CMO Data Collection & Monitoring 4

Question 1

When designing a data collection form for field use, which best practice reduces data entry errors for categorical fields?

Accepted Answer

Dropdown menus or radio buttons with predefined options

Answer

Constrained input controls like dropdowns restrict entries to valid choices, eliminating spelling errors and non-standard values at the point of collection.

Question 2

A dashboard shows that one data stream has a 15% packet loss rate. What is the most likely operational impact?

Accepted Answer

Gaps in the monitoring timeline and potentially missed alerts

Answer

Packet loss creates gaps in the data timeline, which can cause missed alert conditions and incomplete records that compromise monitoring integrity.

Question 3

Which data compression strategy is most appropriate when transmitting sensor data over a low-bandwidth mobile connection?

Accepted Answer

Delta encoding that transmits only changes from the last reported value

Answer

Delta encoding reduces payload size significantly for slowly changing sensor data by transmitting only the difference from the previous value rather than full readings.

Question 4

What is a 'dead band' setting in a monitoring configuration?

Accepted Answer

A range around a threshold within which small fluctuations do not trigger repeated alerts

Answer

A dead band defines a tolerance range around a threshold so that minor oscillations near the threshold do not cause rapid repeated alert toggling.

Question 5

In Mobilyze, what is the correct action when a mandatory field in a data collection form is left blank upon submission attempt?

Accepted Answer

Submission is blocked and the operator is prompted to complete the required field

Answer

Mandatory field validation blocks form submission and directs the operator to the empty field, ensuring data completeness at the point of entry.
