SNOW-CAD Timed Practice Test 2 — 10 Questions

Question 1

A developer is creating a business rule to automatically assign tasks to a specific group based on the category. The rule is set to run before insert and update on the Task table. The script uses current.assignment_group = 'IT Support'. However, the assignment group is not being set on update even though it works on insert. Which three potential causes should the developer investigate? (Choose three.)

10 minute time limit — choose an answer to begin.

Accepted Answer

The business rule's condition field requires the category to be set. Option A: If the business rule's condition depends on the category field, and the category isn't changed on update, the rule may not run, preventing assignment group update. Option C: If the script only runs on insert but not update, it won't execute on updates. Option E: Another business rule acting after this one could reset the assignment group. Option B: The assignment group being read-only on the form does not stop business rules from setting its value; this is not a cause. Option D: Running only in the global scope does not affect whether the rule runs on update; scope is not a cause.

Answer

The assignment group field is read-only on the form but can be set via business rule

Answer

The business rule is set to run only in the global scope

Question 2

A developer needs to create a new table to store custom survey responses. The table should have a field to store the survey name and a field to store the response text. The developer wants to ensure that the table is available in the 'Surveys' application module. Which property must be set on the table?

Accepted Answer

Application module. The Application module property determines which application module a table belongs to, making it visible and accessible within that module's scope. Setting this to 'Surveys' ensures the table appears in the Surveys application module, as required by the developer.

Answer

Application scope

Answer

Table name

Answer

Table label

Question 3

A ServiceNow instance is configured with a custom table 'u_asset_history' that stores historical records for asset changes. This table has a reference field 'u_asset' pointing to the 'alm_asset' table, and a date field 'u_change_date'. The application uses a business rule that runs on 'alm_asset' after update, querying the 'u_asset_history' table to find the most recent change for that asset. The business rule is declared as 'async' to improve performance. However, recently the async business rule has been failing frequently with an 'async queue limit reached' error. The instance has default configuration for transaction quotas. The team suspects that the async queue is getting overloaded because many asset updates are happening simultaneously. Which action should the administrator take to resolve this issue while minimizing impact on other processes?

Accepted Answer

Increase the system property 'glide.scope.async.quota' to allow more async transactions.. The error 'async queue limit reached' indicates that the instance's asynchronous transaction queue is full, which is a quota issue. Increasing the system property 'glide.scope.async.quota' raises the maximum number of concurrent asynchronous transactions allowed, directly addressing the overload without changing the business logic or impacting other processes. This is the correct approach because the business rule is already optimized to run asynchronously for performance, and the root cause is a capacity limit, not a query or design flaw.

Answer

Add an index on the 'u_asset' and 'u_change_date' fields in the 'u_asset_history' table to optimize the query.

Answer

Rewrite the business rule to run synchronously with a background script to avoid async queue limits.

Answer

Disable the business rule and implement a scheduled job to perform the same logic during off-peak hours.

Question 4

A developer is testing a REST API call to retrieve active users with the ITIL role created since last month. The response returns an error. What is the most likely cause?

Accepted Answer

The query parameter sysparm_query uses a script which is not allowed in REST API calls.. The error occurs because the sysparm_query parameter in a REST API call to the /api/now/table/sys_user endpoint does not support scripts; it only accepts encoded query strings using operators like '=', '^', 'STARTSWITH', etc. Using a script in sysparm_query violates the REST API specification, which expects a simple query string, not executable code, leading to a bad request error.

Answer

The Accept header should be application/xml.

Answer

The endpoint should be /api/now/table/sys_user_list.

Answer

The query should use sysparm_fields instead of sysparm_query.

Question 5

A flow designer wants to send an email notification with a custom logo. They need to ensure the email template references the correct image. What is the best practice?

Accepted Answer

Attach the image to the sys_attachment table and use the sys_id in the template.. Attaching the image to a sys_attachment and using the sys_id reference ensures it persists across upgrades and is the recommended approach.

Answer

Reference the image from an external CDN using a URL.

Answer

Upload the image directly into the email template using base64 encoding.

Answer

Store the image in the 'images' table and use the image name.

