Question

In order to recover from an attack on any one server, it would take an estimated 14 hours to rebuild servers 1, 2, 3, and 4 and 37 hours to rebuild server 5. If each server is required to be online 8,760 hours a year, compute the EF for each server.

Answer 1

It is an approximate time to rebuild servers to satisfy either ourselves or management.

Step-by-step explanation:

To rebuild the server all depends on CPU and process time taken by each individual server time taken.

Some servers to rebuild will take less time because the effected server is very less moreover some patches have to download from the internet and if downloading speed is very less then it will be a delay on the rebuild or recovering process. Suppose internet downloading speed fast enough but internal data operation speed is very low profile than their will in the delay to rebuild the servers.

Best practice method to restore from the last backup so the delay time to rebuild the server is known.
