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.
