Question # 101

A Security Engineer creates an Amazon S3 bucket policy that denies access to all users. A few days later, the Security Engineer adds an additional statement to the bucket policy to allow read-only access to one other employee. Even after updating the policy, the employee still receives an access denied message.

What is the likely cause of this access denial?

The ACL in the bucket needs to be updated

The IAM policy does not allow the user to access the bucket

It takes a few minutes for a bucket policy to take effect

The allow permission is being overridden by the deny

Question # 102

A company has a web server in the AWS Cloud. The company will store the content for the web server in an Amazon S3 bucket. A security engineer must use an Amazon CloudFront distribution to speed up delivery of the content. None of the files can be publicly accessible from the S3 bucket direct.

Which solution will meet these requirements?

Configure the permissions on the individual files in the S3 bucket so that only the CloudFront distribution has access to them.

Create an origin access identity (OAI). Associate the OAI with the CloudFront distribution. Configure the S3 bucket permissions so that only the OAI can access the files in the S3 bucket.

Create an S3 role in AWS Identity and Access Management (IAM). Allow only the CloudFront distribution to assume the role to access the files in the S3 bucket.

Create an S3 bucket policy that uses only the CloudFront distribution ID as the principal and the Amazon Resource Name (ARN) as the target.

Question # 103

A company hosts a public website on an Amazon EC2 instance. HTTPS traffic must be able to access the website. The company uses SSH for management of the web server.

The website is on the subnet 10.0.1.0/24. The management subnet is 192.168.100.0/24. A security engineer must create a security group for the EC2

instance.

Which combination of steps should the security engineer take to meet these requirements in the MOST secure manner? (Select TWO.)

Allow port 22 from source 0.0.0.0/0.

Allow port 443 from source 0.0.0.0/0.

Allow port 22 from 192.168.100.0/24.

Allow port 22 from 10.0.1.0/24.

Allow port 443 from 10.0.1.0/24.

Question # 104

A company deploys a distributed web application on a fleet of Amazon EC2 instances. The fleet is behind an Application Load Balancer (ALB) that will be configured to terminate the TLS connection. All TLS traffic to the ALB must stay secure, even if the certificate private key is compromised.

How can a security engineer meet this requirement?

Create an HTTPS listener that uses a certificate that is managed by IAM Certificate Manager (ACM).

Create an HTTPS listener that uses a security policy that uses a cipher suite with perfect toward secrecy (PFS).

Create an HTTPS listener that uses the Server Order Preference security feature.

Create a TCP listener that uses a custom security policy that allows only cipher suites with perfect forward secrecy (PFS).

Question # 105

A company is using Amazon Elastic Container Service (Amazon ECS) to run its container-based application on AWS. The company needs to ensure that the container images contain no severe vulnerabilities. The company also must ensure that only specific IAM roles and specific AWS accounts can access the container images.

Which solution will meet these requirements with the LEAST management overhead?

Pull images from the public container registry. Publish the images to Amazon Elastic Container Registry (Amazon ECR) repositories with scan on push configured in a centralized AWS account.Use a CI/CD pipeline to deploy the images to different AWS accounts. Use identity-based policies to restrict access to which IAM principals can access the images.

Pull images from the public container registry. Publish the images to a private container registry that is hosted on Amazon EC2 instances in a centralized AWS account. Deploy host-based container scanning tools to EC2 instances that run Amazon ECS. Restrict access to the container images by using basic authentication over HTTPS.

Pull images from the public container registry. Publish the images to Amazon Elastic Container Registry (Amazon ECR) repositories with scan on push configured in a centralized AWS account. Use a CI/CD pipeline to deploy the images to different AWS accounts. Use repository policies and identity-based policies to restrict access to which IAM principals and accounts can access the images.

Pull images from the public container registry. Publish the images to AWS CodeArtifact repositories in a centralized AWS account. Use a CI/CD pipeline to deploy the images to different AWS accounts. Use repository policies and identity-based policies to restrict access to which IAM principals and accounts can access the images.

