A company deploys a U1981 unified gateway, BMU, and CDRServer. The administrator wants to query CDRs within a time segment. Which of the following methods can the administrator use?

Question

Options

• ARun commands to query CDRs on the U1980.
• BQuery CDRs on the CDRServer management page of the CDRServer.
• CQuery CDRs on the eSight.
• DOpen the CDR file under D:\BILL\CurFile on the CDRServer.

• A

• B
  84% (36)
• C
  5% (2)
• D
  2% (1)

Explanation

Option B is correct because the CDRServer management page provides a dedicated administrative interface specifically designed for querying CDRs with time-segment filtering - it is the authoritative and purpose-built tool for this task in a deployment that includes a CDRServer.

Why the distractors are wrong:

• A references the U1980, not the U1981 that is actually deployed - using the wrong device's command interface would not apply to this environment.
• C (eSight) is Huawei's general network management platform; while it handles many functions, CDR time-segment queries are handled by the CDRServer, not eSight.
• D points to D:\BILL\CurFile, which holds actively-written current CDR files - these are raw, in-progress records not suited for structured time-segment queries and bypasses the proper administrative interface.

Memory tip: Match the tool to the task - since you deployed a CDRServer, you query CDRs on the CDRServer management page. If the question mentions a specific server role in the deployment, that server's own management interface is typically the correct answer for tasks specific to that role.
