A network architect must redesign a service provider edge, where multiservice and multitenant PEs are currently present. Which design feature should be minimized in the new design to achieve reliability?
"Fate sharing" refers to multiple services or customers relying on the same physical or logical component. Minimizing fate sharing improves reliability by isolating failures:
Isolating customer services ensures that failure in one domain does not affect others.
Separating critical control and data planes enhances resiliency.
Why other options are incorrect:
A: Bridging may introduce other issues but is not directly tied to fate sharing.
C: Redundancy enhances, not reduces, reliability.
D: Unicast overlay routing is not a fault domain problem in this context.
