CMDB Simulator Task 09: Configure Reconciliation Rule

[MGHandy]

I have been working through the self-paced CMDB Fundamentals course on NowLearning, I am stuck on the Configure the CMDB Simulator (Rome) > Task 09: Configure Reconciliation Rule.

It appears i may not be understanding something simple or there just isn't enough information given (which might be rather unlikely).

The requirement states:

Being part of the Cloud Dimensions CMDB implementation team, using CI Class Manager, you are tasked to update the Windows Server class with a reconciliation rule that achieves the following:

- Windows Server record in CMDB with discovery source LANDesk CAN be updated by discovery source ServiceNow

- Windows Server record in CMDB with discovery source ServiceNow CANNOT be updated by discovery source LANDesk

I have made rules where servicenow has priority over landesk to update all attributes where discovery source is servicenow OR landesk

I have created rules where landesk has priority over servicenow to update all attributes where discover source is NOT landsek.

I have taken each bullet above literally and made a rule specifically for what each says.

I have spent a total of almost three hours on this one simple little thing coming up with rules for everything in between and including the above. nothing appears to validate correctly. I don't know what i'm missing.

Can someone help me out. I don't necessarily want the answer, just help understanding what requirements are asking.

Rule 1: ServiceNow has priority over Landesk when the Discovery Source is ServiceNow OR Landesk.

Rule 2: Landesk has priority over ServiceNow when the Discovery Source is NOT Landesk.If both rules reference Landesk vs. NOT Landesk, there might be an overlap or unintended exclusions.Try modifying

Rule 2 to cover scenarios where Discovery Source is explicitly defined, instead of using "NOT Landesk.

Believe ServiceNow processes rules based on priority ranking. Ensure the rule you want to take precedence has a lower priority number (e.g., Rule 1: Priority 100, Rule 2: Priority 200)

I would check if any other active rules might be conflicting.

sorted this step due to CIS-FD, but clearly the wording of this step is confusing. 

also, I couldn't find in the documentation exact words how to NOT allow update..  why not to include this simple example into documentation and make everyone's life easier.

Keep both conditions in single rule.
