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.

Hi @MGHandy,

I faced the same struggle, and in the end came up with this, which passed validation:

The rule has no conditions, and applies to all fields. It works as intended, but I will say that the task is at best extremely poorly worded.

Thank you so much!
The wording for this task is just...bananas.

- 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

What???
We just need to add a reconciliation rule that:

• has 2 discovery sources (servicenow =100; LandDesk = 200), and
• apply to all attributes

That's it.

Hi @JanWinther 

Thank you for sharing the solution. It worked.

Thank @JanWinther , because the data source defines the source, there is no need to put in the filter condition.

Hi JanWinther,

I tried the solution you suggested but still, the task got validated. Thanks for the solution.
