QUESTION 21:
An electronics retailer was founded in 2001 and has been expanding rapidly. It has
21 existing locations throughout the Mid-Atlantic States. It plans to implement the
Cisco unity Messaging solution over the coming months. This Unity System will
integrate with Cisco call manager v3.3.
The company uses Cisco routers, switches, and firewalls. They installed a Cisco
CallManager cluster at the hosting center before the first opened. The corporate
network uses Microsoft Windows 2000 servers at the central hosting center with
Windows XP PC’s at the stores
There is a single forest and a single domain. All domain controllers and catalog
servers, and DNS servers reside at the hosting center. There are several database
servers for inventory management at the hosting center.
Each store has dual T1’s terminating at the hosting center via newly installed 3745
routers. The 3745 router were selected because of their scalability. The switched
infrastructure at each store is a single 48-or 24 port Cisco 3550 switch.
All store locations use the single CallManager cluster, two MCS-7835 servers,
located at the hosting center. Currently, most calls are to other stores or to the
hosting center. Locations are configured to allow three concurrent calls over the
WAN from each store.
Management is concerned about the effects of the network outrages on the stores’
ability to communicate with one another headquarters, and their Cisco Unity voice
mail stored at the hosting center.
What recommendation would you make to ensure access to voice mail and the
PSTN during a network outage?
A. use a redundant set of 3745 routers and BRI lines to provide service to Cisco Unity
during a network outage
B. configure a redundant set of 3550 switches and PRI lines to provide service to Cisco
Unity during a network outage
C. use the 3745 routers for SRST and PSTN connections; configure the 3745 to provide
DTMF access to the Unity server via the PSTN
D. configure the 3550 switches for SRST and PSTN connections; configure the 3550 to
provide DTMF access to the Unity server via the PSTN
Answer: C
