Which of the following causes an evident loss of decibel?

Increased attenuation

Which types of cables are mainly used in elevator shafts that can prevent fire?

Riser-rated Notes: Riser-rated cables are used in cable risers and elevator shafts where you cannot use plenum cables. Riser-rated cables have the self-extinguish capability to stop the fire from spreading through the cable, which means that the fire cannot spread vertically. Plenum-rated cables are used in offices, other commercial and residential complexes. PVC-rated cables cannot prevent a fire even though they can be used in multiple places. Fiber cables are not used in elevator shafts and do not prevent fire. They are used for high-speed data transmission.

Which type of cable has an RJ45 (male) at one end and a DB9 (female) connector at the other end? [Choose all that apply]

Rollover Cable, Console Cable Notes: A crossover cable is used for connecting two similar devices without a switch or hub. A crossover cable is required to connect both of them for data transmission. A crossover cable is also used to cascade switches. A straight cable is used for network connectivity and data transmission.

Which of the following is the data rate that defines the amount of data transmitted in a specific time?

Throughput

What is the maximum speed of the CAT1 cable?

Up to 1 Mbps Note: CAT2 - Up to 4 Mbps CAT3 - Up to 10 Mbps CAT4 - Up to 16 Mbps CAT5 - Up to 100 Mbps CAT5e - Up to 10 Gbps CAT6 - Up to 10 Gbps CAT6a - Up to 10 Gbps CAT7 - Up to 10 Gbps
