Best Network Device for IP Phones and Computers | Technology for Maximum Throughput

Connectivity Options for IP Phones and Computers

Prev Question Next Question


A company is installing IP phones. The phones and office computers connect to the same device. To ensure maximum throughput for the phone data, the company needs to make sure that the phone traffic is on a different network from that of the office computer data traffic. What is the best network device to which to directly connect the phones and computers, and what technology should be implemented on this device? (Choose two.)

The best network device to connect the IP phones and computers is a switch, and the technology that should be implemented on this device is VLAN.

VLANs (Virtual Local Area Networks) are a way of logically dividing a single physical network into multiple virtual networks. This allows the phones and computers to be placed on different VLANs and segregates their traffic. Each VLAN operates as if it were on a separate physical network, and devices on different VLANs cannot communicate with each other without routing.

A switch is the best device to use because it allows for the creation of multiple VLANs and can assign ports to specific VLANs. This means that each port on the switch can be assigned to either the VLAN for phone traffic or the VLAN for computer traffic. This segregation of traffic ensures maximum throughput for the phone data.

Hubs, on the other hand, are not recommended because they broadcast all traffic out to every device on the network, causing congestion and potentially introducing security risks.

Routers can be used, but they are not as efficient as switches in handling VLANs. Routers are used to connect different networks, and although they can implement VLANs, they require the use of subinterfaces, which can be complex and time-consuming to configure.

Spanning Tree Protocol (STP) is used to prevent loops in the network and is not directly related to segregating phone and computer traffic.

In summary, a switch with VLANs implemented is the best network device to connect IP phones and computers while segregating their traffic, ensuring maximum throughput for the phone data.
