When using Auto Scaling, you want to add or remove ECS instances based on the utilization rate of computing resources. For example, you want to remove one ECS instance when the average CPU utilization rate is not greater than 30%. In this case, you need to set the scaling rule ''Remove 1 ECS instance'' and ____________ to finish the configuration.
An event-triggered task is necessary when creating scaling rules based on specific metrics such as CPU utilization. This allows Auto Scaling to monitor real-time metrics and trigger scaling actions when thresholds are met. Scheduled tasks, by contrast, are based on specific times rather than performance metrics.
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 route table is a set of rules that determine how network traffic is routed within a VPC or between different network instances1. 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 VPC1. The default route table contains system routes that are automatically generated by the system based on the network topology1. The system routes cannot be modified or deleted1.
However, you can also create custom route tables for your VPC and add custom routes to them1. Custom routes are manually configured by users to route traffic to specific destinations, such as other VPCs, VBRs, VPN Gateways, or NAT Gateways1. Custom routes can be modified or deleted as needed1. You can also associate VSwitches with different route tables to implement fine-grained routing control1.
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 deleted1.

An enterprise uses a public cloud service to lease several virtual machines and places these virtual machines in an isolated virtual network. They have full control over their virtual network, including choosing their IP address range, specifying the CIDR block, configuring the routing table, and gateway, etc.
In Alibaba Cloud, the _____________ can work as described above.
In Alibaba Cloud, a Virtual Private Cloud (VPC) provides isolated virtual networking environments where users can configure their own IP address ranges, CIDR blocks, routing tables, gateways, and other network elements. This functionality is critical for users who require an isolated, customizable network environment for their virtual machines in the public cloud. SDN (Software-Defined Networking) and NFV (Network Functions Virtualization) are underlying technologies, while VPN offers secure connectivity but not full virtual network management.
A challenging thing in the gaming industry is the unpredictable and fluctuating business traffic. For example, 1 ECS instance is enough to meet all business demands today; however, we may need 10 ECS instances tomorrow.
In this situation, it is difficult to predict the number of ECS instances required. If we use too few ECS instances, we may not be able to cope with business peaks; whereas if we use too many ECS instances, we may introduce unnecessary costs.
On Alibaba Cloud, _______________ is the best product portfolio to cope with the gaming scenario described above.
In this scenario, a combination of Server Load Balancer (SLB), ECS, ApsaraDB for RDS, and Auto Scaling is ideal. SLB distributes incoming traffic across multiple ECS instances, ensuring high availability and reliability. Auto Scaling automatically adjusts the number of ECS instances based on demand, managing costs efficiently by scaling out during peak times and scaling in when demand decreases. ApsaraDB for RDS provides a managed database service that handles increasing database demands without requiring complex manual scaling. This portfolio is optimal for fluctuating gaming traffic as it ensures load balancing, scalability, and cost control.
The difference between public and private Server Load Balancers (SLBs) is that private SLBs connect to their backend ECS instances using the private network (Intranet) while public SLBs connect to their backend ECS instances using the public network (Internet).
The difference between public and private Server Load Balancers (SLBs) is that private SLBs connect to their backend ECS instances using the private network (Intranet) while public SLBs connect to their backend ECS instances using the public network (Internet). This is true according to the Alibaba Cloud documentation on SLB1. Public SLBs are used to distribute traffic from the Internet to ECS instances, while private SLBs are used to distribute traffic within a VPC or a classic network2.
