1. The Border Control Point (BCP) replies to the originating end user
with an "alias", how will the end user apply the alias?
A. The originating end user will change just its source IP address to
match the alias IP address returned by the BCP.
B. The originating end user will change just its destination IP address
to match the alias IP address returned by the BCP.
C. The originating end user will change both its source IP address and
UDP port number to match the alias IP address and UDP port returned by
the BCP.
D. The originating end user will change both its destination IP address
and UDP port number to match the alias IP address and UDP port returned
by the BCP.
Answer: D

When using the System Management GUI (SMGUI), what process is used to
query a Border Control Point (BCP) alarm?
A. An alarm browser request is sent to the Database Manager (DBM), the
DBM sends a request to the BCP to deliver alarm information back to the
SMGUI.
B. An alarm browser request is sent to the BCP. The BCP sends a request
to the FPM, which collects the alarm information for the designated BCP
and returns the information to the BCP. The BCP re-formats the data and
sends it to the SMGUI.
C. An alarm browser request is sent to the SM. The SM sends a request to
the FPM, which collects the alarm information for all BCP and servers
administered by the SM and returns the information to the SM. The SM
re-formats the data and sends it to the SMGUI.
D. An alarm browser request is sent to the SM (System Manager), the SM
sends a request to the Fault and Performance Manager (FPM), which
collects the alarm information for a designated BCP and returns the
information to the SM. The SM re-formats the data and sends it to the
SMGUI.

At which level does an administrator perform the steps: Stop, UnDeploy,
Deploy and Start to upgrade a Border Control Point (BCP) series 7000 to a
new release?
A. Network Elements > Media Portals > RTP Portals > (BCP name)
> Instance
B. Network Elements > Media Portals > RTP Portals > (BCP name)
> NE Maintenance
C. Network Elements > Media Portals > Media Portal Cluster >
(cluster name) > Service Instances
D. Network Elements > Media Portals > Media Portal Cluster >
(cluster name) > Configuration Parameters
Answer: B

In the diagram below, which protocol is carried over the "Control Plane"
to the Border Control Point?
A. Real-time Transport Control Protocol (RTCP)
B. Transmission Control Protocol (TCP)
C. Media Portal Control Protocol (MPCP)
D. Real-time Transport Protocol (RTP)
Answer: C
5. Which technology does Border Control Point (BCP) use to redirect an
end user's Real-time Transport Protocol packets and shield network
components from external exposure?
A. Virtual Routing Redundancy Protocol (VRRP)
B. RSA (Rivest, Shamir and Adleman) IP frame encryption
C. Network Address and Port Translation (NAPT)
D. Ethernet Delay and Analysis Protocol (EDAP)
Answer: C
6. Click on the Exhibit button.
In a 3 + 1 fault tolerant cluster, which blade servers must be stopped
before upgrading to a new load?
A. any blade server in the cluster, since it will automatically
synchronize the new load from that blade server with all the other blade
servers in that cluster.
B. only the blade servers that are currently carrying active Real-time
Transport Protocol (RTP) / media streams.
C. all blade servers that are in the cluster, which includes the active
BCP 7200 blade servers (3), as well as the standby Border Control Point
(BCP) 7200 blade server.
D. only the active (3) blade servers in the cluster. The standby BCP
blade server (+ 1) must remain active so that, if a new call is
presented to the cluster during the upgrade procedure, the cluster can
process it.
Answer: C
7. How does the User Datagram Protocol (UDP) port contribute to the
security strategy of the Border Control Point (BCP)?
A. The UDP port number is provided by the end user's firewall and used
by the BCP to ensure the end user's validity.
B. Each IP frame is given the same UDP port number for every media
stream, thus giving the BCP the ability to "anchor" to any stream and
secure its path to the appropriate far end user.
C. For each Real-time Transport Protocol (RTP) media stream, a random
UDP port number is added to each IP packet, providing a unique
"signature" that the BCP uses to verify each frame for transport.
D. UDP port numbers given out by the BCP are used by the CS 2000 to
verify that the call is being made from and to registered users.

When a Border Control Point (BCP) is configured along with Session
Server Lines (SSL), the HP eXtremely Thin Server (HP-XTS) is used for
system management.
Which servers are provisioned on the HP_XTS?
A. the System Management Console (SMC)
B. the System Management Graphic User Interface (SMGUI)
C. the Fault and Performance Manager and the Database Manager
D. the System Manager, the Fault and Performance Manager, and the
Database Manager
Answer: D
