Amazon Exam ANS-C01 Topic 1 Question 25 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 25
Topic #: 1

A company is deploying a new stateless web application on AWS. The web application will run on Amazon EC2 instances in private subnets behind an Application Load Balancer. The EC2 instances are in an Auto Scaling group. The web application has a stateful management application for administration that will run on EC2 instances that are in a separate Auto Scaling group.

The company wants to access the management application by using the same URL as the web application, with a path prefix of /management. The protocol, hostname, and port number must be the same for the web application and the management application. Access to the management application must be restricted to the company's on-premises IP address space. An SSL/TLS certificate from AWS Certificate Manager (ACM) will protect the web application.

Which combination of steps should a network engineer take to meet these requirements? (Select TWO.)

AInsert a rule for the load balancer HTTPS listener. Configure the rule to check the path-pattern condition type for the /management prefix and to check the source-ip condition type for the on-premises IP address space. Forward requests to the management application target group if there is a match. Edit the management application target group and enable stickiness.

BModify the default rule for the load balancer HTTPS listener. Configure the rule to check the path-pattern condition type for the /management prefix and to check the source-Ip condition type for the on-premises IP address space. Forward requests to the management application target group if there is not a match. Enable group-level stickiness in the rule attributes.

CInsert a rule for the load balancer HTTPS listener. Configure the rule to check the path-pattern condition type for the /management prefix and to check the X-Forwarded-For HTTP header for the on-premises IP address space. Forward requests to the management application target group if there is a match. Enable group-level stickiness in the rule attributes.

DModify the default rule for the load balancer HTTPS listener. Configure the rule to check the path-pattern condition type for the /management prefix and to check the source-Ip condition type for the on-premises IP address space. Forward requests to the web application target group if there is not a match.

EForward all requests to the web application target group. Edit the web application target group and disable stickiness.

Show Suggested Answer

Suggested Answer: B

Creating a new Route 53 Resolver outbound endpoint in the shared services VPC would enable forwarding of DNS queries from the VPC to on-premises1.Creating forwarding rules for the on-premises hosted domains would enable specifying which domain names are forwarded to the on-premises DNS servers2.Associating the rules with the new Resolver endpoint and each application VPC would enable applying the rules to the VPCs2.This solution would not affect the default DNS resolution behavior of Route 53 Resolver for local VPC domain names and domains that are hosted in Route 53 private hosted zones3.
