ECS, VPC, and Auto Scaling typically account for a significant portion of the exam because they form the foundation of most Alibaba Cloud deployments. However, all topics are important; the exam tests breadth across all services, so neglecting any area will hurt your score. Focus on understanding how these core services integrate with security, monitoring, and storage services.
In a typical architecture, you create ECS instances within a VPC for network isolation. Auto Scaling automatically adjusts the number of instances based on demand, while Load Balancer distributes traffic across those instances. Security groups and VPC routing control traffic flow, and CloudMonitor tracks performance. Understanding this workflow helps you answer scenario questions correctly and design scalable systems.
Hands-on experience significantly improves exam performance and real-world readiness. Prioritize labs for VPC setup, ECS instance launch and configuration, Auto Scaling group creation, Load Balancer configuration, and security group rules. If time is limited, focus on VPC and ECS first since most other services depend on them. Even 2-3 hours of practical work per topic strengthens your understanding.
Many candidates confuse security group rules with VPC network ACLs, misunderstand Auto Scaling cooldown periods, or overlook CDN cache invalidation requirements. Others struggle with scenario questions because they don't read all options carefully or don't consider cost and availability trade-offs. Review explanations for practice questions to avoid these pitfalls and develop critical thinking skills.
Shift from learning new content to reinforcing weak areas and building speed. Take a full-length timed mock exam to identify remaining gaps, then spend 2-3 days reviewing those topics. Practice scenario-based questions daily to improve decision-making under time pressure. Get adequate sleep the night before the exam and review key definitions and service limits one last time to boost confidence.
If you want to build a secure and isolated network environment on Alibaba Cloud; meanwhile, design your network topology and specify Intranet IP addresses or CIDR Blocks in this network environment as needed, you can choose
According to the Alibaba Cloud VPC documentation1, a virtual private cloud (VPC) is a virtual network dedicated to your Alibaba Cloud account. You have full control over your VPC, such as specifying the CIDR block, configuring route tables and gateways, and creating subnets. A VPC is an isolated network environment that provides security and flexibility for your cloud computing resources. You can use a VPC to build a secure and isolated network environment on Alibaba Cloud, design your network topology, and specify intranet IP addresses or CIDR blocks in this network environment as needed. Therefore, option B is the correct choice for your scenario. Reference: What is a VPC? and Alibaba Cloud Virtual Private Cloud.
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.
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.
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.
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. Reference: Cloud Security- Alibaba Cloud, Security & Compliance Center, Shared Responsibility
If users use Alibaba Cloud Anti-DDoS Basic service, when the attack traffic exceeds the service upper limit, the black hole policy will then be triggered; after that, the users' servers can still provide services at a limited speed.
When the black hole policy is triggered by excessive DDoS traffic, the affected server is temporarily isolated from the network to prevent further damage. During this period, no services are available, meaning the server cannot provide limited-speed services.
A large enterprise wants to migrate the entire business system to Alibaba Cloud to save the overall IT procurement and O&M costs From the security aspect, the company requires that
1. Must support secured remote O&M because the administrator often takes business trips.
2. Networks between subsystems should be isolated because subsystems are independently used by different departments Which of the followings should be used together to meet the company's requirements? (Number of correct answers: 3)
To meet the company's security requirements, the following solutions should be used together:
A . Enable the VPN on the bastion host (or directly use the VPN image on Alibaba Cloud Marketplace). The administrator uses VPN encrypted communication during O&M. This solution can support secure remote O&M, because VPN (Virtual Private Network) is a technology that creates a secure and encrypted connection over the Internet between the bastion host and the administrator's device. VPN can protect the data transmitted between the bastion host and the administrator from being intercepted or tampered by malicious third parties1. Alibaba Cloud provides VPN Gateway service that allows users to create VPN connections between VPCs and on-premises data centers, or between VPCs in different regions2. Users can also use VPN images from Alibaba Cloud Marketplace, such as OpenVPN, to create VPN servers on ECS instances3.
B . Build an independent ECS instance as the bastion host or remote logon and O&M, and authorize the bastion host to access ECS instances running other subsystems. This solution can also support secure remote O&M, because a bastion host is a special-purpose ECS instance that acts as a proxy or a gateway for accessing other ECS instances in the VPC. A bastion host can enhance the security of the ECS instances by limiting the exposure of the ECS instances to the public network, and by implementing security policies and monitoring tools on the bastion host4. Alibaba Cloud provides Bastionhost service that allows users to centrally manage the access to cloud servers from external networks and provide secure connections to VPC resources5.
C . Use the security group function of the ECS instance, and respectively deploy ECS instances running different subsystems to independent security groups. This solution can isolate the networks between subsystems, because a security group is a virtual firewall that controls the inbound and outbound traffic of the ECS instances in the group. Users can configure security group rules to allow or deny access based on the network protocol, port, and source IP address. By deploying ECS instances running different subsystems to independent security groups, users can prevent unauthorized access or communication between the subsystems6.
The other solution is not suitable for the company's scenario, for the following reason:
D . Create multiple ECS instances in the VPC to install subsystems of different departments- Allocate only Intranet IP addresses to all ECS instances, and deploy them in the same security groups. This solution cannot isolate the networks between subsystems, because ECS instances in the same security group can communicate with each other by default, regardless of whether they have intranet or internet IP addresses. Moreover, this solution may also prevent the ECS instances from accessing the internet or providing external services, which may affect the business operation of the company6.
