A user needs to collect logs from the elastic cloud server ECS through the cloud log service TS. Which of the following description of the LTS service is wrong?

Question

Options

• AYou can set the log storage time by creating a log stream
• BCAgent needs to be installed for the ECS host
• CLog groups can be created in the log stream to facilitate further classification and management of
• DThe log data beyond the storage time will be automatically deleted, and the log data that needs to

• A
  4% (1)
• B
  8% (2)
• C
  72% (18)
• D
  16% (4)

Explanation

Option C is wrong because it reverses the actual hierarchy of LTS: log streams are created inside log groups, not the other way around. In Huawei Cloud LTS, a log group is the top-level container, and log streams are subdivisions within a log group used for finer classification. Option A is correct because log stream settings do include configurable retention/storage duration. Option B is correct because the ICAgent (referred to here as CAgent) must be installed on the ECS host to enable log collection. Option D is correct because LTS automatically purges log data once it exceeds the configured retention period, which is standard behavior across cloud logging services.

Memory tip: Picture a filing cabinet where the log group is the drawer and log streams are the folders inside it. Folders go inside drawers, never the reverse, so a log group cannot be created inside a log stream.
