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 is one restriction: The synchronization network must guarantee no more than 100
ms latency.
B.
There is one restriction: The synchronization network must guarantee no more than 150
ms latency (ITU Standard G.114).
C.
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.
D.
There are no restrictions.
