CWNP Certified Wireless IoT Solutions Administrator(2025 Edition) 認定 CWISA-103 試験問題 (Q79-Q84):

質問 # 79
Which of the following is a characteristic of 802.15.4 networks such as Zigbee?

A. Extremely long range (tens of kilometers)
B. Operation only on 5 GHz
C. Very high throughput (hundreds of Mbps)
D. Mesh networking support

正解：D

解説：
Zigbee supports mesh networking for extended coverage and reliability. It offers low throughput, typically operates at 2.4 GHz, and is not long-range.

質問 # 80
Which layer of the OSI model includes encryption protocols such as TLS used in IoT cloud communication?

A. Layer 7 (Application)
B. Layer 4 (Transport)
C. Layer 2 (Data Link)
D. Layer 3 (Network)

正解：B

解説：
TLS typically runs over TCP at the Transport Layer (Layer 4), securing communication sessions between devices and cloud services.

質問 # 81
How does OFDMA differ from OFDM?

A. OFDMA uses multiple radios to achieve higher throughput
B. OFDMA allows multiple devices to transmit simultaneously on the same frequency
C. Subcarriers of OFDMA can contain data destined for a different receiver
D. OFDMA offers greater range by using multiple channels at once

正解：B

解説：
* OFDM vs. OFDMA:
* OFDM (Orthogonal Frequency-Division Multiplexing): Divides a channel into multiple subcarriers for data transmission.
* OFDMA (Orthogonal Frequency-Division Multiple Access): Extends OFDM by allowing multiple users to share subcarriers simultaneously, improving efficiency and spectral utilization.

質問 # 82
How does OFDMA differ from OFDM?

A. OFDMA uses multiple radios to achieve higher throughput
B. OFDMA allows multiple devices to transmit simultaneously on the same frequency
C. Subcarriers of OFDMA can contain data destined for a different receiver
D. OFDMA offers greater range by using multiple channels at once

正解：B

質問 # 83
Which one of the following is NOT a typical Smart City application?

A. Demand-based road tolling
B. Pollution monitoring
C. City-wide municipal Wi-Fi
D. Self-driving ride sharing

正解：D

解説：
Smart City Focus: Smart city initiatives mainly address infrastructure, environmental monitoring, and optimization of public services.
Ride-sharing Context: While self-driving technology could contribute to future smart city transportation, it's primarily a private-sector innovation, not a core municipal service like the other options.
