Utility Entry Point for WAN Circuit Installation

A network administrator is adding a new WAN circuit from the ISP to a new building.

In which of the following locations would the network administrator find the utility entry point?

A.

DMZ

B.

Data tier

C.

IDF

D.

Demarc.

The utility entry point, also known as the demarcation point or demarc, is the point of connection between the service provider's network and the customer's network. It is typically located on the customer premises and is the responsibility of the customer to maintain and manage the equipment on their side of the demarc.

In the context of the question, the network administrator is adding a new WAN circuit from the ISP to a new building. This means that the demarcation point would be the location where the ISP's WAN circuit terminates on the customer's side of the network.

Option D, Demarc, is the correct answer as it refers to the point of termination for the new WAN circuit that the network administrator is adding from the ISP.

Option A, DMZ (Demilitarized Zone), refers to a security zone that separates a private network from the public internet. It is not relevant to the location of the demarcation point.

Option B, Data tier, refers to a logical architecture layer in which data is stored and processed. It is not relevant to the location of the demarcation point.

Option C, IDF (Intermediate Distribution Frame), is a location within a building where network equipment such as switches and routers are housed. While it may be a location where network connections are terminated, it is not specifically where the demarcation point is located.
