You are in a sharded cluster. What will you do prior to initiating backup in sharded cluster?

Question

Options

• Adb.stopBalancer()
• Bdb.stopserver()
• Csh.stopBalancer()
• Dsh.stopserverQ

• B
  4% (1)
• C
  92% (24)
• D
  4% (1)

Explanation

sh.stopBalancer() is correct because in MongoDB, sh is the shell helper object for sharding operations, and stopBalancer() is the proper method to halt the balancer process before taking a consistent backup - preventing chunk migrations from occurring mid-backup and causing data inconsistencies across shards.

Why the distractors are wrong:

• A (db.stopBalancer()) - db is the database helper object; it has no stopBalancer() method. This command will throw an error.
• B (db.stopserver()) - db doesn't have a stopserver() method either, and stopping the server entirely would defeat the purpose of taking a live backup.
• D (sh.stopserverQ) - sh is the correct object, but stopserverQ is not a real MongoDB method (it appears to be a fabricated distractor mixing server-stop terminology with a typo).

Memory tip: Think "sh = sharding" - anything related to shard-level cluster management uses the sh helper. Since the balancer is a sharding feature, pair it with sh: sh.stopBalancer().
