What is communications horizontal cabling?
Horizontal Cabling is the physical cabling and terminating hardware that provides the means of transporting data and voice signal between the Work Area Outlets and its horizontal cross-connect location in the Telecommunications Room (TR).
What is horizontal cabling in a structured cabling system?
Horizontal Cabling: The system of cabling that connects telecommunications rooms to individual outlets or work areas on the floor. Work Area Components: These connect end-user equipment to outlets of the horizontal cabling system.
What is horizontal and vertical cabling?
The horizontal option can secure the cables and keep them separated while within the rack. The vertical will keep everything in place while it goes up or down out of the server rack itself. Coming up with an effective cable management solution for your data center is important.
What is the maximum allowable distance for a horizontal cable?
The horizontal cabling shall be installed in a home run, star topology. It is preferred that a telecommunications room should be located on the same floor as the work areas served. The maximum horizontal distance shall be 76 meters (250 feet).
When terminating an Ethernet cable about how far should the cable sheath extend into the plug?
3/8 inch
When planning horizontal cabling What is the maximum allowable distance that can be used group of answer choices?
100 meters is the answer.
What does backbone cabling consist of group of answer choices?
What does backbone cabling consist of? The cables or wireless links that provide interconnection between the entrance facility and MDF, and between the MDF and IDFs.
What cable comes in two modes single mode and multi mode?
Fiber-optic cable is a form of cable that contains one or several glass or plastic fibers in its core and comes in two types: single-mode fiber (SMF) or multimode fiber (MMF).
Which of the following connectors is the most common for multimode fiber?
MT-RJ is the answer.
What is the maximum supported throughput of a Cat6 cable?
10Gbps

What does RG rating measure?
In a coaxial cabling, what does the RG rating measure? The materials used for shielding and conducting cores.
What is the fastest Ethernet standard that can?
10 Gigabit Ethernet is the fastest and most recent of the Ethernet standards. IEEE 802.3ae defines a version of Ethernet with a nominal rate of 10Gbits/s that makes it 10 times faster than Gigabit Ethernet. Unlike other Ethernet systems, 10 Gigabit Ethernet is based entirely on the use of optical fiber connections.
What is the fastest Ethernet standard that can possibly?
statistical time division multiplexing. What is the fastest Ethernet standard that can possibly be used on twisted-pair cabling? 10GBase-T.
What happens when a router receives a packet with a TTL of 0?
What happens when a router receives a packet with a TTL of 0? The router drops the packet and sends an ICMP TTL expired message back to the host. The hosts will still send and receive traffic, but traffic may not always reach the correct destination.
What happens when a router receives a packet?
When a router receives a packet, the router checks its routing table to determine if the destination address is for a system on one of it’s attached networks or if the message must be forwarded through another router. It then sends the message to the next system in the path to the destination.
Do IPv4 and IPv6 use the same packet format?
IPv4 and IPv6 use the same packet format. As a network support technician, you only need to know how to support IPv6. On IPv4 networks, IGMP operates at the Network layer of the OSI model to manage multicasting.
