Start with Data
This tells you when a sensor value was actually measured rather than when somebody looked at it.
What is a timestamp?
The FDD specification identifies five standard interfaces/protocols for ingesting building data. Name three.
What are BACnet/IP, Modbus TCP/IP, OPC UA, MQTT and RESTful APIs?
Lightweight publish/subscribe protocol heavily associated with IoT telemetry.
What is MQTT?
AI technique that learns patterns from data rather than relying exclusively on predefined rules.
What is machine learning?
Structured cabling.
27
Garbage in, garbage out: this term describes whether data is accurate, complete, consistent and usable.
What is data quality?
Detecting a fault isn't enough. For every detected issue, the system must provide the affected equipment, fault description, recommended action and this diagnostic insight.
What is the probable root cause?
JSON, XML and SQL are protocols. True or false?
False — they are data formats and query languages
AI technique commonly used to identify unusual behavior without explicitly programming every possible fault.
What is anomaly detection?
EV charging
Temperature is sampled every second but transmitted every five minutes. These are two different data characteristics.
What are sampling rate and reporting/update frequency?
What does RUL mean in predictive maintenance?
Remaining Useful Life.
A specification states “BACnet/IP over RS-485.” What's wrong?
BACnet/IP uses IP networking; BACnet MS/TP is the common RS-485 variant.
This AI architecture retrieves enterprise information before generating an answer.
What is RAG?
Cybersecurity for Enterprise Network

23.7 becomes significantly more useful when you know it represents ZoneTemperature for Room-201. This added information is called this.
What is context / metadata?
What two open semantic models are explicitly mentioned?
Project Haystack and Brick Schema.
The API exposes functionality/data; this provides tools/libraries/documentation that simplify developing against it.
What is an SDK
Why might an AI workload be placed at the edge rather than in the cloud?
Latency, bandwidth, resilience, privacy/security or operational requirements.
UPS
26
What type of database is particularly suited to storing large volumes of timestamped sensor readings?
What is a time-series database?
What's the difference between predictive and prescriptive functionality in our specification?
Predictive identifies likely future failures/degradation; prescriptive recommends prioritized actions.
Unlike Wi-Fi, this technology trades high throughput for very long range, low power consumption and years of potential battery life, making it suitable for distributed environmental and utility sensors.
What is Lorawan
Providing insight into why the model produced its output, including contributing variables/confidence where applicable.
