NEW QUESTION # 21
An LTM Specialist needs to force only FTP traffic, sourced from subnet 10.10.10.0/24 to virtual server 10.10.20.1 to the new FTP1 server. The following virtual servers are configured on the LTM device:
Traffic sourced from 10.10.10/24 must use the specific pool member for load balancing.
Which configuration change is needed to meet the requirements?
- A. Add FTP1 to the pool assigned to the MyVS2 virtual server, and remove all other pool member from the pool.
- B. Create a new virtual server for traffic sourced from 10.10.10.0/24 on port 80 that is destined to 10.10.20.1/32, and create a new pool has only the pool member FTP1 defined.
- C. Create a new virtual server for traffic sourced from 10.10.10.0/24 on traffic sourced from 10.10.10./24 on port 21 that is destined to 10.10.20.1/32, and create a new pool that has only the pool member FTP1 defined.
