In a collapsed core design, which three benefits are provided by a second-generation Cisco MDS
director? (Choose three.)
A.
a higher fan-out ratio
B.
fully redundant switches
C.
100 percent port efficiency
D.
all ISLs contained within a single chassis
E.
higher latency and throughput than a core-edge design switch
B
C
D
This
design reduces the number of ISLs required in the network so that all available ports can
be deployed for host or storage connections, leading to 100 percent port design efficiency.
In Figure 6-11, the backplane of the MDS in the collapsed-core design replaces all the
ISL links. This design can also provide a lower fan-out ratio than the multiple small
switches because the availability of more advanced blades for the MDS. Empty slots on
the MDS can support future growth on new line cards.
