Peter, the system administrator, is performing an overnight system refresh of hundreds of user computers. The refresh has a strict timeframe and must have zero downtime during business hours. Which of the following should Peter take into consideration?
A. A disk-based image of every computer as they are being replaced. B. A plan that skips every other replaced computer to limit the area of affected users. C. An offsite contingency server farm that can act as a warm site should any issues appear. D. A back-out strategy planned out anticipating any unforeseen problems that may arise.
Explanation: A backout is a reversion from a change that had negative consequences. It could be, for example, that everything was working fine until you installed a service pack on a production machine, and then services that were normally available were no longer accessible. The backout, in this instance, would revert the system to the state that it was in before the service pack was applied. Backout plans can include uninstalling service packs, hotfixes, and patches, but they can also include reversing a migration and using previous firmware. A key component to creating such a plan is identifying what events will trigger your implementing the backout.
A security engineer is given new application extensions each month that need to be secured prior to implementation.

A. Patch Audit Policy B. Change Control Policy C. Incident Management Policy D. Regression Testing Policy E. Escalation Policy F. Application Audit Policy
Explanation: A backout (regression testing) is a reversion from a change that had negative consequences. It could be, for example, that everything was working fi ne until you installed a service pack on a production machine, and then services that were normally available were no longer accessible. The backout, in this instance, would revert the system to the state that it was in before the service pack was applied. Backout plans can include uninstalling service packs, hotfi xes, and patches, but they can also include reversing a migration and using previous firmware. A key component to creating such a plan is identifying what events will trigger your implementing the backout. A change control policy refers to the structured approach that is followed to secure a company’s assets in the event of changes occurring.