Answer:

Explanation:

The correct answer is C. Pull images from the public container registry. Publish the images to Amazon Elastic Container Registry (Amazon ECR) repositories with scan on push configured in a centralized AWS account. Use a CI/CD pipeline to deploy the images to different AWS accounts. Use repository policies and identity-based policies to restrict access to which IAM principals and accounts can access the images.

This solution meets the requirements because:

Amazon ECR is a fully managed container registry service that supports Docker and OCI images and artifacts1. It integrates with Amazon ECS and other AWS services to simplify the development and deployment of container-based applications.

Amazon ECR provides image scanning on push, which uses the Common Vulnerabilities and Exposures (CVEs) database from the open-source Clair project to detect software vulnerabilities in container images2.The scan results are available in the AWS Management Console, AWS CLI, orAWS SDKs2.

Amazon ECR supports cross-account access to repositories, whichallows sharing images across multiple AWS accounts3.This can be achieved by using repository policies, which are resource-based policies that specify which IAM principals and accounts can access the repositories and what actions they can perform4.Additionally, identity-based policies can be used to control which IAM roles in each account can access the repositories5.

The other options are incorrect because:

A. This option does not use repository policies to restrict cross-account access to the images, which is a requirement.Identity-based policies alone are not sufficient to control access to Amazon ECR repositories5.

B. This option does not use Amazon ECR, which is a fully managed service that provides image scanning and cross-account access features. Hosting a private container registry on EC2 instances would require more management overhead and additional security measures.

D.This option uses AWS CodeArtifact, which is a fully managed artifact repository service that supports Maven, npm, NuGet, PyPI, and generic package formats6. However, AWS CodeArtifact does not support Docker or OCI container images, which are required for Amazon ECS applications.

Question # 106

A company finds that one of its Amazon EC2 instances suddenly has a high CPU usage. The company does not know whether the EC2 instance is compromised or whether the operating system is performing background cleanup.

Which combination of steps should a security engineer take before investigating the issue? (Select THREE.)

Disable termination protection for the EC2 instance if termination protection has not been disabled.

Enable termination protection for the EC2 instance if termination protection has not been enabled.

Take snapshots of the Amazon Elastic Block Store (Amazon EBS) data volumes that are attached to theEC2 instance.

Remove all snapshots of the Amazon Elastic Block Store (Amazon EBS) data volumes that are attached to the EC2 instance.

Capture the EC2 instance metadata, and then tag the EC2 instance as under quarantine.

Immediately remove any entries in the EC2 instance metadata that contain sensitive information.

Question # 107

A company uses infrastructure as code (IaC) to create AWS infrastructure. The company writes the code as AWS CloudFormation templates to deploy the infrastructure. The company has an existing CI/CD pipeline that the company can use to deploy these templates.

After a recent security audit, the company decides to adopt a policy-as-code approach to improve the company's security posture on AWS. The company must prevent the deployment of any infrastructure that would violate a security policy, such as an unencrypted Amazon Elastic Block Store (Amazon EBS) volume.

Which solution will meet these requirements?

Turn on AWS Trusted Advisor. Configure security notifications as webhooks in the preferences section of the CI/CD pipeline.

Turn on AWS Config. Use the prebuilt rules or customized rules. Subscribe the CI/CD pipeline to an Amazon Simple Notification Service (Amazon SNS) topic that receives notifications from AWS Config.

Create rule sets in AWS CloudFormation Guard. Run validation checks for CloudFormation templates as a phase of the CI/CD process.

Create rule sets as SCPs. Integrate the SCPs as a part of validation control in a phase of the CI/CD process.

Answer:

Explanation:

The correct answer is C. Create rule sets in AWS CloudFormation Guard. Run validation checks for CloudFormation templates as a phase of the CI/CD process.

