Question 42Which one of the following statements correctly describes the SFP (Small Form-Factorpluggable) + transceiver?a. SFP+ provides the same function as GBICs (Gigabit Interface Converter) and is morecompact. It is theoretically capable of 5 Gbps.b. SFP+ supports up to 10 Gbps and is slightly larger than SFP, with lower powerconsumption than XFP.c. SFP+ is the same size as SFP and supports a theoretical maximum transmission speed of16 Gbps.d. SFP+ complies with the 802.3ba standard, allowing four channels in a single transceiverand supporting up to 40 Gbps data rates.Question 43What type of fiber cable problem is caused when pairing a 50-micron core cable with a 62.5micron core cable?a. Fiber type mismatchb. Dirty connectorsc. Wavelength mismatchd. TX/RX reverseQuestion 44How does refraction affect the propagation of a wireless transmission?a. It distorts the signal as it travels into and through a different transmission medium.b. It splits the signal into secondary waves that continue in the direction in which they split.c. It causes the signal to be returned back towards the source of the origin.d. It causes the signal to be absorbed by the refracting material.Question 45When using RFID (Radio Frequency Identification), what is an ARPT (Active Reader PassiveTag)?a. It is a battery-powered tag actively transmits its credentials at regular time intervals, whichcan be read remotely.b. It is a tag that requires an active reader, but still contains a battery in the tag.c. It is a tag that is activated by an active reader, and uses power from the reader's radiowaves to power its transmission.d. It is a tag that can be read remotely up to a distance of 50 m, but requires a powerfulactive reader.Question 48You have just settled in for some study time at the local coffee shop, and you pause longenough to connect your smartphone to the Wi-Fi so you can listen to some music while youstudy.
