A hospital runs live electronic records in one data center. A second data center has the systems ready and does not serve users until the first site fails. Which pattern is this?
Select an answer to reveal the explanation.
Short Explanation
You have one kitchen cooking and another kitchen preheated and empty of customers. That waiting kitchen is active-passive. If both kitchens were serving meals you would call both active, and an empty room with no stoves, or a meeting about a flood, is not this hospital's second site.
Full Explanation
Active-passive keeps one site serving users and holds the other ready to take over. The hospital's records run in one data center, and the second site does not serve users until the first fails, so the pattern is active-passive. Active-active serves users from both sites at once. The waiting site is not serving users, so the distractor contradicts the stem. A cold site does not have systems ready. It is space and power, and this second data center already has the systems. A tabletop exercise is a discussion. A data center with ready systems is not a meeting. Exam caveat: the passive site is only as current as its replication. A long replication lag becomes data loss when you fail over. Operational check: confirm the passive site is receiving replication, fail over in a test window, and confirm users are served from the second site only after the test starts. During a test window, fail over and confirm users land on the second site only after the test starts. Measure how old the replicated data is before the test, so the failover does not surprise the hospital with a long gap.
