NEW QUESTION # 25
Your website has high volume of traffic and sudden spikes for a very short time. In this scenario, can manage traffic peak efficiently and maintain a consistent user experience.
- A. RDS
- B. Auto Scaling
- C. VPC
- D. Server Load Balancer
Answer: B
Explanation:
Explanation
Auto Scaling is a service that automatically adjusts computing resources based on your volume of user requests. When the demand for computing resources increases, Auto Scaling automatically adds ECS instances to serve additional user requests, or alternatively removes instances in the case of decreased user requests1. Auto Scaling can help you manage traffic peaks efficiently and maintain a consistent user experience by scaling up or down your ECS instances according to your predefined policies and business needs2. References: 1: Auto Scaling: Automatically Adjusts Computing Resources - Alibaba Cloud2: Overview - Auto Scaling - Alibaba Cloud Documentation Center.
NEW QUESTION # 26
Multiple lower-configuration I/O-optimized ECS instances can be used with to deliver a high- availability architecture.
- A. Auto Scaling
- B. Server Load Balancer
- C. OSS
- D. RDS
Answer: B
NEW QUESTION # 27
Which of the following statements is wrong when comparing RDS with self-built database?
- A. RDS requires no O&M while self-built database requires a dedicated DBA for maintenance, which results in high HR cost.
- B. Self-built database supports quick deployment and elastic scaling.
- C. RDS features a high availability of 99.95% while self-built database requires you to implement data protection, primary-standby replication, and RAID all by yourself.
- D. RDS provides automatic backup while self-built database requires you to prepare storage space for backup copies and regularly verify that these copies can be restored.
Answer: B
Explanation:
Explanation
ApsaraDB RDS is a cloud-based relational database service that provides secure, cost-effective, and scalable database solutions for various applications. RDS has many advantages over self-built databases, such as high availability, automatic backup, and easy O&M. One of the statements that is wrong when comparing RDS with self-built database is that self-built database supports quick deployment and elastic scaling. This is not true, because self-built database requires users to purchase, install, and configure hardware and software by themselves, which can be time-consuming and complex. Moreover, self-built database cannot easily adjust the computing and storage resources according to the business needs, which can lead to over-provisioning or under-provisioning. RDS, on the other hand, supports quick deployment and elastic scaling, because users can create, modify, or delete RDS instances in minutes through the console or API. Users can also scale up or down the RDS instance specifications, storage capacity, or network bandwidth without affecting the business continuity.

NEW QUESTION # 30
You can create a custom image for ECS using which of the followings? (Choose two.)
- A. Memory snapshot
- B. Data disk snapshot
- C. CPU snapshot
- D. System disk snapshot
Answer: B,D
Explanation:
Explanation
You can create a custom image for ECS using data disk snapshots or system disk snapshots. A snapshot is a backup of the data on a disk at a specific point in time. You can use snapshots to create custom images, which are copies of the operating system and applications on a disk. You can use custom images to create ECS instances that have the same operating system, applications, and data as the original disk12.
You cannot create a custom image for ECS using CPU snapshots or memory snapshots. These are not valid terms in Alibaba Cloud. CPU and memory are not persistent storage devices, and they do not store the operating system and applications that are required for creating a custom image34.

NEW QUESTION # 37
A company wants to use Alibaba Cloud service to replace their self-built database, which of the following services should it choose?
- A. AsparaDB for RDS
- B. Deploy more ECS instances
- C. Alibaba Cloud CDN (Content Delivery Network)
- D. Server Load Balancer (SLB)
Answer: A
Explanation:
Explanation
A company wants to use Alibaba Cloud service to replace their self-built database, which of the following services should it choose? The best answer is ApsaraDB for RDS, which is a stable, reliable, cost-effective, and scalable online database service that supports most mainstream database engines, including MySQL, SQL Server, PostgreSQL, PPAS (highly compatible with Oracle), and MariaDB1. ApsaraDB for RDS is based on the Apsara Distributed File System and high-performance SSDs of Alibaba Cloud, and provides various features such as backup and recovery, performance monitoring, security, and disaster recovery2. By using ApsaraDB for RDS, the company can reduce the complexity and cost of database management, and focus on their core business.
The other options are not suitable for replacing a self-built database. Server Load Balancer (SLB) is a service that distributes traffic among multiple ECS instances according to the configured forwarding rules. It can be used to balance the load and improve the service availability and fault tolerance of applications3. Alibaba Cloud CDN (Content Delivery Network) is a service that delivers content from origin servers to edge nodes, and accelerates the response to user requests. It can be used to improve the user experience and reduce the bandwidth consumption of origin servers4. Deploying more ECS instances is a way to increase the computing resources and scalability of applications, but it does not provide a database service5.

NEW QUESTION # 38
Cloud disks are reliable because they use_________ to provide block-level data storage for ECS instances, ensuring 99.9999999% data reliability.
- A. a distributed file management system with 3 redundant copies
- B. a file system
- C. a double copy distributed system
- D. a Linux file system
Answer: A
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.

- A. snapshot download
- B. snapshot deletion
- C. snapshot duplicate
- D. snapshot rollback
Answer: A,C
Explanation:
Explanation
According to the Alibaba Cloud Academy, a cloud disk snapshot is a point-in-time backup of a cloud disk.
You can use snapshots to back up data, create images, or restore data. The operations that you can do on a cloud disk snapshot are snapshot creation, snapshot deletion, snapshot rollback, and snapshot sharing.
Snapshot duplicate and snapshot download are not the operations that you can do on a cloud disk snapshot.
Therefore, the options A and C are the correct answers. References: Snapshot Overview - Alibaba Cloud Documentation Center, ACA Cloud Computing Exam Preparation Course - Alibaba Cloud, Module 3: Cloud Computing Storage, Lesson 2: Snapshot, Slide 2
