Computer Networks Questions

Multiple choice technology
  1. Ethernet

  2. Internet

  3. Multiprotocol

  4. None of the above

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

To solve this question, the user needs to know the definition of a router and understand the concept of multiple protocols.

A router is a networking device that forwards data packets between computer networks. It uses headers and forwarding tables to determine the best path for forwarding the packets.

Multiple protocols refer to the ability of a router to handle different network layer protocols simultaneously.

Now, let's go through each option and explain why it is right or wrong:

A. Ethernet: This option is incorrect. Ethernet is a family of computer networking technologies commonly used in local area networks (LANs). Although routers may use Ethernet to connect to devices, Ethernet is not a term used to describe routers.

B. Internet: This option is incorrect. The Internet is a global network of networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. Although routers are used to forward data packets on the Internet, the term Internet is not used to describe routers.

C. Multiprotocol: This option is correct. A router that can handle multiple protocols is called a multiprotocol router. It is designed to handle different network layer protocols simultaneously, such as IP, IPX, and AppleTalk.

D. None of the above: This option is incorrect. The correct answer is C, as explained above.

The answer is: C

  1. True

  2. False

A Correct answer
Explanation

The data link layer (OSI Layer 2) is responsible for encapsulating packets from the network layer into frames for transmission over the physical medium. This is a fundamental networking concept - framing adds layer 2 headers and trailers for addressing and error detection.

  2. Access is controlled using WWN

  3. Contains ports and WWNs

  4. A collection of Zones

C Correct answer
Explanation

In SAN zoning, a Hybrid Zone is a configuration that combines different identification methods, such as physical port IDs and World Wide Names (WWNs), within the same zone definition.

  1. Telemanagement Forum

  2. Telecommunication Forum

  3. Telecom operation Forum

  4. None of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Telemanagement Forum (TM Forum) is a global industry association that develops standards and frameworks for telecommunications operations. They work on newer business models and operational frameworks, making them the correct answer among the options.

Multiple choice technology web technology
  1. Input Group, Output Group

  2. Input Group,Output Group, Default Group

  3. Output Group, Default Group, User Defined Group

  4. No groups were created

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Router transformations have two group types: Input Group (receives incoming data) and Output Group (routes data based on conditions). There is no separate Default or User Defined group type - these are routing conditions within Output Groups. Options B and C incorrectly include Default Group as a separate type.

  1. 802.5

  2. 802.3

  3. 802.11

  4. 802.16

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

IEEE 802.3 is the working group and standard that defines Ethernet. Other 802 standards cover different technologies: 802.5 is Token Ring, 802.11 covers Wi-Fi wireless networks, and 802.16 defines WiMAX broadband wireless. The 802.3 family specifically addresses wired Ethernet networking.

  4. 4

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In traditional Ethernet (10BASE5 and 10BASE2), the maximum number of repeaters allowed in a path between any two stations was 4, creating 5 segments. This is known as the 5-4-3 rule: 5 segments, 4 repeaters, with only 3 segments populated. This rule was designed to limit collision domain timing and ensure proper collision detection. The 4 repeaters (or 5 segments) limit was a fundamental constraint in classic coaxial Ethernet networks.

Multiple choice technology
  1. TCP provides virtual circuits and UDP does not

  2. UDP provides virtual circuits and TCP does not

  3. Both will not provide virtual circuits

  4. Both will provide

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

TCP is connection-oriented and establishes virtual circuits through three-way handshaking, ensuring reliable delivery. UDP is connectionless and sends datagrams without establishing virtual circuits, prioritizing speed over reliability. Options B, C, and D incorrectly state that UDP provides virtual circuits or that neither protocol uses them.

Multiple choice technology
  1. Asynchronous Connectionless

  2. Synchronous Connection-Oriented

  3. Radio waves

  4. UV

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bluetooth uses Synchronous Connection-Oriented (SCO) links for voice transmission because they provide guaranteed bandwidth and low latency required for real-time voice communication. Asynchronous Connectionless (ACL) links are for data, and radio waves/UV are transmission media, not Bluetooth link types.

Multiple choice technology
  1. PAN

  2. WAN

  3. Piconet

  4. LAN

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A Bluetooth network formed when devices connect is called a piconet. One device acts as master and up to 7 others as slaves. PAN (Personal Area Network) is a broader category that includes piconets. LAN, WAN are larger scale networks. The question specifically asks for the Bluetooth network name.
