Question 171

A company hosts several write-intensive applications. These applications use a MySQL database that runs on a single Amazon EC2 instance. The company asks a SysOps administrator to implement a highly available database solution that is ideal for multi-tenant workloads.
Which solution should the SysOps administrator implement to meet these requirements?
Question 172

A SysOps administrator created an AWS Cloud Formation template that provisions Amazon EC2 instances, an Elastic Load Balancer (ELB), and an Amazon RDS DB instance. During stack creation, the creation of the EC2 instances and the creation of the ELB are successful. However, the creation of the DB instance fails.
What is the default behavior of CloudFormation in this scenario?
Question 173

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?
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
Question 174

A SysOps administrator needs to automate the invocation of an AWS Lambda function. The Lambda function must run at the end of each day to generate a report on data that is stored in an Amazon S3 bucket. What is the MOST operationally efficient solution that meets these requirements?

Question 179

A SysOps administrator wants to upload a file that is 1 TB in size from on-premises to an Amazon S3 bucket using multipart uploads. What should the SysOps administrator do to meet this requirement?
Explanation:
It's a best practice to use aws s3 commands (such as aws s3 cp) for multipart uploads and downloads, because these aws s3 commands automatically perform multipart uploading and downloading based on the file size. By comparison, aws s3api commands, such as aws s3api create-multipart-upload, should be used only when aws s3 commands don't support a specific upload need, such as when the multipart upload involves multiple servers, a multipart upload is manually stopped and resumed later, or when the aws s3 command doesn't support a required request parameter.https://aws.amazon.com/premiumsupport/knowledge-center/s3-multipart-upload-cli/
Question 180

A SysOps administrator is responsible for a company's security groups. The company wants to maintain a documented trail of any changes that are made to the security groups. The SysOps administrator must receive notification whenever the security groups change.
