NTA Question Bank 1 with Complete
Solutions
Question: What is the primary purpose of a subnet mask in networking?
Answer: ✔✔ The primary purpose of a subnet mask is to divide an IP address into the network
and host portions, which helps in routing packets within the network and identifying the subnet
to which a device belongs.
Question: How does Network Address Translation (NAT) benefit a private network?
Answer: ✔✔ NAT allows multiple devices on a private network to share a single public IP
address for accessing the internet, thereby conserving IP addresses and enhancing security by
hiding internal IP addresses.
Question: What is the function of the Domain Name System (DNS) in a network?
Answer: ✔✔ DNS translates human-readable domain names into IP addresses, allowing users to
access websites using easy-to-remember names instead of numerical IP addresses.
Question: What distinguishes TCP from UDP in terms of data transmission?
1
, Answer: ✔✔ TCP (Transmission Control Protocol) provides reliable, connection-oriented data
transmission with error-checking and flow control, while UDP (User Datagram Protocol) offers
faster, connectionless communication with minimal overhead and no guarantee of delivery.
Question: What role does a router play in a network?
Answer: ✔✔ A router connects different networks, directs data packets between them, and
manages traffic to ensure efficient and accurate delivery of data across network boundaries.
Question: How does a Virtual Local Area Network (VLAN) improve network management?
Answer: ✔✔ VLANs improve network management by segmenting a larger physical network
into smaller, logical groups, which enhances security, reduces broadcast traffic, and simplifies
network administration.
Question: What is the purpose of a firewall in network security?
Answer: ✔✔ A firewall monitors and controls incoming and outgoing network traffic based on
predetermined security rules, helping to protect the network from unauthorized access and cyber
threats.
Question: What is the significance of IP address classes in networking?
