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.

You need to create a new ECS instance for a 10-data test. Which of the following billing methods is most cost-effective?
According to the Alibaba Cloud ECS documentation1, the Pay-As-You-Go billing method is flexible and suitable for short-term or uncertain workloads. However, it is also the most expensive option compared to other billing methods. To reduce the cost of Pay-As-You-Go instances, you can purchase a Savings Plan, which is a discount plan that offers lower prices for a fixed amount of hourly usage. A Savings Plan can be applied to any Pay-As-You-Go instance in the same region, regardless of the instance type, operating system, or zone. Therefore, option A is the most cost-effective billing method for a 10-day test, as it allows you to enjoy the flexibility of Pay-As-You-Go and the savings of a fixed commitment. Reference: Billing methods and Savings Plan.
Which of the following Alibaba Cloud products can provide Anti-DDoS service? (Choose two.)
Alibaba Cloud provides two main products for Anti-DDoS protection: Anti-DDoS Origin Service, which protects against attacks at the origin server level, and Anti-DDoS Pro Service, which offers advanced DDoS mitigation for applications hosted on Alibaba Cloud. Security Center and Cloud Firewall offer different security functionalities but do not provide direct Anti-DDoS services.
Which of the following is not a potential cause of latency on an RDS read-only instance?
Latency on an RDS read-only instance can be caused by high loads on the instance itself, inadequate instance specifications, or excessive write operations on the master instance, as these factors directly impact replication delay and resource contention. However, a high load on the ECS instance connected to the RDS read-only instance would not inherently cause latency on the RDS instance, as the ECS and RDS operate independently in terms of processing.
