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.

Understanding Different Network Types: Network Types Guide

Based on the image description provided, here are the cable types matched with the appropriate connection descriptions:

Connects Switch S1 to Router R1 Gi0/0/1 interface Cable Type: = Straight-through UTP Cable

Connects Router R2 Gi0/0/0 to Router R3 Gi0/0/0 via underground conduit Cable Type: = Fiber Optic Cable

Connects Router R1 Gi0/0/0 to Router R2 Gi0/0/1 Cable Type: = Crossover UTP Cable

Connects Switch S3 to Server0 network interface card Cable Type: = Straight-through UTP Cable

The choices are based on standard networking practices where:

Straight-through UTP cables are typically used to connect a switch to a router or a network interface card.

Fiber optic cables are ideal for long-distance, high-speed data transmission, such as connections through an underground conduit.

Crossover UTP cables are used to connect similar devices, such as router-to-router connections.

These matches are consistent with the color-coded cables in the image: green for switch connections, yellow for router-to-router connections within the same rack, and blue for inter-rack connections. The use of these cables follows the Ethernet cabling standards.

Connects Switch S1 to Router R1 Gi0/0/1 interface:

Cable Type: Straight-through UTP Cable

Explanation: A straight-through UTP cable is typically used to connect different types of devices, such as a switch to a router.

Connects Router R2 Gi0/0/0 to Router R3 Gi0/0/0 via underground conduit:

Cable Type: Fiber Optic Cable

Explanation: Fiber optic cables are used for long-distance connections, such as those through an underground conduit between buildings.

Connects Router R1 Gi0/0/0 to Router R2 Gi0/0/1:

Cable Type: Crossover UTP Cable

Explanation: A crossover UTP cable is typically used to connect similar devices directly, such as router to router connections.

Connects Switch S3 to Server0 network interface card:

Cable Type: Straight-through UTP Cable

Explanation: A straight-through UTP cable is typically used to connect a switch to an end device, such as a server.

Straight-through UTP Cable: Used to connect different devices (e.g., switch to router, switch to server).

Crossover UTP Cable: Used to connect similar devices directly (e.g., router to router, switch to switch).

Fiber Optic Cable: Used for long-distance and high-speed connections, often between buildings or data centers.

•Statement B: "The same default gateway IPv4 address is configured on each host on the local network." This is true because all hosts on the same local network (subnet) use the same default gateway IP address to send packets destined for other networks.

•Statement D: "The default gateway is the IPv4 address of the router interface connected to the same local network as the host." This is true because the default gateway is the IP address of the router's interface that is directly connected to the local network.

•Statement A: "The IPv4 address of the default gateway must be the first host address in the subnet." This is not necessarily true. The default gateway can be any address within the subnet range.

•Statement C: "The default gateway is the Loopback0 interface IPv4 address of the router connected to the same local network as the host." This is not true; the default gateway is the IP address of the router's physical or logical interface connected to the local network.

•Statement E: "Hosts learn the default gateway IPv4 address through router advertisement messages." This is generally true for IPv6 with Router Advertisement (RA) messages, but not typically how IPv4 hosts learn the default gateway address.

Firewall: A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It permits or denies traffic based on IP addresses, port numbers, or applications.

Access Point: This is a device that allows wireless devices to connect to a wired network using Wi-Fi. It does not perform traffic filtering based on IP, port, or application.

VPN Gateway: This device allows for secure connections between networks over the internet, but it is not primarily used for traffic filtering based on IP, port, or application.

Intrusion Detection System (IDS): This device monitors network traffic for suspicious activity and policy violations, but it does not actively permit or deny traffic.

To list the IPv4 addresses associated with the host name www.companypro.net, you should use the following command:

nslookup www.companypro.net

This command will query the DNS servers to find the IP address associated with the hostname provided. If you want to ensure that it returns the IPv4 address, you can specify the -type=A option, which stands for Address records that hold IPv4 addresses1. However, the nslookup command by default should return the IPv4 address if available.

To list the IPv4 addresses associated with the host name www.companypro.net , you should use the nslookup command.

Command: nslookup

Target: www.companypro.net

So, the completed command is:

nslookup www.companypro.net

nslookup: This command is used to query the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record.

www.companypro.net : This is the domain name you want to query to obtain its associated IP addresses.
