By using ApsaraDB for RDS to implement read/write splitting, which of the following can be achieved?
(Number of correct answers 2)

  • A. Read/write requests to the database are separated.
  • B. Both read and write requests are distributed to multiple instance
  • C. Read requests are distributed to multiple instances.
  • D. Write requests are distributed to multiple instances.

正解：A、C

解説：
Explanation
ApsaraDB for RDS is a stable and reliable online database service that supports MySQL, SQL Server, PostgreSQL, MariaDB, and PPAS. ApsaraDB for RDS provides a read/write splitting feature that allows you to create read-only RDS instances, which can offload read requests from the primary RDS instance of your database system1. Read/write splitting is implemented by using a dedicated proxy endpoint, which routes read and write requests to different RDS instances based on the SQL statements and the read weights of the read-only instances2. By using ApsaraDB for RDS to implement read/write splitting, you can achieve the following benefits21:
Read requests are distributed to multiple instances. This can improve the read performance and availability of your database system, as well as balance the load among the read-only instances. You can specify the read weights of the read-only instances to control the distribution of read requests.
Read/write requests to the database are separated. This can reduce the pressure on the primary RDS instance and ensure the stability and security of the write operations. You only need to connect to the proxy endpoint, and the proxy will automatically route the read and write requests to the appropriate RDS instances.
The other statements are not correct, as write requests are not distributed to multiple instances, but only sent to the primary RDS instance2; and both read and write requests are not distributed to multiple instances, but separated by the proxy endpoint2. References: [ApsaraDB for RDS - Alibaba Cloud], Read/write splitting - - Alibaba Cloud Documentation Center, Use the read/write splitting feature to increase the processing capability of an ApsaraDB RDS instance

質問 # 59
After activating an Alibaba Cloud Elastic Compute Service (ECS) instance, you want to monitor the status of the ECS instance via Alibaba Cloud console. Therefore: you must activate and purchase Alibaba Cloud CloudMonitor service to meet this demand.

  • A. False
  • B. True

正解：A

解説：
Explanation
You do not need to activate and purchase Alibaba Cloud CloudMonitor service to monitor the status of the ECS instance via Alibaba Cloud console. CloudMonitor is a service that monitors Alibaba Cloud resources and Internet applications. CloudMonitor provides a one-stop, out-of-the-box, and enterprise-class monitoring solution1. CloudMonitor collects monitor metrics of Alibaba Cloud resources and custom metrics and enables you to view and understand the usage of the cloud resources, and the health of your business2. CloudMonitor allows you to monitor the metrics of Alibaba Cloud services, detect the availability of websites hosted on ECS instances or carrier servers, and configure alert rules for specified metrics3. However, CloudMonitor is not a prerequisite for monitoring the status of the ECS instance via Alibaba Cloud console. You can monitor the status of the ECS instance via Alibaba Cloud console without activating and purchasing CloudMonitor service.
You can view the basic information, configuration, security group, and tags of the ECS instance in the console. You can also view the CPU, memory, disk, and network usage of the ECS instance in the console. You can also use the Cloud Assistant feature to run commands on the ECS instance remotely4.


質問 # 60
You are designing a solution for a startup company, the proposed solution is like this You suggest they use ECS instances to process requests from mobile App clients, and use SLB to distribute data traffic and ensure the load across each backend ECS instance is balanced.
Moreover to deal with volatile fluctuations in business volume (page views are much higher on the weekends), you also suggest they use Auto Scaling to dynamically increase or reduce computing resources.
The company is satisfied with the solution you proposed. However, they have one concern that when removing an idle instance from the scaling group: if Auto Scaling shuts the instance down directly, the service running on that instance will be abruptly terminated, resulting in poor user experience.
In order to eliminate your customer's concern, which of the following solutions should you recommend them?

  • A. Find the ECS instance that is going to be removed from the backend server pool of the SLB instance, and manually remove this instance from the backend server pool Applications running on this ECS instance will normally return results, but this instance will not be assigned with new requests.
  • B. Find the ECS instance that is going to be removed from the backend server pool of the SLB instancer and automatically set the weight of this ECS instance to 0. This instance will not be assigned with new requests, and will be automatically removed from the backend server pool after existing tasks are completed.
  • C. First, insert a script into the image for creating the ECS instance Second, make the script run automatically when the operating system in this ECS instances is about to shut down. This script contains the processing logic that can ensure the instance finish all the remaining tasks before shutting down.
  • D. Use the Lifecycle Hook function embedded m Auto Scaling Define a suitable timeout and a web hook to do the necessary work before the instance is removed.

正解：D


質問 # 61
Many cloud computing service providers support users to activate/create a cloud service through Open API.
Which of the following protocols is most not likely to be supported by these Open API?

  • A. PPPoE
  • B. Web Service
  • C. Restful
  • D. HTTP

正解：A

解説：
Explanation
PPPoE stands for Point-to-Point Protocol over Ethernet, which is a network protocol that encapsulates PPP frames in Ethernet frames and allows multiple computers to share a single Internet connection. PPPoE is typically used by Internet service providers (ISPs) to provide broadband access to their customers, such as DSL or cable modem. PPPoE is not a protocol that is commonly supported by Open API for cloud computing service providers, because it is not designed for web-based communication and requires a dedicated connection between the client and the server. Open API, on the other hand, is a term that refers to a set of publicly available application programming interfaces (APIs) that allow developers to access the functionality and data of cloud computing service providers. Open API usually follows standard protocols that are widely used on the web, such as HTTP, Restful, and Web Service. HTTP stands for Hypertext Transfer Protocol, which is the foundation of data communication on the web. HTTP defines how messages are formatted and transmitted, and what actions web servers and browsers should take in response to various commands. HTTP is a stateless protocol, which means that each request is independent and does not depend on any previous requests or responses. Restful stands for Representational State Transfer, which is an architectural style for designing web services that are based on the concept of resources. Restful web services use HTTP methods (such as GET, POST, PUT, and DELETE) to perform operations on resources, and use standard formats (such as JSON or XML) to exchange data. Restful web services are stateless, scalable, and cacheable, and aim to provide a uniform interface for interacting with different types of resources. Web Service is a generic term that refers to any software service that is available over the web and uses a standardized format for communication, such as SOAP or REST. Web Service allows different applications to communicate and exchange data across different platforms and languages. Web Service can be described using a specification language, such as WSDL or OpenAPI, which defines the structure, operations, and parameters of the service. Web Service can also be registered and discovered using a directory service, such as UDDI or Swagger.

  • 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. Incorporate Server Load Balancer (SLB) and add additional ECS instances to relieve the load on existing ECS instances

正解：B、D

解説：
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:

質問 # 67
As a concept stem from cloud computing, cloud storage service provides on-demand storage and data services to users through a unified interface Which of the following characteristics about cloud storage are correct?
(Number of correct answers: 4)

  • A. High scalability Storage capacity can be dynamically scaled to meet the needs.
  • B. High reliability and availability: Provides very high reliability and availability through technologies like
    3 redundant copies, automatic failure recovery, etc.
  • C. Management and maintenance: To prevent emergent service termination, users need to know the underlying detail like how the data is archived in the resource pool.
  • D. Ultra-large scale: Data storage can reach TB or even PB level
  • E. Transparent service: Provides the service through a single SDK
  • F. Service on demand Cloud storage has a huge resources pool, users can apply for and use the resources on demand.

正解：A、B、D、F

解説：
* A. Management and maintenance: To prevent emergent service termination, users need to know the underlying detail like how the data is archived in the resource pool. This is incorrect because cloud storage is designed to abstract the underlying details of how the data is stored and managed from the users. Users do not need to worry about the hardware, software, or network issues that may affect the data availability or reliability. The cloud storage provider is responsible for maintaining and managing the storage infrastructure and ensuring the service continuity1.
* B. Service on demand Cloud storage has a huge resources pool, users can apply for and use the resources on demand. This is correct because cloud storage is based on the cloud computing model of service on demand, which means that users can request and access the storage resources as needed, without having to purchase or provision them in advance. Cloud storage providers offer flexible pricing models that allow users to pay only for the storage they use2.
* C. High reliability and availability: Provides very high reliability and availability through technologies like 3 redundant copies, automatic failure recovery, etc. This is correct because cloud storage uses various technologies and methods to ensure that the data stored in the cloud is always accessible and durable. For example, cloud storage providers typically replicate the data across multiple servers, regions, or zones to prevent data loss due to hardware failure, natural disaster, or human error. Cloud storage providers also use automatic failure recovery mechanisms to detect and repair any issues that may affect the data integrity or availability3.
* D. Ultra-large scale: Data storage can reach TB or even PB level. This is correct because cloud storage can handle massive amounts of data, ranging from terabytes (TB) to petabytes (PB) or even exabytes (EB). Cloud storage providers have the infrastructure and expertise to scale up the storage capacity and performance to meet the growing data needs of users. Cloud storage can support various types of data, such as structured, unstructured, or semi-structured data, and various use cases, such as data backup, data archiving, data analytics, or data sharing.
* E. Transparent service: Provides the service through a single SDK. This is incorrect because cloud storage is not a transparent service, but a service that requires users to interact with it through a specific interface or protocol. Cloud storage providers usually offer different types of storage services, such as object storage, block storage, or file storage, each with its own characteristics and features. Users need to choose the appropriate storage service for their data and use the corresponding software development kit (SDK), application programming interface (API), or command-line interface (CLI) to access and manipulate the data.
* F. High scalability Storage capacity can be dynamically scaled to meet the needs. This is correct because cloud storage is highly scalable, meaning that users can increase or decrease the storage capacity according to their data needs. Cloud storage providers offer elastic storage services that can automatically adjust the storage resources based on the demand, without requiring users to manually provision or deprovision them. Cloud storage also allows users to scale the storage performance, such as throughput, latency, or bandwidth, to optimize the data access and transfer.
