QUESTION: 36

A new VLAN vlan301 has been configured on a highly available LTM device in partition Application A. A new directly connected backend server has been placed on vlan301. However, there are connectivity issues pinging the default gateway. The VLAN self IPs configured on the LTM devices are 192.168.0.251 and 192.168.0.252 with floating IP 192.168.0.253. The LTM Specialist needs to perform a packet capture to assist with troubleshooting the connectivity.
Which command should the LTM Specialist execute on the LTM device command line interface to capture the attempted pings to the LTM device default gateway on VLAN vlan301?

tcpdump -ni /ApplicationA/vlan301 'host 192.168.0.253'
tcpdump -ni vlan301 'host 192.168.0.253'
tcpdump -ni /ApplicationA/vlan301 'host 192.168.0.251 or host 192.168.0.252'
tcpdump -ni vlan301 'host 192.168.0.251 or host 192.168.0.252'
