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 no restrictions.
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 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.
