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.
What is the full name of ECS?
Elastic Compute Service (ECS) is an IaaS offering on Alibaba Cloud that provides high-performance, stable, reliable, and scalable compute capacity in the cloud. ECS eliminates your need to invest in hardware up front. You can create as many or as few instances as you need in response to changes in requirements or popularity of your workloads. With an ever-growing selection of instance types, ECS provides broader and deeper choices to match a wide spectrum of computing needs.Reference:What is ECS? - Alibaba Cloud
SQL injection is a common application layer attack, usually through building special input parameters and pass it to web applications to steal or sabotage the application dat
a. Which of the following is the target for SQL injection?
SQL injection is a common application layer attack that targets the database of a web application. SQL injection exploits a security vulnerability in the application's software, such as incorrect filtering of user input, that allows an attacker to send malicious SQL statements to the database.These statements can then be executed to steal, modify, or delete data, or even execute commands on the server1.SQL injection can also bypass authentication and authorization mechanisms, and sometimes even impersonate or damage the underlying system2.SQL injection is one of the most common and dangerous web attacks, and it can cause serious damage to the confidentiality, integrity, and availability of web applications3.Reference:1:SQL Injection - OWASP2:SQL Injection - Web Application Firewall - Alibaba Cloud Documentation Center3:Web Application Firewall:What is WAF? - Alibaba Cloud.
You can retrieve data directly from an ECS Image and use it right away.
An ECS image is a copy of data from one or more disks that are attached to an ECS instance. You cannot retrieve data directly from an ECS image and use it right away. You need to create an ECS instance from the image first, and then access the data on the disks of the instance.Reference:Elastic Compute Service:Image overview
Which of the following statements is true for RDS?
RDS allows users to create multiple databases in one RDS instance, as long as the total storage capacity and performance of the instance are not exceeded. This can help users save costs and simplify management. Users can create, delete, and manage databases in the RDS console or by using SQL commands. However, databases with the same name are not allowed in the same instance, and resources are shared among the databases in the same RDS instance, such as CPU, memory, disk, and network bandwidth.Reference:Operate and Manage a Relational Database on the Cloud,Alibaba RDS Course | Cloud Academy,ACA Cloud Computing Certification - Alibaba Cloud Academy
Your website has oscillating traffic peaks that are difficult to predict in advance. In this scenario, it is recommended to use SLB and together with ECS.
Your website has oscillating traffic peaks that are difficult to predict in advance. In this scenario, it is recommended to use SLB and Auto Scaling together with ECS. SLB is a service that distributes traffic among multiple ECS instances according to the configured forwarding rules. It can be used to balance the load and improve the service availability and fault tolerance of applications. Auto Scaling is a service that automatically adjusts computing resources based on your volume of user requests. When the demand for computing resources increases, Auto Scaling automatically adds ECS instances to serve additional user requests, or alternatively removes instances in the case of decreased user requests.By using SLB and Auto Scaling together with ECS, you can achieve high scalability and elasticity for your website, and cope with the changing traffic patterns12.Reference:1: ACA Cloud Computing Exam Preparation Course - Alibaba Cloud32: Auto Scaling: Automatically Adjusts Computing Resources - Alibaba Cloud4
