Not all data centers are created equal. The interviewer would like to see that you have a solid understanding of data centers and the differences between them.

- Tier 1 which is usually for small business, guaranteeing 99.671% availability.
- Tier 2 is best for medium-sized business, with 99.749% availability.
- Tier 3 offers 99.982% availability, making it an excellent option for large companies. These data centers can also sustain up to 72 hours of power outage.
- Tier 4 has sustainability up to 96 hours of a power outage, offers 99.995% availability, making it the best choice for enterprise businesses.

Explain to the interviewer how many data center tiers there are, and how they differ. Depending on the position for which you are interviewing, you may want to dig deeper into the technical differences between each.
