Final answer:
It is best practice to create a backup of the AD RMS configuration immediately after installation due to the complex nature of the system. Correct answer is (D).
Step-by-step explanation:
After the installation of an Active Directory Rights Management Services (AD RMS) configuration, it is best practice to create a backup of the configuration. AD RMS is a server software for information protection which uses encryption and a form of digital rights management to protect sensitive data.
The complexity of an AD RMS environment is due to the various components like the database, server, and the trusted publishing domain that it involves.
Backing up the configuration means saving all the information related to the AD RMS server's setup, including the configuration database, server licensor certificate, private key, and any other important data associated with the trust hierarchy.
This is crucial as it ensures that you can restore the system to a working state in case of system failure, data corruption, or any other unforeseen scenarios that might disrupt the AD RMS services. Having a backup allows the quick recovery of every aspect of AD RMS without the need to set up everything from scratch, which can be time-consuming and error-prone.
