Correct Answer: A,E,F 🗳️
Cisco was approached by the Minister of the Education Department, to start an experiment in one of the public school districts since the government passed a Bill that all schools are to comply with the Safe Schools Initiative.
The situation at the schools in this district is as follows:
The district has approximately 3000 students dispersed in the following manner:
- one high school, one junior high school and three grade schools.
All the phone calls to these schools are switched by a local telephone company's centrex switch after which it is routed to the appropriate school.
The schools are all fitted with fractional T1 Frame Relay and Cisco routers for networking purposes. The users are on a switched 10/1/100 network utilizing Cisco switched and Category 5 cable. The high school has the Internet access through an Internet Service Provider which resides 35 miles away via a T1 Frame Relay. This internet connection is shared with the other schools in the district.
Due to the Safe Schools Initiative, phones need to be put in each classroom. Though the costs are astronomical and there are no facilities, the schools would also want to install video in each school for video conferencing purposes and it will be a definite aid in distance learning for the high school. ISDN PRI LINKS will be used to connect the video partners.
In addition to the above, there is also the student
information; that is stored on the
local servers and shared between the schools as learners graduate from elementary to junior high to high school as well as transfers in and out of the district; that has to be protected.
