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.
