Read/Writes Operation Guarantees - Quiz has inaccurate solution

The option “The write concern tells which server to write data to” is considered incorrect by the grader, however, in the documentation it is stated that you can use a “tagged member” to specify the members to propagate the write operation.

Is my understanding correct?

Hi @Michael_Moraes_Capela,
As per MongoDB’s Documentation:

Write concern describes the level of acknowledgment requested from MongoDB for write operations to a standalone mongod or to replica sets or to sharded clusters.

Therefore, it does not explicitly tells which server to write data to, it just ensures the level acknowledgment.

If you have any doubts, please feel free to reach out to us.

Thanks and Regards.
