SNOW-CAD Integrating and managing application data Practice Question
Which TWO are best practices for integrating with external systems via REST API in ServiceNow?
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 a credential store or use OAuth for authentication.
Options B and E are best practices. Storing credentials in a credential store or using OAuth (option B) enhances security over basic authentication (option C is incorrect). Using HTTPS (option E) encrypts data in transit, protecting it from interception. Option A is wrong because GlideRecordSecure API is actually recommended for secure REST endpoint operations. Option D is incorrect because the sysparm_query parameter filters records but does not limit the number of records returned; use sysparm_limit for that purpose.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Avoid using the GlideRecordSecure API for REST endpoints.
Why it's wrong here
GlideRecordSecure is recommended to enforce security, so avoiding it is not a best practice.
- ✓
Store credentials in a credential store or use OAuth for authentication.
Why this is correct
Using a credential store or OAuth avoids hardcoding credentials and improves security.
- ✗
Use basic authentication with username and password for all REST API requests.
Why it's wrong here
Basic authentication is less secure; OAuth or credential stores are preferred.
- ✗
Use the sysparm_query parameter to limit the number of records returned.
Why it's wrong here
While limiting results is good, it is not specifically about authentication or security; it is a performance optimization.
- ✓
Always use HTTPS to encrypt data in transit.
Why this is correct
HTTPS ensures data is encrypted during transmission, a fundamental security best practice.
