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.
OSS provides the fragment management function to help you delete the fragment files left in OSS after you forget to invoke the ''Complete Multipart Upload'' interface. Fragment management allows you to list, delete, or restore the fragment files in a bucket. You can use the OSS console, OSS SDKs, or OSS APIs to perform fragment management operations. OpenAPI batch deletion, online batch deletion, and bucket clearing are not the functions provided by OSS to delete the fragment files.
Which of the following privilege is required to manually install Alibaba Clod Security Center on the server?
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.
Which of the following statements about file uploading to OSS is NOT correct?
Not all upload methods in Alibaba Cloud OSS support resuming from a breakpoint. Only specific methods, such as multipart upload, support this feature. Small files can be uploaded using a single PUT request, while APPEND is useful for continuously updated log files. For large files, multipart uploading is recommended to handle potential interruptions.
A challenging thing in the gaming industry is the unpredictable and fluctuating business traffic. For example, 1 ECS instance is enough to meet all business demands today; however, we may need 10 ECS instances tomorrow.
In this situation, it is difficult to predict the number of ECS instances required. If we use too few ECS instances, we may not be able to cope with business peaks; whereas if we use too many ECS instances, we may introduce unnecessary costs.
On Alibaba Cloud, _______________ is the best product portfolio to cope with the gaming scenario described above.
In this scenario, a combination of Server Load Balancer (SLB), ECS, ApsaraDB for RDS, and Auto Scaling is ideal. SLB distributes incoming traffic across multiple ECS instances, ensuring high availability and reliability. Auto Scaling automatically adjusts the number of ECS instances based on demand, managing costs efficiently by scaling out during peak times and scaling in when demand decreases. ApsaraDB for RDS provides a managed database service that handles increasing database demands without requiring complex manual scaling. This portfolio is optimal for fluctuating gaming traffic as it ensures load balancing, scalability, and cost control.
Which of the following methods can be used to connect with the database in RDS for MySQL? (Choose three.)
RDS for MySQL supports connections through tools that are compatible with MySQL, such as MySQL-Front, Navicat MySQL, and command-line MySQL commands. SQL Server Management Studio (SSMS) is designed for Microsoft SQL Server and is not compatible with MySQL, so option D is incorrect.
