Exam NCP-DB Topic 1 Question 61 Discussion

Actual exam question for Nutanix's NCP-DB exam
Question #: 61
Topic #: 1
What happens to the primary member in a MongoDB Server Cluster during the NDB patching process?

Suggested Answer: D Vote an answer

According to the NDB documentation, the NDB patching process for MongoDB Server Cluster follows these steps1:
* NDB identifies the primary member of the MongoDB Server Cluster and patches it first.
* NDB triggers a failover to elect a new primary member from the remaining secondary members.
* NDB patches the former primary member, which becomes a secondary member after the failover.
* NDB patches the remaining secondary members one by one.
* NDB verifies the patching status and the cluster health.
This process ensures that the MongoDB Server Cluster always has a primary member available to handle write operations, while minimizing the downtime and the impact on the cluster performance.
