When creating an ECS instance in your Alibaba Cloud VPC, you must specify a VSwitch for that instance at the same time. Otherwise, you will not be able to create this ECS instance.
- A . True
- B . False
A
Explanation:
When creating an ECS instance in your Alibaba Cloud VPC, you must specify a VSwitch for that instance at the same time. Otherwise, you will not be able to create this ECS instance. This is true according to the Alibaba Cloud documentation on ECS 1. A VSwitch is a basic network device of a VPC and is used to connect different cloud product instances deployed in a VPC2. A VSwitch defines a network segment within a VPC and allows you to specify the IP address range, network mask, and gateway for the network segment2. When you create an ECS instance, you must select a VSwitch that belongs to the same zone as the ECS instance3. If you do not specify a VSwitch, the ECS instance will not be able to communicate with other cloud product instances in the VPC or access the Internet.

By using ApsaraDB for RDS to implement read/write splitting, which of the following can be achieved? (Number of correct answers 2)
- A . Write requests are distributed to multiple instances.
- B . Read requests are distributed to multiple instances.
- C . Read/write requests to the database are separated.
- D . Both read and write requests are distributed to multiple instance
BC
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 system 1. 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.

Company F launched a new App and put the installation package (size: 6 MB) on its official website (hosted on Elastic Compute Service (ECS)). Initially, the download speed was acceptable. However, due to an advertising event on CCTV last week, the number of installation package downloads drastically increased, resulting in poor user experience and a significant increase in ECS bandwidth cost.
Company F can select Alibaba Cloud ______________ service to solve download speed and
bandwidth cost problems at the same time.
- A . Object Storage Service (OSS) + Content Delivery Network (CDN)
- B . Object Storage Service (OSS) + Auto Scaling
- C . Object Storage Service (OSS) + ApsaraDB for RDS
- D . Auto Scaling + Elastic Compute Service (ECS) instance
A
Explanation:
To handle high download traffic efficiently, Company F can use Object Storage Service (OSS) to store the installation package and Content Delivery Network (CDN) to distribute it. OSS provides scalable, low-cost storage, while CDN caches content at edge nodes, reducing the load on the ECS instance and improving download speeds for users. This combination helps control bandwidth costs on ECS and provides faster download speeds by serving content closer to end-users.

Alibaba Cloud CloudMonitor allows you to customize monitoring metrics and alert policies.
Which of the following statements about customized monitoring are correct? (Number of correct answers:2)
- A . Users can monitor concerned services and report collected monitoring data to CloudMonitor, so that cloudMonitor processes the data and generates alerts according to the result.
- B . Users can only select limited and fixed templates, and monitor specified server performance indicators.
- C . The number of customized monitoring metrics is limited, and programs used to report metric data must be deployed on the Alibaba Cloud server.
- D . The number of customized monitoring metrics is not limited, and programs used to report metric data may be deployed on devices other than the Alibaba Cloud server.
After activating an SLB, it will be assigned an IP address. The SLB will keep this IP address until it is released.
- A . TRUE
- B . FALSE
In an Alibaba Cloud Elastic Compute Service (ECS) instance, if you subscribe to the SELINUX service in Linux, this will not affect the monitoring feature in the ECS management console.
- A . TRUE
- B . FALSE
A
Explanation:
Enabling SELinux on an ECS instance does not interfere with Alibaba Cloud’s ECS monitoring features. SELinux is a security module that enforces mandatory access controls on Linux systems. It operates independently from the monitoring capabilities provided by the ECS console, so ECS metrics and monitoring functions remain unaffected when SELinux is enabled.

RDS instances are automatically created in master-slave mode without any extra costs or associated configuration.
- A . TRUE
- B . FALSE
Alibaba Cloud SLB provides certificate upload and management services. You can bind the required certificate when creating a Listener. When using ___________ protocol, is a certificate mandatory?
- A . HTTPS
- B . HTTP
- C . TCP
- D . PPPoE
A
Explanation:
Certificates are mandatory when using the HTTPS protocol with Alibaba Cloud SLB to secure data transmission between clients and the SLB instance. HTTPS (HTTP Secure) requires an SSL/TLS certificate to encrypt the data, ensuring secure communication over the network. For protocols like HTTP or TCP, a certificate is not required, as they do not natively support encryption.

Many websites have suffered DDoS attacks of different volumes. Therefore, accurate understanding of DDoS attacks is critical to website security protection.
Which of the following statements about DDoS attacks is the MOST accurate? (Single answer)
- A . DDoS attacks primarily target databases.
- B . DDoS attacks crack the server’s logon password by means of a massive number of attempts.
- C . The main purpose of a DDoS attack is to prevent the target server from providing normal services. Currently the DoS attack is one of the strongest and most indefensible website attacks.
- D . The purpose of a DDoS attack is to steal confidential information.
Alibaba Cloud SLB can help distribute traffic among multiple backend servers.
Which of the following statements is correct about backend servers?
- A . The backend servers can only be Alibaba Cloud ECS instances
- B . All servers that can be accessed through the Internet are supported
- C . Supports all cloud products in Alibaba Cloud
- D . Supports AWS EC2
A
Explanation:
Alibaba Cloud Server Load Balancer (SLB) is designed to distribute incoming network traffic across multiple ECS instances within Alibaba Cloud, enhancing fault tolerance and application reliability. Backend servers for SLB must be Alibaba Cloud ECS instances, as SLB is specifically optimized to work within the Alibaba Cloud ecosystem. While it does not support instances from other cloud providers, it ensures integration and performance with Alibaba Cloud’s ECS instances.
