1 / 3

A webhosting company needs to collect and analyze hundreds of gigabytes of log data each day, mostly in text format. Further, they want to be able to run full-text search over their log data set as well as generate alerts based on patterns in the collected log data. Which Alibaba Cloud tool fits this scenario best?

Log Service

MaxCompute

AnalyticDB

OSS

A large grade A tertiary hospital in China cooperates with some smart wearables manufacturers. They Score 2 want to use smart devices to collect the health data of patients offline and then use storage, analytic, and alarm applications provided by Alibaba Cloud to process the data. Alibaba Cloud also provides this hospital with data sources for other value-added applications. In this project, Alibaba Cloud applications must be compatible with devices of different manufacturers. Currently, more than 10 million smart devices are connected to the system, and this number is expected to increase to 100 million soon. The system must also be able to process millions of messages in parallel. The storage and real-time analysis of massive data are the biggest challenges. Assuming that you are a senior architect on this project, which of the following data storage solutions do you think best meets the requirements?

Upload data of the smart devices to the business system cluster through a Wi-Fi or 4G network, convert the data into structured data, use DRDS and RDS databases to store the data, use DRDS as distributed database middleware, and perform database and table sharding based on the business characteristics for convenient and fast access to massive data. DRDS allows users to use a distributed database like a standalone database to smoothly execute SQL queries.

Use loT Hub to collect data from the smart devices, upload all data from the smart devices to OSS for storage (in CSV format), and use OSS as the data warehouse for MaxCompute, which can directly analyze the data offline.

Upload data from the smart devices to the business system cluster through a Wi-Fi or 4G network, convert the data into semi-structured data, and then store the semi-structured data in AnalyticB (ADS).

Use loT Hub to collect data from the smart devices, use a rules engine to clean the data, and send the clean data to different Alibaba Cloud services. For example, store the real-time health metrics in TableStore (as Stream SQL data) for data retrieval and in AnalyticB for real-time OLAP analysis, and then store the OLAP analysis results in an ApsaraDB for RDS database.

An enterprise is building a business system on Alibaba Cloud and requires the system to have availability, disaster recovery capability, and business continuity features. Which of the following policies is not directly helpful in achieving the enterprise's goals?

Back up data every 10 minutes and save copied data to another region.

Assign an elastic IP address (EIP) to an Elastic Compute Service (ECS) application server, and use Alibaba Cloud Domain Name Service (DNS) to resolve the domain name to the EIP.

Create a Server Load Balancer (SLB) instance in two regions respectively and configure automatic failover between the two SLB instances.

Create an image of an ECS instance and transmit the image to another region for storage through an image copy.
