9. What is the full form of UDP with reference to TCP/IP ?
Correct : D
Explanation: UDP stands for User Datagram Protocol. It is a Transport Layer Protocol that is part of the Internet Protocol Suite. UDP is an alternative communication protocol over TCP (Transmission Control Protocol).
10. In which of the following network topologies, all the nodes are connected to a centerl connection point (like a hub, or a swithc) ?
JOA-IT 817 *
Correct :
Explanation: In a star topology, each device only needs one link and one I/O port to connect to other devices. This makes it easy to add new nodes without restarting all the other devices.
11. Which of the following is transmission media make use of four pairs of insulated copper wires ?
JOA-IT 817 *
Correct : A
Explanation : Unshielded twisted pair (UTP) cables are transmission media that use four pairs of insulated copper wires. UTP cables are made up of eight strands of copper wire, organized into four pairs. The wires are twisted to protect them from interference. UTP cables with two pairs use RJ-11 connectors, and four-pair cables use an RJ-45 connector.
12. Which of the following Internet services is responsible for translation of domain names into corresponding IP address ?
JOA-IT 817 *
Correct : B
Explanation: The Domain Name System (DNS) is an internet service that translates domain names into IP addresses. The DNS system works like a phone book, managing the mapping between names and numbers. For example, when a user types a web address (URL) into a browser, DNS servers return the IP address of the web server associated with that name.
13. In which of the following networks, the problem of hidden terminal arises ?
Correct : A
Explanation: The hidden terminal problem occurs in wireless local area networks (LANs). It's a transmission problem that happens when two or more stations that are out of range of each other transmit simultaneously to a common recipient.
14. What is the length in bits of an IPv6 address ?
Correct : D
Explanation: Internet Protocol version 6 (IPv6) is a set of standard protocols for the Internet's network layer. It's the most recent version of the Internet Protocol (IP). All IPv6 addresses are 128 bits long, written as 8 sections of 16 bits each.
15. The concept of IP address belongs to the ____ layer of ISO-OSI reference model.
JOA-IT 817 *
Correct : B
Explanation: The concept of IP address belongs to the Network Layer (Layer 3) of the ISO-OSI reference model. The Open Systems Interconnection (OSI) model is a framework that describes how information moves between computing devices in a network. The OSI model was first developed in 1978. OSI 7 layers are Physical, Data Link, Network, Transport, Session, Presentation, and Application.
16. What is the recommend maximum length of UTP CAT 6 cable ?
JOA-IT 817 *
Correct : D
Explanation: The recommended maximum length for a CAT6 cable is 100 meters (328 feet) when communicating at up to 1000 megabits (1 gigabit). This length ensures reliable high-speed data transmission for Gigabit Ethernet (1000BASE-T) networks.
17. How many usable IPv4 addresses are there in a network with subnet mask 255.255.255.240 ?
JOA-IT 817 *
Correct : C
Explanation:
18. In which mode of communicaton, transmission can occur in both directions but only in one direction at a time ?
JOA-IT 817 *
Correct : B
Explanation: Half-duplex communication is a mode of communication where transmission can occur in both directions, but only in one direction at a time. In this mode, data can be sent and received, but not at the same time.
19. GSM, UMTS and LTE are the types of
JOA-IT 817 *
