While reviewing monthly performance reports, a network administrator notices a trend of increased latency during peak business hours over the past three weeks. To determine the cause and appropriate solution, which of the following is the MOST effective step that the administrator should initially take?
Compare the current performance metrics to the established network performance baseline
Run a network protocol analyzer during peak hours to identify potential packet loss or retransmissions
Check for recent software updates that align with the start of the reported latencies
Review network device logs for any critical errors or warnings that correspond to the peak business hours
