NEW QUESTION # 13
Company A builds a sales management platform based on Alibaba Cloud services, using 3 ECS instances. One of the ECS instance has MySQL installed as the database server of the platform, the other two are used as WEB servers. After some time, due to the rapid increase of employees and sales analysis requests, the performance of the platform is challenged in terms of response time. Through CloudMonitor, it is found that the average CPU usage reaches 70% for the two WEB server ECS instances and the database load reaches
75% for the database server ECS instance. In this situation, company A may choose which Alibaba Cloud services to improve the performance. (Choose two.)
- A. Import data into OSS to share the storage load of the platform.
- B. By adding a SLB instance and increase the number of ECS instances to reduce the work load on current ECS instances.
- C. Use content delivery network, CDN, to accelerate the caching of the platform's css, JavaScript files etc.
- D. Use RDS to replace existing self-built database, in order to obtain better database performance; also creating RDS read-only instances to handle read-only requests, hence reduce the work load on master RDS instance.
Answer: C,D
Explanation:
Explanation
A and C are the correct answers because they can improve the performance of the platform by reducing the load on the ECS instances and the database server.
A is correct because using CDN can accelerate the delivery of static content such as CSS and JavaScript files, which can reduce the bandwidth consumption and latency of the ECS instances. CDN can also cache the content in edge nodes closer to the end users, which can improve the user experience and response time of the platform1 C is correct because using RDS can replace the existing self-built database, which can provide better database performance, reliability, security, and scalability. RDS can also handle the backup, recovery, monitoring, and maintenance of the database, which can reduce the management overhead and cost of the platform. Moreover, creating RDS read-only instances can handle read-only requests, which can reduce the workload on the master RDS instance and improve the database availability and performance23 References: 1: CDN Overview 2: RDS Overview 3: RDS Read-only Instances

NEW QUESTION # 16
When we talk about the 'Elastic' feature for ECS product, we are not talking about.
- A. Elastic Administration
- B. Elastic Computing
- C. Elastic Network
- D. Elastic Storage
Answer: A
Explanation:
Explanation
Elastic Computing Service (ECS) is a cloud computing service that provides scalable, on-demand computing resources for cloud applications. ECS offers elastic computing, elastic storage, and elastic network features to meet different business needs. However, ECS does not provide elastic administration, which means that the management and configuration of ECS resources are not automatically adjusted according to the workload or demand. Users need to manually create, modify, or delete ECS instances, disks, snapshots, security groups, and other resources. Users can also use other Alibaba Cloud services, such as Auto Scaling, Server Load Balancer, and Cloud Monitor, to enhance the elasticity and availability of ECS.

NEW QUESTION # 17
Cloud disks are reliable because they use_________ to provide block-level data storage for ECS instances, ensuring 99.9999999% data reliability.
- A. a Linux file system
- B. a file system
- C. a distributed file management system with 3 redundant copies
- D. a double copy distributed system
Answer: C
Explanation:
Explanation
Cloud disks are reliable because they use a distributed file management system with 3 redundant copies to provide block-level data storage for ECS instances, ensuring 99.9999999% 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. References: 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.

NEW QUESTION # 19
Which of the following statements is true for RDS?
- A. None of the above is true.
- B. Multiple databases can be created in one RDS instance.
- C. Resources are not shared among the databases in the same RDS instance.
- D. Databases with the same name are allowed in the same instance.
Answer: B
Explanation:
Explanation
RDS allows users to create multiple databases in one RDS instance, as long as the total storage capacity and performance of the instance are not exceeded. This can help users save costs and simplify management. Users can create, delete, and manage databases in the RDS console or by using SQL commands. However, databases with the same name are not allowed in the same instance, and resources are shared among the databases in the same RDS instance, such as CPU, memory, disk, and network bandwidth.

NEW QUESTION # 24
A video streaming company uses SLB to distribute user requests to 30 ECS instances (the 30 ECS instances have the same configuration). Yet, the company finds that the service traffic soars dramatically every night from 20:00 to 02:00. According to their calculation, the evening traffic is 100% higher than the traffic in other periods of time. To properly respond to user requests, which of the following methods is most preferred from the perspective of cost and implementation simplicity?
- A. Configure Auto Scaling appropriately to automatically add or reduce ECS instances.
- B. Manually create 30 ECS instances using the custom image, and then add them to SLB every night before 20:00 and remove them after 02:00.
- C. Configure Auto Scaling appropriately to automatically upgrade/downgrade the ECS instances.
- D. Create 30 ECS instances based on the custom image and add them to SLB. Then, configure weights for these ECS instances to respond to user requests every night from 20:00 to 02:00, and reset those weights to zero for other periods of time.
Answer: A
Explanation:
Explanation
According to the Alibaba Cloud Academy, Auto Scaling is a service that automatically creates and releases ECS instances based on pre-defined rules in order to scale services to match demand. Furthermore, it can configure server load balancer and relational database service white lists, without any manual intervention.
Therefore, using Auto Scaling is the most preferred method from the perspective of cost and implementation simplicity, as it can dynamically adjust the number of ECS instances according to the traffic fluctuations, without requiring manual operations or wasting resources. The other methods are either too complex, inefficient, or costly to implement.
