300-445 Question 58
Select 3An enterprise network administrator is tasked with setting a metric baseline for network performance monitoring. The administrator needs to ensure that the baseline accurately reflects normal network behavior over time. Which actions should the administrator take to achieve this goal?
- A
Collect performance data during peak and non-peak hours over an extended period.
- B
Use data from a single day to establish the baseline quickly.
- C
Exclude anomalous events, such as outages or attacks, from the baseline calculation.
- D
Rely on vendor-provided baseline values without tailoring them to the enterprise network environment.
- E
Analyze data trends to identify consistent patterns and variations before finalizing the baseline.
Show answer and explanation
Correct answers: A, C, E
Explanation
To set a reliable metric baseline, the administrator must gather data over an extended period, ensuring coverage of diverse network conditions (both peak and non-peak hours). Anomalous events should be excluded to avoid skewing the baseline with irregular activity. Additionally, analyzing trends ensures the baseline accurately reflects consistent network behavior. These steps ensure the baseline is robust and tailored to the enterprise's specific network environment, rather than relying on generic or insufficient data.
- A. Correct.
Collecting performance data during both peak and non-peak hours over an extended period ensures the baseline captures a wide range of normal network activity, providing a more accurate representation of typical performance.
- B. Incorrect.
Using data from a single day is insufficient to establish a comprehensive baseline as it may not account for variations in network activity over time.
- C. Correct.
Excluding anomalous events, such as outages or attacks, ensures the baseline reflects normal network behavior rather than one-time disruptions.
- D. Incorrect.
Relying solely on vendor-provided values is not recommended as they may not align with the specific characteristics of the enterprise network.
- E. Correct.
Analyzing data trends helps identify consistent patterns and variations, which is critical for refining and validating the baseline.
