Question 48

A network engineer is working on a large migration effort from an on-premises data center to an AWS Control Tower based multi-account environment. The environment

has a transit gateway that is deployed to a central network services account. The central network services account has been shared with an organization in AWS

Organizations through AWS Resource Access Manager (AWS RAM).

A shared services account also exists in the environment. The shared services account hosts workloads that need to be shared with the entire organization.

The network engineer needs to create a solution to automate the deployment of common network components across the environment. The solution must provision a

VPC for application workloads to each new and existing member account. The VPCs must be connected to the transit gateway in the central network services account.

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

Options:

Deploy an AWS Lambda function to the shared services account. Program the Lambda function to assume a role in the new and existing member accounts

to provision the necessary network infrastructure.

Update the existing accounts with an Account Factory Customization (AFC). Select the same AFC when provisioning new accounts.

Create an AWS CloudFormation template that describes the infrastructure that needs to be created in each account. Upload the template as an AWS

Service Catalog product to the shared services account.

Deploy an Amazon EventBridge rule on a default event bus in the shared services account. Configure the EventBridge rule to react to AWS Control Tower

CreateManagedAccount lifecycle events and to invoke the AWS Lambda function.

Create an AWSControlTowerBlueprintAccess role in the shared services account.

Create an AWSControlTowerBlueprintAccess role in each member account.

Discussion

Answer:

A, C, D

Explanation:

The correct answer is A, C, and D. These steps will meet the requirements with the least operational overhead because:

•Step A will deploy an AWS Lambda function to the shared services account that can automate the network infrastructure provisioning in each member account by assuming a role with the necessary permissions.

•Step C will create an AWS CloudFormation template that describes the VPC and the transit gateway attachment for each account. This template can be uploaded as an AWS Service Catalog product to the shared services account, which can be used by the AWS Lambda function to create the network resources in each member account.

•Step D will deploy an Amazon EventBridge rule on a default event bus in the shared services account that can react to AWS Control Tower lifecycle events, such as creating a new managed account. This rule can invoke the AWS Lambda function to provision the network infrastructure in the new account.

The other steps are incorrect because:

•Step B will update the existing accounts with an Account Factory Customization (AFC), which is a feature of AWS Control Tower that allows you to customize the account creation process with AWS CloudFormation templates. However, this step will not automate the network infrastructure provisioning for the existing accounts, as it only applies to the new accounts created through the Account Factory. Moreover, this step will require additional operational overhead to maintain the AFC templates and products.

•Step E will create an AWSControlTowerBlueprintAccess role in the shared services account, which is a role that allows AWS Control Tower to access the AWS Service Catalog products in the shared services account. However, this step is not necessary for the automation solution, as the AWS Lambda function can access the AWS Service Catalog products directly without using this role.

•Step F will create an AWSControlTowerBlueprintAccess role in each member account, which is a role that allows AWS Control Tower to access the AWS Service Catalog products in the member accounts. However, this step is not necessary for the automation solution, as the AWS Lambda function can access the AWS Service Catalog products in the shared services account without using this role.

A company ran out of IP address space in one of the Availability Zones in an AWS Region that the company uses. The Availability Zone that is out of space is assigned the

10.10.1.0/24 CIDR block. The company manages its networking configurations in an AWS CloudFormation stack. The company's VPC is assigned the 10.10.0.0/16 CIDR

block and has available capacity in the 10.10.1.0/22 CIDR block.

How should a network specialist add more IP address space in the existing VPC with the LEAST operational overhead?

A.Update the AWS :: EC2 :: Subnet resource for the Availability Zone in the CloudFormation stack. Change the CidrBlock property to 10.10.1.0/22.

B.Update the AWS :: EC2 :: VPC resource in the CloudFormation stack. Change the CidrBlock property to 10.10.1.0/22.

C.Copy the CloudFormation stack. Set the AWS :: EC2 :: VPC resource CidrBlock property to 10.10.0.0/16. Set the AWS :: EC2 :: Subnet resource CidrBlock property to 10.10.1.0/22 for the Availability Zone.

D.Create a new AWS :: EC2 :: Subnet resource for the Availability Zone in the CloudFormation stack. Set the CidrBlock property to 10.10.2.0/24.

