SNOW-CSA Practice Test 26 — 15 Questions

Question 1

A form has a field with a default value that is automatically populated when a new record is created. The administrator wants to change this default value. Where should the administrator set the new default?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Dictionary entry for the field. The default value for a field is stored in the dictionary entry for that field. Changing the default value in the dictionary entry ensures that all new records created after the change will use the new default. This is the correct and intended method for setting field defaults in ServiceNow.

Answer

Business Rule

Answer

UI Policy

Answer

Client Script

Question 2

Which TWO attributes are essential for identifying configuration items in the CMDB to ensure uniqueness? (Choose exactly 2.)

Accepted Answer

MAC address. (MAC address) is correct because a MAC address is a globally unique hardware identifier assigned to network interfaces by the manufacturer, making it a reliable and immutable attribute for uniquely identifying configuration items (CIs) such as servers, switches, and workstations in the CMDB. In ServiceNow, the MAC address is often used as a deduplication key to prevent duplicate CIs, especially when discovered via network probes or agents. Its uniqueness is guaranteed at the hardware level, unlike attributes that can be changed or reassigned.

Answer

Asset tag

Answer

Name

Answer

IP address

Question 3

An SLA is defined for incident resolution with a 4-hour breach timer. The SLA should not count time when the incident is in 'Awaiting Customer' status. The administrator has configured a pause condition on the SLA definition. However, when the state changes to 'Awaiting Customer', the SLA timer continues to run. The administrator wants to troubleshoot the issue. What should the administrator check first?

Accepted Answer

Verify the SLA pause condition script or condition.. The pause condition on the SLA definition is the primary mechanism that stops the breach timer when the incident enters a specific state, such as 'Awaiting Customer'. If the timer continues to run despite the state change, the most likely cause is that the pause condition script or condition is incorrectly configured, not evaluating to true, or missing entirely. The administrator should first verify this condition before investigating other potential issues.

Answer

Ensure the business rule that triggers SLA recalculation is active.

Answer

Check the SLA metric timeline.

Answer

Check the SLA schedule for the 'Pause' field.

Question 4

A company wants to display a custom field on the incident form only when the incident state is 'In Progress'. Which configuration should be used?

Accepted Answer

Create a UI Policy with a condition on state and set field visibility. UI Policies allow you to define a condition (e.g., incident.state == 'In Progress') and then set field-level actions such as making a field visible or mandatory. This is the intended declarative mechanism for controlling field visibility based on form state without writing code.

Answer

Modify the Dictionary Override to set a default visibility condition

Answer

Configure an Access Control Rule (ACL) on the field

Answer

Write a Business Rule that updates the field visibility attribute

Question 5

An import set transform map has a field mapping that uses a 'Run script' action. The script sets a reference field by querying the target table. However, the import fails with a 'Null reference' error. What is the most likely issue?

Accepted Answer

The script is not using the correct record identifier. The import fails with a 'Null reference' error because the script in the field mapping uses a query that does not find a matching record in the target table, resulting in a null value for the reference field. Option A is correct: the script is likely not using the correct record identifier (e.g., sys_id or a unique field) to locate the target record, so the query returns no results. Option B is incorrect because read-only fields do not cause null reference errors; they prevent field updates. Option C is incorrect because 'Atomic update' mode is unrelated to reference field errors; it affects how transforms are processed. Option D is incorrect because the coalesce field determines how source rows are matched to target rows, but the error here occurs during field mapping execution, not during coalescing.

Answer

The target field is read-only

Answer

The transform map is set to 'Atomic update'

Answer

The coalesce field is set incorrectly

Question 6

A large enterprise uses ServiceNow for IT service management. They have a catalog item 'New Employee Setup' that is used by HR to request IT resources for new hires. The catalog item includes variables for employee name, start date, department, and manager. The workflow associated with this item creates a catalog task for the desktop team to prepare a laptop, and another catalog task for the network team to create accounts. Recently, the desktop team has been receiving tasks with incomplete information; the employee name variable is sometimes empty even though it is marked as mandatory. The administrator checked the variable definition and confirmed 'Mandatory' is set to 'true'. The variable is a 'Single Line Text' with no default value. The issue happens intermittently. What course of action should the administrator take to resolve this issue?

Accepted Answer

Add a workflow script activity that checks if the variable is empty and rejects the request if so.. The issue is that the mandatory field validation is being bypassed intermittently, likely due to the catalog item being submitted via a web service, REST API, or an integration where client-side mandatory checks are not enforced. Adding a workflow script activity that checks the variable value server-side ensures that even if the client-side validation fails, the request is rejected before proceeding, providing a reliable server-side guard.

Answer

Reorder the workflow activities so that the validation occurs earlier.

Answer

Change the variable type to 'Email' to enforce stronger validation.

Answer

Set the variable to 'Read only' and populate it from a reference field.

Question 7

You are a ServiceNow administrator at a mid-sized company. The CMDB currently has over 100,000 CIs, and end users report that the CI search results are slow, often taking more than 10 seconds. The database has been optimized, but the issue persists. You have noticed that many CIs have empty or outdated fields. What is the best course of action to improve search performance without impacting data integrity?

Accepted Answer

Run the CMDB Data Manager to clean up empty fields and reduce index size.. The CMDB Data Manager can identify and remove empty or outdated fields from CI records, which reduces the size of the database indexes. Smaller indexes improve search query performance without deleting entire CIs, thus preserving data integrity. This directly addresses the root cause—bloated indexes due to unnecessary data—rather than masking the issue with connection pool changes or risking data loss.

Answer

Create a scheduled job to delete CIs that have not been updated in 90 days.

Answer

Disable the full-text search index and rely on basic database indexes.

Answer

Increase the database connection pool size and restart the instance.

