Which type of connector is used for an Integrated Services Digital Network Basic Rate Interface (ISDN BRI)
connection?

A.
DB-60

B.
RJ-45

C.
AUI

D.
Console

Explanation:
An RJ-45 connector is used for an ISDN BRI connection. A BRI port is used in order to connect an
asynchronous BRI interface.
The DB-60 option is incorrect because the DB-60 connector is used to provide connectivity between
synchronous serial interfaces and Cisco routers. The serial ports are used to connect with the synchronous
serial interfaces. DB-60 serial ports are used for Wide Area Network (WAN) connections. High-speed lines (E1
or T1) can be configured using serial ports.
The AUI option is incorrect because the AUI connector is used with Ethernet ports.
The console option is incorrect because console port enables device management. It provides out-of-band
access to the router command line interface.Objective:
