A company is implementing new compliance requirements to meet customer needs. According to the new requirements the company must not use any Amazon RDS DB instances or DB clusters that lack encryption of the underlying storage. The company needs a solution that will generate an email alert when an unencrypted DB instance or DB cluster is created. The solution also must terminate the unencrypted DB instance or DB cluster.

A developer has created an AWS Lambda function in a company's development account. The Lambda function requires the use of an AWS Key Management Service (AWS KMS) customer managed key that exists in a security account that the company's security team controls. The developer obtains the ARN of the KMS key from a previous Lambda function in the development account. The previous Lambda function had been working properly with the KMS key. When the developer uses the ARN and tests the new Lambda function an error message states that access is denied to the KMS key in the security account. The developer tests the previous Lambda function that uses the same KMS key and discovers that the previous Lambda function still can encrypt data as expected. A security engineer must resolve the problem so that the new Lambda function in the development account can use the KMS key from the security account. Which combination of steps should the security engineer take to meet these requirements? (Select TWO.)

Question 182

A company has recently recovered from a security incident that required the restoration of Amazon EC2 instances from snapshots.

After performing a gap analysis of its disaster recovery procedures and backup strategies, the company is concerned that, next time, it will not be able to recover the EC2 instances if the AWS account was compromised and Amazon EBS snapshots were deleted.

All EBS snapshots are encrypted using an AWS KMS CMK.

Which solution would solve this problem?

Create a new Amazon S3 bucket. Use EBS lifecycle policies to move EBS snapshots to the new S3 bucket. Move snapshots to Amazon S3 Glacier using lifecycle policies, and apply Glacier Vault Lock policies to prevent deletion.

Use AWS Systems Manager to distribute a configuration that performs local backups of all attached disks to Amazon S3.

Create a new AWS account with limited privileges. Allow the new account to access the AWS KMS key used to encrypt the EBS snapshots, and copy the encrypted snapshots to the new account on a recurring basis.

Use AWS Backup to copy EBS snapshots to Amazon S3.

Question 183

A company developed an application by using AWS Lambda, Amazon S3, Amazon Simple Notification Service (Amazon SNS), and Amazon DynamoDB. An external application puts objects into the company's S3 bucket and tags the objects with date and time. A Lambda function periodically pulls data from the company's S3 bucket based on date and time tags and inserts specific values into a DynamoDB table for further processing.

The data includes personally identifiable information (Pll). The company must remove data that is older than 30 days from the S3 bucket and the DynamoDB table.

Which solution will meet this requirement with the MOST operational efficiency?

Update the Lambda function to add a TTL S3 flag to S3 objects. Create an S3 Lifecycle policy to expire objects that are older than 30 days by using the TTL S3 flag.

Create an S3 Lifecycle policy to expire objects that are older than 30 days. Update the Lambda function to add the TTL attribute in the DynamoDB table. Enable TTL on the DynamoDB table to expire entires that are older than 30 days based on the TTL attribute.

Create an S3 Lifecycle policy to expire objects that are older than 30 days and to add all prefixes to the S3 bucket. Update the Lambda function to delete entries that are older than 30 days.

Create an S3 Lifecycle policy to expire objects that are older than 30 days by using object tags. Update the Lambda function to delete entries that are older than 30 days.

Question 187

A company that uses AWS Organizations is migrating workloads to AWS. The compa-nys application team determines that the workloads will use Amazon EC2 instanc-es, Amazon S3 buckets, Amazon DynamoDB tables, and Application Load Balancers. For each resource type, the company mandates that deployments must comply with the following requirements:

* All EC2 instances must be launched from approved AWS accounts.

Question 190

A company is using AWS WAF to protect a customized public API service that is based on Amazon EC2 instances. The API uses an Application Load Balancer.

The AWS WAF web ACL is configured with an AWS Managed Rules rule group. After a software upgrade to the API and the client application, some types of requests are no longer working and are causing application stability issues. A security engineer discovers that AWS WAF logging is not turned on for the web ACL.

The security engineer needs to immediately return the application to service, resolve the issue, and ensure that logging is not turned off in the future. The security engineer turns on logging for the web ACL and specifies Amazon Cloud-Watch Logs as the destination.

Which additional set of steps should the security engineer take to meet the re-quirements?

Edit the rules in the web ACL to include rules with Count actions. Review the logs to determine which rule is blocking the request. Modify the IAM policy of all AWS WAF administrators so that they cannot remove the log-ging configuration for any AWS WAF web ACLs.
