Q29. 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?

Q30. 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________.

Q31. A company launched its online service just a year ago. It uses five ECS instances and does not have a full-time system administrator Over the last six months, the company’s system has encountered various security problems Several high-risk vulnerabilities were exploited by hackers, leading to leakage of the company’s confidential dat
a. Which of the following Alibaba Cloud products can be used to quickly resolve this problem?

Q32. When using Alibaba Cloud SLB to forward layer 7 (HTTP) service requests. SLB will replace the IP address in the HTTP header file to forward requests.
Therefore the source IP address that can be seen on the backend ECS instance is the IP address of SLB instead of the clients real IP address.

Q33. 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?

Q34. 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).

Q35. 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?

Q36. When using Alibaba Cloud SLB, users can enable the health check function If a backend ECS instance A is running abnormally, SLB will isolate it and forward the requests to other ECS instances, and when the backend ECS instance A is back to normal, SLB will again forward requests to it.

Q37. Many cloud computing service providers support users to activate/create a cloud service through Open API. Which of the following protocols is most not likely to be supported by these Open API?

Q38. Names of the files in each OSS bucket must be unique Also, they can be renamed.

Q39. You are using Auto Scaling with one scaling group already created, then you want to execute a task at a specific time such as removing 1 ECS instance every night at 00:00. To achieve this, which of the following operations should be performed’? (Number of correct answers; 2)

Q40. You need to create a new ECS instance for a 10-data test. Which of the following billing methods is most cost-effective?

Q41. Alibaba Cloud SLB can distribute user requests to backend ECS instances. These ECS instances must have the same specification (CPU, Memory)

Q42. Auto Scaling is a management service that can automatically adjust elastic computing resources based on your business needs and policies It supports adding an existing ECS instance into the scaling group but imposes certain requirements on instance region In this case, which of the following statements is true?

Q43. Once ECS is created, you can’t change its private IP address anymore.

Q44. After stopping an Alibaba Cloud Elastic Compute Service (ECS) instance, since the ECS instance is stopped, you will not be charged for anything related to that ECS instance until you start the instance again regardless of which region the instance is located in.

Q45. A Virtual Private Cloud (VPC) is an isolated network environment that is completely isolated from each other The following statements about VPC are correct_________. (Number of correct answers: 2)

Q46. By using ApsaraDB for RDS to implement read/write splitting, which of the following can be achieved? (Number of correct answers 2)

Q47. Auto Scaling can automatically adjust the number of ECS instances based on user-defined scaling rules to meet service needs. If a user cannot predict service changes or does not have enough history data, he/she can still use dynamic scaling mode to automatically add/remove ECS instances based on certain CloudMonitor performance metrics (such as the CPU utilization rate)

Q48. 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?

Q49. As a concept stem from cloud computing, cloud storage service provides on-demand storage and data services to users through a unified interface Which of the following characteristics about cloud storage are correct? (Number of correct answers: 4)

Q50. 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.

Q51. 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.

Q52. 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.

Q53. 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)
