Replication in MongoDB involves creating multiple copies of data across different servers, ensuring high availability and fault tolerance. It also involves setting up replica sets, managing primary and secondary nodes, and handling failover events to keep data accessible even during system failures.

This quiz is for database administrators and IT professionals managing high-availability systems who wish to test their ability to ensure data reliability, disaster recovery, and seamless failover in MongoDB environments.

Good luck!
