CompTIA Network+ Certification Exam N10-009 Practice Test 7

In 10GBASE-T networks, Cat 6 cabling supports a 10 Gbps data transfer rate at a limited range of 33-55 meters, whereas Cat 6A (Augmented) cabling allows for a 10 Gbps data transfer rate over a cable segment length of 100 meters.

True

Which of the answers listed below refers to the maximum data transfer rate for Cat 7 cabling over a standard 100-meter cable segment length?

10 Gbps

Which of the following answers refer(s) to the characteristics of Category 8 (Cat 8) cabling? (Select all that apply)

25GBASE-T, Optimized for data center equipment , 40GBASE-T, Short-distance (approx. 30 meters), high-speed links

This type of cabling supports speeds of up to 1 Gbps (or higher with DOCSIS technology) and is commonly used for both television and broadband Internet access.

Coaxial cabling

Which of the answers listed below refers to speed/distance limitations of twinaxial cabling?

Any of the above

Which of the following answers refers to a LED-based cabling type supporting speeds of up to 400 Gbps over short-range connections?

Multimode cabling

Which cabling type uses laser technology for long-distance communication links that support data transmission rates of up to 400 Gbps?

Single-mode cabling

A type of enclosed space in a building, such as the one between a dropped ceiling and the structural ceiling, used for air handling, is commonly referred to as a plenum space. A special type of cabling with a fire-retardant jacket, designed for use in that space, is known as plenum-rated cabling. Materials from which the plenum-rated cable's cover is made include low-smoke Polyvinyl Chloride (PVC) and Fluorinated Ethylene Polymer (FEP).

True

Which of the answers listed below refers to an OSI Layer 1 device designed to provide a seamless link between different types of network interfaces?

Transceiver

Which of the following network technologies is commonly used in data centers to provide high-speed connections between servers and data storage devices?

Fibre Channel

Which of the answers listed below refer(s) to SFP and QSFP? (Select all that apply)

Modular (hot swappable) interface, Converts electrical signals to optical signals , Small form factor transceiver , Converts optical signals to electrical signals

Which of the following answers refer(s) to (an) example(s) of (a) fiber-optic connector(s)? (Select all that apply)

LC, ST, SC, MPO

Which of the answers listed below refer to the RJ11 connector? (Select 3 answers)

Telephone equipment, Dial-up networking, Twisted-pair copper cabling

What are the characteristic features of the RJ45 connector? (Select 2 answers)

Twisted-pair copper cabling, Ethernet network cabling

Which of the following answers refer to the F-type connector? (Select 3 answers)

Threaded (screw-on) connector, Satellite/cable TV, broadband Internet connections via cable modems , Coaxial cabling

What are the characteristic features of the BNC connector? (Select 3 answers)

Coaxial cabling, Professional audio and video equipment, CCTV systems, laboratory, and testing equipment , Bayonet-style (twist-and-lock) connector

Which connector type features multiple fibers (up to 72) in a single ferrule and is most commonly used in data centers and high-speed networks?

MPO

A network topology where each node has a direct physical connection to every other node is called:

Mesh

Which type of network topology provides the highest level of redundancy?

Mesh

A type of network topology that combines two or more standard network topologies is referred to as a hybrid network topology.

True

A star topology is a network topology commonly used in LANs. In a star topology, each node is connected directly to a central hub or switch. A hub-and-spoke topology, often used in WANs and VPNs, is a variation of the star topology. In a hub-and-spoke topology, a central hub connects to multiple spokes, each leading to different nodes, which offers slightly better fault tolerance than the star topology, as the failure of a single spoke does not disrupt the entire network.

True

Which of the answers listed below refers to a two-layer, full-mesh topology commonly used in data centers?

Spine and leaf

Which of the following examples does not fit the definition of a point-to-point topology?

Wi-Fi networks

In the three-tier hierarchical model, the layer providing the backbone for the entire network is referred to as:

Core layer

Which of the answers listed below refer to the distribution layer of the three-tier hierarchical model? (Select 2 answers)

Acts as an intermediary between the core and access layers, Provides routing, filtering, and traffic management functions
