Answer: A. 192.168.1.1

Explanation: 192.168.1.1 is a valid IPv4 address. The IPv4 address format consists of four decimal numbers separated by dots, each ranging from 0 to 255.

Question 5:

What is the purpose of subnetting in IP networks? A. To increase the number of available IP addresses
B. To improve network security by hiding internal IP addresses
C. To divide a larger network into smaller, more manageable segments
D. To encrypt data packets for secure transmission

Answer: C. To divide a larger network into smaller, more manageable segments

Explanation: Subnetting is used to divide a larger network into smaller sub-networks, making it easier to manage and improving network performance and security.

Question 6:

Which of the following commands would you use to test the connectivity between two devices on a network? A. ipconfig
B. netstat
C. ping
D. tracert

Answer: C. ping

Explanation: The ping command is used to test the connectivity between two network devices by sending ICMP echo requests and waiting for a response.

Question 7:

Which network topology connects all devices in a network to a single central hub? A. Star
B. Ring
C. Bus
D. Mesh

Answer: A. Star

Explanation: In a star topology, all devices are connected to a single central hub or switch, which acts as the central point of communication for all devices.

Question 8:

What is the primary purpose of the Domain Name System (DNS)? A. To assign IP addresses to devices
B. To resolve domain names to IP addresses
C. To filter unwanted traffic
D. To encrypt data transmissions

Answer: B. To resolve domain names to IP addresses

Explanation: DNS translates human-readable domain names (like www.example.com) into IP addresses (like 192.168.1.1), allowing devices to locate and communicate with each other over the Internet.

Question 9:

Which protocol is used to securely transfer files over a network? A. FTP
B. TFTP
C. SFTP
D. SMTP

Answer: C. SFTP

Explanation: Secure File Transfer Protocol (SFTP) is used to securely transfer files over a network, providing encryption and secure authentication.

Question 10:

What does NAT (Network Address Translation) do in a network? A. Filters incoming and outgoing traffic
B. Translates private IP addresses to public IP addresses and vice versa
C. Encrypts data before transmission
D. Creates virtual private networks

Answer: B. Translates private IP addresses to public IP addresses and vice versa

Explanation: NAT translates private IP addresses used within a local network to public IP addresses for communication over the Internet and vice versa, allowing multiple devices to share a single public IP address.

Question 11:

Which of the following is a characteristic of a VLAN (Virtual Local Area Network)? A. It operates at the physical layer of the OSI model
B. It segments a network into smaller broadcast domains
C. It encrypts data to ensure secure transmission
D. It increases the physical size of a network

Answer: B. It segments a network into smaller broadcast domains

Explanation: VLANs operate at the data link layer (Layer 2) and segment a network into smaller, isolated broadcast domains, which helps in managing network traffic and improving security.

Question 12:

What is the primary purpose of the ARP (Address Resolution Protocol)? A. To translate domain names into IP addresses
B. To resolve IP addresses to MAC addresses
C. To assign IP addresses to devices
D. To provide secure remote access to a network

Answer: B. To resolve IP addresses to MAC addresses

Explanation: ARP is used to map a known IP address to a MAC address, allowing devices to communicate within a local network.

Question 13:

Which layer of the OSI model is responsible for end-to-end communication and error recovery? A. Transport
B. Network
C. Data Link
D. Application

Answer: A. Transport

Explanation: The Transport layer (Layer 4) is responsible for end-to-end communication, error recovery, and flow control, ensuring reliable data transfer between devices.

Question 14:

Which of the following is a benefit of using IPv6 over IPv4? A. Shorter address length
B. Built-in encryption
C. Larger address space
D. Simplified subnetting

Answer: C. Larger address space

Explanation: IPv6 provides a significantly larger address space compared to IPv4, allowing for a greater number of unique IP addresses, which is essential for the growing number of devices connected to the internet.

Question 15:

What is the purpose of a DHCP relay agent? A. To translate IP addresses between different subnets
B. To forward DHCP requests and responses between clients and servers on different subnets
C. To encrypt DHCP messages for secure transmission
D. To filter DHCP traffic based on predefined rules

Answer: B. To forward DHCP requests and responses between clients and servers on different subnets

Explanation: A DHCP relay agent forwards DHCP requests and responses between clients and servers located on different subnets, enabling DHCP clients to receive IP configuration from a centralized DHCP server.

Question 16:

Which type of cable is commonly used to connect a computer to a switch or hub in an Ethernet network? A. Coaxial cable
B. Fiber optic cable
C. Crossover cable
D. Straight-through cable

Answer: D. Straight-through cable

Explanation: A straight-through Ethernet cable is commonly used to connect devices such as computers to network switches or hubs, as the pinout configuration on both ends of the cable is identical.

Question 17:

What does the term "MTU" stand for in networking, and what does it signify? A. Maximum Transmission Unit; the largest size of a packet that can be transmitted
B. Minimum Transmission Unit; the smallest size of a packet that can be transmitted
C. Maximum Transfer Usage; the total data usage limit for a network
D. Minimum Transfer Usage; the minimum data usage for a network session

Answer: A. Maximum Transmission Unit; the largest size of a packet that can be transmitted

Explanation: MTU stands for Maximum Transmission Unit and represents the largest size of a data packet that can be transmitted over a network medium without fragmentation.

Question 18:

Which command is used to display the current TCP/IP network configuration of a computer? A. ipconfig (Windows)
B. ifconfig (Linux/Unix)
C. Both A and B
D. netstat

Answer: C. Both A and B

Explanation: The ipconfig command (on Windows) and the ifconfig command (on Linux/Unix) are used to display the current TCP/IP network configuration, including IP address, subnet mask, and default gateway.

Question 19:

What is the main advantage of using dynamic routing protocols over static routing? A. Reduced administrative overhead
B. Greater control over routing paths
C. Simplified network security
D. Improved data encryption

Answer: A. Reduced administrative overhead

Explanation: Dynamic routing protocols automatically adjust routes based on network changes, reducing the need for manual configuration and administrative overhead compared to static routing.

Question 20:
