Explanation:
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
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
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
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
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.

Explanation:
Here's how each protocol aligns with the correct TCP/IP model layer:
TCP (Transmission Control Protocol): This protocol belongs to the Transport layer, which is responsible for providing communication between applications on different hosts1.
IP (Internet Protocol): IP is part of the Internetwork layer, which is tasked with routing packets across network boundaries to their destination1.
FTP (File Transfer Protocol): FTP operates at the Application layer, which supports application and end-user processes. It is used for transferring files over the network1.
Ethernet: While not a protocol within the TCP/IP stack, Ethernet is associated with the Network Interface layer, which corresponds to the link layer of the TCP/IP model and is responsible for the physical transmission of data1.
The TCP/IP model layers are designed to work collaboratively to transmit data from one layer to another, with each layer having specific protocols that perform functions necessary for the data transmission process1.
TCP: TCP Model Layer: Transport
The Transport layer is responsible for end-to-end communication and error handling. TCP (Transmission Control Protocol) operates at this layer to provide reliable, ordered, and error-checked delivery of data.
IP: TCP Model Layer: Internetwork
The Internetwork layer, also known as the Internet layer, is responsible for logical addressing and routing. IP (Internet Protocol) operates at this layer to route packets across networks.
FTP: TCP Model Layer: Application
The Application layer provides network services to applications. FTP (File Transfer Protocol) operates at this layer to transfer files between computers over a network.
Ethernet: TCP Model Layer: Network
The Network layer, also known as the Link layer in the TCP/IP model, is responsible for physical addressing and access to the physical medium. Ethernet operates at this layer to provide the physical and data link functions.
Transport Layer: This layer is responsible for providing communication services directly to the application processes running on different hosts. TCP is a core protocol in this layer.
Internetwork Layer: This layer is responsible for logical addressing, routing, and packet forwarding. IP
is the primary protocol for this layer.
Application Layer: This layer interfaces directly with application processes and provides common network services. FTP is an example of a protocol operating in this layer.
Network Layer: In the TCP/IP model, this layer includes both the data link and physical layers of the OSI model. Ethernet is a protocol used in this layer to define network standards and communication protocols at the data link and physical levels.
