Refer to the exhibit.

A virtual server is set up on an LTM device as follows: Virtual server address 78.24.213.79 Default Persistence ProfilE. source_addr, 600s. Pool NamE. Pool1 Pool Members: 10.72.250.52:80 and 10.72.250.60:80 (both on Internal Vlan) There are several current connections to the virtual server, and pool member 10.72.250.52:80 has been set to a "Disabled" state. A tcpdump on the Internal Vlan shows traffic going to 10.72.250.52:80. How soon after the persistence table query was run can existing connections be refreshed/renewed to ensure that no requests are sent to 10.72.250.52?
