Which RAS message is used between two gatekeepers to resolve an alias address?

A.
GRQ

B.
ARQ

C.
IRQ

D.
LRQ

E.
RRQ

Explanation:
LRQ—These messages are exchanged between gatekeepers and are used for
inter-zone (remote zone) calls. For example, gatekeeper A receives an ARQ from a local zone
gateway requesting call admission for a remote zone device. Gatekeeper A then sends an LRQ
message to gatekeeper B. Gatekeeper B replies to the LRQ message with either a Location
Confirm (LCF) or Location Reject (LRJ) message, which depends on whether it is configured to
admit or reject the inter-zone call request and whether the requested resource is registered
