Which command is used to determine storage capacity of specific database?

Question

Options

• Amongotop
• Bdbstats
• Cmongostat
• Dconstats

• A
  3% (1)
• B
  87% (26)
• C
  7% (2)
• D
  3% (1)

Explanation

db.stats() (the dbstats command) returns detailed statistics about a specific database, including storage size, data size, number of collections, and index sizes - making it the correct tool for assessing storage capacity at the database level.

Why the distractors are wrong:

• A. mongotop - tracks read/write activity (time spent per collection), not storage capacity.
• C. mongostat - provides a real-time snapshot of a running mongod instance's throughput and operations, not database-level storage details.
• D. constats - not a valid MongoDB command.

Memory tip: Think "dbstats = dbatabase statistics" - it's scoped to a single database and tells you how much space that database is consuming, just like checking the size of a specific folder on your hard drive.
