When a Cisco IOS gatekeeper receives an LRQ, what is the first step it will take in an attempt to
resolve the destination address?

A.
Check to see if the LRQ reject-unknown-prefix flag is set.

B.
Check to see if the destination address matches the technology prefix.

C.
Check to see if the destination address matches the hop-off technology prefix.

D.
Check to see if the destination address matches the remote zone prefix.

E.
Check to see if the LRQ forward-queries flag is set.

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.
