A SysOps administrator has launched a large general purpose Amazon EC2 instance to regularly process large data files. The instance has an attached 1 TB General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volume. The instance also is EBS-optimized. To save costs, the SysOps administrator stops the instance each evening and restarts the instance each morning.
When data processing is active, Amazon CloudWatch metrics on the instance show a consistent 3.000 VolumeReadOps. The SysOps administrator must improve the I/O performance while ensuring data integrity.
Which action will meet these requirements?

1. A. Change the instance type to a large, burstable, general purpose instance.
2. B. Change the instance type to an extra large general purpose instance.
3. C. Increase the EBS volume to a 2 TB General Purpose SSD (gp2) volume.
4. D. Move the data that resides on the EBS volume to the instance store.

Correct Answer: C

A SysOps administrator is tasked with deploying a company's infrastructure as code. The SysOps administrator want to write a single template that can be reused for multiple environments.
How should the SysOps administrator use AWS CloudFormation to create a solution?

1. A. Use Amazon EC2 user data in a CloudFormation template
2. B. Use nested stacks to provision resources
3. C. Use parameters in a CloudFormation template
4. D. Use stack policies to provision resources

Correct Answer: C
Reuse templates to replicate stacks in multiple environments After you have your stacks and resources set up, you can reuse your templates to replicate your infrastructure in multiple environments. For example, you can create environments for development, testing, and production so that you can test changes before implementing them into production. To make templates reusable, use the parameters, mappings, and conditions sections so that you can customize your stacks when you create them. For example, for your development environments, you can specify a lower-cost instance type compared to your production environment, but all other configurations and settings remain the same. https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/best-practices.html#reuse

A manufacturing company uses an Amazon RDS DB instance to store inventory of all stock items. The company maintains several AWS Lambda functions that interact with the database to add, update, and delete items. The Lambda functions use hardcoded credentials to connect to the database.
A SysOps administrator must ensure that the database credentials are never stored in plaintext and that the password is rotated every 30 days.
Which solution will meet these requirements in the MOST operationally efficient manner?

1. A. Store the database password as an environment variable for each Lambda functio
2. B. Create a new Lambda function that is named PasswordRotat
3. C. Use Amazon EventBridge (Amazon CloudWatch Events) to schedule the PasswordRotate function every 30 days to change the database password and update the environment variable for each Lambda function.
4. D. Use AWS Key Management Service (AWS KMS) to encrypt the database password and to store the encrypted password as an environment variable for each Lambda functio
5. E. Grant each Lambda function access to the KMS key so that the database password can be decrypted when require
6. F. Create a new Lambda function that is named PasswordRotate to change the password every 30 days.
7. G. Use AWS Secrets Manager to store credentials for the databas
8. H. Create a Secrets Manager secret, and select the database so that Secrets Manager will use a Lambda function to update the database password automaticall
9. I. Specify an automatic rotation schedule of 30 day
10. J. Update each Lambda function to access the database password from SecretsManager.
11. K. Use AWS Systems Manager Parameter Store to create a secure string to store credentials for the databas
12. L. Create a new Lambda function called PasswordRotat
13. M. Use Amazon EventBridge (Amazon CloudWatch Events) to schedule the PasswordRotate function every 30 days to change the database password and to update the secret within Parameter Stor
14. N. Update each Lambda function to access the database password from Parameter Store.

Correct Answer: C
When you choose to enable rotation, Secrets Manager supports the following Amazon Relational Database Service (Amazon RDS) databases with AWS written and tested Lambda rotation function templates, and full configuration of the rotation process:
Amazon Aurora on Amazon RDS MySQL on Amazon RDS PostgreSQL on Amazon RDS Oracle on Amazon RDS MariaDB on Amazon RDS
Microsoft SQL Server on Amazon RDS https://docs.aws.amazon.com/secretsmanager/latest/userguide/intro.html
