Exam Description
The Gateway Gatekeeper exam assesses the knowledge of the Systems Engineer on the implementation of Cisco gateways and gatekeepers to integrate a VoIP network to both PSTN and TDM equipment. This includes implementing dial plans and advanced gateway features such as SRST and DSP resources. The exam also covers implementing gatekeepers and directory gatekeepers to provide hierarchical dial plan resolution and call admission control.

QUESTION 21:
Exhibit
voice translation-rule 1
rule 1/^\(617\)\(…\)\(…\)//3\2\3/
What will be the result if the number 617-269-1212 is put through the Cisco IOS software voice
translation rule displayed in the exhibit?
A. 36172691212
B. 1212269
C. 32691212
D. 6171212
Answer: C
Explanation: In general form , rule precedence /match pattern/ /replacement pattern/ In the question,
1/^\(617\)\(…\)\(…\)/ /3\2\3/ is the given translation rule. Hence, Rule number : 1 match pattern :
^\(617\)\(…\)\(…\) replacement pattern: 3\2\3
The match pattern says that the rule will apply to any pattern begins with 617. The replacement pattern says add
digit 3 and insert set 2 and insert set 3 digits in the match pattern. In the question, the number given is
617-269-1212 . set 1 : 617 set 2 : 269 set 3 : 1212
Based on the replacement rule , the answer is C : 32691212.
QUESTION 22:
Which is a use of GKTMP?
A. updating information in directory gatekeepers
B. providing SIP to H.323 protocol translation for RAI in SIP networks
C. querying third-party applications to implement specific policy controls
D. transmitting state information to alternate gatekeepers for load balancing
Answer: C
Explanation: Gatekeeper Transaction Message Protocol (GKTMP) can extend the
call control intelligence of a gatekeeper by providing an interface to a route
application server where advanced routing decisions can be made. It converts
incoming RAS messages to text messages and sends them to an off-board server.
The server can override default gatekeeper behavior.
GKTMP is an independent platform and can run on Solaris, Linux, Microsoft Windows
NT. It allows third parties to develop sophisticated applications to control RAS
communication. An example of the use of GKTMP is where a service provider wants to
control the call routing behavior of certain calls during a certain time of the day. The
gatekeeper in this case will offload the routing instructions to the route application server
and process the request from the server for altered call routing behavior.

QUESTION 23:
Drag and drag the commands to the proper location. Each command may be used either in the interface
or the gatekeeper configurations, or in both. All boxes may not be filled and commands may be used
more than once. The IP address command has been entered for you.
Answer:
Explanation: The primary gatekeeper will contain the following configuration on
the ethernet interface.
interface ethernet 0
ip address 10.1.1.1 255.255.255.0
stanby 1 ip 10.1.1.10
standby 1 preempt
standby 1 timers 5 15
standby 1 priority 110
no shutdown
Though not shown in the list of commands to choose, the timers are very important, if the
values are not sent to the same number in both routers, HSRP will not function properly.
This router will be the priority gatekeeper for HSRP because of the standby 1 priority
110 statement. The default value is 100 in a range from 1 to 255. The standby router
(alternate) will not need to have the standby priority statement. The standby router

(alternate) assumes the default priority of 100, meaning the primary gatekeeper is the one
set with the higher priority at 110.
The gatekeeper mode will contain the following configuration:
gatekeeper
zone local GK- Certkiller A Certkiller .com 10.1.1.10
zone remote GK- Certkiller C Certkiller .com 10.1.20.10 1719
zone prefix GK- Certkiller A 408
zone prefix GK- Certkiller C 425
no shutdown
