ISO Network Management Functions Quiz | Generated by AI
Question: According to ISO recommendations, the basic functions of network management should include fault management, configuration management, performance management, security management, and which of the following?
A. Customer management
B. Application management
C. Accounting management (or Billing management)
D. Operation management
Your answer: B
Correct answer: C
Answer:
The correct answer is C. 计费管理 (Accounting management / Billing management).
Explanation:
The ISO (International Organization for Standardization), specifically in the context of network management standards (OSI Network Management Framework, defined in ISO/IEC 7498-4 and related recommendations), defines five core functional areas of network management, commonly known as FCAPS:
- Fault Management（故障管理）
- Configuration Management（配置管理）
- Accounting Management（计费管理 / 帐务管理）
- Performance Management（性能管理）
- Security Management（安全管理）
Accounting Management (计费管理) is the official fifth functional area. It involves tracking resource usage, collecting billing data, assigning costs to users or departments, and supporting charging/billing processes.
Why the other options are incorrect:
- A. 客户管理 (Customer management) → Not part of the standard ISO FCAPS model.
- B. 应用管理 (Application management) → Application management is a higher-layer or separate domain (often part of application performance monitoring), not one of the five core ISO network management functions.
- D. 运营管理 (Operation management) → Too broad and not a specific functional area defined in the ISO model.
Therefore, the accurate and standard answer is C. 计费管理.
