Question 1
- What capabilities of HUAWEI CLOUD Big Data can help game enterprises perform operational analysis? Multi-select
  
  A : realize multi-dimensional analysis of game users through DLI service, and tap potential value
  
  B : Collect, analyze and process gamer behavior through DIS Flume
  
  C : MRS Flink implements the cleaning and processing of behavioral data
  
  D : Realize user label information storage and query answer through CloudTable
  
  Answer: A,B,C,D
Question 2
- As an architect to design a website up to 100 million times, to achieve high-performance performance in the future, it needs to be achieved through reasonable architecture design. Which of the following describes the elements to consider in the design of a high-performance architecture? (Single).
  
  A :
  You need to consider the bandwidth of the private network, such as whether the HUAWEI CLOUD data center can withstand the traffic generated by 100 million PVs
  
  B :
  Comprehensively consider the overall factors that affect the performance of the architecture, such as /O synchronization, concurrency, resource contention, and large data volume. Often, I/O operations, network responses, poor algorithms, databases, and other inefficient resource usage result in poor performance
  
  C :
  Consider the application itself, such as code execution optimization, software design multi-threading or multi-process
  
  D :
  Fully consider network performance, such as external network access bandwidth, data transmission efficiency, network path, etc.
  
  Answer: A
Question 3
- The cloud-native data lake solution in HUAWEI CLOUD MapReduce provides a leading architecture for separating storage and computing for unstructured data scenarios such as massive government images and videos. Use OBS on the cloud to replace MRS local storage as a big data store. The following description of the OBS service in this solution, which one is wrong? Single selection
  
  A : Replace the EC algorithm with three copies to reduce the unit capacity cost
  
  B : Provide standard storage, low-access storage, and archive storage in three categories
  
  C : Technology needs to be expanded separately
  
  D : Distributed architecture, horizontally scalable
  
  Answer: A
Question 4
- 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
Question 5
- For a critical application, the customer requires the deployment of a fault-tolerant architecture that can achieve RTO=0. Plan to choose C6 2xlarge. 4 types of elastic ECSs, it is estimated that at least 6 ECSs are required for this service. From an architect's point of view, which of the following architectures can meet the above requirements and provide the best overall capabilities? Single selection
  
  A :
  Deploy 6 servers in each of the three zones, and use auto scaling to ensure that nodes can be replaced after damage
  
  B :
  Deploy three servers in each of the two zones and use auto scaling to ensure that nodes can be replaced after they are damaged
  
  C :
  Deploy 6 servers in each of the two zones and use auto scaling to ensure that nodes can be replaced after damage
  
  D :
  Deploy three servers in each of the three zones and use auto scaling to ensure that the can be replaced after the node is damaged
