FREE BDS Network Design Questions and Answers
What is the primary purpose of a headend in a broadband distribution network?
The headend is the control center in a broadband distribution network where content is collected and distributed to subscribers.
What type of network topology is most commonly used in broadband distribution networks?
Tree topology, also known as hierarchical topology, is commonly used in broadband distribution networks to efficiently manage signal distribution and routing.
Which component is used to split a broadband signal into multiple paths without significant signal loss?
A splitter is used to divide a broadband signal into multiple paths, allowing distribution to multiple devices without significant signal loss.
What is the main advantage of using a hybrid fiber-coaxial (HFC) network?
HFC networks combine the high-speed data transfer capabilities of fiber optics with the widespread availability of coaxial cables.
Which protocol is often used for managing and configuring devices in a broadband distribution network?
Simple Network Management Protocol (SNMP) is commonly used for managing and configuring network devices, monitoring network performance, and detecting faults.
What is the primary function of a DOCSIS standard in broadband networks?
The DOCSIS (Data Over Cable Service Interface Specification) standardizes the interfaces for data transmission over cable television systems.
In the context of broadband network design, what does QoS stand for?
Quality of Service (QoS) refers to the overall performance of a network service, particularly the ability to guarantee certain levels of bandwidth and latency.
In broadband network design, what is the purpose of an optical node?
An optical node converts the optical signals transmitted through fiber optics to electrical signals for distribution over coaxial cables.
What does the term "fiber to the home" (FTTH) refer to in network design?
FTTH refers to the installation of fiber optic cables directly to individual residences, providing high-speed internet access.
What device is used to boost weak signals in a broadband distribution network?
An amplifier is used to boost weak signals in a broadband distribution network to ensure they reach the end devices without significant loss in quality.
What is the main function of a modem in a broadband distribution network?
A modem modulates and demodulates digital signals to and from analog signals for transmission over telephone lines or cable systems.
