F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 48

An LTM Specialist must perform a packet capture on a virtual server with an applied standard FastL4 profile. The virtual server 10.0.0.1:443 resides on vlan301.
Which steps should the LTM Specialist take to capture the data payload successfully while ensuring no other virtual servers are affected?

Answer options

• A. The standard FastL4 profile should have PVA acceleration disabled. Then the packet capture tcpdump -ni vlan301 should be executed on the command line interface.
• B. The packet capture tcpdump -ni vlan301 should be executed on the command line interface. There is no need to change profiles or PVA acceleration.
• C. A new FastL4 profile should be created and applied to the virtual server with PVA acceleration disabled. Then the packet capture tcpdump -ni vlan301 should be executed on the command line interface.
• D. The LTM device is under light load. The traffic should be mirrored to a dedicated sniffing device. On the sniffing device, the packet capture tcpdump -ni

Correct answer: C

Explanation

The correct answer is C because creating a new FastL4 profile with PVA acceleration disabled ensures that the packet capture can be performed without impacting other virtual servers. Options A and B do not adequately address the need to disable PVA acceleration for capturing data from the specific virtual server, while D suggests an alternative method that may not be necessary given the requirements.
