ANS-C01Domain 1: Network DesignHybrid ConnectivityhardSingle choice

A financial firm's production workloads depend on Direct Connect to AWS. Leadership requires the hybrid link to survive any single facility or device failure. What's the resilient design?

A.One dedicated DX connection on a high-bandwidth port

A single connection is a single point of failure regardless of speed.

B.Two DX connections at separate locations/devices — plus a Site-to-Site VPN as backup path

Correct. Redundant DX + VPN backup is the reference resilient pattern.

C.A single DX connection with a higher SLA

SLAs are contractual, not technical redundancy.

D.Rely on the public internet for resilience

Public internet lacks the consistency/production guarantees needed.

Why this answer

DX resilience requires physically redundant connections at different colocation facilities/devices, ideally with a VPN backup path for worst-case dual failure. Bandwidth and SLAs don't create redundancy.
