F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 88

An application owner claims an LTM device is delaying delivery of an HTTP application. The LTM device has two VLANs, an internal and an external. The application servers reside on the internal VLAN. The virtual server and clients reside on the external VLAN.
With appropriate filters applied, which solution is most efficient for obtaining packet captures in order to investigate the claim of delayed delivery?

Answer options

• A. one capture on interface 0.0
• B. one capture on the internal interface
• C. one capture on the external interface
• D. one capture on the management interface

Correct answer: A

Explanation

Capturing packets on interface 0.0 is the most efficient approach because it allows for the observation of traffic flowing between both VLANs, capturing interactions between the clients and the application servers. The internal and external interfaces would limit the view to one side of the communication, while the management interface does not handle application traffic, making them less effective for this investigation.
