When creating cloud product instances in Alibaba Cloud, you can choose the default VPC and
VSwitch. The difference between non-default VPC/VSwitch and default VPC/VSwitch is that default VPC and VSwitch can only be created by Alibaba Cloud.
Which of the following statements is incorrect about default VSwitch?
- A . Default VSwitches can only be created in default VPCs
- B . If you have already created a VPC and a VSwitch by yourself, when creating a cloud product instance, the instance cannot be created under the default VSwitch
- C . Default and non-default VSwitches have the same constraints and operations
- D . Default VSwitches are created for you by Alibaba Cloud. Any VSwitches you create are non-default switches
C
Explanation:
Default and non-default VSwitches do not have the same constraints and operations. Default VSwitches have specific configurations and limitations set by Alibaba Cloud, designed to simplify initial setups. In contrast, non-default VSwitches, created by users, allow for more customized configurations and are typically used in more complex or specialized networking environments. Thus, option C is incorrect as the constraints and operations differ between default and non-default VSwitches.

0n an Alibaba Cloud Elastic Compute Service (ECS) instance, if you change the MAC address of the NIC within the operating system, this may result in network connection failure.
- A . TRUE
- B . FALSE
When you create an Alibaba Cloud VPC. a VRouter and a route table will be created automatically.
Which of the following statements is NOT correct about the route table?
- A . Each VRouter may have multiple route tables.
- B . When a VPC is deleted, the corresponding route table is also deleted.
- C . This route table cannot be deleted
- D . The routing entries of the route table can not be modified manually.
D
Explanation:
A route table is a set of rules that determine how network traffic is routed within a VPC or between different network instances 1. A VRouter is a hub that connects all VSwitches in the same VPC and enables communication between them2. When you create a VPC, a VRouter and a default route table are automatically created for the VPC 1. The default route table contains system routes that are automatically generated by the system based on the network topology 1. The system routes cannot be modified or deleted 1.
However, you can also create custom route tables for your VPC and add custom routes to them 1. Custom routes are manually configured by users to route traffic to specific destinations, such as other VPCs, VBRs, VPN Gateways, or NAT Gateways 1. Custom routes can be modified or deleted as needed 1. You can also associate VSwitches with different route tables to implement fine-grained routing control 1.
Therefore, the statement that the routing entries of the route table can not be modified manually is not correct, as it only applies to system routes, not custom routes. The other statements are correct, as each VRouter may have multiple route tables, one default and several custom1; when a VPC is deleted, the corresponding route table is also deleted3; and the default route table cannot be deleted 1.

Recently, response speed of a certain Alibaba Cloud Elastic Compute Service (ECS) instance is unacceptably slow. By using CloudMonitor we discovered that the ECS instance utilizes more than 80% of the assigned bandwidth.
Which of the following approach can address this issue and without the need to reboot the ECS instance?
- A . Upgrade the bandwidth of the ECS instance
- B . None of the above
- C . Upgrade the CPU and memory of the ECS ins
- D . Add a disk to the ECS instance
A
Explanation:
According to the Alibaba Cloud Elastic Compute Service documentation, if the current public bandwidth does not meet your business requirements, you can upgrade or downgrade the public bandwidth configurations without the need to reboot the ECS instance. This can improve the network performance and response speed of the ECS instance. Upgrading the CPU, memory, or disk of the ECS instance may not solve the issue of bandwidth utilization, and may require rebooting the ECS instance.

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?
- A . HTTP
- B . Restful
- C . Web Service
- D . PPPoE
D
Explanation:
PPPoE stands for Point-to-Point Protocol over Ethernet, which is a network protocol that encapsulates PPP frames in Ethernet frames and allows multiple computers to share a single Internet connection. PPPoE is typically used by Internet service providers (ISPs) to provide broadband access to their customers, such as DSL or cable modem. PPPoE is not a protocol that is commonly supported
by Open API for cloud computing service providers, because it is not designed for web-based communication and requires a dedicated connection between the client and the server. Open API, on the other hand, is a term that refers to a set of publicly available application programming interfaces (APIs) that allow developers to access the functionality and data of cloud computing service providers. Open API usually follows standard protocols that are widely used on the web, such as HTTP, Restful, and Web Service. HTTP stands for Hypertext Transfer Protocol, which is the foundation of data communication on the web. HTTP defines how messages are formatted and transmitted, and what actions web servers and browsers should take in response to various commands. HTTP is a stateless protocol, which means that each request is independent and does not depend on any previous requests or responses. Restful stands for Representational State Transfer, which is an architectural style for designing web services that are based on the concept of resources. Restful web services use HTTP methods (such as GET, POST, PUT, and DELETE) to perform operations on resources, and use standard formats (such as JSON or XML) to exchange data. Restful web services are stateless, scalable, and cacheable, and aim to provide a uniform interface for interacting with different types of resources. Web Service is a generic term that refers to any software service that is available over the web and uses a standardized format for communication, such as SOAP or REST. Web Service allows different applications to communicate and exchange data across different platforms and languages. Web Service can be described using a specification language, such as WSDL or OpenAPI, which defines the structure, operations, and parameters of the service. Web Service can also be registered and discovered using a directory service, such as UDDI or Swagger.
