1. By using ApsaraDB for RDS to implement read/write splitting, which of the following can be achieved? (Number of correct answers 2)

2. Alibaba Cloud SLB can distribute user requests to backend ECS instances. These ECS instances must have the same specification (CPU, Memory)

3. When the "'Obtain the Visitor's Real IP Address" function is enabled in Alibaba Cloud SLB For layer 7 services, you can obtain the real IP addresses of visitors through the______________field in HTTP header

4. A video company uses SLB to distribute user requests to 20 ECS instances with the same configuration to response these requests. As the Spring Festival approaches, service traffic would double during holidays (based on past experience). Thus, you use Auto Scaling to elastically adjust computing resources. Since the services is online for many years, you have historic records that can help predict the upcoming service traffic and choose the scaling mode freely.

In this scenario, which of the following options are feasible and with minimum operation efforts? (Number of correct answers: 2)

5. An enterprise hosts their servers (include both Linux and Windows servers) in a traditional IDC Every night hackers with IP addresses from many countries try to crack the password of their servers, making the administrator terribly worried about this However because of work requirements the remote management port of these servers must be opened to public network.

The administrator heard that Alibaba Cloud has solutions that can help customers improve the security of their systems Therefore, he/she wants to migrate the system to Alibaba Cloud .

Which of the following functions should the administrator activate in Alibaba Cloud to reduce the possibility of brute force password cracking?

6. Many of Alibaba Cloud services provide highlyreliable data storage capacity.For example, Object Storage Service (OSS) promises that its data reliability is no less than 99 99999999%. This high data reliability is solely achieved by RAID 0+1 redundancy technology.

7. All RDS for MySQL backups are full backups.

8. 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?

9. If you need to accelerate a certain domain name (such as abc.com) via Alibaba Cloud Content Delivery Network (CDN), you must add it to "CDN Domain Name List" in the CDN service. After added successfully, you will get a CNAME address A Next, you need to modify domain name resolution and direct the domain name (such as abc.com) to CNAME address A .

Which of the following is a NOT correct description of modifying domain name resolution?

10. For ECS and RDS instances under different Alibaba Cloud accounts but in the same region, which of the following statements is NOT correct for migrating self-built MySQL databases (running on ECS) to RDS?

11. 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)

12. Alibaba Cloud Object Storage Service (OSS) is a cloud storage service that features massive capacity, outstanding security, low costs, and high reliability. In an OSS bucket, all elements are stored as________.

13. 1.Alibaba Cloud Content Delivery Network (CDN) performs content acceleration with the support of intelligent DNS resolution. The following function_________is NOT included in intelligent DNS resolution.

14. RDS provides whitelist access policies. You can set permitted IP addresses and IP network segments to effectively prevent hackers from attacking the server by port scanning.

15. The backend server pool of an Alibaba Cloud SLB contains multiple ECS instances, which may have different service capacities.

To exploit the different service capacities of backend ECS instances, which of the following statements is correct?

16. The difference between public and private Server Load Balancers (SLBs) is that private SLBs connect to their backend ECS instances using the private network (Intranet) while public SLBs connect to their backend ECS instances using the public network (Internet).

17. You are designing a solution for a startup company, the proposed solution is like this You suggest they use ECS instances to process requests from mobile App clients, and use SLB to distribute data traffic and ensure the load across each backend ECS instance is balanced.

Moreover to deal with volatile fluctuations in business volume (page views are much higher on the weekends), you also suggest they use Auto Scaling to dynamically increase or reduce computing resources.

The company is satisfied with the solution you proposed. However, they have one concern that when removing an idle instance from the scaling group: if Auto Scaling shuts the instance down directly, the service running on that instance will be abruptly terminated, resulting in poor user experience.

In order to eliminate your customer's concern, which of the following solutions should you recommend them?

18. A startup video streaming company deploys its service on Alibaba Cloud Elastic Compute Service (ECS) Christmas is coming soon and the CEO knows that they need to prepare more computing resources However, they don't want to purchase a large number of Elastic Compute Service (ECS) instances tor a long period of time. Instead, they want to buy ECS instances for a short period of time and release them after the event is over.

Which of the following billing methods of ECS is the most suitable?
