Question 180

A developer proposes this approach: Use an appropriate onSubmit Client Script for immediate feedback and enforce the rule on the server too. Which business requirement is the strongest reason to choose it?

  1. When a request type is set to Internal, a justification field should be hidden on that desktop form.
  2. A desktop field script appears not to run after a priority change.
  3. A form needs to retrieve a calculated account status from server-only data without exposing direct database access in the browser.
  4. A custom form should block accidental submission when a required business acknowledgement is missing.

Explanation

Correct Answer

D:

This business need directly motivates Use an appropriate onSubmit Client Script for immediate feedback and enforce the rule on the server too; Client-side submission checks improve usability but cannot be the sole source of data validation.

Incorrect Answers

A:

The described situation is better addressed by Use a supported g_form API in client logic or a UI Policy to control field visibility. Client UI controls modify presentation and should not be treated as record security.

B:

The described situation is better addressed by Check script type, target table and field, then debug in the browser with a reproducible test. Client execution failures require inspecting browser-side conditions rather than server logs alone.

C:

The described situation is better addressed by Use GlideAjax with an appropriately secured client-callable Script Include when applicable. A supported asynchronous client-server call keeps privileged data access on the server.

Question 181

When a request type is set to Internal, a justification field should be hidden on that desktop form. Which application design or configuration action best addresses this requirement on the ServiceNow platform?

  1. Check script type, target table and field, then debug in the browser with a reproducible test
  2. Use a supported g_form API in client logic or a UI Policy to control field visibility
  3. Use GlideAjax with an appropriately secured client-callable Script Include when applicable
  4. Use an appropriate onLoad Client Script to set a client-side message

Explanation

Correct Answer

B:

Correct for g_form field visibility: Client UI controls modify presentation and should not be treated as record security.

Incorrect Answers

A:

That action instead addresses Debug client execution. Client execution failures require inspecting browser-side conditions rather than server logs alone. It does not directly fulfill the stated g_form field visibility requirement.

C:

That action instead addresses Client to server lookup. A supported asynchronous client-server call keeps privileged data access on the server. It does not directly fulfill the stated g_form field visibility requirement.

D:

That action instead addresses On-load client guidance. An onLoad script executes when the form loads in supported clients and can guide the user. It does not directly fulfill the stated g_form field visibility requirement.

Question 182

A developer applies this approach: Use a supported g_form API in client logic or a UI Policy to control field visibility. What platform behavior or outcome should be expected for the stated design?

  1. Client execution failures require inspecting browser-side conditions rather than server logs alone.
  2. A supported asynchronous client-server call keeps privileged data access on the server.
  3. Client UI controls modify presentation and should not be treated as record security.
  4. An onLoad script executes when the form loads in supported clients and can guide the user.

Explanation

Correct Answer

C:

The expected result for g_form field visibility is: Client UI controls modify presentation and should not be treated as record security.

Incorrect Answers

A:

This describes Debug client execution and its associated action, Check script type, target table and field, then debug in the browser with a reproducible test, rather than the consequence of the stated approach.

B:

This describes Client to server lookup and its associated action, Use GlideAjax with an appropriately secured client-callable Script Include when applicable, rather than the consequence of the stated approach.

D:

This describes On-load client guidance and its associated action, Use an appropriate onLoad Client Script to set a client-side message, rather than the consequence of the stated approach.

Question 183

When a request type is set to Internal, a justification field should be hidden on that desktop form. A teammate suggests a different change: Check script type, target table and field, then debug in the browser with a reproducible test. That change does not resolve the actual requirement. Which correction is most appropriate?

  1. Check script type, target table and field, then debug in the browser with a reproducible test
  2. Use GlideAjax with an appropriately secured client-callable Script Include when applicable
  3. Use an appropriate onLoad Client Script to set a client-side message
  4. Use a supported g_form API in client logic or a UI Policy to control field visibility

Explanation

Correct Answer

D:

Use the indicated corrective approach. Client UI controls modify presentation and should not be treated as record security. This meets the specific requirement for g_form field visibility.

Incorrect Answers

A:

Not the appropriate correction: Check script type, target table and field, then debug in the browser with a reproducible test is relevant to Debug client execution. Client execution failures require inspecting browser-side conditions rather than server logs alone.

B:

Not the appropriate correction: Use GlideAjax with an appropriately secured client-callable Script Include when applicable is relevant to Client to server lookup. A supported asynchronous client-server call keeps privileged data access on the server.

C:

Not the appropriate correction: Use an appropriate onLoad Client Script to set a client-side message is relevant to On-load client guidance. An onLoad script executes when the form loads in supported clients and can guide the user.

  1. When a request type is set to Internal, a justification field should be hidden on that desktop form.
  2. A desktop field script appears not to run after a priority change.
  3. A form needs to retrieve a calculated account status from server-only data without exposing direct database access in the browser.
  4. A browser form should show an informational help message as soon as the request form opens.

Explanation

Correct Answer

A:

This business need directly motivates Use a supported g_form API in client logic or a UI Policy to control field visibility; Client UI controls modify presentation and should not be treated as record security.

Incorrect Answers

B:

The described situation is better addressed by Check script type, target table and field, then debug in the browser with a reproducible test. Client execution failures require inspecting browser-side conditions rather than server logs alone.

C:

D:

The described situation is better addressed by Use an appropriate onLoad Client Script to set a client-side message. An onLoad script executes when the form loads in supported clients and can guide the user.

Question 185

A desktop field script appears not to run after a priority change. Which application design or configuration action best addresses this requirement on the ServiceNow platform?

  1. Use GlideAjax with an appropriately secured client-callable Script Include when applicable
  2. Use an appropriate onLoad Client Script to set a client-side message
  3. Check script type, target table and field, then debug in the browser with a reproducible test
  4. Use an onChange Client Script with a guard for loading and the relevant field

Explanation

Correct Answer

C:

Correct for Debug client execution: Client execution failures require inspecting browser-side conditions rather than server logs alone.

Incorrect Answers

A:

That action instead addresses Client to server lookup. A supported asynchronous client-server call keeps privileged data access on the server. It does not directly fulfill the stated Debug client execution requirement.

B:

That action instead addresses On-load client guidance. An onLoad script executes when the form loads in supported clients and can guide the user. It does not directly fulfill the stated Debug client execution requirement.

D:

That action instead addresses On-change dependent prompt. onChange handles an edited field while load-time guards prevent unintended initialization effects. It does not directly fulfill the stated Debug client execution requirement.

Question 186
