Each account can be bound with multiple databases. Yet, the read/write permissions of each database can only be assigned to one RDS account  True  False QUESTION 24A 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)  Each VPC has an independent tunnel ID, and a tunnel ID corresponds to a virtualized network.  ECS instances in a VPC use security group firewalls for Layer 2 network access control.  Subnets can be divided like the traditional network environment. Different cloud servers within each subnet are connected by the same router and different subnets are interconnected by switches.  The internal networks of different VPCs are completely isolated and can be interconnected through IP addresses mapped to the outside. QUESTION 25Before data communication is setup, the security groups match the security group rules one by one to query whether to allow access requests Assume that the user has created two security group rules 1 and 2 The protocol type, port range, authorization type, and authorization object of the two security group rules are the same. The difference is that Rule 1 is a denial policy, rule 2 is an allowed policy, so the following statement is correct_______ (Number of correct answers 2)  If rule 1 and rule 2 have the same priority, the rule of the denial policy takes effect first, and the rule of the allowed policy does not take effect  If rule 1 and rule 2 have the same priority, the rule of the allowed policy takes effect first, and the rule that of the denial policy does not take effect.  If rule 1 and rule 2 have different priorities, the rule with a small priority number takes effect  If rule 1 and rule 2 have different priorities, the rule with a large priority number takes effect. QUESTION 26Different 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.  True  False QUESTION 27Which of the following statements is NOT correct, when comparing RDS with a self-built database?  RDS requires no O&M while self-built database require a dedicated DBA for maintenance, which results in high HR costs.  RDS provides automatic backup while self-built databases require you to prepare storage space for backup copies and regularly verify that these copies can be restored.  RDS features a high availability of 99 95% while self-built databases require you to implement data protection primary-standby replication, and RAID all by yourself.  Self-built database support quick deployment and elastic scaling. QUESTION 28To 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.

Which of the following protocols is most not likely to be supported by these Open API?  HTTP  Restful  Web Service  PPPoE QUESTION 32The 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?  Choose Weighted Round Robin mode to set higher weights to ECS instances with higher capacities The higher the weight of the backend ECS instance the higher chance that the instance will receive requests.  SLB cannot assign more requests to certain ECS instances.  Choose Round-Robin model and ECS instances with higher capacities will surely be assigned with more requests.  Choose Weighted Least-Connection mode, and ECS instances with higher capacities will surely be assigned with more requests. QUESTION 33You 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)  Create a scaling rule  Create a scheduled task.  Create a new scaling group.  Create an event-triggered task. QUESTION 34Alibaba Cloud Elastic Compute Service (ECS) instances in different Security Groups will definitely have no way to communicate with each other.  True  False QUESTION 35Many 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.  True  False QUESTION 36OSS supports multi-part uploading for large files, namely dividing a large file into multiple parts and uploading them in order. This function is suitable for scenarios such as uploading large files or uploading files with poor connectivity.After completing all the multi-part uploading tasks, if you forget to invoke the “Complete Multipart Upload” interface, there will be fragment files left in OSS, occupying bucket storage space-To facilitate deleting those files, OSS provides the________function.  OpenAPI batch deletion  Online batch deletion  Bucket clearing  Fragment management QUESTION 37Alibaba 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.  A user request is directed to the server nearest to the customer based on location information of the pre-configured IP section.  The intelligent DNS resolution can parse the same domain name into different IP addresses based on the IP of different visitors.  The intelligent DNS resolution supports web page content caching. A user will receive data from the origin site at first-time access, and then will be reading data from cache in subsequent requests  If a user activates mirror sites in different IDCs, intelligent DNS resolution can achieve load balancing by guiding customers in different places to different mirror sites. QUESTION 38Auto 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?  The instance and the scaling group must be in the same region and zone.  The instance and the scaling group must be in the same region but not necessarily the same zone.  Each scaling group can span up to two regions. After adding the ECS instance, the number of regions of all the ECS instances in the scaling group must be no greater than two.  The instance and the scaling group can be in different regions and zones. QUESTION 39After 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.  True  False QUESTION 40SLB 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_______.  SLB can only host SSL certificates, not CA certificates.  You need to host server SSL certificates and client CA certificates on SLB  SLB can only host CA certificates, not SSL certificate  SLB can only support HTTPS one-way authentication QUESTION 41An 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.