This answer is correct because AWS CloudFormation Guard is a tool that helps you implement policy-as-code for your CloudFormation templates. You can use Guard to write rules that define your security policies, such as requiring encryption for EBS volumes, and then validate your templates against those rules before deploying them.You can integrate Guard into your CI/CD pipeline as a step that runs the validation checks and prevents the deploymentof any non-compliant templates12.

The other options are incorrect because:

A. Turning on AWS Trusted Advisor and configuring security notifications as webhooks in the preferences section of the CI/CD pipeline is not a solution, because AWS Trusted Advisor is not a policy-as-code tool, but a service that provides recommendations to help you follow AWS best practices.Trusted Advisor does not allow you to define your own security policies or validate your CloudFormationtemplates against them3.

B. Turning on AWS Config and using the prebuilt or customized rules is not a solution, because AWS Config is not a policy-as-code tool, but a service that monitors and records the configuration changes of your AWS resources.AWS Config does not allow you to validate your CloudFormation templates before deploying them, but onlyevaluates the compliance of your resources after they are created4.

D. Creating rule sets as SCPs and integrating them as a part of validation control in a phase of the CI/CD process is not a solution, because SCPs are not policy-as-code tools, but policies that you can use to manage permissions in your AWS Organizations.SCPs do not allow you to validate your CloudFormation templates, but only restrict the actions that users and roles can perform in your accounts5.

Question # 108

A company's security engineer wants to receive an email alert whenever Amazon GuardDuty, AWS Identity and Access Management Access Analyzer, or Amazon Made generate a high-severity security finding. The company uses AWS Control Tower to govern all of its accounts. The company also uses AWS Security Hub with all of the AWS service integrations turned on.

Which solution will meet these requirements with the LEAST operational overhead?

Set up separate AWS Lambda functions for GuardDuty, 1AM Access Analyzer, and Macie to call each service's public API to retrieve high-severity findings. Use Amazon Simple Notification Service (Amazon SNS) to send the email alerts. Create an Amazon EventBridge rule to invoke the functions on a schedule.

Create an Amazon EventBridge rule with a pattern that matches Security Hub findings events with high severity. Configure the rule to send the findings to a target Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the desired email addresses to the SNS topic.

Create an Amazon EventBridge rule with a pattern that matches AWS Control Tower events with high severity. Configure the rule to send the findings to a target Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the desired email addresses to the SNS topic.

Host an application on Amazon EC2 to call the GuardDuty, 1AM Access Analyzer, and Macie APIs. Within the application, use the Amazon Simple Notification Service (Amazon SNS) API to retrieve high-severity findings and to send the findings to an SNS topic. Subscribe the desired email addresses to the SNS topic.

Question # 109

A company has several workloads running on AWS. Employees are required to authenticate using on-premises ADFS and SSO to access the AWS Management

Console. Developers migrated an existing legacy web application to an Amazon EC2 instance. Employees need to access this application from anywhere on the internet, but currently, there is no authentication system built into the application.

How should the Security Engineer implement employee-only access to this system without changing the application?

Place the application behind an Application Load Balancer (ALB). Use Amazon Cognito as authentication for the ALB. Define a SAML-based Amazon Cognito user pool and connect it to ADFS.

Implement AWS SSO in the master account and link it to ADFS as an identity provider. Define the EC2 instance as a managed resource, then apply an IAM policy on the resource.

Define an Amazon Cognito identity pool, then install the connector on the Active Directory server. Use the Amazon Cognito SDK on the application instance to authenticate the employees using their Active Directory user names and passwords.

Create an AWS Lambda custom authorizer as the authenticator for a reverse proxy on Amazon EC2. Ensure the security group on Amazon EC2 only allows access from the Lambda function.

Question # 110

A developer signed in to a new account within an IAM Organization organizational unit (OU) containing multiple accounts. Access to the Amazon $3 service is restricted with the following SCP.
