You are asked to identify microburst traffic occurring in the network leading lo packet drops in your data center switches Which two tools would be used in this scenario? (Choose two.)

A.
port mirroring
Answers
A.
port mirroring
B.
Traceoptions
Answers
B.
Traceoptions
C.
port buffer monitoring
Answers
C.
port buffer monitoring
D.
syslog
Answers
D.
syslog
Suggested answer: A, C

Explanation:

Identifying Microburst Traffic:

Microbursts are short spikes in network traffic that can overwhelm buffers and cause packet drops. Detecting and analyzing microbursts is crucial for understanding where packet loss might be occurring in a data center network.

Port Buffer Monitoring:

Port Buffer Monitoring: This tool specifically tracks the usage of switch buffers, helping to identify when microbursts are causing buffers to overflow, leading to packet drops.

Port Mirroring:

Port Mirroring: This tool allows you to monitor real-time traffic on a specific port by copying the traffic to another port where it can be analyzed, often with a packet analyzer. While port mirroring doesn't directly detect microbursts, it helps capture traffic patterns that can indicate microbursts.

Conclusion:

Option C: Correct---Port buffer monitoring directly identifies buffer overflows caused by microbursts.

Option A: Correct---Port mirroring allows for the detailed capture and analysis of traffic patterns, which can reveal microburst behavior.

Options B (Traceoptions) and D (Syslog) are less effective in identifying microburst traffic. Traceoptions focus on control plane traffic debugging, and Syslog is more about logging system events than detecting high-frequency traffic spikes.
