Which two are events that can be used to trigger GTM iRule data processing? (Choose two.)

LB_FAILED is a valid GTM iRule event that triggers when the load balancing process cannot select a resource, allowing custom fallback logic to execute at that failure point.

DNS_REQUEST is the primary GTM iRule event, fired each time a DNS query arrives, and is used to inspect and manipulate DNS request processing such as selecting pools or modifying responses.

HTTP_REQUEST is an LTM iRule event associated with HTTP profile processing on virtual servers and is not part of the GTM iRule event model.

CLIENT_ACCEPTED is an LTM iRule event that fires when a client TCP connection is accepted by a virtual server and has no equivalent or applicability within GTM iRules.