Question 6

A ServiceNow administrator is configuring Single Sign-On (SSO) using SAML 2.0 with a corporate identity provider. Users report that after authenticating, they are redirected back to ServiceNow but see an error: 'Unable to process SAML response. Invalid user.' The administrator checks the SSO log and sees the message: 'No user found with username: [user@company.com]'. The username format in the SAML assertion is userPrincipalName (e.g., user@company.com). ServiceNow user records use the 'User ID' field (e.g., 'user'). What configuration change should the administrator make to resolve this issue?

Accepted Answer

Set the 'User Field' property to 'User ID' in the SAML2 configuration to match users based on their User ID. The SAML assertion contains the userPrincipalName (user@company.com), but ServiceNow's default user matching field is the 'User ID' field, which stores only the username (e.g., 'user'). By setting the 'User Field' property to 'User ID' in the SAML2 configuration, ServiceNow will extract the username portion from the NameID (or a custom attribute) and match it against the 'User ID' field, resolving the mismatch. This avoids the need to change user records or the NameID format.

Answer

Change the 'NameID format' from 'Unspecified' to 'EmailAddress' in the SAML2 configuration

Answer

Create an LDAP integration to automatically create ServiceNow users from the identity provider

Answer

Update all ServiceNow user records to have the 'User ID' field populated as full email addresses

Question 7

A developer is debugging an issue where a Script Action in a Flow Designer flow is not triggering. The flow is configured to run when a record is created or updated in the incident table. The Script Action is supposed to set a field based on a condition, but it never executes. What should the developer check first?

Accepted Answer

Check the flow's trigger conditions to ensure they match the record update.. The most common reason a Script Action fails to trigger is that the flow's trigger conditions do not match the record update event. Flow Designer evaluates trigger conditions before any actions execute; if the conditions are misconfigured (e.g., expecting a specific field change that isn't occurring), the entire flow, including the Script Action, will not run. The developer should first verify that the trigger conditions align with the actual record creation or update scenario.

Answer

Check if the flow is published.

Answer

Check if the script include used in the Script Action is accessible.

Answer

Check if the Script Action script has syntax errors.

Question 8

A developer needs to count the number of records in the 'task' table that have been updated since the last import. Which GlideAggregate method is correct?

Accepted Answer

gr.addAggregate('COUNT', 'sys_id'). `addAggregate('COUNT', 'sys_id')` counts all records in the table, as `sys_id` is always present and unique. Option B is wrong because using `'number'` as the field would only count records where the `number` field is not null, potentially undercounting if any records have a null number. Option C is wrong because `addAggregate('COUNT')` omits the required field name, causing an error. Option D is wrong because `'count'` (lowercase) is not a valid aggregate function; the function name must be uppercase, e.g., `'COUNT'`.

Answer

gr.addAggregate('COUNT', 'number')

Answer

gr.addAggregate('COUNT')

Answer

gr.addAggregate('count')

Question 9

What is the most likely cause of this error?

Accepted Answer

The access token has expired or is invalid. A 401 Unauthorized error with Bearer authentication typically means the access token is invalid or expired. Therefore, option B is correct. Option A (timeout) would produce a different error (e.g., 504 Gateway Timeout). Option C (incorrect endpoint URL) would likely result in a 404 Not Found. Option D (missing Content-Type header) might cause a 400 Bad Request, not a 401.

Answer

The request timed out

Answer

The endpoint URL is incorrect

Answer

The Content-Type header is missing

Question 10

A ServiceNow instance is being integrated with an external HR system using a SOAP message. The SOAP call is failing intermittently. The developer notices that the XML payload contains special characters like '&' and '<'. What is the best practice to handle these characters in SOAP messages?

Accepted Answer

Escape the characters using XML entities (e.g., & for &).. SOAP messages are XML-based, and special characters like '&' and '<' must be escaped using XML entities (e.g., & for &, < for <) to maintain valid XML syntax. This ensures the XML parser correctly interprets the payload without breaking the message structure, which is the standard practice per the XML specification and SOAP protocol.

Answer

Wrap the payload in a CDATA section.

Answer

Encode the entire payload in Base64.

Answer

Use URL encoding for the payload.
