Which three must be done so that Generic Host Servers can be monitored using SNMP? (Choose three.)
The correct answer is C. The GTM System must be configured for the appropriate MIB . D. The Generic Host Server must be added to the GTM Configuration. E. The Generic Host Server must be enabled to answer SNMP queries.. Monitoring Generic Host Servers via SNMP in F5 GTM requires the server to exist in the GTM configuration, be capable of responding to SNMP queries, and the GTM must have the correct MIB loaded.

Why each option
Monitoring Generic Host Servers via SNMP in F5 GTM requires the server to exist in the GTM configuration, be capable of responding to SNMP queries, and the GTM must have the correct MIB loaded.
Adding an SNMP monitor to all BIG-IP Systems is not required because SNMP monitoring of Generic Host Servers is handled directly by the GTM, not delegated to LTM instances.
The big3d agent is used on BIG-IP LTM systems to communicate metrics back to GTM - Generic Host Servers are non-F5 devices and cannot run the big3d agent.
The GTM must be configured with the appropriate SNMP MIB so it can interpret the OIDs returned by the Generic Host Server during polling. Without the correct MIB, the GTM cannot parse the SNMP response data meaningfully.
The Generic Host Server must be added to the GTM configuration as a server object so the GTM knows it exists and can target it for health monitoring.
The Generic Host Server itself must have an SNMP agent running and configured to respond to queries from the GTM's IP, otherwise the monitor checks will time out or be refused.
