According to the Audit your inventory document, a blind inventory audit is a type of audit that hides the expected asset list from the auditor, so that the auditor has to physically scan each asset in the location and compare it with the actual asset list1.
A blind inventory audit helps ensure data integrity and accuracy, as it prevents the auditor from
"cheating on the test" by relying on the expected asset list1.
A blind inventory audit is typically initiated via the Now Agent Mobile app, which is a mobile application that enables users to perform various tasks related to hardware asset management, such as scanning assets, creating audits, and viewing audit results1.
The Now Agent Mobile app allows users to create an audit on the mobile device, select the location and type of audit, and scan the assets using the device camera or a Bluetooth scanner1.
Therefore, the correct answer is option C, Now Agent Mobile app, as it is the interface that is typically used to initiate a blind inventory audit. References:

What is Hardware Asset Management?

According to the ServiceNow Hardware Asset Management documentation, the core sets of data required for effective IT asset management are:
* Manufacturers: The companies that produce the hardware assets, such as Dell, HP, Cisco, etc.
* Locations: The physical places where the hardware assets are stored or used, such as offices, data centers, warehouses, etc.
* Users: The people who own, use, or manage the hardware assets, such as employees, customers, vendors, etc.
* Models: The specific types or categories of hardware assets, such as laptops, servers, routers, etc.

* The ServiceNow Agent mobile app allows the user to scan and create assets in ServiceNow in various scenarios123.
* One scenario is to create a single asset via barcode scan. The user can scan the barcode or QR code of an asset and fill in the required fields to create an asset record in ServiceNow1.
* Another scenario is to receive one or multiple assets from a purchase order. The user can scan the barcode or QR code of a purchase order and view the list of assets to be received. The user can then scan
* the assets and confirm the receipt in ServiceNow1.
* The other scenarios, such as creating multiple assets listed on a contract PDF scan or creating a single asset via Name search, are not supported by the ServiceNow Agent mobile app123. References:

According to the Hardware Asset Management documentation, a transfer order is a record that tracks the movement of assets from one stockroom to another.
A transfer order line is a record that specifies the quantity and type of assets to be transferred, as well as the source and destination stockrooms1.
When using the HAM application, what happens when you create a new transfer order line on a transfer order is that a transfer order line task is automatically created to move the transfer order line from one stage to another1.
A transfer order line task is a record that tracks the progress of the transfer order line through the following stages1:
Requested: The transfer order line is created and waiting for approval.
Approved: The transfer order line is approved and ready for fulfilment.
Fulfilled: The transfer order line is fulfilled and the assets are shipped from the source stockroom.
Received: The transfer order line is received and the assets are checked in at the destination stockroom.
Closed: The transfer order line is closed and the transfer is complete.
Therefore, the correct answer is option C, a transfer order line task is automatically created to move the transfer order line from one stage to another, as it describes what happens when you create a new transfer order line on a transfer order. References:
