Question 2

An enterprise customer needs to deploy a new service on the cloud due to business expansion. The system deployed this time does not have high requirements for the continuity of the web side and application applications, and can be recovered half an hour after the failure. The system has high data security requirements and requires a data loss tolerance of less than 30 seconds. As an operations implementer for the company, which of the following methods should you deploy? Multiple selection

A : The amount of new service access is not large, according to the service access, the WEB side and application can be deployed on a single machine, and the new cloud host can be re-applied to resume business after the failure

B : Data backup is required for new service data security considerations. WEB TERMINALS AND APPLICATIONS CAN BE BACKED UP BY HOST BACKUP OR IMAGE PACKAGING. The database is backed up at the same time as a highly available deployment

C : With the needs of business development, business needs to expand. THE WEB SIDE AND THE APPLICATION ARE SCALED HORIZONTALLY, AND THE DATABASE IS VERTICALLY EXPANDED

D : Business systems have high requirements for databases, and primary/standby instances can be deployed from the perspective of high availability to ensure data reliability

Answer: B,C,D

Question 3

When migrating applications to the cloud there are many factors that affect the migration efficiency. When using an online migration solution, the most important factors affecting migration efficiency include migration network bandwidth and network quality, the performance of source and destination hosts, the time period during which the migration work is carried out, the types of migration services, the types of migration databases, and migration tools. Judgment

A : True

B : False

Answer: A

Question 4

A game company customer needs to build a real-time leaderboard. use Pu b/Sub to implement instant chat rooms, and deploy dynamic servers for the "Moments of Friends" released by newer players The account server is used to save basic user information, and the friend server is used to persistently store massive and complex player networks. Which of the following HUAWEI CLOUD database products can be used to meet these requirements?

Question 5

A game company recently released a new online game product, which was warmly welcomed by users after its launch. However, during the evening rush hour, users often log in congestion and cannot access the system normally, and the user experience feedback is poor. The company asked to resolve this issue quickly, and as the company's IT architect, which of the following would be the appropriate solution? Multiple selection

A : Performance can be scaled by adding more servers to the load-balanced network so that accepted requests can be distributed to different back-end systems according to policy

B : Replace one large resource with multiple small resources to reduce the impact of a single failure on the entire system

C : Build the system on the cloud's dynamically scalable architecture that supports a good user experience and streaming Growth in volume or data size does not degrade performance

D : Interdependencies in the system should be reduced. allowing various components to pass only through specific. technology-independent interfaces (e.g., RES TFUL API). Interact with each other. Technical implementation details are hidden so that the underlying implementation can be modified without affecting other components

Answer: A,B,C,D
