A large chain of shops with EFT at point-of-sale devices has
a central communications processor for connecting to the
banking network. Which of the following is the BEST disaster
recovery plan for the communications processor?
A. Offsite storage of daily backups
B. Alternative standby processor onsite
C. Installation of duplex communication links
D. Alternative standby processor at another network node
Answer / guest
Answer: D
Having an alternative standby processor at another network
node would be the best. The unavailability of the central
communications processor would disrupt all access to the
banking network resulting in the disruption of operations
for all of the shops. This could be caused by failure of
equipment, power or communications. Offsite storage of
backups would not help since EFT tends to be an online
process and offsite storage will not replace the
dysfunctional processor. The provision of an alternate
processor onsite would be fine if it were an equipment
problem, but would not help if the outage were caused by
power, for example. Installation of duplex communication
links would be most appropriate if it were only the
communication link that failed.
