An LTM Specialist configures two LTM devices in a high-availability pair with trusts established and device groups configured properly using network failover. After several months, the LTM Specialist notices that changes made to one LTM device do NOT cause the synchronization status to update to "changes pending," and this device does NOT synchronize with the device group.
Which two steps should the LTM Specialist take to identify the issue? (Choose two.)
An LTM device has been configured to log the reasons for generating TCP RST packets.
The following log entry occurs:
"01230140:3: RST sent from 192.168.1.100:80 to 192.168.1.124:39272, [0x112d82a:1721] {peer} TCP RST from remote system."
Which condition will trigger this log entry?
A device on the network is configured with the same IP address as the management address of the active LTM device, causing the management GUI to be inaccessible.
Which two methods should the LTM Specialist use to access the LTM device in order to change the management IP address? (Choose two.)

An LTM device is deployed in a one-armed topology. The virtual server, clients, and web servers are connected on the LTM device internal VLAN.
