Jason would like the fastest internet available at his house, and he called his local fiber-optic provider. Which of the following offers would provide the fastest service to Jason's home network?

FFTH - "Fiber to the X" (FTTx) is commonly used to describe where the fiber connection ends between the service and the subscriber. The closer the fiber is to the user's network, the faster the service. FTTH (fiber to the house) provides fiber directly to the user's home network making it the fastest option. Traditionally, you will find 1 Gbps connections or higher with FTTH. FTTN (fiber to the node) or FTTC (fiber to the curb/cabinet) provides fiber only to the local area or neighborhood but then uses copper cabling from the node/cabinet/curb to the home network, which slows down the network (generally, 100-200 Mbps). HFC (Hybrid Fiber Coax) is similar to FTTN/FTTC, except that coaxial cable is used from the cabinet to the home to increase the speed (generally 300-500 Mbps).

The large multi-function network printer has recently begun to print pages that appear to have a dust-like coating when handled by the users. Which of the following components should be replaced based on this description?

The fuser rolls the paper to the output tray, and you have your finished page. The fuser also heats the paper itself, of course, which is why pages are always hot when they come out of a laser printer or photocopier. If the paper feels dusty or the toner doesn't adhere to the printer, this usually indicates a failing fuser that needs to be replaced.
