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
SPB creates optimal unicast and multicast paths across large Layer 2 networks with many redundant links. It can also help to reduce the number of MAC addresses that switches in the large Layer 2 network must learn.
That’s mean SPB doesn’t support Layer3 but A choice said “two data center routing switches”
