Which solution is most appropriate?
A) Data aggregation tool
B) VPN connection
C) Printer sharing
D) Increasing monitor brightness
Solution
Correct answers: Data aggregation tool – Explanation:
Data aggregation tools collect and unify data from multiple sources for comprehensive analysis. VPN, printers, or display changes do not support data integration.

Which technology should be implemented?
A) Machine learning
B) Static dashboards
C) Manual spreadsheet entry
D) Paper logbooks
Solution

Which approach is most suitable?
A) Data anonymization
B) Adding more storage
C) Changing font color
D) Reducing CPU speed

Which feature should be implemented?
A) Live data dashboards
B) Manual weekly reports
C) Archival storage
D) Screen savers

What is the best solution?
A) Implement data validation checks
B) Increase network bandwidth
C) Allow user uploads without review

Which process accomplishes this?
A) Data replication
B) Replace all client devices
C) Upgrade lighting
D) Increasing monitor brightness
Solution

Which feature is essential?
A) Audit trail
B) Adding more monitors
C) Changing wallpaper
D) Increasing storage quota
Solution
Correct answers: Data aggregation tool – Explanation:

Which data visualization is best?
A) Interactive map
B) Pie chart
C) Line graph

Solution
Correct answers: Interactive map – Explanation:
