ECS, RDS, and security services typically account for a larger portion of exam questions because they are core to most production deployments. However, all seven topic areas are tested, so balanced preparation across all domains is essential. Focus extra study time on ECS configuration, RDS high availability, and security best practices, but do not neglect Auto Scaling, Load Balancer, and OSS fundamentals.
In a typical three-tier application, ECS instances run your application code, Server Load Balancer distributes incoming traffic across multiple instances, and Auto Scaling automatically adds or removes instances based on demand. CloudMonitor tracks CPU and memory metrics, triggering Auto Scaling policies when thresholds are breached. Understanding these interconnections helps you answer scenario-based questions and design resilient architectures.
Hands-on experience significantly strengthens exam performance because it builds intuition for service behavior and configuration. Prioritize labs that cover launching and configuring ECS instances, setting up Auto Scaling groups, configuring a Server Load Balancer, and creating RDS database instances with backups. If time is limited, focus on ECS and RDS labs first, as these services appear most frequently in exam scenarios.
Many candidates confuse RDS backup types or misunderstand Auto Scaling policy triggers, leading to incorrect scenario answers. Others overlook security details such as security group rules or IAM permissions, which are frequently tested. Avoid rushing through questions; read each scenario carefully, identify what is being asked, and eliminate obviously wrong answers before selecting your choice.
In your final week, focus on reviewing questions you previously answered incorrectly and re-reading explanations for topics where you scored below 80 percent. Take one more full-length practice test to identify any remaining gaps, then spend the remaining days drilling scenario-based questions and practicing your pacing. Avoid learning entirely new material in the final days; instead, reinforce what you have already studied.
__________feature in Server Load Balancer means that it can forward the access requests from a single user to the same ECS instance within a certain period to ensure session continuity.
Session persistence feature in Server Load Balancer means that it can forward the access requests from a single user to the same ECS instance within a certain period to ensure session continuity. This feature is useful for applications that require users to maintain a stateful connection with the backend servers, such as online shopping or banking. Session persistence can be enabled by configuring a cookie timeout period or a source IP hash method in the Server Load Balancer console.Reference:ACA Cloud Computing Certification - Alibaba Cloud Academy,Server Load Balancer - Alibaba Cloud Academy, Session Persistence - Alibaba Cloud Documentation Center
A/An is a copy of data on a disk at a certain point in time.
A snapshot is a copy of data on a disk at a certain point in time. It is used to back up and restore data, or create custom images.Snapshots can capture the data of system disks, data disks, and shared block storage devices1.
You can create a custom image for ECS using which of the followings? (Choose two.)
You can create a custom image for ECS using data disk snapshots or system disk snapshots. A snapshot is a backup of the data on a disk at a specific point in time. You can use snapshots to create custom images, which are copies of the operating system and applications on a disk.You can use custom images to create ECS instances that have the same operating system, applications, and data as the original disk12.
You cannot create a custom image for ECS using CPU snapshots or memory snapshots. These are not valid terms in Alibaba Cloud.CPU and memory are not persistent storage devices, and they do not store the operating system and applications that are required for creating a custom image34.Reference:1: Create a custom image from a snapshot - Alibaba Cloud12: What is a custom image?- Alibaba Cloud23: What is a CPU?- Alibaba Cloud34: What is memory?- Alibaba Cloud4
In which of the following cases would you need to apply an ICP license? (Choose three.)
An ICP license is a permit issued by the Chinese Ministry of Industry and Information Technology (MIIT) that allows websites to operate in China. An ICP license is required for any website that is hosted on a mainland China server, or that wants to use a China-based CDN service to accelerate its access in China. Therefore, you would need to apply an ICP license in the following cases:
Accelerate your Overseas Website in China: If you have a website that is hosted outside of China, but you want to use Alibaba Cloud's CDN service to improve its performance and user experience in China, you would need to apply an ICP license for your domain name. This is because Alibaba Cloud's CDN nodes are located in mainland China, and any website that uses them must comply with the Chinese regulations.
Launch your website in China: If you want to host your website on an Alibaba Cloud ECS instance or OSS bucket that is located in mainland China, you would need to apply an ICP license for your domain name. This is because any website that is hosted on a mainland China server must have an ICP license to be accessible and legal in China.
Launch your online shop in China: If you want to run an e-commerce website that sells goods or services to customers in China, you would need to apply an ICP license for your domain name. This is because any website that engages in commercial activities in China must have an ICP license to operate legally and securely in China.
Alibaba Cloud provides anti-DDoS products of different levels. If the service availability needs to be kept at 99.9% or higher under DDoS attacks, which of the following is the MOST suitable product?
Alibaba Cloud provides anti-DDoS products of different levels to protect your applications and data from DDoS attacks. Among them, Anti-DDoS Service Pro is the most suitable product for ensuring high service availability under DDoS attacks.Anti-DDoS Service Pro is a proxy-based mitigation service that diverts network traffic to the Alibaba Cloud global anti-DDoS network through DNS resolution, mitigates volumetric DDoS attacks and resource exhaustion DDoS attacks, and ensures the stability and availability of your origin servers1.Anti-DDoS Service Pro provides the following features and benefits2:
