Per AWS's maximum-resiliency guidance, a mission-critical hybrid link should tolerate device failure AND an entire Direct Connect location outage. What does that architecture require?
A.One DX connection with two VIFs
Two VIFs on one connection share every failure domain.
B.Two DX connections on separate devices at the same location
Device-failure tolerance but NOT location failure.
C.Two DX connections at two DIFFERENT DX locations
Correct. Location-level redundancy = max resiliency tier.
D.One DX plus a single VPN tunnel
VPN is a lower-tier backup, not 'maximum resiliency'.
Why this answer
AWS's resilience model: max resiliency = separate connections at separate DX locations (survives device failure, cable cuts, and full facility events). Same-location dual connections survive device failure only — a location outage kills both.
