The answer is to configure a JDBC data source and scheduled import set, as this combination allows ServiceNow to connect to an external database via a MID Server and run recurring SQL queries to pull data. This works because the MID Server acts as a secure bridge between ServiceNow and the external database, executing the scheduled SQL query and then using a transform map to map the retrieved data into the correct ServiceNow tables. On the ServiceNow Certified Application Developer CAD exam, this question tests your understanding of integration patterns for recurring data imports, often appearing alongside traps like confusing database views or web services with JDBC. A common pitfall is assuming a direct database connection without a MID Server, but ServiceNow requires the MID Server for external database access in production. Remember the memory tip: "JDBC needs a MID to bridge the gap, then schedule and transform to map."
SNOW-CAD Platform Features and Integration Practice Question
This SNOW-CAD practice question tests your understanding of platform features and integration. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO approaches are valid for importing data from an external database into ServiceNow on a recurring basis? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set up a MID Server to run a scheduled transform map from an external SQL query.
Option A is correct because a MID Server can execute a scheduled SQL query against an external database and then run a transform map to map the retrieved data into ServiceNow tables. This approach is a standard pattern for recurring data imports using the MID Server's JDBC capabilities combined with scheduled import sets.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Set up a MID Server to run a scheduled transform map from an external SQL query.
Why this is correct
MID Server can execute SQL queries and transform data into ServiceNow.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use a REST API with a periodic flow that calls an external endpoint.
Why it's wrong here
This requires the external system to expose a REST API; not universally available.
✗
Write a business rule that triggers on an external event via web service.
Why it's wrong here
Business rules execute on ServiceNow events, not external triggers.
✗
Use an email inbound action to parse CSV attachments from the external system.
Why it's wrong here
Email is not reliable for recurring scheduled imports.
✓
Configure a JDBC data source and scheduled import set.
Why this is correct
JDBC data source integrates with external databases via MID Server.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'importing from an external database' with any external data integration, but the question specifically requires direct database import, which mandates JDBC and a MID Server, not REST APIs or email-based methods.
Detailed technical explanation
How to think about this question
A MID Server acts as a proxy between ServiceNow and an external database, using JDBC drivers to execute SQL queries. The scheduled import set then runs a transform map that can apply field mappings, data transformations, and error handling. In real-world scenarios, this pattern is used for nightly batch imports from legacy systems where direct API access is unavailable, and the MID Server must be installed on a machine with network access to the external database.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
