A customer uses Alibaba Cloud Auto Scaling service and creates a scaling group. He/she sets the "Minimum number of instances" to 6 and "Maximum number of instances" to 8.After correctly configuring scaling settings, the customer adds a scaling rule "Adjust to 10 ECS instances " and creates a scheduled task based on this rule. And then, the customer checks the scaling group and see it already contains 6 valid ECS instances, he/she then enables this scaling group immediately.
How many ECS instance will be in the scaling group when the scheduled task is activated once? (Single answer)
- A . 8
- B . 10
- C . 6
- D . 5
Alibaba Cloud ECS is a simple and efficient computing service. ECS helps you quickly deploy applications, improve your 0&M efficiency, and reduce IT cost. ECS belongs to this type of service_______.(Single answer)

- B . PaaS (Platform as a Service)
- C . IaaS (Infrastructure as a Service)
- D . DaaS (Data as a Service)
Which of the following statements is true for Alibaba Cloud RDS? (Single answer)
- A . Multiple databases can be created for one instance.
- B . Databases with the same name are allowed to be hosted on the same instance.
- C . Physical host CPU and Memory resource are not shared among the common type of RDS instances.
- D . All editions of RDS support HA mode.
In traditional IT scenarios, it is very difficult to achieve 99.99999999% data reliability for massive data storage and avoid SPOF (Single Point of Failure) at the same time. In Alibaba Cloud, the
________________ service supports the features described above.
- A . SLB
- B . ApsaraDB for RDS
- C . OSS
- D . CDN
C
Explanation:
Alibaba Cloud OSS (Object Storage Service) provides extremely high data reliability, typically around 99.99999999%, due to its multi-replica and distributed architecture, ensuring data durability and resilience against single points of failure (SPOF). OSS is designed to store massive amounts of data with high redundancy, making it a preferred choice for businesses that require high reliability and fault tolerance in cloud storage.

Different Alibaba Cloud VPCs are completely isolated from each other.
By default, the VPCs cannot communicate with each other over Intranet, but you can establish VPN connections via the Internet to achieve interconnection between VPCs.
- A . True
- B . False
B
Explanation:
Different Alibaba Cloud VPCs are completely isolated from each other by default, but they can communicate with each other over the intranet by using different methods, such as Cloud Enterprise Network (CEN), VPN gateways, VPC peering connections, and PrivateLink. These methods allow you to establish secure and reliable connections between VPCs without exposing your network traffic to the internet.

When using Alibaba Cloud SLB, users can enable the health check function. Layer-4 SLBs (TCP protocol) determine the availability of ECS instances through_____________. (Single answer)
- A . Whether the 3-way handshake can be established between the backend ECS instance and the SLB
- B . Special characters contained in the message returned from backend ECS instances
- C . Status codes returned from backend ECS instances
- D . Length of message returned from backend ECS instances
Alibaba Cloud provides comprehensive security protection covering networks, hosts, applications, databases, and content for on-cloud clients. Users using Alibaba Cloud services only need to focus on their own services, without the need to pay any attention to security protection issues.
- A . True
- B . False
B
Explanation:
Alibaba Cloud provides comprehensive security protection covering networks, hosts, applications, databases, and content for on-cloud clients, but users still need to pay attention to security protection issues. Alibaba Cloud and its customers are jointly responsible for the security of customers’ applications built on Alibaba Cloud. With security responsibilities shared between Alibaba Cloud and its customers, Alibaba Cloud provides a secure infrastructure to decrease the enterprise security burden of customers. As such, customers can configure and use cloud products in a secure manner, thus relieving much of the underlying security burdens while allowing customers to focus more on their core business needs. However, customers still need to follow the best practices and guidelines for cloud security, such as using strong passwords, enabling multi-factor authentication, encrypting sensitive data, applying security patches, etc. Customers also need to monitor and manage the security risks and incidents of their cloud environment using Alibaba Cloud’s security products and services, such as Security Center, ActionTrail, Cloud Firewall, etc.

You need to create a new ECS instance for a 10-data test.
Which of the following billing methods is most cost-effective?
- A . Pay-AS-You-Go with Savings Plan
- B . Preemptible
- C . Subscription
- D . Pay-As-You-Go
A
Explanation:
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.

Alibaba Cloud OSS is a cloud storage service that features massive capacity, outstanding security, low cost, and high reliability. For a website consisting of static pages, they can use OSS to host these static pages. Meanwhile, using OSS in conjunction with ___________ product for acceleration purposes.
- A . ECS
- B . CDN
- C . VPC
- D . Container Service
B
Explanation:
Alibaba Cloud CDN (Content Delivery Network) can be used with OSS to accelerate the delivery of static content by caching data at edge nodes closer to end-users. This combination is ideal for static websites, as CDN reduces latency and enhances the loading speed of web pages hosted on OSS. By serving content from multiple distributed nodes, CDN provides users with faster, more efficient access to static resources.
