SNOW-CAD Core Application Development Practice Question
Which TWO of the following are valid ways to reference a sys_id of a record in a business rule? (Choose two.)
⚠ Common exam trap
ServiceNow often tests the distinction between field values (like `current.number`) and the unique record identifier (sys_id), leading candidates to mistakenly choose `current.number` as a valid sys_id reference.

Correct answer & explanation
✓
current.getUniqueValue()
Options B, C, and E are all valid ways to reference the sys_id of a record in a business rule. Option B uses the `getUniqueValue()` method, which returns the sys_id even for new unsaved records. Option C uses `current.get('sys_id')` to retrieve the sys_id field value. Option E directly accesses the `sys_id` field via dot notation. All three methods correctly return the unique identifier of the current record.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
current.number
Why it's wrong here
Incorrect. `current.number` retrieves the value of the 'number' field, not the sys_id. It is a field value but not the unique record identifier.
- ✓
current.getUniqueValue()
Why this is correct
Correct. `getUniqueValue()` is a GlideRecord method that returns the sys_id of the current record.
- ✓
current.get('sys_id')
Why this is correct
Correct. `get('sys_id')` is a GlideRecord method that retrieves the value of the 'sys_id' field.
- ✗
current.getRow()
Why it's wrong here
Incorrect. There is no `getRow()` method in GlideRecord. This is a distractor.
- ✓
current.sys_id
Why this is correct
Correct. `current.sys_id` directly accesses the sys_id field of the GlideRecord object.
