SFP+ QSFP+ 10GBASE-SR GIGE-PON 13 / 25 What is the function of an SFP (Small Form-factor Pluggable) transceiver in a network? It converts electrical signals into optical signals for fiber-optic communication It converts digital signals into analog signals for long-distance transmission It amplifies the signals to extend transmission distance It allows Ethernet frames to be transmitted over coaxial cables 14 / 25 Which Ethernet standard operates at 10 Gbps and uses multi-mode fiber or direct attach copper cables? 802.3u 802.3ae 802.3bz 802.3an 15 / 25 What is the primary difference between plenum and non-plenum cables? Plenum cables are more durable and suitable for underground installations Non-plenum cables are rated for use in environments where fire safety is not a concern Plenum cables have better shielding than non-plenum cables Non-plenum cables can be used in air-handling spaces, while plenum cables cannot 16 / 25 Which type of cable is rated for use in air-handling spaces and is designed to minimize the risk of toxic fumes in the event of a fire? Plenum-rated cable Non-plenum-rated cable Direct burial-rated cable Outdoor-rated cable 17 / 25 Which type of cable is most commonly used for cable television and broadband Internet services? Coaxial cable Twinaxial cable Ethernet twisted-pair cable Fiber-optic cable 18 / 25 Which of the following is true about Twinaxial cables? They are commonly used for high-speed fiber connections in data centers They have better shielding than coaxial cables and are ideal for short-distance connections They are primarily used for long-distance communications, similar to fiber-optic cables They are not shielded and are prone to signal degradation 19 / 25 What type of cable is typically used for short-range, high-speed connections between servers and switches in data centers, providing high performance at a lower cost than fiber? Coaxial cable Direct Attach Copper (DAC) cable Single-mode fiber Ethernet twisted pair cable 20 / 25 What is the primary difference between single-mode fiber (SMF) and multimode fiber (MMF)? SMF uses a wider core diameter, allowing more data to be transmitted simultaneously MMF supports longer distances compared to SMF SMF uses a smaller core and is suited for long-distance transmission MMF is typically used for data centers, while SMF is used for local area networks 21 / 25 Which of the following IEEE 802.3 standards is commonly used for high-speed Ethernet networks, supporting speeds up to 100 Gbps? 802.3u 802.3z 802.3ae 802.3bm 22 / 25 Satellite communication typically has which of the following limitations?
