sensitive data that must be retained for a long period of time due to regulatory requirements? A. Full backup window B. Media costs C. Restore window D. Media reliability Answer: D Isaca CISA: Practice Exam "Pass Any Exam. Any Time." - 423
ActualTests.com Explanation: To comply with regulatory requirements, the media should be reliable enough to ensure an organization's ability to recovery the data should they be required for any reason. Media price is a consideration, but should not be more important than the ability to provide the required reliability. Choices A and C are less critical than reliability. QUESTION NO: 946 In the event of a data center disaster, which of the following would be the MOST appropriate strategy to enable a complete recovery of a critical database? A. Daily data backup to tape and storage at a remote site B. Real-time replication to a remote site C. Hard disk mirroring to a local server D. Real-time data backup to the local storage area network (SAN) Answer: B Explanation: With real-time replication to a remote site, data are updated simultaneously in two separate locations; therefore, a disaster in one site would not damage the information located in the remote site. This assumes that both sites were not affected by the disaster. Daily tape backup recovery could lose up to a day's work of datA . Choices C and D take place in the same data center and could possibly be affected by the same disaster. QUESTION NO: 947 Which of the following backup techniques is the MOST appropriate when an organization requires extremely granular data restore points, as defined in the recovery point objective (RPO)? A. Virtual tape libraries B. Disk-based snapshots C. Continuous data backup D. Disk-to-tape backup Answer: C Explanation: The recovery point objective (RPO) is based on the acceptable data loss in the case of a disruption. In this scenario the organization needs a short RPO. Virtual tape libraries, disk-based snapshots and disk-to-tape backup would require time to complete the backup, while continuous data backup happens online (in real time).

ActualTests.com QUESTION NO: 948 What is the BEST backup strategy for a large database with data supporting online sales? A. Weekly full backup with daily incremental backup B. Daily full backup C. Clustered servers D. Mirrored hard disks Answer: A Explanation: Weekly full backup and daily incremental backup is the best backup strategy; it ensures the ability to recover the database and yet reduces the daily backup time requirements. A full backup normally requires a couple of hours, and therefore it can beimpractical to conduct a full backup every day. Clustered servers provide a redundant processing capability, but are not a backup. Mirrored hard disks will not help in case of disaster.
