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

Explanation:
Having an alternative standby processor at another network node would be the best solution. 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 in the case of a power outage, installation of duplex
communication links would be most appropriate if it were only the communication link that failed.
