Recently, response speed of a certain Alibaba Cloud Elastic Compute Service (ECS) instance is unacceptably slow. By using CloudMonitor we discovered that the ECS instance utilizes more than 80% of the assigned bandwidth.
Which of the following approach can address this issue and without the need to reboot the ECS instance?
- A. Upgrade the bandwidth of the ECS instance
- B. None of the above
- C. Add a disk to the ECS instance
- D. Upgrade the CPU and memory of the ECS ins
正解：A
解説：
Explanation
According to the Alibaba Cloud Elastic Compute Service documentation, if the current public bandwidth does not meet your business requirements, you can upgrade or downgrade the public bandwidth configurations without the need to reboot the ECS instance. This can improve the network performance and response speed of the ECS instance. Upgrading the CPU, memory, or disk of the ECS instance may not solve the issue of bandwidth utilization, and may require rebooting the ECS instance.

質問 # 32
When the "'Obtain the Visitor's Real IP Address" function is enabled in Alibaba Cloud SLB For layer 7 services, you can obtain the real IP addresses of visitors through the______________field in HTTP header
- A. X-Forwarded-For
- B. Connection
- C. Etag
- D. Authorization
正解：A
解説：
Explanation
The X-Forwarded-For field in HTTP header is used to identify the originating IP address of a client connecting to a web server through an HTTP proxy or a load balancer. When the "Obtain the Visitor's Real IP Address" function is enabled in Alibaba Cloud SLB, the SLB instance adds the X-Forwarded-For field to the HTTP header of each request and forwards the request to the backend server. The backend server can then obtain the real IP address of the visitor from the X-Forwarded-For field1. The format of the X-Forwarded-For field is as follows:
X-Forwarded-For: client, proxy1, proxy2
where the value is a comma+space separated list of IP addresses, the left-most being the original client, and each successive proxy that passed the request adding the IP address where it received the request from. In this example, the request passed through proxy1, proxy2, and then the SLB instance (proxy3).2 References: Obtain client IP addresses - Server Load Balancer - Alibaba Cloud, X-Forwarded-For - MDN Web Docs
質問 # 33
The Alibaba Cloud CDN can directly accelerate access to the files stored in OSS and reduce OSS traffic costs.
- A. True
- B. False
正解：A
解説：
Explanation
The Alibaba Cloud CDN can directly accelerate access to the files stored in OSS and reduce OSS traffic costs.
Alibaba Cloud CDN is a global network of points of presence (POPs) that are distributed across the globe.
Alibaba Cloud CDN serves to reduce back-to-origin traffic. This in turn prevents network congestion and ensures that content is delivered with minimal latency across regions in various use cases1. Alibaba Cloud CDN caches resources from your origin servers on POPs located across the globe. Whenever customers access your resources, the resources are served from the nearest POP instead of the origin server. This helps prevent lengthy back-to-origin requests and reduces loads on origin servers, delivering better experience to your customers and reducing back-to-origin costs1. Alibaba Cloud CDN also provides IPv6 support on some POPs1. You can use Alibaba Cloud CDN to accelerate access to Object Storage Service (OSS). If you directly access OSS resources, the access speed varies based on the region in which the buckets are located and is limited by the outbound bandwidth of OSS2. The Internet traffic cost of CDN is lower than that of OSS, and the back-to-source traffic cost from CDN to OSS is also lower than a user access to OSS directly2. Therefore, using CDN can reduce the traffic cost of OSS. References: Use Alibaba Cloud CDN to accelerate access to OSS, What is Alibaba Cloud CDN?
質問 # 34
When using Alibaba Cloud SLB to forward layer 7 (HTTP) service requests. SLB will replace the IP address in the HTTP header file to forward requests.
Therefore the source IP address that can be seen on the backend ECS instance is the IP address of SLB instead of the clients real IP address.
- A. True
- B. False
正解：A
解説：
Explanation
When using Alibaba Cloud SLB to forward layer 7 (HTTP) service requests, SLB will replace the IP address in the HTTP header file to forward requests. Therefore, the source IP address that can be seen on the backend ECS instance is the IP address of SLB instead of the client's real IP address. However, SLB also provides a feature called X-Forwarded-For (XFF) that can help you obtain the real IP address of the client. XFF is a standard HTTP header field that records the original IP address of the client and the proxy servers that the request passes through. You can enable XFF on the SLB console or by using the API, and then configure your backend ECS instance to parse the XFF header field and get the real IP address of the client.

