Question: What is the primary purpose of a subnet mask in a network?
Answer: ✔✔ A subnet mask is used to divide an IP address into network and host portions,
enabling devices to determine whether a destination IP address is on the same local network or
requires routing to a different network.
Question: How does a router differ from a switch in a network?
Answer: ✔✔ A router connects different networks and directs data between them, while a switch
connects devices within the same network and manages data traffic between those devices based
on MAC addresses.
Question: What is the function of the DNS in networking?
Answer: ✔✔ The Domain Name System (DNS) translates human-readable domain names (like
www.example.com) into IP addresses that computers use to identify and communicate with each
other on the network.
Question: What is the purpose of NAT in a network?
1
,Answer: ✔✔ Network Address Translation (NAT) allows multiple devices on a local network to
share a single public IP address for accessing external networks, such as the internet, enhancing
security and conserving IP addresses.
Question: Explain what a VPN is and its primary use.
Answer: ✔✔ A Virtual Private Network (VPN) creates a secure, encrypted connection over a
less secure network, such as the internet, allowing users to access network resources remotely
while protecting their data and privacy.
Question: What does the acronym TCP/IP stand for, and why is it important?
Answer: ✔✔ TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is a
fundamental suite of communication protocols that enables data exchange over networks,
including the internet, by defining how data packets are transmitted and routed.
Question: What is the role of a DHCP server in a network?
Answer: ✔✔ A Dynamic Host Configuration Protocol (DHCP) server automatically assigns IP
addresses and other network configuration parameters to devices on the network, simplifying
network management and reducing manual configuration.
Question: Describe the difference between IPv4 and IPv6.
2
,Answer: ✔✔ IPv4 uses 32-bit addresses and is limited to about 4.3 billion unique addresses,
while IPv6 uses 128-bit addresses, providing a vastly larger address space and improved features
for modern networking needs.
Question: What is the purpose of the OSI model in networking?
Answer: ✔✔ The OSI (Open Systems Interconnection) model provides a conceptual framework
for understanding and designing network communication by dividing it into seven layers, each
responsible for different aspects of data transmission.
Question: How does a firewall protect a network?
Answer: ✔✔ A firewall monitors and controls incoming and outgoing network traffic based on
predetermined security rules, helping to prevent unauthorized access and protect the network
from potential threats.
Question: What is a VLAN and how does it benefit network management?
Answer: ✔✔ A Virtual Local Area Network (VLAN) segments a physical network into multiple
logical networks, improving network management, enhancing security, and reducing broadcast
traffic by isolating different network segments.
Which of the following describes a server-based network?
3
, a. A configuration of nodes, some of which are dedicated to providing resources to other hosts on
the network
b. A peer-to-peer file sharing protocol used for distributing large amounts of data
c. Workstations that use add-on software to participate in large, decentralized networks that are
usually located on the Internet
d. Groups of clients that communicate with one another to create a network that has no single
central database ✔✔a
Which of the following is true about packets?
a. When a sending host creates a packet, the process begins with Layer 7 of the OSI/RM and
continues through Layer 1.
b. When a sending host creates a packet, the process begins with Layer 1 of the OSI/RM and
continues through Layer 7.
