Alibaba Cloud VPC utilizes tunneling technology. Each VPC has a unique tunnel ID, and a tunnel ID corresponds to a virtual network. As a result, VPC can achieve a similar isolation effect as that of a traditional VLAN.
- A . TRUE
- B . FALSE
A
Explanation:
Alibaba Cloud VPC uses tunneling technology with unique tunnel IDs to create isolated virtual networks that offer similar isolation capabilities as VLANs in traditional networks. This allows each VPC to function as an independent, secure network environment within the cloud, ensuring traffic separation and resource isolation.

Which of the following features are provided by RDS by default? (Choose three.)
- A . Automatic backup, which supports restoring data to any point in time within the last 15 days
- B . Backup of the master and secondary databases
- C . Dedicated team performing professional O&M on the backend side
- D . Real-time patching for database security vulnerabilities
A, B, C
Explanation:
Alibaba Cloud RDS offers automatic backups (with point-in-time recovery capabilities, usually up to a certain retention period), backup for both primary and secondary databases, and a dedicated team for backend operations and maintenance (O&M). Real-time patching for security vulnerabilities is generally not automatic but is managed as part of periodic updates or urgent patching requirements, making option D incorrect.

An entrepreneur team builds a network disk application based on Alibaba Cloud Products. This application allows users to upload and download files online. Currently, all the files are stored on the data disks of ECS instances. As the service volume increases, the number of ECS instances and overall O&M costs soar. To reduce O&M costs, using the ______________ product in conjunction with ECS instances provides an ideal solution.
- A . SLB
- B . OSS
- C . CDN
- D . ApsaraDB for RDS
B
Explanation:
Alibaba Cloud OSS (Object Storage Service) is designed for storing large volumes of unstructured data, such as files, images, and videos, making it an optimal solution for network disk applications. By migrating storage from ECS data disks to OSS, the team can offload storage tasks, reduce the number of ECS instances required, and significantly lower O&M costs. OSS also provides high scalability, reliability, and cost-effectiveness for such use cases.

Alibaba Cloud Content Delivery Network (CDN) is a distributed network that is built and overlaid on the bearer network. Moreover, it is composed of edge node server clusters distributed across different
regions.
It replaces the traditional data transmission mode, which is centered on Web servers. CDN acceleration is especially suitable for scenarios where there is significant site traffic and the static resource is repeatedly used by different users. The higher the repeated access rate, the more significant the acceleration effect.
- A . TRUE
- B . FALSE
in Alibaba Cloud VPC, the device used for connecting each VSwitch is. (Single answer)
- A . route table
- B . VRouter
- C . ECS
- D . SLB
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
OSS supports deleting buckets. Before deleting a bucket, you must delete all the files in the bucket, including incomplete upload segments.
- A . TRUE
- B . FALSE
A
Explanation:
In Alibaba Cloud OSS, a bucket cannot be deleted until all contents, including files and incomplete multipart upload segments, are removed. This prevents accidental data loss by ensuring no objects remain in the bucket before deletion.

Once ECS is created, you can’t change its private IP address anymore.
- A . True
- B . False
B
Explanation:
You can change the private IP address of an ECS instance after it is created, but you need to stop the instance first. The private IP address must be within the CIDR block of the VPC and the VSwitch that
the instance belongs to. You can modify the private IP address of an instance by using the console or the API.

After stopping an Alibaba Cloud Elastic Compute Service (ECS) instance, you will still be charged for some resources related to that ECS instance, such as disks, snapshots, and public IP addresses, until you release them. The charging policy depends on the billing method and network type of the ECS instance. For pay-as-you-go instances, you can choose whether to enable the No fees for stopped instances feature, which allows you to stop paying for vCPUs and memory when the instance is stopped. However, this feature is only available for VPC-connected instances in some regions 1. For subscription instances, you will be charged for the entire subscription period regardless of whether the instance is running or stopped2.

RDS for MySQL supports cross-zone migration within the same region.
- A . TRUE
- B . FALSE
A
Explanation:
Alibaba Cloud RDS for MySQL supports cross-zone migration within the same region, allowing users to move their RDS instances to different availability zones if needed. This feature helps enhance disaster recovery and flexibility in resource allocation.

When creating an Alibaba Cloud VPC, you must specify Intranet network segments used in the VPC with CIDR Block. This CIDR Block can later be modified after the VPC is created
- A . TRUE
- B . FALSE
