SPLK-1001 Using Fields and Lookups Practice Question
A team uses a lookup to map IP addresses to geographic locations. The lookup is large and updated weekly. Which lookup type is best suited?
⚠ Common exam trap
It's easy for candidates to choose KV store lookup (D) because they assume 'large and updated weekly' implies a database, but KV store is for frequent, incremental updates, not bulk weekly replacements, and CSV lookups are more efficient for static datasets.

Correct answer & explanation
✓
File-based CSV lookup
A file-based CSV lookup is best suited for this use case because it is static, large, and updated on a schedule. CSV lookups are loaded into memory and can handle large datasets efficiently, and they are easily replaced or updated weekly by overwriting the file. This approach avoids the overhead of a KV store or external service for a dataset that does not require real-time updates or complex queries.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
File-based CSV lookup
Why this is correct
CSV lookups are simple, efficient for static data, and easy to update by replacing the file.
- ✗
External lookup
Why it's wrong here
External lookups call external programs; overkill for a simple IP map.
- ✗
Scripted lookup
Why it's wrong here
Scripted lookups require development and are slower; not optimal for a static mapping.
- ✗
KV store lookup
Why it's wrong here
KV store is better for data that changes frequently and needs real-time updates.
