A solutions architect is developing a multiple-subnet VPC architecture. The solution will consist of six subnets in two Availability Zones. The subnets are defined as public, private and dedicated for databases. Only the Amazon EC2 instances running in the private subnets should be able to access a database. Which solution meets these requirements?
A company creates operations data and stores the data in an Amazon S3 bucket for the company's annual audit, an external consultant needs to access an annual report that is stored in the S3 bucket.

Answers
D.
Create a Route 53 public hosted zone. Create a record for each service to allow service communication.
Suggested answer: A

Explanation:

To meet the requirements of the web application in the most secure manner, the company should create a Route 53 Resolver outbound endpoint, create a resolver rule, and associate the resolver rule with the VPC. This solution will allow the application to use private DNS records to communicate with the on-premises services from a VPC. Route 53 Resolver is a service that enables DNS resolution between on-premises networks and AWS VPCs. An outbound endpoint is a set of IP addresses that Resolver uses to forward DNS queries from a VPC to resolvers on an on-premises network. A resolver rule is a rule that specifies the domain names for which Resolver forwards DNS queries to the IP addresses that you specify in the rule.By creating an outbound endpoint and a resolver rule, and associating them with the VPC, the company can securely resolve DNS queries for the on-premises services using private DNS records12.

The other options are not correct because they do not meet the requirements or are not secure. Creating a Route 53 Resolver inbound endpoint, creating a resolver rule, and associating the resolver rule with the VPC is not correct because this solution will allow DNS queries from on-premises networks to access resources in a VPC, not vice versa.An inbound endpoint is a set of IP addresses that Resolver uses to receive DNS queries from resolvers on an on-premises network1. Creating a Route 53 private hosted zone and associating it with the VPC is not correct because this solution will only allow DNS resolution for resources within the VPC or other VPCs that are associated with the same hosted zone.A private hosted zone is a container for DNS records that are only accessible from one or more VPCs3. Creating a Route 53 public hosted zone and creating a record for each service to allow service communication is not correct because this solution will expose the on-premises services to the public internet, which is not secure.A public hosted zone is a container for DNS records that are accessible from anywhere on the internet3.
