AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 77

A company has an application running in an Amazon VPC that must be able to communicate with on-premises resources in a data center. Network traffic between
AWS and the data center will initially be minimal, but will increase to more than 10 Gbps over the next few months. The company's goal is to launch the application as quickly as possible.
The network engineer has been asked to design a hybrid IT connectivity solution.
What should be done to meet these requirements?

Answer options

• A. Submit a 1 Gbps AWS Direct Connect connection request, then increase the number of Direct Connect connections, as needed.
• B. Allocate elastic IPs to Amazon EC2 instances for temporary access to on-premises resources, then provision AWS VPN connections between an Amazon VPC and the data center.
• C. Provision an AWS VPN connection between an Amazon VPC and the data center, then submit an AWS Direct Connect connection request. Later, cut over from the VPN connection to one or more Direct Connect connections, as needed.
• D. Provision a 100 Mbps AWS Direct Connect connection between an Amazon VPC and the data center, then submit a Direct Connect connection request. Later, cut over from the hosted connection to one or more Direct Connect connections, as needed.

Correct answer: C

Explanation

Option C is correct because it allows for immediate connectivity through the AWS VPN while planning for the higher bandwidth requirements with AWS Direct Connect. This approach ensures that the application can be launched quickly with the VPN, and later transitioned to Direct Connect as traffic increases. The other options either do not provide a sufficient immediate solution or are not scalable for future bandwidth needs.
