Which two can be a part of a pool's definition. (Choose two.)

A BIG-IP Administrator creates an HTTP Virtual Server using an iApp template. After the Virtual Server is created, the user requests to change the destination IP addresses. The BIG-IP Administrator tries to change the destination IP address from 10.1.1.1 to 10.2.1.1 in Virtual Server settings, but receives the following error:
The application service must be updated using an application management interface What is causing this error?

An LTM device has a virtual server mapped to www5f.com with a pool assigned. The objects are defined as follows:
Virtual server. Destination 192.168.245.100.443 netmask 255.255.255.0
Persistence: Source address persistence netmask 255.0.0.0
SNAT:AutoMap
Profiles: HnP/TCP
How should the BIG-IP Administrator modify the persistence profile so that each unique IP address creates a persistence record?

What is the purpose of MAC masquerading?
