Explanation
A is correct because ITAM integrates with business services via the Service Catalog from request through to disposal. This means that ITAM enables users to request, receive, track, and retire assets through a standardized and automated process. This also helps to optimize asset utilization and reduce costs12 B is correct because ITAM leverages ITSM to manage the lifecycle of assets as they pass through their useful life as CIs. This means that ITAM uses the same platform, data model, and architecture as ITSM to track and manage assets as they are deployed, maintained, upgraded, and disposed of. This also helps to improve service quality and availability, as well as compliance and security13 C is correct because ITAM provides input into, aligns with, and follows corporate governance. This means that ITAM helps to ensure that assets are accounted for, controlled, and protected according to the organization's policies, standards, and regulations. This also helps to mitigate risks, avoid fines, and support audits14 D is not correct because ITAM does not directly improve application privacy and security adherence.
This is more related to the function of IT Security Management, which is a separate module in ServiceNow. ITAM can support IT Security Management by providing accurate and up-to-date asset inventory and configuration data, but it does not enforce or monitor application privacy and security policies5 E is not correct because ITAM does not leverage Service Mapping to predict service impact. This is more related to the function of Service Mapping, which is another module in ServiceNow. Service Mapping creates a visual map of the relationships and dependencies between IT components and business services, and helps to identify and resolve service issues. ITAM can integrate with Service Mapping to provide asset data, but it does not use Service Mapping to predict service impact.

Explanation
According to the ServiceNow Hardware Asset Management overview document1, the total cost of ownership (TCO) of an asset is the sum of all direct and indirect costs incurred throughout its lifecycle, from acquisition to disposal1.
The original costs are the costs involved in purchasing an asset and putting it into use, such as lease, delivery, and spare parts12.
Lease is the cost of renting or leasing an asset from a vendor or a third party for a fixed period of time12. Lease costs can vary depending on the terms and conditions of the contract, such as duration, frequency, and interest rate2.
Delivery is the cost of transporting or shipping an asset from the vendor or the warehouse to the end user or the location where it will be used12. Delivery costs can include fees, taxes, customs, and insurance2.
Spare parts are the cost of purchasing or stocking additional or replacement parts for an asset in case of failure, damage, or wear and tear12. Spare parts costs can depend on the availability, quality, and compatibility of the parts2.
The other options are not original costs, but rather ongoing or disposal costs. Maintenance is the cost of repairing, servicing, or upgrading an asset to keep it in good working condition12. Storage is the cost of storing an asset that is not in use or waiting for disposal12.

Stock rules are a feature of ServiceNow Hardware Asset Management that allow you to automate the replenishment of stock levels in your stockrooms1.
Stock rules define the minimum and maximum quantities of a specific model that you want to keep in a stockroom, as well as the reorder point and quantity1.
When the stock level of a model falls below the reorder point, a stock order is automatically generated to replenish the stockroom to the maximum quantity1.
You can create and manage stock rules by navigating to Hardware Asset Management > Model Management > Stock Rules1. Reference:
