Q82 — AWS SAA-C03 Ch.12
Question 82 of 100 | ← Chapter 12
Q882. A company has primary and secondary data centers that are 500 miles (804.7 km) apart and interconnected with high-speed fiber-optic cable. The company needs a highly available and secure network connection between its data centers and a VPC on AWS for a mission-critical workload. A solutions architect must choose a connection solution that provides maximum resiliency.Which solution meets these requirements?
- A. Two AWS Direct Connect connections from the primary data center terminating at two Direct Connect locations on two separate devices
- B. A single AWS Direct Connect connection from each of the primary and secondary data centers terminating at one Direct Connect location on the same device
- C. Two AWS Direct Connect connections from each of the primary and secondary data centers terminating at two Direct Connect locations on two separate devices ✓
- D. A single AWS Direct Connect connection from each of the primary and secondary data centers terminating at one Direct Connect location on two separate devices
Correct Answer: C. Two AWS Direct Connect connections from each of the primary and secondary data centers terminating at two Direct Connect locations on two separate devices
Explanation
The solution that meets the requirement for a highly available and secure network connection between the company's primary and secondary data centers and a VPC on AWS for a mission-critical workload is option C: Two AWS Direct Connect connections from each of the primary and secondary data centers terminating at two Direct Connect locations on two separate devices.AWS Direct Connect is a network service that provides dedicated and private network connectivity between the company's on-premises data centers and AWS. It enables a more consistent and reliable network experience compared to internet-based connections.To achieve maximum resiliency and availability, it is recommended to have redundant connections from both the primary and secondary data centers. This ensures that if one connection or device fails, the other connection can still provide connectivity without interruption.By having two AWS Direct Connect connections from each data center terminating at two Direct Connect locations on two separate devices, the company achieves a highly available and resilient network connection. Even if one connection or device fails, the other connection can continue to provide connectivity, ensuring continuous access to the mission-critical workload in the VPC.Option A suggests having two AWS Direct Connect connections from the primary data center only. This does not provide redundancy for the secondary data center and may result in a single point of failure.Option B suggests having a single AWS Direct Connect connection from each data center terminating at one Direct Connect location on the same device. This configuration does not provide redundancy at the device level and may introduce a single point of failure.Option D suggests having a single AWS Direct Connect connection from each data center terminating at one Direct Connect location on two separate devices. While this provides some level of redundancy at the device level, it does not provide redundancy at the Direct Connect location level.In summary, the solution that meets the requirements for maximum resiliency is to have two AWS Direct Connect connections from each data center terminating at two Direct Connect locations on two separate devices (Option C).
