Actual exam question for CWNP's CWISA-102 exam

Question #: 40
Topic #: 3

[All CWISA-102 Questions]

What is a common characteristic of Industrial IoT (IIoT) devices that is not a characteristic of all IoT devices?

ARuggedized devices constructed for operating in harsh environments

BUse of standardized protocols

CTransmission of small amounts of data throughout the day

DUse of proprietary protocols

Show Suggested Answer

Suggested Answer: A

IIoT Environments:Industrial IoT (IIoT) often involves deployment in harsh environments (factories, plants, outdoor sites) with:

Extreme temperatures

Dust & Vibrations

Exposure to chemicals or moisture

Ruggedization:IIoT devices are designed to withstand these conditions, ensuring reliability and longevity.

Option B is a bit too broad. Standardized protocols are used in both consumer and industrial IoT, so that's not a unique IIoT trait.

Ruggedized devices are definitely a key characteristic of IIoT, but not all IoT devices need that level of durability.

I recall that proprietary protocols are often used in IIoT, but I don't think that's unique to them. A sounds more specific to IIoT.

I practiced a question about data transmission in IIoT, and I think they usually send small amounts of data, but that seems too general for this question.

I'm not entirely sure, but I feel like standardized protocols are more common across all IoT devices, not just IIoT.

I think I remember that IIoT devices are often ruggedized for tough environments, so A might be the right choice.

I'm pretty confident the answer is D. IIoT devices often use proprietary protocols, unlike general consumer IoT which tends to rely more on standardized protocols. The other choices don't seem to differentiate IIoT from IoT.

This is a tricky one. I was thinking the use of proprietary protocols might be the key, but then I realized that's not necessarily unique to IIoT. I'll have to re-read the question and options closely.

Okay, I've got it. IIoT devices are built to withstand harsher environments, so option A has to be the answer. The other choices seem to apply to both IIoT and general IoT.

Hmm, I'm a bit unsure about this one. I know IIoT devices are used in industrial settings, but I'm not totally clear on how they differ from consumer IoT devices. I'll have to think this through carefully.

I think the key here is to focus on the differences between IIoT and general IoT devices. Ruggedized construction and proprietary protocols seem like the most distinguishing factors.
