Network Fundamentals Flashcards

According to ICC standards, which pathway method is commonly used to support structured cabling in commercial buildings?

Answer: Cable tray, conduit, and innerduct systems

Commercial buildings typically use cable trays, conduit systems, and innerduct to properly support, protect, and organize structured cabling infrastructure per ICC and ANSI/TIA standards.

What is the minimum bend radius requirement for a 4-pair UTP cable during installation?

Answer: 4 times the cable diameter

UTP cable must maintain a minimum bend radius of 4 times the cable's outer diameter during installation to prevent damage to the internal wire pairs and signal degradation.

Which standard defines the telecommunications cabling infrastructure for commercial buildings in the US?

Answer: ANSI/TIA-568

ANSI/TIA-568 is the US standard that specifies requirements for telecommunications cabling systems in commercial buildings, covering cable types, connectors, and performance.

In a building's network infrastructure, what is the MDF?

Answer: Main Distribution Frame — the primary cross-connect for the building

The Main Distribution Frame (MDF) is the central hub of a building's structured cabling system where backbone cables from IDFs terminate and connect to core network equipment.

What network topology connects each device to exactly two other devices, forming a closed loop?

Answer: Ring

A ring topology connects each device to exactly two neighbors, forming a circular data path where signals travel in one or both directions around the ring.

Which IPv4 address range is reserved for Automatic Private IP Addressing (APIPA) when a DHCP server is unavailable?

Answer: 169.254.0.0 – 169.254.255.255

APIPA automatically assigns addresses in the 169.254.0.0/16 range when a device cannot reach a DHCP server, enabling local network communication without manual configuration.

What does QoS (Quality of Service) prioritize in a converged network carrying voice, video, and data?

Answer: Time-sensitive traffic like VoIP and video streaming

QoS mechanisms prioritize time-sensitive traffic such as VoIP and video conferencing to minimize latency and jitter, ensuring acceptable quality for real-time communications.
