When a data center is attempting to restore computing facilities at an alternative site following a disaster, which of the following should be restored FIRST?
When a data center is attempting to restore computing facilities at an alternative site following a disaster, which of the following should be restored FIRST?
When restoring computing facilities at an alternative site after a disaster, the first priority should be to restore the operating system. The operating system forms the fundamental layer of the computing environment and is essential to run any applications and manage the data backups. Without a functioning operating system, it is impossible to access or restore data backups properly or to run any necessary applications. Therefore, starting with the operating system provides a stable foundation for subsequent recovery steps.
Given these considerations, the first component to restore should be A. Operating System. This is because the operating system forms the basic layer of the computing environment, enabling the restoration and functioning of all other components, including applications and data backups. Once the operating system is in place, data backups can be restored, and applications necessary for critical business operations can be set up and configured.
Logically OS should come first how can you access data without interaction. Depending on the type of site we can choose what do we need first. Here is not saying anything about that so we should believe that OS will come first.
Data backups (B): Data is usually the most critical asset for an organization. Therefore, restoring data backups is often the first step in disaster recovery. This ensures that important data is available for use as soon as possible. Operating system (A): Once data is restored, the next priority is to bring up the operating system. The operating system is necessary to run applications and provide a platform for other services. Applications (D): After the operating system is in place, applications can be restored. This includes essential business applications that the organization relies on to function. Decision support system (C): Decision support systems, while important, are typically of lower priority compared to data, operating systems, and essential applications. They can be restored after the core infrastructure and critical applications are up and running.
Depending on whether the alternate site is a warm or cold site, the alternate site is usually focused on returning backups, not on doing things like restoring from the OS.
Answer A the Question is about "attempting to restore computing facilities at an alternative site following a disaster" not the data
A. Operating system
I'm pretty sure that backups do NOT come before OS.
