Question 30

A company has 10 web server Amazon EC2 instances that run in an Auto Scaling group in a production VPC. The company has 10 other web servers that run in an on-premises data center. The company has a 10 Gbps AWS Direct Connect connection between the on-premises data center and the production VPC.

The company needs to implement a load balancing solution that receives HTTPS traffic from thousands of external users. The solution must distribute the traffic across the web servers on AWS and the web servers in the on-premises data center. Regardless of the location of the web servers, HTTPS requests must go to the same web server throughout the entire session.

Which solution will meet these requirements?

Options:

A.

Create a Network Load Balancer (NLB) in the production VPC. Create a target group. Specify ip as the target type. Register the EC2 instances and the on-premises servers with the target group Enable connection draining on the NLB

B.

Create an Application Load Balancer (ALB) in the production VPC. Create a target group Specify ip as the target type. Register the EC2 instances and the on-premises servers with the target group. Enable application-based session affinity (sticky sessions) on the ALB.

C.

Create a Network Load Balancer (NLB) in the production VPC. Create a target group. Specify instance as the target type. Register the EC2 instances and the on-premises servers with the target group. Enable session affinity (sticky sessions) on the NLB.

D.

Create an Application Load Balancer (ALB) in the production VPC. Create a target group. Specify instance as the target type Register the EC2 instances and the on-premises servers with the target group Enable application-based session affinity (sticky sessions) on the ALB.

Question 31

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.
