Question # 12

A company is migrating its container-based workloads to an AWS Organizations multi-account environment. The environment consists of application workload accounts that the company uses to deploy and run the containerized workloads. The company has also provisioned a shared services account tor shared workloads in the organization.

The company must follow strict compliance regulations. All container images must receive security scanning before they are deployed to any environment. Images can be consumed by downstream deployment mechanisms after the images pass a scan with no critical vulnerabilities. Pre-scan and post-scan images must be isolated from one another so that a deployment can never use pre-scan images.

A DevOps engineer needs to create a strategy to centralize this process.

Which combination of steps will meet these requirements with the LEAST administrative overhead? (Select TWO.)

Create Amazon Elastic Container Registry (Amazon ECR) repositories in the shared services account: one repository for each pre-scan image and one repository for each post-scan image. Configure Amazon ECR image scanning to run on new image pushes to the pre-scan repositories. Use resource-based policies to grant the organization write access to the pre-scan repositories and read access to the post-scan repositories.

Create pre-scan Amazon Elastic Container Registry (Amazon ECR) repositories in each account that publishes container images. Create repositories for post-scan images in the shared services account. Configure Amazon ECR image scanning to run on new image pushes to the pre-scan repositories. Use resource-based policies to grant the organization read access to the post-scan repositories.

Configure image replication for each image from the image ' s pre-scan repository to the image ' s post-scan repository.

Create a pipeline in AWS CodePipeline for each pre-scan repository. Create a source stage that runs when new images are pushed to the pre-scan repositories. Create a stage that uses AWS CodeBuild as the action provider. Write a buildspec.yaml definition that determines the image scanning status and pushes images without critical vulnerabilities lo the post-scan repositories.

Create an AWS Lambda function. Create an Amazon EventBridge rule that reacts to image scanning completed events and invokes the Lambda function. Write function code that determines the image scanning status and pushes images without critical vulnerabilities to the post-scan repositories.

Answer:

A, C

Explanation:

 Step 1: Centralizing Image Scanning in a Shared Services Account

The first requirement is to centralize the image scanning process, ensuring pre-scan and post-scan images are stored separately. This can be achieved by creating separate pre-scan and post-scan repositories in the shared services account, with the appropriate resource-based policies to control access.

Action: Create separate ECR repositories for pre-scan and post-scan images in the shared services account. Configure resource-based policies to allow write access to pre-scan repositories and read access to post-scan repositories.

Why: This ensures that images are isolated before and after the scan, following the compliance requirements.

[Reference: AWS documentation on Amazon ECR and resource-based policies., This corresponds to Option A: Create Amazon Elastic Container Registry (Amazon ECR) repositories in the shared services account: one repository for each pre-scan image and one repository for each post-scan image. Configure Amazon ECR image scanning to run on new image pushes to the pre-scan repositories. Use resource-based policies to grant the organization write access to the pre-scan repositories and read access to the post-scan repositories.,  Step 2: Replication between Pre-Scan and Post-Scan RepositoriesTo automate the transfer of images from the pre-scan repositories to the post-scan repositories (after they pass the security scan), you can configure image replication between the two repositories., Action: Set up image replication between the pre-scan and post-scan repositories to move images that have passed the security scan., Why: Replication ensures that only scanned and compliant images are available for deployment, streamlining the process with minimal administrative overhead., Reference: AWS documentation on Amazon ECR image replication., This corresponds to Option C: Configure image replication for each image from the image's pre-scan repository to the image's post-scan repository., , , ]

Question # 13

Use the Amazon CloudWatch agent to send logs from the EC2 instances to Amazon CloudWatch Logs Configure AWS CloudTrail to deliver the API logs to Amazon S3 Use CloudWatch to query both sets of logs.

Use the Amazon CloudWatch agent to send logs from the EC2 instances to Amazon CloudWatch Logs Configure AWS CloudTrail to deliver the API logs to CloudWatch Logs Use CloudWatch Logs Insights to query both sets of logs.

Use the Amazon CloudWatch agent to send logs from the EC2 instances to Amazon Kinesis Configure AWS CloudTrail to deliver the API logs to Kinesis Use Kinesis to load the data into Amazon Redshift Use Amazon Redshift to query both sets of logs.

Use the Amazon CloudWatch agent to send logs from the EC2 instances to Amazon S3 Use AWS CloudTrail to deliver the API togs to Amazon S3 Use Amazon Athena to query both sets of logs in Amazon S3.

Question # 14

A company has multiple development teams in different business units that work in a shared single AWS account All Amazon EC2 resources that are created in the account must include tags that specify who created the resources. The tagging must occur within the first hour of resource creation.

