Now the company wants to replace some of components that are running on the EC2 instances with managed AWS services that provide similar functionality. Initially, the company will transition from load balancer software that runs on EC2 instances to AWS Elastic Load Balancers. A security engineer must ensure that after this transition, all the load balancer logs are centralized and searchable for auditing. The security engineer must also ensure that metrics are generated to show which ciphers are in use. Which solution will meet these requirements?

  • ACreate an Amazon CloudWatch Logs log group. Configure the load balancers to send logs to the log group. Use the CloudWatch Logs console to search the logs. Create CloudWatch Logs filters on the logs for the required metrics.
  • BCreate an Amazon S3 bucket. Configure the load balancers to send logs to the S3 bucket. Use Amazon Athena to search the logs that are in the S3 bucket. Create Amazon CloudWatch filters on the S3 log files for the required metrics.
  • CCreate an Amazon S3 bucket. Configure the load balancers to send logs to the S3 bucket. Use Amazon Athena to search the logs that are in the S3 bucket. Create Athena queries for the required metrics. Publish the metrics to Amazon CloudWatch. (correct answer)
  • DCreate an Amazon CloudWatch Logs log group. Configure the load balancers to send logs to the log group. Use the AWS Management Console to search the logs. Create Amazon Athena queries for the required metrics. Publish the metrics to Amazon CloudWatch.
Reveal answer & explanation
Correct answer: C

The correct answer is C. Option C: Create an Amazon S3 bucket. Configure the load balancers to send logs to the S3 bucket. Use Amazon Athena to search the logs that are in the S3 bucket. Create Athena queries for the required metrics. Publish the metri...

Explanation

Amazon S3 provides durable, scalable object storage that is fully managed. A load balancer distributes traffic across targets in multiple AZs for availability and scale. Amazon Athena runs serverless SQL queries directly on data in Amazon S3 with no infrastructure to manage.

A company uses AWS Organizations to manage a multi-account AWS environment in a single AWS Region. The organization's management account is named management-01. The company has turned on AWS Config in all accounts in the organization. The company has designated an account named security-01 as the delegated administrator for AWS Config. All accounts report the compliance status of each account's rules to the AWS Config delegated administrator account by using an AWS Config aggregator. Each account administrator can configure and manage the account's own AWS Config rules to handle each account's unique compliance requirements. A security engineer needs to implement a solution to automatically deploy a set of 10 AWS Config rules to all existing and future AWS accounts in the organization. The solution must turn on AWS Config automatically during account creation. Which combination of steps will meet these requirements? (Choose two.)

  • ACreate an AWS CloudFormation template that contains the 10 required AWS Config rules. Deploy the template by using CloudFormation StackSets in the security-01 account.
  • BCreate a conformance pack that contains the 10 required AWS Config rules. Deploy the conformance pack from the security-01 account. (correct answer)
  • CCreate a conformance pack that contains the 10 required AWS Config rules. Deploy the conformance pack from the management-01 account.
  • DCreate an AWS CloudFormation template that will activate AWS Config. Deploy the template by using CloudFormation StackSets in the security-01 account.
  • ECreate an AWS CloudFormation template that will activate AWS Config. Deploy the template by using CloudFormation StackSets in the management-01 account. (correct answer)
Reveal answer & explanation
Correct answer: B, E

The correct answer is B, E. Option B: Create a conformance pack that contains the 10 required AWS Config rules. Deploy the conformance pack from the security-01 account. Option E: Create an AWS CloudFormation template that will activate AWS Config. Deploy the template by using CloudFormation StackSets in the management-01 account.

Explanation

AWS Config tracks resource configuration changes and evaluates compliance. AWS CloudFormation provisions infrastructure as code repeatably.
