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.
