Amazon AWS Certified Advanced Networking - Specialty Questions and Answers

Question 25

A company has a VPC in the AWS Cloud. The company recently acquired a competitor that also has a VPC in the AWS Cloud. A network engineer discovers an IP address overlap between the two VPCs. Both VPCs require access to an AWS Marketplace partner service.

Which solution will ensure interoperability among the VPC hosted services and the AWS Marketplace partner service?

Options:

A.

Configure VPC peering with static routing between the VPCs. Configure an AWS Site-to-Site VPN connection with static routing to the partner service.

B.

Configure a NAT gateway in the VPCs. Configure default routes in each VPC to point to the local NAT gateway. Attach each NAT gateway to a transit gateway. Configure an AWS Site-to-Site VPN connection with static routing to the partner service.

C.

Configure AWS PrivateLink to facilitate connectivity between the VPCs and the partner service. Use the DNS name that is created with the associated interface endpoints to route traffic between the VPCs and the partner service.

D.

Configure a NAT instance in the VPCs. Configure default routes in each VPC to point to the local NAT instance. Configure an interface endpoint in each VPC to connect to the partner service. Use the DNS name that is created with the associated interface endpoints to route traffic between the VPCs and the partner service.

Question 26

An online retail company is running a web application in the us-west-2 Region and serves consumers in the United States. The company plans to expand across several countries in Europe and wants to provide low latency for all its users.

The application needs to identify the users' IP addresses and provide localized content based on the users' geographic location. The application uses HTTP GET and POST methods for its functionality. The company also needs to develop a failover mechanism that works for GET and POST methods and is based on health checks. The failover must occur in less than 1 minute for all clients.

Which solution will meet these requirements?

Options:

A.

Configure a Network Load Balancer (NLB) for the application in each environment In the new AWS Regions. Create an AWS Global Accelerator accelerator that has endpoint groups that point to the NLBs in each Region.

B.

Configure an Application Load Balancer (ALB) for the application in each environment in the new AWS Regions. Create an AWS Global Accelerator accelerator that has endpoint groups that point to the ALBs in each Region.

C.

Configure an Application Load Balancer (ALB) for the application in each environment in the new AWS Regions. Create Amazon Route 53 public hosted zones that have failover routing policies.

D.

Configure a Network Load Balancer (NLB) for the application in each environment in the new AWS Regions. Create an Amazon CloudFront distribution. Configure an origin group with origin failover options.

Question 27

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?

Options:

A.

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.

B.

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.

C.

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.

D.

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 28

A company is deploying an application. The application is implemented in a series of containers in an Amazon Elastic Container Service (Amazon ECS) cluster. The company will use the Fargate launch type for its tasks. The containers will run workloads that require connectivity initiated over an SSL connection. Traffic must be able to flow to the application from other AWS accounts over private connectivity. The application must scale in a manageable way as more consumers use the application.

Which solution will meet these requirements?

Options:

A.

Choose a Gateway Load Balancer (GLB) as the type of load balancer for the ECS service. Create a lifecycle hook to add new tasks to the target group from Amazon ECS as required to handle scaling. Specify the GLB in the service definition. Create a VPC peer for external AWS accounts. Update the route tables so that the AWS accounts can reach the GLB.

B.

Choose an Application Load Balancer (ALB) as the type of load balancer for the ECS service. Create path-based routing rules to allow the application to target the containers that are registered in the target group. Specify the ALB in the service definition. Create a VPC endpoint service for the ALB Share the VPC endpoint service with other AWS accounts.

C.

Choose an Application Load Balancer (ALB) as the type of load balancer for the ECS service. Create path-based routing rules to allow the application to target the containers that are registered in the target group. Specify the ALB in the service definition. Create a VPC peer for the external AWS accounts. Update the route tables so that the AWS accounts can reach the ALB.

D.

Choose a Network Load Balancer (NLB) as the type of load balancer for the ECS service. Specify the NLB in the service definition. Create a VPC endpoint service for the NLB. Share the VPC endpoint service with other AWS accounts.
