AWS Certified Advanced Networking- Specialty Questions and Answers

Question 13

A company is deploying a new application in the AWS Cloud. The company wants a highly available web server that will sit behind an Elastic Load Balancer. The load balancer will route requests to multiple target groups based on the URL in the request. All traffic must use HTTPS. TLS processing must be offloaded to the load balancer. The web server must know the user’s IP address so that the company can keep accurate logs for security purposes.

Which solution will meet these requirements?

Options:

A.

Deploy an Application Load Balancer with an HTTPS listener. Use path-based routing rules to forward the traffic to the correct target group. Include the X-Forwarded-For request header with traffic to the targets.

B.

Deploy an Application Load Balancer with an HTTPS listener for each domain. Use host-based routing rules to forward the traffic to the correct target group for each domain. Include the X-Forwarded-For request header with traffic to the targets.

C.

Deploy a Network Load Balancer with a TLS listener. Use path-based routing rules to forward the traffic to the correct target group. Configure client IP address preservation for traffic to the targets.

D.

Deploy a Network Load Balancer with a TLS listener for each domain. Use host-based routing rules to forward the traffic to the correct target group for each domain. Configure client IP address preservation for traffic to the targets.

Question 14

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:

A.

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.

B.

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.

C.

Configure the ALB in a public subnet of the VPAttach an internet gateway. Add 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 accelerator's IP addresses on the ALB listener port.

D.

Configure the ALB in a private subnet of the VPC. Attach an internet gateway. Add 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 accelerator's IP addresses on the ALB listener port.

Question 15

A company has its production VPC (VPC-A) in the eu-west-1 Region in Account 1. VPC-A is attached to a transit gateway (TGW-A) that is connected to an on-premises data center in Dublin, Ireland, by an AWS Direct Connect transit VIF that is configured for an AWS Direct Connect gateway. The company also has a staging VPC (VPC-B) that is attached to another transit gateway (TGW-B) in the eu-west-2 Region in Account 2.

A network engineer must implement connectivity between VPC-B and the on-premises data center in Dublin.

Which solutions will meet these requirements? (Choose two.)

Options:

A.

Configure inter-Region VPC peering between VPC-A and VPC-B. Add the required VPC peering routes. Add the VPC-B CIDR block in the allowed prefixes on the Direct Connect gateway association.

B.

Associate TGW-B with the Direct Connect gateway. Advertise the VPC-B CIDR block under the allowed prefixes.

C.

Configure another transit VIF on the Direct Connect connection and associate TGW-B. Advertise the VPC-B CIDR block under the allowed prefixes.

D.

Configure inter-Region transit gateway peering between TGW-A and TGW-B. Add the peering routes in the transit gateway route tables. Add both the VPC-A and the VPC-B CIDR block under the allowed prefix list in the Direct Connect gateway association.

E.

Configure an AWS Site-to-Site VPN connection over the transit VIF to TGW-B as a VPN attachment.

Question 16

A Network Engineer is provisioning a subnet for a load balancer that will sit in front of a fleet of application servers in a private subnet. There is limited IP space left in the VPC CIDR. The application has few users now but is expected to grow quickly to millions of users.

What design will use the LEAST amount of IP space, while allowing for this growth?

Options:

A.

Use two /29 subnets for an Application Load Balancer in different Availability Zones.

B.

Use one /29 subnet for the Network Load Balancer. Add another VPC CIDR to the VPC to allow for future growth.

C.

Use two /28 subnets for a Network Load Balancer in different Availability Zones.

D.

Use one /28 subnet for an Application Load Balancer. Add another VPC CIDR to the VPC to allow for future growth.
