2. When two IoT devices wish to communicate, semantic conflict in such a scenario in IoT interoperability refers to_____________.
Options:
a. Two devices built by the same manufacturer
b. Two devices having different processing and business logic
c. Two devices sensing the same physical parameter
d. Two devices having different deployment location

Answer: b

Explanation:
Semantic conflict arises when devices interpret data differently due to varying logic or meanings, even if the structure of data is the same.

3. Which of the following issues needs to be addressed while solving user interoperability?
Options:
a. Device characterization and identification
b. Syntactic interoperability
c. Both (a) and (b)
d. None of these

Answer: c

Explanation:
User interoperability requires both understanding device types and ensuring data formats are compatible, hence both options a and b.

4. State whether the following statement is true or false: UMB core interoperability component is responsible for converting physical devices into virtually abstracted ones.
Options:
a. False
b. True

Answer: a

Explanation:
The UMB component doesn’t convert physical devices directly into virtual abstractions; it facilitates communication and data transfer via middleware protocols.

5. What is the full form of UMB in IoT interoperability?
Options:
a. Universal Middleware Bridge
b. Universal Main Bridge
c. Universal Main Bracket
d. None of these

Answer: a

Explanation:
UMB stands for Universal Middleware Bridge, which helps bridge communication between heterogeneous IoT systems.

6. Which of the following is NOT a function available in the Servo library for Arduino?
Options:
a. kill()
b. destroy()
c. burn()
d. All of these

Answer: d

Explanation:
The Servo library in Arduino doesn’t have any of these functions. Functions like attach(), write(), and detach() are commonly used.

9. Arduino boards are based on which of the following microcontroller/microcontrollers?
Options:
a. ATMEGA328
b. ATMEGA32u4
c. Both (a) and (b)
d. None of these

Answer: c

Explanation:
Different Arduino models use different microcontrollers — Uno uses ATMEGA328, while Leonardo uses ATMEGA32u4.

---

10. What is the clock speed of the Arduino Uno board?
Options:
a. 16MHz
b. 17MHz
c. 8MHz
d. None of these

Answer: a

Explanation:
The standard clock speed for Arduino Uno is 16MHz, providing a balance between speed and power usage.

12. The “Verify” option in the Arduino IDE checks the code for__________.
Options:
a. Compilation errors
b. Improper hardware connection
c. Both (a) and (b)
d. None of these

Answer: a

Explanation:
The “Verify” option compiles your code and checks for syntax or logic errors — it doesn’t check hardware.

---

13. How many pins does the DHT Digital Humidity and Temperature sensor have?
Options:
a. 2
b. 3
c. 4
d. None of these

Answer: c
