An organization wants to deploy a three-tier web application whereby the application servers run on Amazon EC2 instances. These EC2 instances need access to credentials that they will use to authenticate their SQL connections to an Amazon RDS DB instance. Also, AWS Lambda functions must issue queries to the RDS database by using the same database credentials.
The credentials must be stored so that the EC2 instances and the Lambda functions can access them. No other access is allowed. The access logs must record when the credentials were accessed and by whom.
What should the Security Engineer do to meet these requirements?

A. Store the database credentials in AWS Key Management Service (AWS KMS). Create an IAM role with access to AWS KMS by using the EC2 and Lambda service principals in the role's trust policy. Add the role to an EC2 instance profile. Attach the instance profile to the EC2 instances. Set up Lambda to use the new role for execution. B. Store the database credentials in AWS KMS. Create an IAM role with access to KMS by using the EC2 and Lambda service principals in the role's trust policy. Add the role to an EC2 instance profile. Attach the instance profile to the EC2 instances and the Lambda function. C. Store the database credentials in AWS Secrets Manager. Create an IAM role with access to Secrets Manager by using the EC2 and Lambda service principals in the role's trust policy. Add the role to an EC2 instance profile. Attach the instance profile to the EC2 instances and the Lambda function. D. Store the database credentials in AWS Secrets Manager. Create an IAM role with access to Secrets Manager by using the EC2 and Lambda service principals in the role's trust policy. Add the role to an EC2 instance profile. Attach the instance profile to the EC2 instances. Set up Lambda to use the new role for execution.

A company has a customer master key (CMK) with imported key materials. Company policy requires that all encryption keys must be rotated every year.
What can be done to implement the above policy?

A. Enable automatic key rotation annually for the CMK. B. Use AWS Command Line Interface to create an AWS Lambda function to rotate the existing CMK annually. C. Import new key material to the existing CMK and manually rotate the CMK. D. Create a new CMK, import new key material to it, and point the key alias to the new CMK.

A water utility company uses a number of Amazon EC2 instances to manage updates to a fleet of 2,000 Internet of Things (IoT) field devices that monitor water quality. These devices each have unique access credentials.
An operational safety policy requires that access to specific credentials is independently auditable.
What is the MOST cost-effective way to manage the storage of credentials?

A. Use AWS Systems Manager to store the credentials as Secure Strings Parameters. Secure by using an AWS KMS key. B. Use AWS Key Management System to store a master key, which is used to encrypt the credentials. The encrypted credentials are stored in an Amazon RDS instance. C. Use AWS Secrets Manager to store the credentials. D. Store the credentials in a JSON file on Amazon S3 with server-side encryption.

An organization is using Amazon CloudWatch Logs with agents deployed on its Linux Amazon EC2 instances. The agent configuration files have been checked and the application log files to be pushed are configured correctly. A review has identified that logging from specific instances is missing.
Which steps should be taken to troubleshoot the issue? (Choose two.)

A. Use an EC2 run command to confirm that the "awslogs" service is running on all instances. B. Verify that the permissions used by the agent allow creation of log groups/streams and to put log events. C. Check whether any application log entries were rejected because of invalid time stamps by reviewing /var/cwlogs/rejects.log. D. Check that the trust relationship grants the service "cwlogs.amazonaws.com" permission to write objects to the Amazon S3 staging bucket. E. Verify that the time zone on the application servers is in UTC.

A Security Engineer must design a solution that enables the incident Response team to audit for changes to a user's IAM permissions in the case of a security incident.
How can this be accomplished?

A. Use AWS Config to review the IAM policy assigned to users before and after the incident. B. Run the GenerateCredentialReport via the AWS CLI, and copy the output to Amazon S3 daily for auditing purposes. C. Copy AWS CloudFormation templates to S3, and audit for changes from the template. D. Use Amazon EC2 Systems Manager to deploy images, and review AWS CloudTrail logs for changes.

A company has complex connectivity rules governing ingress, egress, and communications between Amazon EC2 instances. The rules are so complex that they cannot be implemented within the limits of the maximum number of security groups and network access control lists (network ACLs).
What mechanism will allow the company to implement all required network rules without incurring additional cost?

A. Configure AWS WAF rules to implement the required rules. B. Use the operating system built-in, host-based firewall to implement the required rules. C. Use a NAT gateway to control ingress and egress according to the requirements. D. Launch an EC2-based firewall product from the AWS Marketplace, and implement the required rules in that product.

An IAM user with fill EC2 permissions could bot start an Amazon EC2 instance after it was stopped for a maintenance task. Upon starting the instance, the instance state would change to `Pending`, but after a few seconds, it would switch back to `Stopped`.
An inspection revealed that the instance has attached Amazon EBS volumes that were encrypted by using a Customer Master Key (CMK). When these encrypted volumes were detached, the IAM user was able to start the EC2 instances.
The IAM user policy is as follows:
What additional items need to be added to the IAM user policy? (Choose two.)

A. kms:GenerateDataKey B. kms:Decrypt C. kms:CreateGrant D. "Condition": { "Bool": { "kms:ViaService": "ec2.us-west-2.amazonaws.com" } } E. "Condition": { "Bool": { "kms:GrantIsForAWSResource": true } }

A Security Administrator has a website hosted in Amazon S3. The Administrator has been given the following requirements:
- Users may access the website by using an Amazon CloudFront distribution.
- Users may not access the website directly by using an Amazon S3 URL.
Which configurations will support these requirements? (Choose two.)

A. Associate an origin access identity with the CloudFront distribution. B. Implement a "Principal": "cloudfront.amazonaws.com" condition in the S3 bucket policy. C. Modify the S3 bucket permissions so that only the origin access identity can access the bucket contents. D. Implement security groups so that the S3 bucket can be accessed only by using the intended CloudFront distribution. E. Configure the S3 bucket policy so that it is accessible only through VPC endpoints, and place the CloudFront distribution into the specified VPC.

A Security Engineer has created an Amazon CloudWatch event that invokes an AWS Lambda function daily. The Lambda function runs an Amazon Athena query that checks AWS CloudTrail logs in Amazon S3 to detect whether any IAM user accounts or credentials have been created in the past 30 days. The results of theAthena query are created in the same S3 bucket. The Engineer runs a test execution of the Lambda function via the AWS Console, and the function runs successfully.
After several minutes, the Engineer finds that his Athena query has failed with the error message: `Insufficient Permissions`. The IAM permissions of the SecurityEngineer and the Lambda function are shown below:Security Engineer -Lambda function execution role -What is causing the error?

A. The Lambda function does not have permissions to start the Athena query execution. B. The Security Engineer does not have permissions to start the Athena query execution. C. The Athena service does not support invocation through Lambda. D. The Lambda function does not have permissions to access the CloudTrail S3 bucket.

A company requires that IP packet data be inspected for invalid or malicious content.
Which of the following approaches achieve this requirement? (Choose two.)

A. Configure a proxy solution on Amazon EC2 and route all outbound VPC traffic through it. Perform inspection within proxy software on the EC2 instance. B. Configure the host-based agent on each EC2 instance within the VPC. Perform inspection within the host-based agent. C. Enable VPC Flow Logs for all subnets in the VPC. Perform inspection from the Flow Log data within Amazon CloudWatch Logs. D. Configure Elastic Load Balancing (ELB) access logs. Perform inspection from the log data within the ELB access log files. E. Configure the CloudWatch Logs agent on each EC2 instance within the VPC. Perform inspection from the log data within CloudWatch Logs.
