3. Names of the files in each OSS bucket must be unique Also, they can be renamed.

4. All RDS for MySQL backups are full backups.

5. Many websites have suffered DDoS attacks of different volumes. Therefore, accurate understanding of DDoS attacks is critical to website security protection .

Which of the following statements about DDoS attacks is the MOST accurate?

6. If an administrator often needs to manage multiple ECS instances in an Alibaba Cloud VPC through the Internet.

Which of the following solutions can meet this need at low costs and without affecting system security.

7. Which of the following privilege is required to manually install Alibaba Clod Security Center on the server?

8. Company A constructed a sales management platform using three Elastic Compute Service (ECS) instances. One of the instances runs MySQL, and is used as the database server. The other two instances are used as Web servers After some time, the number of employees in Company A dramatically increases, leading to higher sales volumes At the same time, the platform response speed is gradually decreasing too.

According to the report from CloudMonitor, the average CPU utilization rate of the two Web servers exceeds 70%, and database load reaches 75% Company A can select Alibaba Cloud_________ services.to cope with the issue and optimize the performance. (Number of correct answers: 2)

9. SLB is a load balancing service that distributes traffic to multiple cloud servers It provides a wide range of functions to meet the needs of various business scenarios If a user wants to use SLB and ECS instances to deploy two-way authenticated HTTPS websites, the following statement is correct_______.

10. To meet business requirements, a user requires that the backend server of an SLB instance include a primary ECS instance and a secondary ECS instance. When the primary instance is working properly, the traffic is only forwarded to the primary ECS, when the primary instance is down, traffic is switched to the standby instance. In this case, you can create an active/standby server group on the backend of the SLB instance.

Which kind of listener supports this feature? (Number of correct answers: 2)

11. Which of the following scenarios can be done using Alibaba Cloud Express Connection? (Number of correct answers: 2)

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

13. 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.

14. Once ECS is created, you can't change its private IP address anymore.

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

16. 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?

17. If you want to build a secure and isolated network environment on Alibaba Cloud; meanwhile, design your network topology and specify Intranet IP addresses or CIDR Blocks in this network environment as needed, you can choose

18. When creating an ECS instance in your Alibaba Cloud VPC, you must specify a VSwitch for that instance at the same time. Otherwise, you will not be able to create this ECS instance.

19. Which of the following statements is NOT correct, when comparing RDS with a self-built database?

20. Alibaba Cloud Elastic Compute Service (ECS) instances in different Security Groups will definitely have no way to communicate with each other.

21. 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.

22. You would like to deploy your applications on Alibaba Cloud to meet requirements including cost reduction, improving service availability, fast deployment- and redundant backup Alibaba Cloud_________products can help meet these requirements (Number of correct answers 3)

23. 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?

24. Different Alibaba Cloud VPCs are completely isolated from each other.

By default, the VPCs cannot communicate with each other over Intranet, but you can establish VPN connections via the Internet to achieve interconnection between VPCs.

25. 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).
