Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
az sql db resume --resource-group rg1 --server server1 --name db3
`az sql db resume` is the command to resume a paused database. Option A is wrong because `az sql db restart` restarts an online database but does not resume a paused one. Option C is wrong because `az sql db start` is not a valid command for Azure SQL Database. Option D is wrong because `az sql db update` can modify properties but cannot resume a paused database; resuming requires a dedicated command.
