When connected to a MongoDB instance, mongodump can adversely affect ______ performance.

mdump
mongodump
mongod
All of the mentioned
To mitigate the impact of mongodump on the performance of the replica set, use mongodump to capture backups from a _________ member of a replica set.

primary
secondary

None of the mentioned
Point out the correct statement :

The mechanics of snapshots depend on the underlying storage system
To get a consistent snapshot of a sharded system, you must disable the balancer
If your storage system does not support snapshots, you can copy the files directly using cp, rsync, or a similar tool
All of the mentioned
Point out the wrong statement :

If you shut down a secondary to capture data with mongodump ensure that the operation can complete before its oplog becomes too stale to continue replicating
