I passed the Alibaba ACA Cloud1 by drilling Auto Scaling and Server Load Balancer scenarios, especially health checks and scaling triggers. The tricky part was choosing the best architecture option under changing traffic and cost constraints.

I passed the exam and found Auto Scaling questions framed as operational scenarios asking when to use scheduled versus reactive scaling and how cooldowns affect instance counts. Practice calculating thresholds, lifecycle hooks, and CloudMonitor-triggered policies so you can pick the most reliable policy under time pressure.

The ACA Cloud Computing Associate exam leaned heavily on practical ECS and VPC basics, so building a small lab helped me connect security groups, disks, and networking choices. I passed after focusing on how the services fit together rather than memorizing terms.

I passed the ACA Cloud Computing Associate exam and noticed ECS questions often present a small architecture and ask you to choose the right instance family, disk type, and security group rules. Learn instance types, disk choices, snapshot and image workflows, and I'm grateful to Pass4Success for a focused question set that sped my study.

Found the Server Load Balancer session persistence versus health check interaction really confusing on the exam. Sketching the request flow and remembering that an unhealthy backend can break stickiness helped me pick the right answer.

Free Alibaba ACA-Cloud1 Exam Actual Questions

Note: Premium Questions for ACA-Cloud1 were last updated On Jun. 21, 2026 (see below)

Question #1

When using Alibaba Cloud OSS, you can set access control in 3 different levels, which are (Choose three.)

Reveal Solution Hide Solution
Correct Answer: A, B, C

When using Alibaba Cloud OSS, you can set access control in three different levels, which are bucket level, object level, and RAM account level. Bucket level access control is the highest level of access control, which determines whether a user can access the bucket and its objects. Bucket level access control can be set to public read/write, public read, or private. Object level access control is the second level of access control, which determines whether a user can access a specific object in the bucket. Object level access control can be set to inherit from the bucket, public read/write, public read, or private. RAM account level access control is the lowest level of access control, which determines whether a user can perform certain operations on the bucket or the object. RAM account level access control can be set by using RAM policies, which specify the actions, resources, and conditions for the access.Reference:Object Storage Service (OSS) - Alibaba Cloud Academy,Access Control - Alibaba Cloud Documentation Center


Question #2

Cloud disks are reliable because they use_________ to provide block-level data storage for ECS instances, ensuring 99.9999999% data reliability.

Reveal Solution Hide Solution
Correct Answer: A

Cloud disks are reliable because they use adistributed file management system with 3 redundant copiesto provide block-level data storage for ECS instances, ensuring99.9999999% data reliability. This means that the data stored on cloud disks is automatically replicated across three different physical servers in the same zone. If one server fails, the data can still be accessed from the other two servers. Cloud disks also support snapshot backup and recovery, which can help users restore data to a previous point in time in case of accidental deletion or corruption.Reference:Elastic Compute Service (ECS) - Alibaba Cloud Academy, Cloud Disk - Alibaba Cloud Documentation Center

An ECS disk can be used jointly or separately to meet the requirements of different application scenarios. ECS disks are categorized into ephemeral SSD disks and cloud disks. Compared with ephemeral SSD disks, cloud disks are more reliable as they use a triplicate distributed system to provide block-level data storage for ECS instances, ensuring 99.9999999% data reliability.


Question #3

Which of the following scenarios is applicable to use RDS read-only instances?

Reveal Solution Hide Solution
Correct Answer: B

ApsaraDB RDS for MySQL is a cloud-based relational database service that provides secure, cost-effective, and scalable database solutions for various applications. RDS for MySQL supports creating read-only instances that are synchronized with the primary instance in real time. Read-only instances can handle read requests from applications and reduce the read pressure on the primary instance. This can improve the performance and availability of the database system. Read-only instances can also be used for scenarios such as report analysis, data backup, and disaster recovery.

Alibaba Cloud Computing Exam Question 2022

Question #4

Which method is not supported by OSS to create a bucket?

Reveal Solution Hide Solution
Correct Answer: B

ECS instance filesystem directory operation is not a supported method to create a bucket in OSS. A bucket is a container for objects in OSS, and it is not related to the filesystem of an ECS instance.To create a bucket in OSS, you can use one of the following methods1:

through OSS API/SDK: You can use the OSS API or SDK to call the PutBucket operation to create a bucket.The OSS API and SDK support various programming languages, such as Java, Python, PHP, C#, and Node.js2.

through oss cmd tool: You can use the oss cmd tool, which is a command-line tool based on the OSS SDK for Python, to create a bucket by using the ossutil mb command3.

through cloud console: You can use the Alibaba Cloud console to create a bucket by following the steps in the documentation4.Reference:1:Create buckets - Object Storage Service - Alibaba Cloud Documentation Center2:PutBucket - API Reference| Alibaba Cloud Documentation Center3:Create a bucket - OSSUTIL User Guide| Alibaba Cloud Documentation Center4:Create a bucket - Object Storage Service - Alibaba Cloud Documentation Center.


Question #5

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 ''Remove 5 ECS instances'', and creates a scheduled task based on this rule.

And then, the customer checks the scaling group and see it already contains 8 valid ECS instances, he/she then enables this scaling group immediately.

How many ECS instances are left in the scaling group when the scheduled task is activated once?

Reveal Solution Hide Solution
Correct Answer: B

Alibaba Cloud Auto Scaling service allows you to automatically adjust the number of ECS instances in a scaling group based on your business needs and scaling policies.You can set the minimum and maximum number of instances in a scaling group to limit the range of scaling actions1.When you create a scaling rule, you can specify the number of instances to be added or removed, or the expected number of instances after the scaling action2.You can also create a scheduled task to execute a scaling rule at a specified time or periodically3.

In this question, the customer sets the minimum number of instances to 6 and the maximum number of instances to 8 in the scaling group. This means that the scaling group will always have at least 6 instances and at most 8 instances. The customer also adds a scaling rule to remove 5 instances, and creates a scheduled task based on this rule. However, this scaling rule will not be executed if it violates the minimum and maximum limits of the scaling group. Therefore, when the scheduled task is activated once, the scaling group will only remove 2 instances, which is the difference between the current number of instances (8) and the minimum number of instances (6).The remaining number of instances in the scaling group will be 6, which is the correct answer.Reference:1:Create a scaling group - Auto Scaling - Alibaba Cloud Documentation Center2:Create a scaling rule - Auto Scaling - Alibaba Cloud Documentation Center3:Create a scheduled task - Auto Scaling - Alibaba Cloud Documentation Center.
