The CIO has mandated that the application be moved to the cloud to avoid further disruptions, with the additional requirement that source IP addresses be unaltered to support network traffic-monitoring needs. Which of the following designs will meet these requirements?

A : Use an Auto Scaling group of Amazon EC2 instances behind a Classic Load Balancer.

B : Use an Auto Scaling group of EC2 instances in a target group behind an Application Load Balancer.

C : Use an Auto Scaling group of EC2 instances in a target group behind a Classic Load Balancer.

D : Use an Auto Scaling group of EC2 instances in a target group behind a Network Load Balancer.

Answer: D

Question 2

A company is deploying a non-web application on an AWS load balancer. All targets are servers located on-premises that can be accessed by using AWS Direct Connect. The company wants to ensure that the source IP addresses of clients connecting to the application are passed all the way to the end server.

How can this requirement be achieved?

A : Use a Network Load Balancer to automatically preserve the source IP address.

B : Use a Network Load Balancer and enable the X-Forwarded-For attribute.

C : Use a Network Load Balancer and enable the ProxyProtocol v2 attribute.

Question 4

A department in your company has created a new account that is not part of the organization's consolidated billing family. The department has also created a VPC for its workload. Access is restricted by network access control lists to the department's on-premises private IP allocation. An AWS Direct Connect private virtual interface for this VPC advertises a default route to the company network. When the department downloads data from an Amazon Elastic Compute Cloud(EC2) instance in its new VPC, what are the associated charges?

A : The company pays Internet Data Out charges.

B : The company pays AWS Direct Connect Data Out charges.

C : The department pays Internet Data Out charges.

D : The department pays AWS Direct Connect Data Out charges.

Answer: D

Question 5

Your company has set up AWS Direct Connect to connect on-premises to an Amazon VPC instance. Two Direct Connect connections terminate at two different Direct Connect locations. You are using two routers, R1 and R2, at your end (one of each Direct Connect connection). R1 and R2 do NOT have connectivity between them. Both routers advertise the same routers over BGP to the VGW. You have a stateful firewall on each router. The routers drop some of the traffic coming from the VPC.

Which two actions should you take to fix this problem? (Select two.)

A : Use BGP AS prepend attribute to prepend additional AS numbers while advertising routers from R1 to VGW.

B : Use BGP local preference attribute to assign R1 to a lower local preference number than R2.

C : Use BGP local preference attribute to assign R1 a higher local preference number than R2.

D : Use BGP MED attribute to assign a higher MED value to the routes advertised R1 to VGW.

E : Use BGP MED attribute to assign a higher MED value to the routes advertised from R2 to VGW.

Answer: A,D
