Organizations are sometimes faced with the need to locate cluster members in different
geographic locations that are distant from each other. A typical example is replicated data centers
whose location is widely separated for disaster recovery purposes. What are the restrictions of
this solution?
A.
There are two restrictions: 1. The synchronization network must guarantee no more than
100ms latency and no more than 5% packet loss. 2. The synchronization network may only
include switches and hubs.
B.
There is one restriction: The synchronization network must guarantee no more than 150 ms
latency (ITU Standard G.114).
C.
There is one restriction: The synchronization network must guarantee no more than 100 ms
latency.
D.
There are no restrictions.
