NEW QUESTION # 12
An online education website is built based on ECS. SLB and Auto Scaling, which greatly reduces resource cost, O&M cost and without compromising system stability and user experience.
Now. the website admin wants to keep the user information (such as source IP, accessed URLs, and duration on each page) for analysis to support their upcoming campaign events In this case, which of the following statements is NOT correct?
- A. Let each ECS instance in the scaling group keeps the user access information it processes Thus, the data saved by these ECS instances can be accessed and analyzed at any time, making the solution not only simple, but also efficient reliable, and cost-effective.
- B. Save user-related access information to ApsaraDB for RDS in real time or quasi real time, which can then be used for performing query and analysis.
- C. Synchronize user-related access information to OSS in real time or quasi real time for further use
- D. Synchronize user-Synchronize user-related access information to ApsaraDB for Memcache in real time or quasi real time. Then, access Memcache using an application or make the data in Memcache persistent based on certain rules and then can use the persistent data for further analysis.
Answer: A
Explanation:
Explanation
This statement is not correct because it is not a good practice to store user access information on each ECS instance in the scaling group. This is because the ECS instances are dynamic and can be added or removed by the Auto Scaling service based on the load and demand. Therefore, the data stored on the ECS instances may be lost or inconsistent if the instances are terminated or replaced. Moreover, this approach does not provide a centralized and unified way to access and analyze the data, which may affect the accuracy and efficiency of the analysis. Therefore, it is better to use other services such as ApsaraDB for RDS, ApsaraDB for Memcache, or OSS to store the user access information in a persistent and scalable manner.

- A. The internal networks of different VPCs are completely isolated and can be interconnected through IP addresses mapped to the outside.
- B. Each VPC has an independent tunnel ID, and a tunnel ID corresponds to a virtualized network.
- C. ECS instances in a VPC use security group firewalls for Layer 2 network access control.
- D. Subnets can be divided like the traditional network environment. Different cloud servers within each subnet are connected by the same router and different subnets are interconnected by switches.
Answer: A,B
Explanation:
Explanation
According to the Alibaba Cloud Academy, a VPC is an isolated network environment that is completely isolated from each other. Each VPC has an independent tunnel ID, and a tunnel ID corresponds to a virtualized network. This means that different VPCs cannot communicate with each other through the tunnel ID. Subnets are not divided like the traditional network environment, but rather are logical divisions of the VPC. Different cloud servers within each subnet are connected by the same router, but different subnets are interconnected by route tables, not switches. ECS instances in a VPC use security group firewalls for Layer 4 network access control, not Layer 2. The internal networks of different VPCs are completely isolated and can be interconnected through IP addresses mapped to the outside, such as NAT Gateway or EIP.

- B. Replace the self-built MySQL database with ApsaraDB for RDS to obtain better database performance, and utilize RDS read-only instances to handle read-only requests
- C. Use Content Delivery Network (CDN) to enhance content loading speed
- D. Import database data into Object Storage Service (OSS) to share the storage pressure on the platform
Answer: A,B
Explanation:
Explanation
Option B is correct because using Server Load Balancer (SLB) and adding additional ECS instances can help to distribute the traffic among multiple servers and improve the availability and scalability of the platform. SLB can also provide health checks and fault tolerance for the ECS instances1 Option D is correct because replacing the self-built MySQL database with ApsaraDB for RDS can provide better database performance, security, and reliability. ApsaraDB for RDS is a fully managed cloud database service that supports MySQL, SQL Server, PostgreSQL, and other engines. It can automatically handle tasks such as backup, recovery, monitoring, and patching. Using RDS read-only instances can also handle read-only requests and reduce the load on the primary database2 Option A is incorrect because importing database data into Object Storage Service (OSS) will not share the storage pressure on the platform. OSS is a cloud storage service that provides high durability, availability, and scalability for storing unstructured data such as images, videos, and documents. It is not suitable for storing structured data such as database tables. Moreover, importing data into OSS will incur additional costs and latency3 Option C is incorrect because using Content Delivery Network (CDN) will not enhance the content loading speed of the platform. CDN is a distributed network that delivers content to users based on their geographic locations, the origin of the content, and the content delivery server. It is mainly used to accelerate the delivery of static content such as images, videos, and scripts. It is not effective for dynamic content such as database queries and transactions4 References:

NEW QUESTION # 32
A customer uses Alibaba Cloud Auto Scaling service and creates a scaling group He/she sets the "Minimum number of instances" to 2 and "Maximum number of instances" to 7.
After correctly configuring scaling settings, the customer adds a scaling rule "Add 6 ECS instances", and creates a scheduled task based on this rule.
And then, the customer checks the scaling group and see it already contains 3 valid ECS instances, he/she then enables this scaling group immediately.
How many ECS instance will be added in the scaling group when the scheduled task is activated once'?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
Explanation
When the scheduled task is activated once, 4 ECS instances will be added in the scaling group. This is because the scaling rule "Add 6 ECS instances" will increase the number of instances in the scaling group to 9, which exceeds the maximum number of instances (7) that is set for the scaling group. Therefore, Auto Scaling will only add 4 ECS instances to reach the maximum number of instances. The remaining 2 ECS instances will not be added to avoid exceeding the quota.
