True or False: In certain situations, writing data directly to secondary member nodes is permissible.

The assertion is false because, in MongoDB's architecture, data can only be written to the primary member of a replica set. Secondary nodes are intended for redundancy and load balancing by handling read operations, but they replicate the changes made on the primary. This ensures data consistency and integrity across the database cluster. Allowing direct writes to secondary nodes would introduce complications with data synchronization and could result in conflicts, leading to potential data loss or corruption. Therefore, for maintaining the integrity of the database and ensuring that all nodes are consistently up to date with the same data, writing data should strictly be carried out on the primary node only. This design upholds the principles of MongoDB's replication and is crucial for the reliability of transactional operations within the database.
