SPLK-1002 Advanced Visualization and Lookups Practice Question
A security analyst needs to correlate IP addresses from firewall logs with a lookup table containing known malicious IPs. The lookup table is updated hourly and contains 10,000 entries. Which lookup type should be used to ensure the fastest search performance?
⚠ Common exam trap
Many candidates choose KV Store lookup (Option C) because it supports dynamic updates, but they overlook that for small, frequently reloaded static datasets, a file-based CSV lookup is faster due to its in-memory caching and lack of network dependency.

Correct answer & explanation
✓
File-based CSV lookup
A file-based CSV lookup is the correct choice because it is stored entirely in memory on the search head, providing the fastest access for small to medium-sized static datasets (like 10,000 entries). Since the lookup is updated hourly, a CSV file can be reloaded efficiently without the overhead of network calls or database queries, making it ideal for high-speed correlation in security searches.
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 loaded into memory and fast for moderate sizes.
- ✗
External lookup
Why it's wrong here
External lookups add network overhead.
- ✗
KV Store lookup
Why it's wrong here
KV Store is slower for simple key-value matching.
- ✗
Geospatial lookup
Why it's wrong here
Geospatial is for coordinates, not IP matching.
