During a routine check of network infrastructure health, a network administrator discovers that a critical layer 3 switch's resource consumption indicators have been showing elevated readings consistently during peak operational periods for several days. While all network services appear to be currently functional, these indications may suggest stress on the device's processing capabilities. What is the BEST immediate course of action for the administrator?
Continue to monitor without intervention as current network functionality does not appear to be compromised.
Modify the current configuration settings to reduce the resource consumption based on standard optimization practices.
Immediately initiate a replacement of the network device as the high resource utilization suggests impending hardware failure.
Conduct an in-depth inspection during a time with minimal network activity to understand the cause of the elevated resource consumption readings.