Question 8

A user has personalized their form by rearranging fields. The administrator wants to reset the form layout to the default for that user. What should the administrator do?

Accepted Answer

Delete the user's personalization from sys_user_preference. User-specific form layout customizations are stored in the sys_user_preference table. Deleting the relevant preference record for that user resets the form to the default layout without affecting other users or system-wide settings.

Answer

Set the form's 'Reset' attribute to true

Answer

Run a scheduled job to clear all user preferences

Answer

Use the 'Restore Default' button on the form

Question 9

Refer to the exhibit. An import set has a row with short_description='Test', category='network', and number='INC001'. The target table has an existing record with number='INC001' and description='Old Desc'. What will happen when the transform runs?

Accepted Answer

The existing record is updated with description='Test'.. The transform uses the coalesce field 'number' to match the incoming record (number='INC001') with the existing target record (number='INC001'). Since a match is found, the transform performs an update operation. The short_description field from the import set row ('Test') is mapped to the description field on the target table, so the existing record's description is updated to 'Test'.

Answer

The transform fails due to coalesce conflict.

Answer

A new record is created.

Answer

No action because coalesce field is invalid.

Question 10

Which TWO of the following are valid ways to define who receives a notification in ServiceNow? (Choose two.)

Accepted Answer

Users in a role. ServiceNow allows notifications to be sent to all users who have a specific role assigned. When 'Users in a role' is selected as the recipient type, the system evaluates the role membership at runtime and sends the notification to every active user with that role, making it a valid and commonly used recipient definition.

Answer

Email address

Answer

Dynamic recipient

Answer

Group

Question 11

A large import set of 10,000 user records from an HR system is failing intermittently during transformation to the sys_user table. Some rows are inserted successfully, but others show errors in the import log: 'Transform script error: null reference at line 15 of the transform map script.' The administrator reviews the transform map and finds a script that sets the department field by looking up a department table. The script assumes the department code always exists in the department table, but some records have codes that are not present. The administrator needs to ensure all rows are imported reliably, even if some data is missing. What is the best course of action?

Accepted Answer

Fix the transform script to check for the existence of the department code before using it, and set a default value or skip the field if not found. Then use an Import Set Row condition to only process rows that are valid.. It directly addresses the root cause: the transform script fails when a department code is missing from the reference table. By adding a null check before using the lookup result and providing a default or skipping the field, the script becomes resilient to missing data. Using an Import Set Row condition then ensures that only rows with valid department codes are processed, preventing the intermittent null reference errors while still importing all other rows successfully.

Answer

Use a 'Run as GlideRecord' operation in the transform map to ensure each row is processed individually.

Answer

Create a separate import set for each user record to isolate failures.

Answer

Add a condition to skip rows that have null values in the department field.

Question 12

An organization is planning to implement CMDB for a large-scale environment with multiple data sources. They need to ensure that the most trustworthy data source takes precedence when conflicts occur. Which feature should they use?

Accepted Answer

Data Source Priority. Data Source Priority (Option D) is the correct feature because it allows administrators to define a hierarchy of data sources in the CMDB, ensuring that when multiple sources provide conflicting attribute values for the same CI, the source with the highest priority (lowest numeric value) is trusted and its data is used. This directly addresses the requirement to make the most trustworthy data source take precedence in a large-scale, multi-source environment.

Answer

Identification & Reconciliation engine

Answer

Reconciliation

Answer

Set source precedence in the CI class manager for each CI

Question 13

An administrator discovers that a scheduled discovery job is creating duplicate CI records for the same physical server. The server has two IP addresses (one for management, one for production). What is the most likely cause?

Accepted Answer

The identification rule for the CI class does not include a unique hardware identifier like serial number.. ServiceNow's CMDB uses identification rules to determine whether a discovered CI is new or matches an existing record. For a physical server with multiple IP addresses, the identification rule must include a unique hardware identifier such as a serial number (e.g., from SMBIOS) to prevent duplicate CIs. Without that, the system may treat each IP address as a separate CI, even though they belong to the same server.

Answer

The discovery schedule is set to run too frequently.

Answer

The discovery job is configured to scan only the management IP.

Answer

The server has too many IP addresses for discovery to handle.

Question 14

A company frequently imports data from an external HR system into the Employee [hr_employee] table using an import set. The import set runs nightly and maps fields correctly. Recently, the import started failing with the error 'Field 'manager' not found in table 'hr_employee''. The manager field exists in the import set rows but not in the target table. What is the most likely cause?

Accepted Answer

The transform map has a field mapping that references 'manager' as a target field, but the hr_employee table does not have a 'manager' column.. The error 'Field 'manager' not found in table 'hr_employee'' indicates that the transform map is attempting to map a source field to a target column that does not exist in the hr_employee table. Since the import set rows contain the 'manager' field, the mapping in the transform map must be referencing 'manager' as a target field, but the target table lacks that column. This is the most likely cause because the transform map defines the field-to-field mapping between the import set row and the target table, and if the target field name is incorrect or missing from the table, the import will fail.

Answer

The import set row table (sys_import_set_row) does not have a 'manager' column.

Answer

The source CSV file contains a column named 'manager' that is misspelled.

Answer

The manager field in the target table is of a different data type (e.g., string vs reference).

Question 15

Refer to the exhibit. This condition script is used in a notification. For which states will the notification trigger?

Accepted Answer

Both state 2 and state 3. The condition script uses `current.state.changesTo(3)` which returns true only when the state transitions to 3 from a different state. Since the script also includes `current.state == 2`, the notification triggers for state 2 as well. Therefore, both state 2 and state 3 will cause the notification to fire.

Answer

Only state 3

Answer

Only state 2

Answer

Neither state 2 nor state 3
