Answers
Suggested answer: A

Explanation:

Nutanix Database Service (NDB) supports automated minor version upgrades for PostgreSQL1.Before applying the patch, the administrator should create a new software profile2.This is because the software profile contains the database engine binaries and other software required to run the database engine2.Therefore, to apply a minor version upgrade, a new software profile with the updated binaries needs to be created2.Once the new software profile is created, it can be used to patch the PostgreSQL database2.
