Expert Solution & Answer
Chapter 2, Problem 1RQ
Program Description Answer
A technician of Internet Service Protocol (ISP) is taken to entrance facility to troubleshoot the problem related to Wide Area Network (WAN) connection.
Hence, the correct answer is option “D”.
Expert Solution & Answer
Explanation of Solution
Entrance facility:
The WAN that includes the group of LANs will be responsible for the problems which may arise in Internet Service Protocol. So the technician will be taken to entrance facility to troubleshoot the problem.
Explanation for incorrect options:
IDF:
- • It stands for Intermediate Distribution Frame.
- • It is a cable rack that manages and interacts with the Main Distribution Frame (MDF) and workstation devices.
Hence, the option “A” is wrong.
Work area:
Work area is related to the employees not to the ISP.
Hence, the option “B” is wrong.
CEO’s office:
CEO’s office is not related to ISP.
Hence, the option “C” is wrong.
