Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Critical
Why this is correct
Handling customer PII plus daily operational dependency means a vendor outage or breach causes regulatory, financial and continuity impact simultaneously. That combination of data sensitivity and operational criticality places the vendor in the critical tier, matching the stem's tiering criteria.
- ✗
Medium
Why it's wrong here
Medium understates a vendor holding customer PII and supporting daily operations, which demands the highest tier and scrutiny. Tiering by data sensitivity and operational criticality places such a vendor at high. Medium fits vendors with limited data access whose outage causes only minor, recoverable disruption.
- ✗
High
Why it's wrong here
High tier is often used, but 'critical' is more specific in CRISC.
- ✗
Low
Why it's wrong here
Low tiering applies to vendors with minimal data access and negligible operational dependency, requiring only periodic review. A vendor holding customer PII and underpinning daily operations fails both tests, so it cannot sit at the lowest tier.