A DevOps engineer needs to add tags to the created resources that Include the user ID that created the resource and the cost center ID The DevOps engineer configures an AWS Lambda Function with the cost center mappings to tag the resources. The DevOps engineer also sets up AWS CloudTrail in the AWS account. An Amazon S3 bucket stores the CloudTrail event logs

Which solution will meet the tagging requirements?

Create an S3 event notification on the S3 bucket to invoke the Lambda function for s3. ObJectTagging:Put events. Enable bucket versioning on the S3 bucket.

Enable server access logging on the S3 bucket. Create an S3 event notification on the S3 bucket for s3. ObjectTaggIng.• events

Create a recurring hourly Amazon EventBridge scheduled rule that invokes the Larnbda function. Modify the Lambda function to read the logs from the S3 bucket

Create an Amazon EventBridge rule that uses Amazon EC2 as the event source. Configure the rule to match events delivered by CloudTraiI. Configure the rule to target the Lambda function

Question # 15

A company uses Amazon ECS with the Amazon EC2 launch type. The company requires all log data to be centralized on Amazon CloudWatch. The company’s ECS tasks failed to deploy. An error message indicates that a missing permission causes the failure. The IAM role used includes logs:CreateLogGroup, logs:CreateLogStream, and logs:PutLogEvents.

Which solution will fix the problem?

Add an IAM trust policy to the IAM role that establishes Amazon ECS as a trusted service.

Add the logs:PutDestination permission.

Remove the logs:CreateLogStream permission.

Add an IAM trust policy that establishes CloudWatch as a trusted service.

Question # 16

A DevOps engineer is working on a member account in an organization in AWS Organizations with all features enabled . The account has sensitive data stored in Amazon S3 buckets.

The DevOps engineer must ensure that all public access to S3 buckets in the account is blocked . If the account-level S3 Block Public Access settings change in the future, the changes must be reverted automatically so that all public access is blocked again.

Which solution meets these requirements?

Enable AWS Security Hub in the account. Enable the Security Hub control to evaluate the account-level Block Public Access settings. Enable automated remediation for the Security Hub control.

Set up AWS Config in the account. Create an AWS Config managed rule that evaluates the account-level Block Public Access settings. Enable automatic remediation for the rule by using a predefined AWS Systems Manager runbook to configure S3 Block Public Access settings.

In the organization’s management account, create an SCP that denies S3 actions from outside the AWS account. Attach the SCP to the member account.

Enable Amazon Macie in the account. Create an Amazon EventBridge rule with an event pattern that matches Macie policy findings. Configure the rule with an EventBridge target to run a predefined AWS Systems Manager runbook to configure S3 Block Public Access settings.

Answer:

Explanation:

Option B is the only choice that directly satisfies both requirements:

Continuously evaluate the account-level S3 Block Public Access setting

AWS Config is designed to record configuration state and evaluate resources/settings against rules over time.

A Config rule (managed rule) can check whether the account-level “S3 Block Public Access” settings are configured as required (i.e., blocking public access).

Automatically revert drift (auto-remediate) if someone changes the setting later

AWS Config Remediation can automatically trigger an AWS Systems Manager Automation runbook when the rule becomes NON_COMPLIANT .

Using an SSM Automation document/runbook that sets S3 account-level Block Public Access back to the required “blocked” configuration ensures that any future change is corrected automatically , restoring compliance without manual intervention.

Why the other options don’t fully meet the requirement:

A (Security Hub) : Security Hub primarily aggregates findings and checks controls. While it can integrate with automation, AWS Config is the standard service for configuration drift detection + automatic remediation loops for account-level posture settings. Security Hub is not the most direct “detect config drift and auto-fix” mechanism for an account setting in the way Config remediation is.

C (SCP) : An SCP can restrict API actions, but it doesn’t “revert” a changed S3 Block Public Access configuration ; it only prevents/limits what actions can be called. Also, “deny S3 actions from outside the account” is not the same as enforcing Block Public Access settings at the account level.

D (Macie + EventBridge) : Macie focuses on data discovery and sensitive data findings , not enforcing or continuously remediating S3 account-level Block Public Access configuration drift. Triggering remediation off Macie findings is indirect and not aligned to “setting changed → immediately revert.”

Question # 17

A company requires all employees to access secrets via Systems Manager Parameter Store with rotation every 60 days.

The company must add a new secret for an Amazon ElastiCache Redis cluster.

Which solution meets these requirements with the LEAST operational overhead?

Create the secret in Secrets Manager with managed rotation (60 days). Reference via Parameter Store path.

Create the secret in Parameter Store with automatic rotation (unsupported).

Create the secret in Parameter Store and Lambda rotation (manual).

Create the secret in Secrets Manager with Lambda rotation using Redis rotation template and 60-day schedule. Reference via Parameter Store path.

