An online education website is built based on ECS. SLB and Auto Scaling, which greatly reduces resource cost, OandM cost and without compromising system stability and user experience.

Now. the website admin wants to keep the user information (such as source IP, accessed URLs, and duration on each page) for analysis to support their upcoming campaign events In this case, which of the following statements is NOT correct?

A. Let each ECS instance in the scaling group keeps the user access information it processes Thus, the data saved by these ECS instances can be accessed and analyzed at any time, making the solution not only simple, but also efficient reliable, and cost-effective.

B. Save user-related access information to ApsaraDB for RDS in real time or quasi real time, which can then be used for performing query and analysis.

C. Synchronize user-Synchronize user-related access information to ApsaraDB for Memcache in real time or quasi real time. Then, access Memcache using an application or make the data in Memcache persistent based on certain rules and then can use the persistent data for further analysis.

D. Synchronize user-related access information to OSS in real time or quasi real time for further use

Questions 6

When using Alibaba Cloud SLB. you can set different weights for backend ECS instances The higher the weight of a backend ECS instance the more load will be assigned to it An SLB instance has 5 ECS instances in the backend server pool, all of which are healthy Among these 5 ECS instances, the weight of ecs_inst1 is set to 100. Which of the following statements is correct?

A. Based on request level parameters of external requests, all requests with a request level parameter of 100 will be transferred to ecs_inst1

B. Based on SLB's working mechanism, approximately 20% of loads will be assigned to ecs_inst1

C. We do not know the weight settings of the remaining 4 ECS instances, so we cannot tell what would happen

D. 100% of loads will be assigned to ecs__inst1, and the remaining 4 ECS instances will stay idle
