Which two statements correctly describe Spine-Leaf switch topologies? (Choose two.)
A.
Spine-leaf topologies must utilize layer 3 switching for inter-connectivity.
B.
Spine-leaf topologies can utilize layer 2 or layer 3 switching for inter-connectivity.
C.
Oversubscription, if it occurs, is more likely to be found in the spine switches.
D.
Oversubscription, if it occurs, is more likely to be found in the leaf switches.
A,D ?
Agreed, Correct answer should be A and D.
The spine switch has only interfaces that connect to leaf switches; all interfaces are configured as routed point-to-point
links, effectively acting as the “other end” of the leaf switch’s point-to-point uplinks.
In spine–leaf switch topologies, oversubscription typically occurs—if at all—at one point: the leaf switch.
TRILL is a spine leaf protocol that operates @ L2. There are other derivitives of this
Yes to B: http://searchdatacenter.techtarget.com/feature/Data-center-network-design-moves-from-tree-to-leaf
“Leaf-spine architectures can be layer 2 or layer 3, meaning that the links between the leaf and spine layer could be either switched or routed.”
D should also be correct.
