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.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
In the same database as the application logs
Why it's wrong here
This creates a significant security risk for the raw data.
- ✓
In a physically or logically segregated environment
Why this is correct
Segregation limits exposure and restricts access to the sensitive mapping database.
- ✗
On the end-user's local workstation
Why it's wrong here
Storing vaults on endpoints is a major security vulnerability.
- ✗
Integrated directly into the web server memory
Why it's wrong here
Memory-resident vaults are prone to scraping attacks.
