Which data center characteristics should specifically make the architect consider switches that
support Shortest Path Bridging (SPB) or Transparent Interconnection of Lots of Links (TRILL)?
A.
The customer requires redundancy and resiliency for the two data center routing switches
B.
The customer requires high-speed routing between front-end servers and database servers in
different subnets
C.
The virtualized data center supports several thousand virtual machines (VMs) with a two-tier
networking infrastructure topology
D.
The data center requires many redundant links and must scale the tens of thousands of virtual
(VMs)
D is correct
Instead TRILL or SPBM, which are designed for load-sharing traffic over complex meshes of links, uses mechanisms based on the Intermediate System to Intermediate System (IS-IS) routing protocol to establish optimal shortest paths and distribution trees for broadcasts.
