A video company uses SLB to distribute user requests to 20 ECS instances with the same configuration to response these requests. As the Spring Festival approaches, service traffic would double during holidays (based on past experience). Thus, you use Auto Scaling to elastically adjust computing resources. Since the services is online for many years, you have historic records that can help predict the upcoming service traffic and choose the scaling mode freely. In this scenario, which of the following options are feasible and with minimum operation efforts? (Number of correct answers: 2)

• Cloud monitor and event-triggered task: Dynamically adds ECS instances during resource shortage and reduces ECS instances during idle hours by monitoring the CPU utilization rate and workload
  
• Scheduled task: Increases the number of ECS instances to 40 on the first day of the holidays and reduce the number to 20 after the holidays.
  
• Manual mode: Set the minimum number of instances to 40 on the first day of the holidays and change the number to 20 after the holidays.
  
• Healthy check mode: Ensures that all the current ECS instances in scaling groups are working correctly to meet user access requests.
  

Auto Scaling is a management service that can automatically adjust elastic computing resources based on your business needs and policies It supports adding an existing ECS instance into the scaling group but imposes certain requirements on instance region In this case, which of the following statements is true?

• The instance and the scaling group must be in the same region and zone.
  
• The instance and the scaling group must be in the same region but not necessarily the same zone.
  
• Each scaling group can span up to two regions. After adding the ECS instance, the number of regions of all the ECS instances in the scaling group must be no greater than two.
  
• The instance and the scaling group can be in different regions and zones.
  

The daily PV volume of a community website is as high as 20 million. The applications of the website are deployed on ECS instances while logs are stored on the data disks of a single ECS instance.Now, the website wants to extend the log retention period to 24 months and ensure that logs can be quickly downloaded when needed. The current data disks they have can only help retain three months of logs In this case, ________ is the ideal solution for solving the log retention issue.

• CDN
  
• Container Service
  
• OSS
  
• ApsaraDB for RDS
  

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

• True
  
• False
  

Alibaba Cloud ECS provides multiple instance types to meet the needs of different business scenarios. A medium-sized enterprise user wants to use two ECS instances, one to deploy a single Tomcat service and the other one to deploy Memcache. Which of the following configurations is most recommended?

• Tomcat: 4 cores. 8G, Memcache: 2 cores: 16G
  
• Tomcat: 4 cores 8G. Memcache: 2 cores 8G
  
• Tomcat: 4 cores, 4G, Memcache: 2 cores, 8G
  
• Tomcat: 4 cores: 4G, Memcache: 2 cores: 16G
  

Which of the following statements is most accurate about the Data Transmission Service (DTS) database migration function?

• Supports database schema replication between instances.
  
• Supports warning when source and destination has some unresolved conflict found.
  
• Supports all of the above functions.
  
• Supports migrating MySQL databases from external sources.
  

Alibaba Cloud Content Delivery Network (CDN) performs content acceleration with the support of intelligent DNS resolution The following function_________is NOT included in intelligent DNS resolution.

• A user request is directed to the server nearest to the customer based on location information of the pre-configured IP section.
  
• The intelligent DNS resolution can parse the same domain name into different IP addresses based on the IP of different visitors.
  
• The intelligent DNS resolution supports web page content caching. A user will receive data from the origin site at first-time access, and then will be reading data from cache in subsequent requests
  
• 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.
  

OSS supports multi-part uploading for large files, namely dividing a large file into multiple parts and uploading them in order. This function is suitable for scenarios such as uploading large files or uploading files with poor connectivity.After completing all the multi-part uploading tasks, if you forget to invoke the 'Complete Multipart Upload' interface, there will be fragment files left in OSS, occupying bucket storage space-To facilitate deleting those files, OSS provides the________function.

• OpenAPI batch deletion
  
• Online batch deletion
  
• Bucket clearing
  
• Fragment management
