SNOW-CAD Integrating and managing application data Practice Question
A developer is creating a REST API integration that retrieves data from an external system and updates ServiceNow records. Which THREE considerations are critical for handling authentication securely? (Choose three.)
⚠ Common exam trap
Many exam-takers confuse operational monitoring (Option A) with proactive authentication security controls, and reversing the authentication direction in Option B, leading candidates to select measures that are either reactive or misdirected.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Store credentials in the ServiceNow Credential Store instead of scripts
Storing credentials directly in scripts exposes them to unauthorized access and makes rotation difficult. The ServiceNow Credential Store securely encrypts and manages credentials, allowing scripts to reference them by alias without hardcoding sensitive data, which is a fundamental security best practice for REST API integrations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable credential monitoring in the Security Operations Center
Why it's wrong here
Monitoring is operational, not a design consideration for the integration itself.
- ✗
Configure the external system to authenticate ServiceNow requests
Why it's wrong here
That is inbound authentication, not relevant to outbound calls from ServiceNow.
- ✓
Store credentials in the ServiceNow Credential Store instead of scripts
Why this is correct
The Credential Store encrypts and manages secrets, reducing exposure.
- ✓
Use OAuth2.0 with refresh tokens for long-lived access
Why this is correct
Refresh tokens allow secure renewal without storing long-lived secrets.
- ✓
Ensure the REST endpoint uses HTTPS
Why this is correct
HTTPS encrypts data in transit, preventing interception.
