F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 108

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 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
}
}
}
How should the LTM Specialist resolve this issue?

Answer options

• A. Remove an HTTP monitor from the pool.
• B. Add an HTTP profile to the virtual server.
• C. Enable the pool member on the correct VLAN.
• D. Select the correct protocol for the virtual server.

Correct answer: D

Explanation

The correct answer is D because the LTM configuration specifies UDP as the ip-protocol, which is not suitable for HTTP traffic that typically uses TCP. The other options do not address the fundamental issue of using the wrong protocol for the virtual server, hence they would not resolve the connectivity problem.
