Alibaba Cloud OSS is a cloud storage service that features massive capacity, outstanding security, low cost, and high reliability. To control access to files stored on OSS, OSS provides multiple access permissions for each bucket. These bucket permissions are _______________. (Choose three.)
- A . Private-read
- B . Public-read-write
- C . Public-read
- D . Private
B, C, D
Explanation:
Alibaba Cloud OSS provides three primary access permissions for buckets: Private, Public-read, and Public-read-write.
Private: Only the owner has access to read or write data.
Public-read: The owner can read and write, but others can only read.
Public-read-write: The bucket is fully open for reading and writing by all users.
There is no Private-read permission in OSS access control options, so option A is incorrect.

When using ECS, you don’t have to stop the ECS instance before resizing the system disk.
- A . TRUE
- B . FALSE
Auto Scaling is a management service that can automatically adjust elastic computing resources based on your business needs and policies. This service can automatically adjust. (Single answer)
- A . Number of ECS instances
- B . CPU for ECS instances
- C . Memory size for ECS instances
- D . Bandwidth for ECS instances
A route table refers to the list of routing entries on a VRouter in Alibaba Cloud VPC. You can create/delete any route tables in VPC.
- A . TRUE
- B . FALSE
Alibaba Cloud SLB includes these components: external service requests, Listener, Load Balancer, Backend Server, etc.
Which of the following statements is correct about Listeners? (Single answer)
- A . Listener includes SLB policies and forwarding rules.
- B . Listener is a collection of ECS instances that provide external services.
- C . Listener refers to an SLB instance.
- D . By configuring monitoring rules, Listener can generate monitoring indexes for SLB.
Auto Scaling is a management service that can automatically adjust elastic computing resources based on your business needs and policies It supports adding an existing ECS instance into the scaling group but imposes certain requirements on instance region In this case, which of the following statements is true?
- A . The instance and the scaling group must be in the same region and zone.
- B . The instance and the scaling group must be in the same region but not necessarily the same zone.
- C . Each scaling group can span up to two regions. After adding the ECS instance, the number of regions of all the ECS instances in the scaling group must be no greater than two.
- D . The instance and the scaling group can be in different regions and zones.
B
Explanation:
According to the Alibaba Cloud documentation1, Auto Scaling is a service that automatically adjusts the number of elastic computing resources based on your business demands and policies. When the demand for computing resources increases, Auto Scaling automatically adds ECS instances to ensure sufficient computing capabilities. When the demand decreases, Auto Scaling automatically removes ECS instances to reduce costs.
Auto Scaling supports adding an existing ECS instance into the scaling group, but the instance must meet some requirements 1. One of the requirements is that the instance and the scaling group must be in the same region. However, they do not have to be in the same zone. A zone is a physical area within a region that has independent power grids and networks. A region is a geographic area where Alibaba Cloud deploys its resources. Therefore, the correct answer is B.

In Auto Scaling, the cool-down time of a scaling group refers to the lockout period after a scaling activity has been executed successfully.
Which of the following statements about cool down time are true? (Number of correct answers: 2)
- A . During the cool-down time, only the scaling activities in the same scaling group are locked.
- B . You can’t skip a scaling group’s cool-down time period anyway right after a scaling activity is just finished.
- C . When multiple ECS instances are added or removed from a scaling group, the cool-down time begins only when the last instance has been added or removed from the scaling group.
- D . During the cool-down time of a scaling group, only the alarms from CloudMonitor can bypass the cool-down time and trigger scaling activities, whereas others will still subject to the cool-down time, such as the manually triggered scaling activities.
Alibaba Cloud Server Guard provides brute-force password cracking protection. Therefore, users who have activated Server Guard neither need to modify the administrator password of their ECS instances periodically nor need to set a complicated password.
- A . TRUE
- B . FALSE
B
Explanation:
Even with Alibaba Cloud Server Guard enabled, it is still recommended to periodically change
passwords and use complex passwords to improve security. Server Guard provides additional protection but is not a substitute for strong password practices.

Alibaba Cloud SLB can distribute user requests to backend ECS instances. These ECS instances must have the same specification (CPU, Memory).
- A . TRUE
- B . FALSE
The difference between public and private Server Load Balancers (SLBs) is that private SLBs connect to their backend ECS instances using the private network (Intranet) while public SLBs connect to their backend ECS instances using the public network (Internet).
- A . True
- B . False
A
Explanation:
The difference between public and private Server Load Balancers (SLBs) is that private SLBs connect to their backend ECS instances using the private network (Intranet) while public SLBs connect to their backend ECS instances using the public network (Internet). This is true according to the Alibaba Cloud documentation on SLB 1. Public SLBs are used to distribute traffic from the Internet to ECS instances, while private SLBs are used to distribute traffic within a VPC or a classic network2.
