Q1. Which protocol provides mechanisms ensuring data is reliably delivered?
Answer: Transmission Control Protocol (TCP)
Explanation: TCP provides reliable data delivery by establishing a connection, sequencing packets, and ensuring they are delivered without errors.
Q2. Which of the following is the first layer of the TCP/IP Five-layer network model?
Answer: Physical
Explanation: The Physical layer is the first layer in the network model and is responsible for the actual transmission of data over physical media.
Q3. Which layer of the network model includes specifications for cables and connectors and how signals are sent over these connections?
Answer: Physical
Explanation: The Physical layer defines hardware standards like cables, connectors, and signaling methods used for data transmission.
Q4. True or false: Fiber cables use pulses of light to represent the ones and zeros of data.
Answer: True
Explanation: Fiber-optic cables transmit data using light signals, where pulses of light represent binary data.
Q5. You have installed a device at the physical layer. All of the systems you connect to this device will talk to each other at the same time. What have you installed?
Answer: Hub
Explanation: A hub operates at the Physical layer and broadcasts all incoming signals to every connected device, leading to collisions when multiple devices communicate simultaneously.
Q6. Which of the following is a device that knows how to forward traffic between independent networks?
Answer: Router
Explanation: Routers are networking devices designed to route traffic between different networks by examining IP addresses.
Q7. What device provides emails to devices like laptops and desktop computers?
Answer: Server
Explanation: Servers host applications, including email servers, which deliver and store emails for clients like laptops and desktops.
Q8. A Local Area Network (LAN) uses Category 6 cabling. An issue with a connection results in a network link degradation and only one device can communicate at a time, but information can still go in either direction. What is the connection operating at?
Answer: Half Duplex
Explanation: In Half Duplex mode, data flows in both directions, but only one device can send data at a time.
Q9. Fill in the blank: There will almost always be some troubleshooting data available through _____.
Answer: Port lights
Explanation: Port lights (or action LEDs) on network devices provide basic diagnostic information, such as whether a port is active or connected.
Q10. Fill in the blank: The most common data link layer protocol for wired connections is _____.
Answer: Ethernet
Explanation: Ethernet is the dominant protocol at the Data Link layer for wired LANs, defining how devices communicate over a physical medium.
