Question # 73

A company has a transit gateway in AWS Account A. The company uses AWS Resource Access Manager (AWS RAM) to share the transit gateway so that users in other accounts can connect to multiple VPCs in the same AWS Region. AWS Account B contains a VPC (10.0.0.0/16) with subnet 10.0.0.0/24 in the us-west-2a Availability Zone and subnet 10.0.1.0/24 in the us-west-2b Availability Zone. Resources in these subnets can communicate with other VPCs.

A network engineer creates two new subnets: 10.0.2.0/24 in the us-west-2b Availability Zone and 10.0.3.0/24 in the us-west-2c Availability Zone. All the subnets share one route table. The default route 0.0.0.0/0 is pointing to the transit gateway. Resources in subnet 10.0.2.0/24 can communicate with other VPCs, but resources in subnet 10.0.3.0/24 cannot communicate with other VPCs.

What should the network engineer do so that resources in subnet 10.0.3.0/24 can communicate with other VPCs?

In Account B, add 10.0.2.0/24 and 10.0.3.0/24 as the destinations to the route table. Use the transit gateway as the target.

In Account B, update the transit gateway attachment. Attach the new subnet ID that is associated with us-west-2c to Account B's VPC.

In Account A, create a static route for 10.0.3.0/24 in the transit gateway route tables.

In Account A, recreate propagation for 10.0.0.0/16 in the transit gateway route tables.

Question # 74

A company has agreed to collaborate with a partner for a research project. The company has multiple VPCs in the us-east-1 Region that use CIDR blocks within 10.10.0.0/16. The VPCs are connected by a transit gateway that is named TGW-C in us-east-1. TGW-C has an Autonomous System Number (ASN) configuration value of 64520.

The partner has multiple VPCs in us-east-1 that use CIDR blocks within 172.16.0.0/16. The VPCs are connected by a transit gateway that is named TGW-P in us-east-1. TGW-P has an ASN configuration value of 64530.

A network engineer needs to establish network connectivity between the company's VPCs and the partner's VPCs in us-east-1.

Which solution will meet these requirements with MINIMUM changes to both networks?

Create a new VPC in a new account. Deploy a router from AWS Marketplace. Share TGW-C and TGW-P with the new account by using AWS Resource Access Manager (AWS RAM). Associate TGW-C and TGW-P with the new VPC. Configure the router in the new VPC to route between TGW-C and TGW-P.

Create an IPsec VPN connection between TGW-C and TGW-P. Configure the routing between the transit gateways to use the IPsec VPN connection.

Question # 76

A logistics company has multiple VPCs in an AWS Region. The company uses a transit gateway to connect the VPCs. The company has several on-premises offices that connect to the transit gateway by using AWS Site-to-Site VPN connections over the internet. The company has configured one transit gateway VPN attachment for each office.

Route propagation is enabled on all route tables. Each Site-to-Site VPN connection uses two tunnels in an active-passive configuration. The company configured each office with appropriate static routes on both the Site-to-Site VPN connection and the officeâ€™s customer gateway.

The company wants to use both IPsec tunnels of every office to maximize the overall VPN connection bandwidth.

Which design changes are necessary to meet these requirements?

Create an AWS Transit Gateway Connect attachment for each office Use the existing VPN attachments as the transport for the new Connect attachments. Set up a Generic Routing

Encapsulation (GRE) tunnel on each customer gateway that terminates on the Connect attachment for each office. Move the static routes from the transit gateway VPN attachment to the customer gateway for the transit gateway Connect attachment.

Enable equal-cost multi-path (ECMP) routing on the transit gateway. Ensure ECMP is supported by and enabled on the customer gateways. Enable ECMP on the Site-to-Site VPN connection. Ensure static routes on the customer gateways have equal metrics and administrative distance.

Enable equal-cost multi-path (ECMP) routing on the transit gateway. (Ensure ECMP is supported by and enabled on the customer gateways. Change the routing configuration between the transit gateway and the customer gateways from static routing to BGP. Remove related static routes from the customer gateways.

Enable equal-cost multi-path (ECMP) routing on the transit gateway. Ensure ECMP is supported by and enabled on the customer gateways. Change the routing configuration between the transit gateway and the customer gateways from static routing to BGP. Ensure the customer gateway applies the correct community strings to give the transit gateway the ability to perform ECMP forwarding.

Question # 77

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?

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.

Question # 79

A network engineer needs to set up an Amazon EC2 Auto Scaling group to run a Linux-based network appliance in a highly available architecture. The network engineer is configuring the new launch template for the Auto Scaling group.

In addition to the primary network interface the network appliance requires a second network interface that will be used exclusively by the application to exchange traffic with hosts over the internet. The company has set up a Bring Your Own IP (BYOIP) pool that includes an Elastic IP address that should be used as the public IP address for the second network interface.

How can the network engineer implement the required architecture?

Configure the two network interfaces in the launch template. Define the primary network interface to be created in one of the private subnets. For the second network interface, select one of the public subnets. Choose the BYOIP pool ID as the source of public IP addresses.

Configure the primary network interface in a private subnet in the launch template. Use the user data option to run a cloud-init script after boot to attach the second network interface from a subnet with auto-assign public IP addressing enabled.

Create an AWS Lambda function to run as a lifecycle hook of the Auto Scaling group when an instance is launching. In the Lambda function, assign a network interface to an AWS Global Accelerator endpoint.

During creation of the Auto Scaling group, select subnets for the primary network interface. Use the user data option to run a cloud-init script to allocate a second network interface and to associate an Elastic IP address from the BYOIP pool.

Question # 80

A company uses AWS Network Firewall to protect outgoing traffic for multiple VPCs that are in the same AWS account. Each VPC contains Amazon EC2 instances that host the company's applications. Each EC2 instance is tagged with the name of the application it hosts. The EC2 instances are in Auto Scaling groups.

A Network Firewall stateful rule group must remain up-to-date, even when an Auto Scaling group launches and terminates EC2 instances.

Which solution will meet this requirement with the LEAST implementation and administrative effort?

Create a network ACL for each application. Reference the network ACL in the stateful rule group.

Create a prefix list for each application. Reference the prefix list in the stateful rule group.

Create an AWS Lambda function that queries the EC2 instance tags for each application name and then updates the stateful rule group with the IP address of each instance.

Create a resource group for each application name. Reference the Amazon Resource Name (ARN) for the resource groups in the stateful rule group.
