A developer needs to manually trigger a full reindex of all indexers from the command line after a large data import. Which CLI command should be used?

Question

Options

• A'bin/magento indexer:reindex'
• B'bin/magento indexer:refresh'
• C'bin/magento indexer:run all'
• D'bin/magento indexer:update'

• A
  71% (24)
• B
  18% (6)
• C
  3% (1)
• D
  9% (3)

Explanation

bin/magento indexer:reindex is the correct command because it triggers a full reindex of all registered indexers in Magento 2, making it ideal after bulk data imports when the index is stale across the board. Option B (indexer:refresh) does not exist as a valid Magento CLI command. Option C (indexer:run all) is fabricated - while indexer:reindex can accept specific indexer IDs as arguments, there is no run subcommand. Option D (indexer:update) is similarly non-existent in the Magento CLI.

Memory tip: Think "R for Reindex, R for Real" - reindex is the real command. The others sound plausible but are invented. If you ever doubt it on the exam, recall that Magento CLI commands follow a noun:verb pattern, and reindex is the only valid verb here.
