Q
Which three areas have advanced due to significant contributions from Broadband Network and Services?
AA. Atm, sonet/sdh, and broadband access technology
BB. Mpls, switching technology, and broadband technology
CC. Frame relay, isdn and narrowband access technology
DD. VPN, firewall, and WAN technology
Correct Answer:
A. A. Atm, sonet/sdh, and broadband access technology
Explanation:
Some network services require larger bandwidths that could not be achieved using Frame Relay. This has led to the implementation of broadband ISDN or also known as broadband network. Broadband network and service have contributed significantly in three areas. They are ATM (Asynchronous Transfer Mode), SONET (Synchronous Optical Network)/SDH (Synchronous Digital Hierarchy), and broadband access technology.
