Question 2:Which statement accurately compares MongoDB and MySQL in the context of IoT data management?

A

MongoDB is a document-oriented Non-relational database, while MySQL is a Relational Database Management System (RDBMS).

B

MySQL is more efficient than MongoDB in handling large volumes of IoT data due to its structured query language.

C

MongoDB and MySQL both use the same data storage format and are equally efficient in handling IoT data.

D

Both MongoDB and MySQL are primarily used for cloud-native applications only.

Question 3: What is the primary advantage of using Node.JS in server-side IoT data management?

Node.JS is favored for its event-driven, asynchronous programming suitable for network services.

B

It is the only programming language that supports database management.

C

Node.JS is the most resource-efficient programming language available.

D

It is mainly used for its compatibility with SQL databases.

Question 4: According to the section, what was a significant finding in the research comparing SQL and NoSQL DBMSs based on IoT data structure?

A

The hybrid database model using MongoDB and MySQL showed improved performance over using MySQL alone.

B

NoSQL databases were found to be less efficient in handling IoT data compared to SQL databases.

C

SQL databases always outperformed NoSQL databases in all metrics.

D

The experiments conclusively proved that MongoDB is the only viable option for IoT data management.

Question 5: What is the primary objective of the experiments proposed in this paper?

A

To evaluate and compare the performance of SQL and NoSQL databases on IoT data.

B

To design a new type of database system specifically for IoT applications.

C

To determine the cost-effectiveness of different IoT devices.

D

To analyze the security aspects of IoT data management.

Question 6: Which of the following is NOT a part of the three main parts of the evaluation conducted in the experiments?

A

Assessing the environmental impact of IoT data management.

B

Proposing a prediction model for database latency estimation.

C

Examining the impact of increasing workloads on databases.

D

Testing the effect of cloud instance capabilities on database performance.

Question 7: In the context of this paper, how is the pollution database modified for use in the experiments?

A

By partitioning the database into sensors, location coordinates, and timestamp parts.

B

By limiting the database to indoor air pollution data only.

C

By integrating image and audio data with sensor data.

D

By adding more sensor types and increasing data redundancy.

Question 8. What distinguishes the MongoDB setup from the MySQL setup in these experiments?

A

MongoDB and MySQL both use referential integrity constraints in the same way.

B

Only MySQL is capable of handling the IoT sensor data efficiently.

C

MongoDB exclusively uses SQL for data management, while MySQL does not.

D

MongoDB uses reference, embedded, and hybrid models for data set management, which is not the case with MySQL.

Question 9. What was a key finding regarding the performance of MySQL and MongoDB under increasing workloads?

A

MySQL and MongoDB both showed similar performance degradation under increasing workloads.

B

Neither MySQL nor MongoDB showed any performance changes under increasing workloads.

C

Increasing workloads led to a greater loss in performance for MongoDB compared to MySQL.

D

MySQL exhibited a greater loss in performance compared to MongoDB under increasing workloads.

B

The reference model.

C

All models showed equal efficiency.

D

The hybrid model.

Question 11. In the context of estimating database latency, how did the two regression models compare?

A

Both Linear and Non-linear Regressions were equally effective.

B

Non-linear Regression was more effective than Linear Regression.

C

Linear Regression was found to be more accurate than Non-linear Regression.

D

The paper did not compare Linear and Non-linear Regression models.

Question 12. What is suggested as future work in the paper?

A

Focusing only on improving the performance of MongoDB.

B

Discontinuing the use of MySQL in favor of more advanced databases.

C

Limiting the comparison to small-data workloads only.

D
