QUESTION 79
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?

HTTP

PPPoE

Restful

Web Service

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.

TRUE

FALSE

QUESTION 82
Alibaba Cloud OSS is a cloud storage service that features massive capacity, outstanding security, low costs, and high reliability. When talking about information security, the advantages of using OSS are
____________. (Choose two.)

Supports Anti-DDoS, automatic traffic cleaning, and “black holing” without any extra charges.

QUESTION 83
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?

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.

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.

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.

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.

QUESTION 84
The backend server pool of an Alibaba Cloud SLB contains multiple ECS instances, which may have different service capacities. To exploit the different service capacities of backend ECS instances, which of the following statements is correct?

Choose Weighted Round Robin mode to set higher weights to ECS instances with higher capacities The higher the weight of the backend ECS instance the higher chance that the instance will receive requests.

SLB cannot assign more requests to certain ECS instances.

Choose Round-Robin model and ECS instances with higher capacities will surely be assigned with more requests.

Choose Weighted Least-Connection mode, and ECS instances with higher capacities will surely be assigned with more requests.

QUESTION 85
RDS provides whitelist access policies. You can set permitted IP addresses and IP network segments to effectively prevent hackers from attacking the server by port scanning.

True

False

QUESTION 86
Object Storage Service (OSS) supports sub accounts, and you can allocate access permissions to different buckets for each sub account.

True

False

QUESTION 87
Alibaba Cloud Content Delivery Network (CDN) is a distributed network that is built and overlaid on the bearer network Moreover it is composed of edge node server clusters distributed across different regions. It replaces the traditional data transmission mode, which is centered on Web servers. When using Alibaba Cloud CDN, a user’s request wilt first reach the edge node, and then receive data from the origin site by means of back-to-source Moreover, the admin can obtain visitor’s real IP on the origin site. Which of the following descriptions relate to “obtaining visitors real IP” are correct? (Number of correct answers: 2)

“Visitor’s real IP” is saved in “X-Forwarded-For” header in HTTP protocol. It can be directly obtained in the user-defined LOG of Apache and Nginx.

“Visitor’s real IP” can only be obtained by modifying the application

You can one-step activate the “recording visitor’s real IP” function in Alibaba Cloud CDN console to directly view the visitor’s real IP in the access log.

In Windows, if IIS is used: after installing “F5XForwardedFor” extension module. ‘Visitor’s real IP” can then be seen in the log.

QUESTION 88
A large enterprise wants to migrate the entire business system to Alibaba Cloud to save the overall IT procurement and O&M costs From the security aspect, the company requires that
1. Must support secured remote O&M because the administrator often takes business trips.
2. Networks between subsystems should be isolated because subsystems are independently used by different departments Which of the followings should be used together to meet the company’s requirements? (Number of correct answers: 3)

Enable the VPN on the bastion host (or directly use the VPN image on Alibaba Cloud Marketplace).
The administrator uses VPN encrypted communication during O&M.

Build an independent ECS instance as the bastion host or remote logon and O&M, and authorize the bastion host to access ECS instances running other subsystems.

Use the security group function of the ECS instance, and respectively deploy ECS instances running different subsystems to independent security groups.

Create multiple ECS instances in the VPC to install subsystems of different departments- Allocate only Intranet IP addresses to all ECS instances, and deploy them in the same security groups.

Explanation
To meet the company’s security requirements, the following solutions should be used together:
A: Enable the VPN on the bastion host (or directly use the VPN image on Alibaba Cloud Marketplace).
The administrator uses VPN encrypted communication during O&M. This solution can support secure remote O&M, because VPN (Virtual Private Network) is a technology that creates a secure and encrypted connection over the Internet between the bastion host and the administrator’s device. VPN can protect the data transmitted between the bastion host and the administrator from being intercepted or tampered by malicious third parties1. Alibaba Cloud provides VPN Gateway service that allows users to create VPN connections between VPCs and on-premises data centers, or between VPCs in different regions2. Users can also use VPN images from Alibaba Cloud Marketplace, such as OpenVPN, to create VPN servers on ECS instances3.
B: Build an independent ECS instance as the bastion host or remote logon and O&M, and authorize the bastion host to access ECS instances running other subsystems. This solution can also support secure remote O&M, because a bastion host is a special-purpose ECS instance that acts as a proxy or a gateway for accessing other ECS instances in the VPC. A bastion host can enhance the security of the ECS instances by limiting the exposure of the ECS instances to the public network, and by implementing security policies and monitoring tools on the bastion host4. Alibaba Cloud provides Bastionhost service that allows users to centrally manage the access to cloud servers from external networks and provide secure connections to VPC resources5.
C: Use the security group function of the ECS instance, and respectively deploy ECS instances running different subsystems to independent security groups. This solution can isolate the networks between subsystems, because a security group is a virtual firewall that controls the inbound and outbound traffic of the ECS instances in the group. Users can configure security group rules to allow or deny access based on the network protocol, port, and source IP address. By deploying ECS instances running different subsystems to independent security groups, users can prevent unauthorized access or communication between the subsystems6.
The other solution is not suitable for the company’s scenario, for the following reason:
D: Create multiple ECS instances in the VPC to install subsystems of different departments- Allocate only Intranet IP addresses to all ECS instances, and deploy them in the same security groups. This solution cannot isolate the networks between subsystems, because ECS instances in the same security group can communicate with each other by default, regardless of whether they have intranet or internet IP addresses. Moreover, this solution may also prevent the ECS instances from accessing the internet or providing external services, which may affect the business operation of the company6.
