Free CIW Network Technology Associate Questions and Answers — Questions and Answers
Question 1: The information 2E22:4F00:000E:00D0:A267:97FF:FE6B:FE34 is referenced by which of the following?
- AnIPv4address
- An IP diagnostic loopback address
- A MAC address
- An IPv6 address (Correct answer)
Correct answer: An IPv6 address
The given string 2E22:4F00:000E:00D0:A267:97FF:FE6B:FE34 is an example of an IPv6 address. IPv6 addresses are 128-bit hexadecimal numbers, typically written as eight groups of four hexadecimal digits separated by colons. In contrast, IPv4 addresses consist of four decimal numbers separated by dots, and MAC addresses are usually 12 hexadecimal digits separated by hyphens or colons.
Question 2: A BYOD policy contains __________.
- Insurance on devices
- Scope of control (Correct answer)
- Device replacement or upgrade
- Maintenance provision
Correct answer: Scope of control
A BYOD (Bring Your Own Device) policy primarily defines the extent to which an organization can manage, monitor, and secure personal devices used for work. It outlines what data can be accessed, what security measures must be in place, and the organization's responsibilities versus the employee's. This 'scope of control' is crucial for balancing security needs with employee privacy and device ownership.
Question 3: Which of the following steps should be taken first to troubleshoot a network connection issue while using a cable modem?
- Ping the default gateway
- Ping local devices using their IP addresses (Correct answer)
- Ping the proxy server
- Ping local devices using their DNS names
Correct answer: Ping local devices using their IP addresses
When troubleshooting a network connection, the first step is to isolate the problem. By pinging local devices using their IP addresses, you can determine if the network interface card (NIC) and the local network stack are functioning correctly. This helps confirm basic connectivity within your immediate network segment before attempting to reach external resources or resolve DNS.
Question 4: What causes a computer to have several open ports, reboot without notice, suddenly turn off the monitor, play sounds out of the blue, and have the hard drive light flash continuously?
- The computer is experiencing a denial-of-service attack.
- The computer has been infected with an illicit server. (Correct answer)
- The computer has been infected by a worm.
- The computer has been infected with a polymorphic virus.
Correct answer: The computer has been infected with an illicit server.
The symptoms described, such as open ports, reboots, monitor turning off, sounds, and continuous hard drive activity, are characteristic of an illicit server (often a Remote Access Trojan or RAT). This type of malware allows an attacker to remotely control the compromised computer, leading to these unusual and unauthorized behaviors. It essentially turns the victim's machine into a server controlled by the attacker.
Question 5: What often connects wirelessly or via a mobile network, has an SSD (solid-state drive), and makes use of a touch screen for input?
- Laptop
- Portable media player
- Tablet (Correct answer)
- Netbook
Correct answer: Tablet
A tablet is a mobile computing device that typically features a touchscreen for input, often connects wirelessly (Wi-Fi or mobile network), and commonly uses a solid-state drive (SSD) for storage. These characteristics distinguish it from laptops, portable media players, and netbooks. Its design prioritizes portability and touch-based interaction.
Question 6: What distinguishes a LAN from a WAN?
- A LAN typically provides slower network connection speeds than a WAN.
- A WAN is a group of networked computers within a confined geographic area.
- A WAN is commonly used for intra-office communication.
- A LAN is a group of networked computers within a confined geographic area. (Correct answer)
Correct answer: A LAN is a group of networked computers within a confined geographic area.
A Local Area Network (LAN) is defined by its limited geographic scope, typically connecting devices within a single building, home, or campus. In contrast, a Wide Area Network (WAN) spans larger geographical distances, connecting multiple LANs over cities, states, or even countries. This distinction in physical coverage is the primary difference between the two network types.
Question 7: Which of the following is required to build a WAN?
- A Channel Service Unit/Data Service Unit (CSU/DSU)
- A hub
- A router (Correct answer)
- A bridge
Correct answer: A router
A router is essential for building a WAN because it connects different networks and directs data traffic between them. Routers operate at Layer 3 of the OSI model, using IP addresses to determine the best path for data packets across geographically dispersed networks. While other devices connect within a single network segment, a router is necessary to interconnect distinct networks into a WAN.
