1. Which of the following must exist to ensure the viability of a duplicate information processing facility?
A) The site is near the primary site to ensure quick and efficient recovery.
B) The site contains the most advanced hardware available.
C) The workload of the primary site is monitored to ensure adequate backup is available.
D) The hardware is tested when it is installed to ensure it is working properly.
2. An offsite information processing facility with electrical wiring, air conditioning and flooring, but no computer or communications equipment, is a:
A) cold site.
B) warm site.
C) dial-up site.
D) duplicate processing facility.
3. A disaster recovery plan for an organization should:
A) reduce the length of the recovery time and the cost of recovery.
B) increase the length of the recovery time and the cost of recovery.
C) reduce the duration of the recovery time and increase the cost of recovery.
D) affect neither the recovery time nor the cost of recovery.
4. A disaster recovery plan for an organization's financial system specifies that the recovery point objective (RPO) is no data loss and the recovery time objective(RTO) is 72 hours. Which of the following is the MOST cost-effective solution?
A) A hot site that can be operational in eight hours with asynchronous backup of the transaction logs
B) Distributed database systems in multiple locations updated asynchronously
C) Synchronous updates of the data and standby active systems in a hot site
D) Synchronous remote copy of the data in a warm site that can be operational in 48 hours

1. Right Answer: C
Explanation: Resource availability must be assured. The workload of the site must be monitored to ensure that availability for emergency backup use is not impaired. The site chosen should not be subject to the same natural disaster as the primary site. In addition, a reasonable compatibility of hardware/software must exist to serve as a basis for backup. The latest or newest hardware may not adequately serve this need. Testing the hardware when the site is established is essential, but regular testing of the actual backup data is necessary to ensure the operation will continue to perform as planned.
2. Right Answer: A
Explanation: A cold site is ready to receive equipment but does not offer any components at the site in advance of the need. A warm site is an offsite backup facility that is partially configured with network connections and selected peripheral equipment-such as disk and tape units, controllers and CPUs-to operate an information processing facility. A duplicate information processing facility is a dedicated, self-developed recovery site that can back up critical applications.
3. Right Answer: A
Explanation: One of the objectives of a disaster recovery plan is to reduce the duration and cost of recovering from a disaster. A disaster recovery plan would increase the cost of operations before and after the disaster occurs, but should reduce the time to return to normal operations and the cost that could result from a disaster.
4. Right Answer: D
Explanation: The synchronous copy of the storage achieves the RPO objective and a warm site operational in 48 hours meets the required RTO. Asynchronous updates of the database in distributed locations do not meet the RPO. Synchronous updates of the data and standby active systems in a hot site meet the RPO and RTO requirements but are more costly than a warm site solution.
5. Right Answer: C
Explanation: The unavailability of the central communications processor would disrupt all access to the banking network. This could be caused by an equipment, power or communications failure. Reciprocal agreements make an organization dependent on the other organization and raise privacy, competition and regulatory issues.Having an alternate processor in the same location resolves the equipment problem, but would not be effective if the failure was caused by environmental conditions (i.e., power disruption). The installation of duplex communication links would only be appropriate if the failure were limited to the communication link.