- B. The intelligent DNS resolution can parse the same domain name into different IP addresses based on the IP of different visitors.
- C. If a user activates mirror sites in different IDCs, intelligent DNS resolution can achieve load balancing by guiding customers in different places to different mirror sites.
- D. A user request is directed to the server nearest to the customer based on location information of the pre-configured IP section.
正解：C

質問 # 38
When you create an Alibaba Cloud VPC. a VRouter and a route table will be created automatically. Which of the following statements is NOT correct about the route table?
- A. This route table cannot be deleted
- B. When a VPC is deleted, the corresponding route table is also deleted.
- C. Each VRouter may have multiple route tables.
- D. The routing entries of the route table can not be modified manually.
正解：D
解説：
Explanation
A route table is a set of rules that determine how network traffic is routed within a VPC or between different network instances1. A VRouter is a hub that connects all VSwitches in the same VPC and enables communication between them2. When you create a VPC, a VRouter and a default route table are automatically created for the VPC1. The default route table contains system routes that are automatically generated by the system based on the network topology1. The system routes cannot be modified or deleted1.
However, you can also create custom route tables for your VPC and add custom routes to them1. Custom routes are manually configured by users to route traffic to specific destinations, such as other VPCs, VBRs, VPN Gateways, or NAT Gateways1. Custom routes can be modified or deleted as needed1. You can also associate VSwitches with different route tables to implement fine-grained routing control1.
Therefore, the statement that the routing entries of the route table can not be modified manually is not correct, as it only applies to system routes, not custom routes. The other statements are correct, as each VRouter may have multiple route tables, one default and several custom1; when a VPC is deleted, the corresponding route table is also deleted3; and the default route table cannot be deleted1.

- A. The DNS service provider used by the domain name (such as abc.com) can be companies other than Alibaba Cloud.
- B. If your domain name (such as abc.com) is transferred to Alibaba Cloud in advance, and managed by the same Alibaba Cloud account, you can perform one-step resolution modification.
- C. The DNS service provider used by the domain name (such as abc.com) must support intelligent resolution.
- D. The CNAME address allocated to the domain name (such as abc.com) will point to an IP address. This IP address resolving mechanism is intelligently managed by Alibaba Cloud CDN system.
正解：B
質問 # 41
By using ApsaraDB for RDS to implement read/write splitting, which of the following can be achieved?
(Number of correct answers 2)
- A. Read requests are distributed to multiple instances.
- B. Both read and write requests are distributed to multiple instance
- C. Read/write requests to the database are separated.
- 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 # 42
Alibaba Cloud Object Storage Service (OSS) is a cloud storage service that features massive capacity, outstanding security, low costs, and high reliability. In an OSS bucket, all elements are stored as________.
- A. Hashes
- B. Keys
- C. Objects
- D. Stubs
正解：C
解説：
Explanation
OSS does not use a hierarchical structure for objects, but instead uses a flat structure. All elements are stored as objects in buckets. To use OSS in the same manner in which local file systems are used, you can configure Cloud Storage Gateway (CSG).
https://www.alibabacloud.com/help/doc-detail/31817.htm
The statement C is correct, because in an OSS bucket, all elements are stored as objects. An object is the basic unit of OSS storage. Each object consists of a unique key, data, and metadata. The key is the name of the object, which is used to identify the object in a bucket. The data is the content of the object, which can be any type of file, such as text, image, video, or audio. The metadata is the information about the object, such as its size, type, creation time, and custom attributes. References: = Object Storage Service:Overview - Alibaba Cloud
質問 # 43
Which of the following privilege is required to manually install Alibaba Clod Security Center on the server?
- A. System administrator privilege
- B. Database Access privilege
- C. FTP service privilege
- D. Common user privilege
正解：A
解説：
Explanation
To manually install Alibaba Cloud Security Center on the server, you need to have the system administrator privilege. This is because the Security Center agent requires access to the system files and processes, and can perform security operations such as vulnerability scanning, intrusion detection, and threat blocking. A common user privilege or a database access privilege is not sufficient to install the Security Center agent. An FTP service privilege is irrelevant to the installation process.
