AWS Certified Database – Specialty — Question 328

A database specialist wants to ensure that an Amazon Aurora DB cluster is always automatically upgraded to the most recent minor version available. Noticing that there is a new minor version available, the database specialist has issues an AWS CLI command to enable automatic minor version updates. The command runs successfully, but checking the Aurora DB cluster indicates that no update to the Aurora version has been made.
What might account for this? (Choose two.)

Answer options

• A. The new minor version has not yet been designated as preferred and requires a manual upgrade.
• B. Configuring automatic upgrades using the AWS CLI is not supported. This must be enabled expressly using the AWS Management Console.
• C. Applying minor version upgrades requires sufficient free space.
• D. The AWS CLI command did not include an apply-immediately parameter.
• E. Aurora has detected a breaking change in the new minor version and has automatically rejected the upgrade.

Correct answer: A, D

Explanation

Automatic minor version upgrades in Amazon Aurora only occur when a new minor version is officially designated as the preferred version by AWS. Additionally, modifications to the DB cluster configuration via the AWS CLI require the apply-immediately parameter if they are to take effect immediately, otherwise they are deferred until the next maintenance window.
