Question
A virtual server is defined using a source address based persistence profile. The last five connections were A, B, C, A, C . Given the conditions shown in the graphic, if a client with IP address 205.12.45.52 opens a connection to the virtual server, which member will be used for the connection?

Why each option
With a source address persistence profile, subsequent connections from the same client IP are directed to the same pool member based on an existing persistence record.
This member would only be used if the persistence entry for 205.12.45.52 specifically mapped to 10.10.20.1:80.
When a source address persistence profile is active, the BIG-IP uses the client's source IP address to look up an existing entry in the persistence table, directing new connections from that client to the previously established pool member (10.10.20.2:80, as indicated by the correct answer).
This member would only be used if the persistence entry for 205.12.45.52 specifically mapped to 10.10.20.3:80.
This member would only be used if the persistence entry for 205.12.45.52 specifically mapped to 10.10.20.4:80.
This member would only be used if the persistence entry for 205.12.45.52 specifically mapped to 10.10.20.5:80.