Answer: D

Question 49

A company has developed an application on AWS that will track inventory levels of vending machines and initiate the restocking process automatically. The company plans to integrate this application with vending machines and deploy the vending machines in several markets around the world. The application resides in a VPC in the us-east-1 Region. The application consists of an Amazon Elastic Container Service (Amazon ECS) cluster behind an Application Load Balancer (ALB). The communication from the vending machines to the application happens over HTTPS.

The company is planning to use an AWS Global Accelerator accelerator and configure static IP addresses of the accelerator in the vending machines for application endpoint access. The application must be accessible only through the accelerator and not through a direct connection over the internet to the ALB endpoint.

Which solution will meet these requirements?

Options:

Configure the ALB in a private subnet of the VPC. Attach an internet gateway without adding routes in the subnet route tables to point to the internet gateway. Configure the accelerator with endpoint groups that include the ALB endpoint. Configure the ALB’s security group to only allow inbound traffic from the internet on the ALB listener port.

Configure the ALB in a private subnet of the VPC. Configure the accelerator with endpoint groups that include the ALB endpoint. Configure the ALB's security group to only allow inbound traffic from the internet on the ALB listener port.

Question 50

A company's application is deployed on Amazon EC2 instances in a single VPC in an AWS Region. The EC2 instances are running in two Availability Zones. The company decides to use a fleet of traffic inspection instances from AWS Marketplace to inspect traffic between the VPC and the internet. The company is performing tests before the company deploys the architecture into production.

The fleet is located in a shared inspection VPC behind a Gateway Load Balancer (GWLB). To minimize the cost of the solution, the company deployed only one inspection instance in each Availability Zone that the application uses.

During tests, a network engineer notices that traffic inspection works as expected when the network is stable. However, during maintenance of the inspection instances, the internet sessions time out for some application instances. The application instances are not able to establish new sessions.

Which combination of steps will remediate these issues? (Choose two.)

Options:

Deploy one inspection instance in the Availability Zones that do not have inspection instances deployed.

Deploy one additional inspection instance in each Availability Zone where the inspection instances are deployed.

Enable the cross-zone load balancing attribute for the GWLB.

Deploy inspection instances in an Auto Scaling group. Define a scaling policy that is based on CPU load.

Attach the GWLB to all Availability Zones in the Region.

Question 51

A company has several production applications across different accounts in the AWS Cloud. The company operates from the us-east-1 Region only. Only certain partner companies can access the applications. The applications are running on Amazon EC2 instances that are in an Auto Scaling group behind an Application Load Balancer (ALB). The EC2 instances are in private subnets and allow traffic only from the ALB. The ALB is in a public subnet and allows inbound traffic only from partner network IP address ranges over port 80.

When the company adds a new partner, the company must allow the IP address range of the partner network in the security group that is associated with the ALB in each account. A network engineer must implement a solution to centrally manage the partner network IP address ranges.

Which solution will meet these requirements in the MOST operationally efficient manner?

Options:

Create an Amazon DynamoDB table to maintain all IP address ranges and security groups that need to be updated. Update the DynamoDB table with the new IP address range when the company adds a new partner. Invoke an AWS Lambda function to read new IP address ranges and security groups from the DynamoDB table to update the security groups. Deploy this solution in all accounts.

Create a new prefix list. Add all allowed IP address ranges to the prefix list. Use Amazon EventBridge (Amazon CloudWatch Events) rules to invoke an AWS Lambda function to update security groups whenever a new IP address range is added to the prefix list. Deploy this solution in all accounts.

Create a new prefix list. Add all allowed IP address ranges to the prefix list. Share the prefix list across different accounts by using AWS Resource Access Manager (AWS RAM). Update security groups to use the prefix list instead of the partner IP address range. Update the prefix list with the new IP address range when the company adds a new partner.

Create an Amazon S3 bucket to maintain all IP address ranges and security groups that need to be updated. Update the S3 bucket with the new IP address range when the company adds a new partner. Invoke an AWS Lambda function to read new IP address ranges and security groups from the S3 bucket to update the security groups. Deploy this solution in all accounts.
