An enterprise built an isolated network environment by using Alibaba Cloud VPC, and connected this VPC and a traditional data center via VPN. As a result, this enterprise can seamlessly migrate data from its traditional data center to Alibaba Cloud.
Now they need to receive user requests from the Internet, and assign these requests to multiple ECS instances inside the VPC by using SLB. Which of the following statements are correct? (Choose two.)

  • A. They can create an SLB instance in the VPC, and mount ECS instances within the VPC to this SLB instance. And then use a jump server to receive external requests, and direct these requests to SLB to forward them to backend ECS instances.
  • B. They can create an SLB instance with an Internet IP address, and mount ECS instances within the VPC to this SLB instance. The public SLB will be used to receive external requests. As a result, requests from the Internet will be transferred to backend ECS instances within the VPC.
  • C. They can create an SLB instance in the VPC, and mount ECS instances within the VPC to this SLB instance. And then, bind an EIP to the SLB, so that this SLB instance can receive requests from the Internet, and assign these requests to the backend ECS instances.
  • D. They can create an SLB instance with an Internet IP address, and mount ECS instances within the VPC and servers of the traditional data center to this SLB instance. The public SLB will be used to receive external requests. As a result, requests from the Internet will be transferred to backend ECS instances within the VPC and servers of the traditional data center.


Answer : BC

Alibaba Cloud Server Load Balancer (SLB) provides service for distributing traffic among multiple ECS instances. SLB can expand the application system’s service capacity through traffic distribution, and improve the system’s availability by eliminating SPoFs (Single Points of Failure). Which of the following statements are correct? (Choose three.)

  • A. When recreating an SLB instance that has an Internet IP address, a new Internet IP address will be assigned to the SLB instance.
  • B. Before using SLB to provide external services, make sure that you have installed and correctly configured the SLB agent on all of the backend ECS instances.
  • C. One of SLB’s features is the Health Check. If some of the backend ECS instances are down, whereas other backend ECS instances can still provide the service, then the system can continue to work normally.
  • D. SLB provides a function to automatically synchronize data among backend ECS instances using rsync remote synchronization technology.