Question # 18

A company needs to ensure that flow logs remain configured for all existing and new VPCs in its AWS account. The company uses an AWS CloudFormation stack to manage its VPCs. The company needs a solution that will work for any VPCs that any IAM user creates.

Which solution will meet these requirements?

Add the resource to the CloudFormation stack that creates the VPCs.

Create an organization in AWS Organizations. Add the company ' s AWS account to the organization. Create an SCP to prevent users from modifying VPC flow logs.

Turn on AWS Config. Create an AWS Config rule to check whether VPC flow logs are turned on. Configure automatic remediation to turn on VPC flow logs.

Create an IAM policy to deny the use of API calls for VPC flow logs. Attach the IAM policy to all IAM users.

Answer:

Explanation:

To meet the requirements of ensuring that flow logs remain configured for all existing and new VPCs in the AWS account, the company should use AWS Config and automatic remediation. AWS Config is a service that enables customers to assess, audit, and evaluate the configurations of their AWS resources. AWS Config continuously monitors and records the configuration changes of the AWS resources and evaluates them against desired configurations. Customers can use AWS Config rules to define the desired configuration state of their AWS resources and trigger actions when a resource configuration violates a rule.

One of the AWS Config rules that customers can use is vpc-flow-logs-enabled, which checks whether VPC flow logs are enabled for all VPCs in an AWS account. Customers can also configure automatic remediation for this rule, which means that AWS Config will automatically enable VPC flow logs for any VPCs that do not have them enabled. Customers can specify the destination (CloudWatch Logs or S3) and the traffic type (all, accept, or reject) for the flow logs as remediation parameters. By using AWS Config and automatic remediation, the company can ensure that flow logs remain configured for all existing and new VPCs in its AWS account, regardless of who creates them or how they are created.

The other options are not correct because they do not meet the requirements or follow best practices. Adding the resource to the CloudFormation stack that creates the VPCs is not a sufficient solution because it will only work for VPCs that are created by using the CloudFormation stack. It will not work for VPCs that are created by using other methods, such as the console or the API. Creating an organization in AWS Organizations and creating an SCP to prevent users from modifying VPC flow logs is not a good solution because it will not ensure that flow logs are enabled for all VPCs in the first place. It will only prevent users from disabling or changing flow logs after they are enabled. Creating an IAM policy to deny the use of API calls for VPC flow logs and attaching it to all IAM users is not a valid solution because it will prevent users from enabling or disabling flow logs at all. It will also not work for VPCs that are created by using other methods, such as the console or CloudFormation.

Question # 19

A company operates sensitive workloads across the AWS accounts that are in the company ' s organization in AWS Organizations The company uses an IP address range to delegate IP addresses for Amazon VPC CIDR blocks and all non-cloud hardware.

The company needs a solution that prevents principals that are outside the company ' s IP address range from performing AWS actions In the organization ' s accounts

Which solution will meet these requirements?

Configure AWS Firewall Manager for the organization. Create an AWS Network Firewall policy that allows only source traffic from the company ' s IP address range Set the policy scope to all accounts in the organization.

In Organizations, create an SCP that denies source IP addresses that are outside of the company s IP address range. Attach the SCP to the organization ' s root

Configure Amazon GuardDuty for the organization. Create a GuardDuty trusted IP address list for the company ' s IP range Activate the trusted IP list for the organization.

In Organizations, create an SCP that allows source IP addresses that are inside of the company s IP address range. Attach the SCP to the organization ' s root.

Question # 20

A company has an application that is using a MySQL-compatible Amazon Aurora Multi-AZ DB cluster as the database. A cross-Region read replica has been created for disaster recovery purposes. A DevOps engineer wants to automate the promotion of the replica so it becomes the primary database instance in the event of a failure.

Which solution will accomplish this?

Configure a latency-based Amazon Route 53 CNAME with health checks so it points to both the primary and replica endpoints. Subscribe an Amazon SNS topic to Amazon RDS failure notifications from AWS CloudTrail and use that topic to invoke an AWS Lambda function that will promote the replica instance as the primary.

Create an Aurora custom endpoint to point to the primary database instance. Configure the application to use this endpoint. Configure AWS CloudTrail to run an AWS Lambda function to promote the replica instance and modify the custom endpoint to point to the newly promoted instance.

Create an AWS Lambda function to modify the application ' s AWS CloudFormation template to promote the replica, apply the template to update the stack, and point the application to the newly promoted instance. Create an Amazon CloudWatch alarm to invoke this Lambda function after the failure event occurs.

Store the Aurora endpoint in AWS Systems Manager Parameter Store. Create an Amazon EventBridge event that detects the database failure and runs an AWS Lambda function to promote the replica instance and update the endpoint URL stored in AWS Systems Manager Parameter Store. Code the application to reload the endpoint from Parameter Store if a database connection fails.
