質問 # 34
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?
- A. We do not know the weight settings of the remaining 4 ECS instances, so we cannot tell what would happen
- B. Based on request level parameters of external requests, all requests with a request level parameter of 100 will be transferred to ecs_inst1
- C. 100% of loads will be assigned to ecs__inst1, and the remaining 4 ECS instances will stay idle
- D. Based on SLB's working mechanism, approximately 20% of loads will be assigned to ecs_inst1
正解：A
解説：
Explanation
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. However, the load distribution is not based on the absolute value of the weight, but on the proportion of the weight in the total weight of all healthy backend ECS instances. For example, if there are two healthy backend ECS instances with weights of 100 and
200 respectively, the first instance will receive 33.3% of the load, and the second instance will receive 66.7% of the load. Therefore, to determine the load distribution of the 5 ECS instances in the question, we need to know the weight settings of the remaining 4 ECS instances. Without this information, we cannot tell what would happen. The other options are incorrect because they are based on wrong assumptions or misunderstandings of the SLB weight setting mechanism.

(Number of correct answers: 2)
- A. Uploading using the API
- B. Upload using the SDK
- C. Directly copying to/from OSS using portable disks
- D. Direct upload from the OSS management console no matter how large the file is
正解：A、B
解説：
Explanation
Alibaba Cloud Object Storage Service (OSS) is a cloud storage service that allows you to store, retrieve, and manage data in the cloud. OSS provides multiple file uploading modes for different scenarios, such as simple upload, multipart upload, append upload, resumable upload, and cross-region replication. These uploading modes can be implemented by using the API or the SDK provided by OSS. Therefore, options B and D are the correct answers. Option A is not correct because the OSS management console only supports simple upload for files that are smaller than 5 GB. Option C is not correct because OSS does not support directly copying to/from OSS using portable disks. References: Object Storage Service:Simple upload, Object Storage Service:Multipart upload, Object Storage Service:OSS tools
質問 # 36
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.
- A. True
- B. False
正解：B
解説：
Explanation
After stopping an Alibaba Cloud Elastic Compute Service (ECS) instance, you will not be charged for the instance usage fee or the public bandwidth fee (if applicable) until you start the instance again. However, you will still be charged for the disk usage fee and the snapshot usage fee (if applicable) regardless of which region the instance is located in. This is because the disks and snapshots are still occupying the storage space and need to be billed accordingly. Therefore, the statement is false. References: 1 - Billing FAQ - Alibaba Cloud Document Center - What fees do I need to pay after I stop a Pay-As-You-Go instance?

- A. 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.
- B. A user request is directed to the server nearest to the customer based on location information of the pre-configured IP section.
- C. 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
- D. The intelligent DNS resolution can parse the same domain name into different IP addresses based on the IP of different visitors.
正解：A
質問 # 38
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.
- A. False
- B. True
正解：B
解説：
Explanation
When using Alibaba Cloud SLB, users can enable the health check function to monitor the availability of the backend ECS instances. If a backend ECS instance A is running abnormally, SLB will stop forwarding requests to it and distribute them to other healthy ECS instances. This way, SLB can ensure the high availability and reliability of the service. When the backend ECS instance A is back to normal, SLB will resume forwarding requests to it. SLB performs health checks on the backend ECS instances at regular intervals and updates their status accordingly. Users can configure the health check parameters such as the protocol, port, interval, timeout, and threshold on the SLB console or by using the API.

質問 # 39
Alibaba Cloud Elastic Compute Service (ECS) instances in different Security Groups will definitely have no way to communicate with each other.
- A. True
- B. False
正解：B
解説：
Explanation
Alibaba Cloud Elastic Compute Service (ECS) instances in different security groups are isolated from each other by default, but they can communicate with each other if the security group rules allow it. A security group is a virtual firewall that controls the inbound and outbound traffic of ECS instances. You can configure security group rules to specify which IP addresses, protocols, and ports can access the ECS instances in a security group. You can also authorize other security groups to access the ECS instances in a security group, which enables cross-security group communication.

質問 # 40
RDS accounts can be used to connect with the databases created on a given RDS instance. Each account can be bound with multiple databases. Yet, the read/write permissions of each database can only be assigned to one RDS account
- A. True
- B. False
正解：B
解説：
Explanation
RDS accounts can be used to connect with the databases created on a given RDS instance. Each account can be bound with multiple databases. However, the read/write permissions of each database can be assigned to multiple RDS accounts, not just one. For example, you can create an account with read-only permission for all databases, and another account with read-write permission for a specific database. This way, you can manage the access control of your databases more flexibly and securely.

質問 # 44
The Alibaba Cloud CDN can directly accelerate access to the files stored in OSS and reduce OSS traffic costs.
- A. False
- B. True
正解：B
解説：
Explanation
The Alibaba Cloud CDN can directly accelerate access to the files stored in OSS and reduce OSS traffic costs.
Alibaba Cloud CDN is a global network of points of presence (POPs) that are distributed across the globe.
Alibaba Cloud CDN serves to reduce back-to-origin traffic. This in turn prevents network congestion and ensures that content is delivered with minimal latency across regions in various use cases1. Alibaba Cloud CDN caches resources from your origin servers on POPs located across the globe. Whenever customers access your resources, the resources are served from the nearest POP instead of the origin server. This helps prevent lengthy back-to-origin requests and reduces loads on origin servers, delivering better experience to your customers and reducing back-to-origin costs1. Alibaba Cloud CDN also provides IPv6 support on some POPs1. You can use Alibaba Cloud CDN to accelerate access to Object Storage Service (OSS). If you directly access OSS resources, the access speed varies based on the region in which the buckets are located and is limited by the outbound bandwidth of OSS2. The Internet traffic cost of CDN is lower than that of OSS, and the back-to-source traffic cost from CDN to OSS is also lower than a user access to OSS directly2. Therefore, using CDN can reduce the traffic cost of OSS. References: Use Alibaba Cloud CDN to accelerate access to OSS, What is Alibaba Cloud CDN?
