One strategy for implementing server recovery and redundancy through mirroring servers uses hot, warm, and cold servers. Explain how this strategy works.
What will be an ideal response?
In this strategy, the online primary server is the hot server, and it provides the services necessary to support operations. The warm server serves as an ancillary or secondary server, and it services requests when the primary is busy or down. The cold server is the administrator's test platform and should be identically configured to the hot and warm servers. Before a patch, upgrade, or new application is applied to the hot and warm servers, it is first tested on the cold server. Should the hot server go down, the warm server automatically takes over as the hot server, and the cold server can be added as the new warm server while the hot server is taken offline for repair.
