. Enable automatic key rotation. Enable encryption on the Amazon Elastic Block Store (Amazon EBS) volumes that are attached to the RDS DB instance.
Suggested answer: C

Explanation:

This configuration approach will meet the requirement of encrypting all data at rest and rotating the encryption keys once each year. By creating a new AWS KMS customer managed key and enabling automatic key rotation, the encryption keys will be rotated automatically every year. By enabling RDS encryption on the database at creation time using the KMS key, all data stored in the RDS for MySQL Multi-AZ database will be encrypted at rest. This approach provide more control over key management and rotation and provide additional security benefits
