Question 2

A game company recently released a new online game product, which was warmly welcomed by users after its launch.

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

Question 3

Question 4

A state-owned enterprise company is recently undergoing cloud assessment, and the company has put forward requirements for the IT department, requiring that the annual business expenditure be strictly controllable, and no changes are allowed after the budget is determined at the beginning of the year. In addition, the business department also put forward requirements for the IT department, so it is the first time to try to go to the cloud so it will frequently create, delete, change the configuration and other operations of virtual machines, and ensure that these operations are flexible and simple. So which of the following options does IT need to choose to meet these requirements? Multiple selection

A : In the reservation billing model (on-demand package package), the expenditure is determined in advance, and the creation, deletion, and configuration of virtual machines within the reservation scope will not cause cost changes

B : Purchase DeH according to the budget, and then purchase ECS on it, and then create, delete, and change ECS on Dahl without incurring costs

C : Easy-to-use ECS purchase, flexible and can be created and deleted at any time.

D : When purchasing ECS on a package cycle, you can determine a one-year budget in advance to ensure that it does not exceed it

Answer: A,B
