I have managed to complete the lab BUT could not understand why there were some ‘missing’ steps not detailed in activities.
I changed mongos.conf THEN I was expecting to change the shard1 27001/27002/27003 to include something similar to…
I connected to 27001 and ran rs.conf() but could not see this [or something similar] in returned output. So I ‘skipped’ this step and added shard1 via mongos, ran tests and all passed
Question: Why did we not need to change conf for 27001/2/3?
