Hello Protocol
Correct Answer
A. BPDUsExplanation
Switches employing the Spanning-Tree Protocol use BPDUs (Bridge Protocol Data Units) to communicate. BPDUs are messages that switches send to each other to exchange information about the network topology and to determine the best path for forwarding network traffic. By exchanging BPDUs, switches can detect and prevent loops in the network, ensuring a loop-free and redundant network infrastructure.Rate this question:

What technology allows 24 DS0 channels to be combined into a single DS1 or T1 channel?
-
Wide Area Networking
-
Signaling Over Time
-
Time-Division Multiplexing
-
Channel-Aggregation Sequencing
Correct Answer
A. Time-Division MultiplexingExplanation
Time-Division Multiplexing is the technology that allows 24 DS0 channels to be combined into a single DS1 or T1 channel. This technique divides the available bandwidth into multiple time slots, with each slot being assigned to a different channel. By rapidly switching between these channels, data from multiple sources can be transmitted over a single communication line, maximizing the utilization of the available bandwidth.Rate this question:

Which networking technology uses dual counter-rotating token-passing ring networks?
-
Ethernet
-
Token Ring
-
FDDI
-
SNA
Correct Answer
A. FDDIExplanation
FDDI (Fiber Distributed Data Interface) is the correct answer because it is a networking technology that uses dual counter-rotating token-passing ring networks. FDDI is a high-speed LAN technology that uses optical fiber to transmit data. It employs a dual-ring architecture where data is transmitted in one direction on one ring and in the opposite direction on the other ring. This dual counter-rotating ring design provides redundancy and fault tolerance, ensuring reliable data transmission.Rate this question:

What does "OC" stand for in an OC-3?
-
Optimal Communications
-
Optical Communications
-
Optimal Carrier
-
Optical Carrier
Correct Answer
A. Optical CarrierExplanation
"OC" stands for "Optical Carrier" in an OC-3. The term "Optical Carrier" refers to a standardized unit of transmission capacity in fiber optic networks. In this context, OC-3 represents a specific transmission rate of 155.52 Mbps (megabits per second). The use of "Optical Carrier" highlights the use of optical fibers for transmitting data, emphasizing the technology and medium involved in the communication process.Rate this question:

What standard developed by Novell and Apple is similar to the NDIS specification?
-
EtherTalk
-
Open Data-link Interface (ODI)
-
IPX/SPX
-
AppleTalk
Correct Answer
A. Open Data-link Interface (ODI)Explanation
Open Data-link Interface (ODI) is the correct answer because it was a standard developed by Novell and Apple. ODI was designed to provide a common interface for network drivers, similar to the NDIS (Network Driver Interface Specification) developed by Microsoft. It allowed different network protocols, such as IPX/SPX and AppleTalk, to be supported by the same network interface card. Therefore, ODI is similar to the NDIS specification in terms of providing a standardized interface for network drivers.Rate this question:

What organization is credited with developing the OSI Reference Model in 1974?
-
IEEE
-
ISO
-
ANSI
-
ITU
Correct Answer
A. ISOExplanation
ISO, the International Organization for Standardization, is credited with developing the OSI Reference Model in 1974. The OSI (Open Systems Interconnection) Reference Model is a conceptual framework that standardizes the functions of a communication system into seven layers. ISO, being a global standard-setting organization, played a crucial role in establishing this model, which has since become a widely accepted framework for understanding and implementing network protocols.Rate this question:

What is another term for "physical address" on a TCP/IP network?
-
IP Address
-
MAC Address
-
Network Jack
-
Home Address
Correct Answer
A. MAC AddressExplanation
A physical address on a TCP/IP network is commonly referred to as a MAC address. MAC stands for Media Access Control, and it is a unique identifier assigned to network interfaces, such as network cards or Ethernet ports, by the manufacturer. The MAC address is used to identify and communicate with devices on a local network. Unlike an IP address, which can change, the MAC address is permanent and cannot be easily altered.Rate this question:

In which type of switching is the entire packet received and checked before sending it?
-
Cut-Through
-
Store-And-Forward
-
FragmentFree
-
Low Latency
Correct Answer
A. Store-And-ForwardExplanation
Store-And-Forward switching is the type of switching where the entire packet is received and checked for errors before it is forwarded to the destination. In this method, the switch buffers the entire packet and performs a CRC (Cyclic Redundancy Check) to verify the integrity of the packet. If the packet is error-free, it is then forwarded to the destination. This method ensures that only error-free packets are transmitted, reducing the chances of data corruption or loss.Rate this question:
