An organization’s corporate and 15 regional offices are between 1,000 – 2,000 kilometers apart
from each other. Each regional office has a data center that serves between four to six branch
offices that are located approximately 30 – 200 kilometers away.
At the close of business each evening, the organization shuts down their primary application and
transmits new information to each regional office. The amount of new information sent from
corporate headquarters each night is around 1.5 GB. Later each night, the application at the
regional offices reads the data and generates approximately 50 MB of new information appropriate
to the branch offices.
What is the most cost-effective solution you would recommend for the organization?

A.
Use Open Replicator’s incremental update for data transfer to each regional office.
Create a snap of the data at the regional offices and transmit the changes to the branch offices
using Open Replicator.

B.
Use SRDF/S for data transfer to each regional office.
Create snapshots of the mirror at the regional offices and transmit the changes to the branch
offices using Open Replicator.

C.
Use SRDF/A between the corporate and regional offices for data transfer to each regional
office.
Use Open Replicator’s incremental update to distribute information to the branch offices.

D.
Use SRDF/Star for all data transfers to the regional offices.
Use SRDF/A for data transfers between the regional and branch offices.
