Question
Company XYZ wants to use the FCAPS ISO standard for network management design. The focus of the design should be to minimize network outages by employing a set of procedures and activities to detect and isolate network issues and the appropriate corrective actions to overcome current issues and prevent them from occurring again. Which layer accomplishes this design requirement?
A. fault management
B. accounting management
C. security management
D. performance management
Answer
A. fault management
Explanation
The correct answer to the question is A. fault management.
The FCAPS model is an ISO standard for network management that stands for Fault, Configuration, Accounting, Performance, and Security. Each component of the FCAPS model addresses a specific aspect of network management.
In this scenario, Company XYZ wants to minimize network outages by employing procedures and activities to detect and isolate network issues and take appropriate corrective actions. This objective aligns with the “fault management” component of the FCAPS model.
Fault management focuses on detecting, isolating, and resolving network faults or issues. It involves monitoring the network infrastructure and devices to identify any abnormal conditions, failures, errors, or malfunctions. The goal is to quickly detect network issues, minimize downtime, and restore normal network operations.
The fault management layer employs various mechanisms and techniques to achieve its objectives, including:
- Network monitoring: Active and passive monitoring tools are used to continuously monitor network devices, links, and performance metrics. This includes monitoring network availability, device health, link status, and performance indicators.
- Fault detection and notification: When network issues occur, fault management systems generate alerts, notifications, or alarms to inform network administrators or operations teams. These alerts provide information about the nature of the fault, affected devices or services, and their impact on network operations.
- Fault isolation and troubleshooting: Once a fault is detected, fault management processes help identify the root cause of the issue. This involves analyzing network logs, diagnostic data, and performing troubleshooting procedures to isolate the fault to a specific device, component, or configuration.
- Corrective actions and problem resolution: After fault isolation, appropriate corrective actions are taken to resolve the issue and restore normal network operations. This may involve device reconfiguration, software updates, hardware replacement, or other remediation measures.
The primary objective of fault management is to minimize network outages, ensure network reliability, and maintain service availability. By promptly detecting and resolving network faults, this layer plays a crucial role in reducing downtime and improving overall network performance.
In summary, the fault management layer of the FCAPS model addresses the design requirement of minimizing network outages by employing procedures and activities to detect, isolate, and resolve network issues. It focuses on quickly identifying faults, taking appropriate corrective actions, and preventing future occurrences.
