The tracert command output shows the path taken to reach the destination IP address, 192.168.1.10. The command output indicates:

•Hops 1 and 2 are successfully reached.

•Hop 3 times out, meaning the router at hop 3 did not respond to the tracert request. However, this does not necessarily indicate a problem with forwarding packets, as some routers may be configured to block or not respond to ICMP requests.

•Hops 4 and 5 are successfully reached, with hop 5 being the destination IP 192.168.1.10, indicating that the server is reachable.

Thus, the correct answer is C. The server with the address 192.168.1.10 is reachable over the network.

The tracert command output indicates that the server with the address 192.168.1.10 is reachable over the network. The asterisk (*) at hop 3 suggests that the probe sent to that hop did not return a response, which could be due to a variety of reasons such as a firewall blocking ICMP packets or the router at that hop being configured not to respond to ICMP requests. However, since the subsequent hops (4 and 5) are showing response times, it means that the packets are indeed getting through and the server is reachable12.

• The two interfaces are administratively shut down:
• The two interfaces have default IP addresses assigned:
• The two interfaces can communicate over Layer 2:

• Interface Status: The absence of the "shutdown" command means the interfaces are not administratively shut down.
• IP Address Assignment: There is no evidence in the output that IP addresses have been assigned to the interfaces, which would typically be shown as "ip address" entries.
• Layer 2 Communication: Switch interfaces in their default state operate at Layer 2, enabling them to forward Ethernet frames and participate in Layer 2 communication.

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 interfaceCable Type: = Straight-through UTP Cable

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

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

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

The choices are based on standard networking practices where:

• Straight-through UTP cablesare typically used to connect a switch to a router or a network interface card.
• Fiber optic cablesare ideal for long-distance, high-speed data transmission, such as connections through an underground conduit.
• Crossover UTP cablesare 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:
• Connects Router R2 Gi0/0/0 to Router R3 Gi0/0/0 via underground conduit:
• Connects Router R1 Gi0/0/0 to Router R2 Gi0/0/1:
• Connects Switch S3 to Server0 network interface card:

• 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.

The IEEE 802.11 standard contains the specifications for Wi-Fi networks. It is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication in various frequencies, including but not limited to 2.4 GHz, 5 GHz, and 6 GHz1. This standard is maintained by the Institute of Electrical and Electronics Engineers (IEEE) and is commonly referred to as Wi-Fi. The standard has evolved over time to include several amendments that improve speed, range, and reliability of wireless networks.
