Exam Overview

The CAP-C01 exam typically emphasizes how concepts are used in professional environments, testing both theoretical understanding and practical problem-solving skills.

 

Skills Measured

  • Understanding of core concepts and terminology
  • Ability to apply knowledge to practical scenarios
  • Analysis and evaluation of solution options
  • Identification of best practices and common use cases

 

Preparation Tips

Successful candidates combine conceptual understanding with hands-on practice. Reviewing measured skills and working through scenario-based questions is strongly recommended.

 

Practice Questions for CAP-C01 Exam

The following practice questions are designed to reinforce key CAP-C01 exam concepts and reflect common scenario-based decision points tested in the certification.

Question#1

In an Alibaba Cloud Elastic Compute Service (ECS) instance, you can freely change directory permissions of the system root directory in Linux, which has no influence on all services in the Elastic Compute Service (ECS) instance.

A. TRUE
B. FALSE

Explanation:
Changing directory permissions of the system root directory in Linux can have a significant impact on system functionality and services. Modifying these permissions can lead to restricted access for essential system services, potentially causing service disruptions. Proper care is necessary when altering permissions on critical directories.

Question#2

Alibaba Cloud Content Delivery Network (CDN) is a distributed network that is built and overlaid on the bearer network. It is composed of edge node server clusters distributed across different regions.
CDN acceleration is especially suitable for scenarios where there is significant site traffic and the static resource is repeatedly used by different users. The higher the repeated access rate, the more significant the acceleration effect.

A. TRUE
B. FALSE

Explanation:
Alibaba Cloud CDN is particularly effective for websites with high traffic and static resources that are frequently accessed by different users. In such cases, CDN caching and delivery from edge nodes greatly reduce the load on origin servers and improve access speed for end users, especially in regions closer to the edge nodes.

Question#3

When creating an ECS instance in your Alibaba Cloud VPC, you must specify a VSwitch for that instance at the same time. Otherwise, you will not be able to create this ECS instance.

A. True
B. False

Explanation:
When creating an ECS instance in your Alibaba Cloud VPC, you must specify a VSwitch for that instance at the same time. Otherwise, you will not be able to create this ECS instance. This is true according to the Alibaba Cloud documentation on ECS 1. A VSwitch is a basic network device of a VPC and is used to connect different cloud product instances deployed in a VPC2. A VSwitch defines a network segment within a VPC and allows you to specify the IP address range, network mask, and gateway for the network segment2. When you create an ECS instance, you must select a VSwitch that belongs to the same zone as the ECS instance3. If you do not specify a VSwitch, the ECS instance will not be able to communicate with other cloud product instances in the VPC or access the Internet.

Question#4

RDS instances are automatically created in master-slave mode without any extra costs or associated configuration.

A. TRUE
B. FALSE

Question#5

Once ECS is created, you can't change its private IP address anymore.

A. True
B. False

Explanation:
You can change the private IP address of an ECS instance after it is created, but you need to stop the instance first. The private IP address must be within the CIDR block of the VPC and the VSwitch that
the instance belongs to. You can modify the private IP address of an instance by using the console or the API.

After stopping an Alibaba Cloud Elastic Compute Service (ECS) instance, you will still be charged for some resources related to that ECS instance, such as disks, snapshots, and public IP addresses, until you release them. The charging policy depends on the billing method and network type of the ECS instance. For pay-as-you-go instances, you can choose whether to enable the No fees for stopped instances feature, which allows you to stop paying for vCPUs and memory when the instance is stopped. However, this feature is only available for VPC-connected instances in some regions 1. For subscription instances, you will be charged for the entire subscription period regardless of whether the instance is running or stopped2.
