DNS queries from two internal DNS servers are load-balanced to external DNS servers through a Virtual Server on a BIG-IP device. The DNS queries originate from 192.168.101.100 and 192.168.101.200 and are directed to 192.168.21.50.

All DNS queries intended for the external DNS servers fail. Which Virtual Server property should the BIG-IP Administrator change to fix this issue?

Explanation

The virtual server must use UDP because conventional DNS queries are sent on UDP port 53. A TCP virtual server does not match those UDP flows. The configured /23 source network already includes both 192.168.101.100 and 192.168.101.200.
