300-420 Question 266
Select 3An enterprise network is experiencing frequent outages and performance degradation. The organization wants to implement a proactive network management strategy to improve visibility and reduce downtime. Which network management techniques should be prioritized to achieve these goals?
- A
Implement SNMP-based monitoring to collect real-time device performance data.
- B
Deploy NetFlow or IPFIX for network traffic analysis and anomaly detection.
- C
Rely exclusively on manual troubleshooting during outages to identify root causes.
- D
Integrate Syslog servers to centralize and analyze device logs.
- E
Disable network management protocols to reduce configuration complexity.
Show answer and explanation
Correct answers: A, B, D
Explanation
Proactive network management relies on techniques that enhance visibility and provide actionable data to identify and resolve issues before they lead to outages. SNMP-based monitoring, NetFlow/IPFIX for traffic analytics, and Syslog for log centralization are all critical components of a comprehensive network management strategy. Manual troubleshooting and disabling management protocols do not align with proactive goals and may increase downtime.
- A. Correct.
SNMP (Simple Network Management Protocol) enables organizations to collect real-time data about device performance, such as CPU utilization, interface status, and error counters. This helps in proactive monitoring and troubleshooting.
- B. Correct.
NetFlow or IPFIX provides detailed insights into network traffic patterns, enabling the detection of anomalies and understanding of bandwidth usage, which contributes to proactive issue resolution.
- C. Incorrect.
Manual troubleshooting is reactive and time-consuming, making it unsuitable for a proactive management strategy.
- D. Correct.
Syslog servers allow centralized log collection and analysis from network devices. This helps in identifying issues and predicting failures based on log patterns.
- E. Incorrect.
Disabling network management protocols undermines visibility and control, conflicting with the goals of proactive monitoring and reduced downtime.
