An ICP license is a permit issued by the Chinese Ministry of Industry and Information Technology (MIIT) that allows websites to operate in China. An ICP license is required for any website that is hosted on a mainland China server, or that wants to use a China-based CDN service to accelerate its access in China. Therefore, you would need to apply an ICP license in the following cases:

Accelerate your Overseas Website in China: If you have a website that is hosted outside of China, but you want to use Alibaba Cloud's CDN service to improve its performance and user experience in China, you would need to apply an ICP license for your domain name. This is because Alibaba Cloud's CDN nodes are located in mainland China, and any website that uses them must comply with the Chinese regulations.

Launch your website in China: If you want to host your website on an Alibaba Cloud ECS instance or OSS bucket that is located in mainland China, you would need to apply an ICP license for your domain name. This is because any website that is hosted on a mainland China server must have an ICP license to be accessible and legal in China.

Launch your online shop in China: If you want to run an e-commerce website that sells goods or services to customers in China, you would need to apply an ICP license for your domain name. This is because any website that engages in commercial activities in China must have an ICP license to operate legally and securely in China.

Answer : A, B, C

Domain name binding is a feature that allows you to use your own domain name to access your OSS bucket, instead of using the default OSS domain name.Domain name binding has the following requirements and limitations12:

Your customized domain name will be audited by Alibaba Cloud. You need to submit a domain name binding request and wait for approval before you can use your own domain name to access your OSS bucket.

Your customized domain name need to be put on record in MIIT (Ministry of Industry and Information Technology). This is a mandatory requirement for all websites that are hosted in mainland China. You need to provide your domain name information and relevant documents to MIIT and obtain an ICP filing number before you can use your own domain name to access your OSS bucket.

Answer : A, C

OSS object types are the storage classes that define the performance and cost of storing objects in OSS.OSS supports four object types: Standard, Infrequent Access (IA), Archive, and Cold Archive1.Each object type has different characteristics and scenarios, such as availability, durability, minimum storage duration, and storage overhead2.

Object lifecycle management is a feature that allows you to manage objects efficiently and minimize costs throughout the lifecycle of the objects in your bucket. Lifecycle settings create a set of rules that help define the actions that an OSS bucket must perform on a group of objects.For example, you can configure lifecycle rules to automatically delete expired objects, or convert the storage class of objects to a lower-cost object type3.

You can configure lifecycle rules based on the object type of the objects in your bucket. You can specify the object type as a parameter for the lifecycle rule, and OSS will apply the rule to the objects that match the object type.For example, you can create a lifecycle rule to convert the object type of objects from Standard to IA after 30 days, and then to Archive after 180 days4.

Therefore, the correct answer is A. Infrequent access and C. Archive, as these are two of the object types that can be configured as parameters for object lifecycle management. B. Snapshot and D.Chunk are not valid object types in OSS.Reference:1:Overview of object types - Object Storage Service - Alibaba Cloud Documentation Center2:Object Storage Service (OSS) - Alibaba Cloud3:Manage Your OSS Storage Costs Using Lifecycle Policies - Alibaba Cloud4:Lifecycle rules based on the last modified time - Object Storage Service - Alibaba Cloud Documentation Center.

HTTPS: Hypertext Transfer Protocol Secure, an extension of HTTP that uses SSL/TLS encryption to provide secure communication between the client and the server.

TCP: Transmission Control Protocol, a reliable, connection-oriented transport-layer protocol that provides reliable data delivery and error recovery.

UDP: User Datagram Protocol, a connectionless transport-layer protocol that provides fast and efficient data transmission without guaranteeing reliability or order.

SLB does not support the following protocols:

MPLS: Multiprotocol Label Switching, a data-carrying technique that uses labels to forward packets across a network.

MQTT: Message Queuing Telemetry Transport, a lightweight publish/subscribe messaging protocol that is designed for constrained devices and low-bandwidth networks.

Session state data is the information that is associated with a specific user session, such as user preferences, shopping cart items, authentication tokens, etc. Session state data needs to be stored in a persistent and scalable way, so that it can be accessed by multiple web servers and survive server failures. Therefore, the suitable services for storing session state data are those that provide reliable, distributed, and high-performance data storage, such as RDS and Table Store.

RDS (Relational Database Service) is a fully managed online database service that supports various database engines, such as MySQL, SQL Server, PostgreSQL, MariaDB, and PPAS (PostgreSQL with Oracle compatibility)1. RDS provides high availability, backup and recovery, security, and monitoring features for your databases. RDS can store session state data in relational tables, and you can use SQL queries to access and manipulate the data.

Table Store is a fully managed NoSQL database service that provides consistent, scalable, and high-performance data storage for structured and semi-structured data2. Table Store organizes data in tables, rows, and columns, and supports primary key and attribute columns. Table Store can store session state data in flexible schemas, and you can use primary key queries or secondary index queries to access and manipulate the data.
