Question 8

As the number of urban vehicles increases year by year, the problem of parking difficulties is becoming more and more real. Especially for commercial complexes in cities and tourist attraction parking lots with a large flow of people, it is difficult to park and find a car, and it is easy for passengers to cause unnecessary traffic. Congestion, even increased the probability of traffic accidents. It is planned to use HUAWEI CLOUD ROMAComect to transform the management system of the traditional parking lot. After investigation and analysis, the current transformation of the traditional parking lot management system has the following pain points:
Pain point 1: Since most of the traditional parking lots rely on manpower management, it is difficult to grasp the panoramic view of the parking spaces in real time.
Pain point 2: Parking users cannot know the vacant parking spaces in the parking lot in real time, and it takes a lot of time to find a parking space, which further increases the road traffic pressure;
Pain point 3: The transportation department cannot grasp the usage of urban parking spaces in real time, and it is difficult to formulate effective traffic mitigation measures for parking problems.
Assuming you are a Huawei Cloud operation and maintenance expert, in order to solve the above pain points, which of the following measures will you complete the digital transformation of the traditional parking lot management system? (Multiple choice)

A. The parking space sensing device and door gate device of the parking lot are connected to ROMA Connect to realize the reporting of parking space status information

B. By creating a data API, open the parking space status data in the parking lot management system to third-party applications for car owners and city managers to understand the parking space situation

C. Register the device (parking space sensing device, door gate device) on ROMA Connect, and assign a unique ID and password to the device in ROMA Connect, so that the device can be connected to ROMAConnect

D. By configuring the data forwarding rules, forward the device data to the message integration MQS of ROMA Connect, and through the data integration task, convert the data structure of the device data in MQS and write it into the database of the parking lot management system

Correct Answer: A,B,C,D

Question 9
