2022 Realistic Verified ACP-Cloud1 exam dumps Q&As – ACP-Cloud1 Free Update [Q42-Q66]

NO.42 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?

NO.43 Which of the following statements is NOT correct, when comparing RDS with a self-built database?

NO.44 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)

NO.45 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.

NO.46 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.

NO.47 Once ECS is created, you can’t change its private IP address anymore.

NO.48 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?

NO.49 Alibaba Cloud SLB can distribute user requests to backend ECS instances. These ECS instances must have the same specification (CPU, Memory)

NO.50 A large enterprise wants to migrate the entire business system to Alibaba Cloud to save the overall IT procurement and O&M costs From the security aspect, the company requires that
1. Must support secured remote O&M because the administrator often takes business trips.
2. Networks between subsystems should be isolated because subsystems are independently used by different departments Which of the followings should be used together to meet the company’s requirements? (Number of correct answers: 3)

NO.51 All RDS for MySQL backups are full backups.

NO.52 Compared with traditional physical servers, upgrading an ECS instance is much easier. Which of the following statements about upgrading an ECS instance is false?

NO.53 By using ApsaraDB for RDS to implement read/write splitting, which of the following can be achieved? (Number of correct answers 2)

NO.54 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.

NO.55 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)

NO.56 Many of Alibaba Cloud services provide highly reliable 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.

NO.57 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

NO.58 You have created two Alibaba Cloud VPCs in two different regions To establish communication between these two VPCs via the Intranet, you can________.

NO.59 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)

NO.60 After activating an Alibaba Cloud Elastic Compute Service (ECS) instance, you want to monitor the status of the ECS instance via Alibaba Cloud console. Therefore: you must activate and purchase Alibaba Cloud CloudMonitor service to meet this demand.

NO.61 Alibaba Cloud CloudMonitor is a service that monitors Alibaba Cloud resources and Internet functions currently provided by CloudMonitor? (Number of correct answers: 3)

NO.62 You need to create a new ECS instance for a 10-data test. Which of the following billing methods is most cost-effective?

NO.63 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).

NO.64 Alibaba Cloud Object Storage Service (OSS) provides multiple file uploading modes for different scenarios, which are___________.
(Number of correct answers: 2)

NO.65 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?

NO.66 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.
