In the provided image of the Cisco PoE switch, the ports identified with number 6 are the standard RJ-45 Ethernet ports typically found on switches that provide both data connectivity and Power over Ethernet (PoE). PoE ports are designed to supply power to devices such as IP phones, wireless access points, and other PoE-enabled devices directly through the Ethernet cable.

Ports:

•2: Console port (for management and configuration)

•3 and 4: Specific function ports (often for management)

•6: RJ-45 Ethernet ports (capable of providing PoE)

•7: SFP ports (for fiber connections, typically do not provide PoE)

Thus, the correct answer is C. Ports identified with number 6.

Statement 1: Low bandwidth can increase network latency.

True: Low bandwidth can result in increased network latency because the network may become congested, leading to delays in data transmission.

Statement 2: High levels of network latency decrease network bandwidth.

False: High levels of network latency do not decrease the available network bandwidth, but they do affect the perceived performance and throughput of the network.

Statement 3: You can increase throughput by decreasing network latency.

True: Decreasing network latency can increase throughput because data can be transmitted more quickly and efficiently without delays.

Bandwidth vs. Latency: Bandwidth refers to the maximum rate at which data can be transferred over a network path. Latency is the time it takes for a data packet to travel from the source to the destination.

Low bandwidth can cause network congestion, which can increase latency as packets wait to be transmitted.

High latency does not reduce the actual bandwidth but can affect the overall performance and efficiency of data transmission.

Reducing latency can lead to higher throughput because the network can handle more data in a given period without delays.

Two home office computers are connected to a switch by Ethernet cables.

Network Type: LAN (Local Area Network)

Explanation: A LAN connects devices within a limited area such as a home, office, or building, using Ethernet cables or Wi-Fi.

Three government buildings in the same city connect to a cable company over coaxial cables.

Network Type: MAN (Metropolitan Area Network)

Explanation: A MAN connects networks across a city or campus, often using fiber optic or coaxial cables.

A cell phone connects to a Bluetooth headset.

Network Type: PAN (Personal Area Network)

Explanation: A PAN connects devices within a personal workspace, typically using wireless technologies like Bluetooth.

A financial institution connects its branches through a telecommunications service provider.

Network Type: WAN (Wide Area Network)

Explanation: A WAN connects multiple LANs over long distances, often using leased lines or satellite links provided by telecommunications companies.

LAN (Local Area Network): Used for connecting devices within a small geographical area such as a single building or home.

MAN (Metropolitan Area Network): Covers a larger geographical area than a LAN, typically a city or campus.

PAN (Personal Area Network): Connects devices within the range of an individual person, such as connecting a phone to a Bluetooth headset.

WAN (Wide Area Network): Spans large geographical areas, connecting multiple LANs across cities, countries, or continents.
