QUESTION AND CORRECT ANSWER WITH
EXPLANATION WEST COAST UNIVERSITY
1. A hospital’s AI-driven clinical decision support system
recommends a medication that conflicts with a patient’s documented
allergy. Investigation reveals the allergy was recorded using a non-
standard term. Which issue is MOST responsible?
A. Network latency
B. Lack of semantic interoperability
C. Data encryption failure
D. System downtime
Correct Answer: B
Rationale: Non-standard terminology prevents systems from correctly
interpreting clinical data, leading to unsafe recommendations.
2. A Health IT specialist is designing a high-availability EHR system
across multiple regions. Which architecture BEST ensures
continuous operation during regional outages?
A. Single data center deployment
B. Active-passive failover within one site
C. Multi-region active-active architecture
D. Local backup storage only
Correct Answer: C
Rationale: Active-active multi-region systems allow simultaneous
operation and automatic failover, ensuring high availability.
3. A hospital integrates genomic data into its Electronic Health
Record (EHR). Which challenge is MOST critical for clinical
usability?
A. Data compression
B. Data interpretation and clinical relevance
,C. Data storage cost only
D. Network bandwidth
Correct Answer: B
Rationale: Genomic data must be translated into actionable clinical
insights to be useful.
4. A clinician ignores multiple low-priority alerts and misses a critical
one. Which system redesign is MOST effective?
A. Increase alert frequency
B. Implement intelligent alert filtering
C. Remove all alerts
D. Delay alerts
Correct Answer: B
Rationale: Intelligent filtering prioritizes critical alerts and reduces alert
fatigue.
5. A ransomware attack encrypts both primary and backup systems.
Which failure contributed MOST to this outcome?
A. Lack of encryption
B. Absence of offline/immutable backups
C. Weak passwords only
D. Data normalization issues
Correct Answer: B
Rationale: Offline or immutable backups prevent ransomware from
encrypting backup data.
6. A Health IT system uses FHIR APIs for real-time data exchange.
Which risk increases with this approach?
A. Reduced interoperability
B. API security vulnerabilities
C. Data redundancy
D. Data compression issues
, Correct Answer: B
Rationale: APIs introduce attack surfaces that must be secured through
authentication and monitoring.
7. A hospital merges two large patient databases. Which technique
BEST minimizes duplicate patient records?
A. Deterministic matching only
B. Probabilistic matching algorithms
C. Manual review only
D. Data compression
Correct Answer: B
Rationale: Probabilistic matching improves accuracy by evaluating
multiple identifiers.
8. A Health IT specialist evaluates system performance degradation
during peak hours. Which metric is MOST critical?
A. Data size
B. Throughput and response time
C. Number of users only
D. Data redundancy
Correct Answer: B
Rationale: Throughput and response time directly reflect system
performance under load.
9. A hospital integrates multiple systems using HL7 v2 messages.
Which limitation is MOST significant?
A. Lack of flexibility and modern API support
B. Excessive encryption
C. High scalability
D. Real-time capability
