Object Storage Service (OSS) supports access logging. A bucket owner can activate access logging for their buckets in the OSS management console. When access logging is activated for bucket A, OSS automatically accesses the request logs for this bucket (in hours) and generates and writes an object to the user-specified bucket B according to certain naming rules.
Which of the following
statements is true for OSS logging?
- A . Buckets A and B can be separate buckets (or a single bucket) but they must belong to the same user
- B . Buckets A and B must be the same bucket.
- C . Buckets A and B can belong to different users.
- D . Buckets A and B must be different buckets.
A
Explanation:
OSS logging is a feature that allows you to record the access requests to your OSS buckets. You can enable and configure logging for a bucket in the OSS console or by using the OSS API. When logging is enabled for a bucket A, OSS automatically generates access log objects every hour and stores them in a specified bucket
B. The log objects follow a predefined naming convention that includes the source bucket name, the date, the hour, and a unique string.
The documentation also states that buckets A and B can be separate buckets or the same bucket, but they must belong to the same user 1. This means that you cannot store the access logs of one user’s bucket in another user’s bucket. Therefore, the correct answer is A.

Alibaba Cloud Server Load Balancer (SLB) provides services for distributing traffic among multiple ECS instances. SLB can expand the application system’s service capacity through traffic distribution, and improve the system’s availability by eliminating SPoFs (Single Points of Failure).
Which of the following
statements are correct? (Number of correct answers: 2)
- A . When recreating an SLB instance that has an Internet lp address, a new Internet lP address will be assigned to the SLB instance.
- B . Before using SLB to provide external services, make sure that you have installed and correctly configured the SLB agent on all of the backend ECs instances.
- C . One of SLBs features is the Health Check. f some of the backend ECS instances are down, whereas other backend ECS instances can still provide services, then the system can continue to work normally.

A video company uses SLB to distribute user requests to 20 ECS instances with the same configuration to response these requests. As the Spring Festival approaches, service traffic would double during holidays (based on past experience). Thus, you use Auto Scaling to elastically adjust computing resources. Since the services is online for many years, you have historic records that can help predict the upcoming service traffic and choose the scaling mode freely. In this scenario, which of the following options are feasible and with minimum operation efforts? (Number of correct answers: 2)
- A . Cloud monitor and event-triggered task: Dynamically adds ECS instances during resource shortage and reduces ECS instances during idle hours by monitoring the CPU utilization rate and workload
- B . Scheduled task: Increases the number of ECS instances to 40 on the first day of the holidays and reduce the number to 20 after the holidays.
- C . Manual mode: Set the minimum number of instances to 40 on the first day of the holidays and change the number to 20 after the holidays.
- D . Healthy check mode: Ensures that all the current ECS instances in scaling groups are working correctly to meet user access requests.
AB
Explanation:
According to the Alibaba Cloud Academy, Auto Scaling supports three scaling modes: manual mode, scheduled task, and cloud monitor and event-triggered task. Manual mode requires manual intervention to adjust the number of ECS instances, which is not feasible and with minimum operation efforts. Scheduled task allows you to set the time and number of ECS instances to be added or removed in advance, which is suitable for predictable traffic changes. Cloud monitor and event-triggered task allows you to set the monitoring metrics and thresholds for scaling actions, which is suitable for dynamic traffic changes. Healthy check mode is not a scaling mode, but a feature of SLB to ensure the availability of ECS instances behind the load balancer.

Alibaba Cloud CloudMonitor is a service that monitors Alibaba Cloud resources and Internet functions currently provided by CloudMonitor? (Number of correct answers: 3)
- A . Site monitoring
- B . Customized monitoring
- C . Custom firewall
- D . Operation auditing
- E . Cloud service monitoring
ABE
Explanation:
https://cloudacademy.com/course/alibaba-security-monitoring-1275/introduction-to-cloud-monitor/#:~:text=Cloud%20Monitor%20is%20a%20service,safeguard%20your%20products%20and% 20business.
Option A is correct because site monitoring is one of the functions provided by CloudMonitor. Site monitoring monitors the availability, connectivity, and domain name resolution of sites. It monitors the connectivity and response time of domain names, IP addresses, and ports, and sends alert notifications based on monitoring results1
Option B is correct because customized monitoring is one of the functions provided by CloudMonitor. Customized monitoring allows you to monitor the metrics of your own applications or services. You can use the CloudMonitor API or SDK to report custom metrics to CloudMonitor and view them on the CloudMonitor console. You can also configure alert rules for your custom metrics2
Option E is correct because cloud service monitoring is one of the functions provided by CloudMonitor. Cloud service monitoring monitors the metrics of Alibaba Cloud services, such as Elastic Compute Service (ECS), Object Storage Service (OSS), ApsaraDB for RDS, and Server Load Balancer (SLB). CloudMonitor collects the metrics of these services and displays them on the CloudMonitor console. You can also configure alert rules for these metrics2
Option C is incorrect because custom firewall is not a function provided by CloudMonitor. Custom firewall is a feature of Alibaba Cloud Security Center, which is a different service from CloudMonitor. Security Center provides security protection for your cloud resources and applications. Custom firewall allows you to customize firewall rules for your ECS instances and control the inbound and outbound traffic3
Option D is incorrect because operation auditing is not a function provided by CloudMonitor. Operation auditing is a feature of Alibaba Cloud ActionTrail, which is a different service from CloudMonitor. ActionTrail records the operations performed on your Alibaba Cloud resources and delivers the audit logs to OSS or Log Service for storage and analysis. Operation auditing helps you track the changes of your resources and comply with security standards4

When adopting cloud computing and taking advantage of its convenience, you will also face challenges in information security.
Using cloud computing does not increase security risks, but your active engagement is still a must.
Which of the following is not included in the security principles recommended by Alibaba Cloud?
- A . Users have the same security management responsibility
- B . Users should keep the same data attribution
- C . Users have the same security management standards
- D . Users should keep the same O&M methods
D
Explanation:
In cloud environments, Alibaba Cloud emphasizes that security responsibilities, data ownership (data attribution), and security standards remain with the user. However, O&M (Operations and Maintenance) methods often change due to the distinct management tools, automated processes, and distributed nature of cloud infrastructure. Cloud environments typically use different O&M approaches, so option D is not aligned with Alibaba Cloud’s security principles.
