ACP Cloud Computing Certification Questions and Answers

Question 1

Alibaba Cloud Server Load Balancer (SLB) provides services for distributing traffic among multiple ECS instances SLB can expand the application system's service capacity through traffic distribution, and improve the system's availability by eliminating SPoFs (Single Points of Failure). Which of the following statements are correct? (Number of correct answers; 2)

Options:

A.

One of SLB's features is the Health Check. If some of the backend ECS instances are down, whereas other backend ECS instances can still provide services, then the system can continue to work normally.

B.

When recreating an SLB instance that has an Internet IP address, a new Internet IP address will be assigned to the SLB instance.

C.

Before using SLB to provide external services, make sure that you have installed and correctly configured the SLB agent on all of the backend ECS instances.

D.

SLB provides a function to automatically synchronize data among backend ECS instances using rsync remote synchronization.

C.

High reliability and availability: Provides very high reliability and availability through technologies like 3 redundant copies, automatic failure recovery, etc.

D.

Ultra-large scale: Data storage can reach TB or even PB level

E.

Transparent service: Provides the service through a single SDK

F.

High scalability Storage capacity can be dynamically scaled to meet the needs.

Question 3

An online education website is built based on ECS. SLB and Auto Scaling, which greatly reduces resource cost, O&M 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?

Options:

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
