301b Exam - Question 86

An LTM Specialist is troubleshooting an issue with a new virtual server. When connecting through the virtual server, clients receive the message "Unable to connect" in the browser, although connections directly to the pool member show the application is functioning correctly. The LTM device configuration is: ltm virtual /Common/vs_https { destination /Common/10.10.1.110:443 ip-protocol udp mask 255.255.255.255 pool /Common/pool_https profiles {

/Common/udp { }

}

translate-address enabled

translate-port enabled

vlans-disabled

}

ltm pool /Common/pool_https {

members {

/Common/172.16.20.1:443 {

address 172.16.20.1

}

}

}

What issue is the LTM Specialist experiencing?

Show Answer
Correct Answer: D

The issue is that the virtual server is configured for the incorrect protocol. The pool member is functioning correctly when accessed directly, indicating that the pool and its members are fine. The virtual server is set up to handle UDP traffic (`ip-protocol udp`), while port 443 typically handles HTTPS traffic over TCP. Therefore, the virtual server should be configured to use TCP, not UDP.
