A company runs an online game on AWS. When players sign up for the game, their username and password credentials are stored in an Amazon Aurora database.
The number of users has grown to hundreds of thousands of players. The number of requests for password resets and login assistance has become a burden for the company's customer service team.
The company needs to implement a solution to give players another way to log in to the game.
The solution must remove the burden of password resets and login assistance while securely protecting each player's credentials.

A security engineer has designed a VPC to segment private traffic from public traffic. The VPC includes two Availability Zones. The security engineer has provisioned each Availability Zone with one private subnet and one public subnet. The security engineer has created three route tables for use with the environment. One route table is for the public subnets, and two route tables are for the private subnets (one route table for the private subnet in each Availability Zone).
The security engineer discovers that all four subnets are attempting to route traffic out through the internet gateway that is attached to the VPC.
Which combination of steps should the security engineer take to remediate this scenario? (Select TWO.)

A company must retain backup copies of Amazon RDS DB instances and Amazon Elastic Block Store (Amazon EBS) volumes. The company must retain the backup copies in data centers that are several hundred miles apart. Which solution will meet these requirements with the LEAST operational overhead?

A company uses an organization in AWS Organizations to manage multiple AWS accounts. A security engineer creates a WAF policy in AWS Firewall Manager in the us-east-1 Region. The security engineer sets the policy scope to apply to resources that are tagged withWAF- protected:truein one of the member accounts in the organization. The security engineer sets up a configuration to automatically remediate any noncompliant resources.
In a member account, the security engineer attempts to protect an Amazon API Gateway REST API in the us-east-1 Region by using a web ACL. However, after several minutes, the REST API is still not associated with the web ACL.
What is the likely cause of this issue?

A company creates AWS Lambda functions from container images that are stored in Amazon Elastic Container Registry (Amazon ECR). The company needs to identify any software vulnerabilities in the container images and any code vulnerabilities in the Lambda functions.
Which solution will meet these requirements?

A security engineer needs to configure DDoS protection for a Network Load Balancer (NLB) with an Elastic IP address. The security engineer wants to set up an AWS WAF web ACL with a rate- based rule statement to protect the NLB.
The security engineer needs to determine a rate limit that will not block legitimate traffic. The security engineer has configured the rule statement to aggregate based on the source IP address.
How should the security engineer configure the rule to protect the NLB?

A company uses AWS Organizations. The company has teams that use an AWS CloudHSM hardware security module (HSM) that is hosted in a central AWS account. One of the teams creates its own new dedicated AWS account and wants to use the HSM that is hosted in the central account.

An IAM user receives an Access Denied message when the user attempts to access objects in an Amazon S3 bucket. The user and the S3 bucket are in the same AWS account. The S3 bucket is configured to use server-side encryption with AWS KMS keys (SSE-KMS) to encrypt all of its objects at rest by using a customer managed key from the same AWS account. The S3 bucket has no bucket policy defined. The IAM user has been granted permissions through an IAM policy that allows thekms:Decryptpermission to the customer managed key. The IAM policy also allows thes3:List* ands3:Get* permissions for the S3 bucket and its objects.
Which of the following is a possible reason that the IAM user cannot access the objects in the S3 bucket?

A company needs to deploy AWS CloudFormation templates that configure sensitive database credentials. The company already uses AWS Key Management Service (AWS KMS) and AWS Secrets Manager. Which solution will meet the requirements?
