a. a traditional analog/digital modem.

b. to connect the line directly to the Ethernet card in your computer.

c. a router.

d. a device referred to as a ‘digital’ modem.

For this question, probably D. But the test writer is an idiot.

   Technically, the answer is "D"

   However, you would then need to connect the line from the modem to the Ethernet card in your computer.

   Choices A and B are out. Choice C is the best, IMHO, but depending on what is meant by "digital modem," choice D *could* be correct. Frankly, I worked during the digital boom in Silicon Valley in the 90s when everybody was excited about ISDN, and don’t remember anybody ever calling the terminating devices "modems." Since the word "modem" is short for "modulator/demodulator," the implication is that the incoming signal needs to be changed from analog to digital. But since ISDN is already a digital signal, this isn’t the case. The correct term for an ISDN termination is NT1 (Network Terminator type 1). They are often included as part of a TA (Terminal Adapter), but can be separate units. A BRI or PRI interface on a router will often (in fact, probably 100% of the time since about 1998) have an NT1 built in, which I why I prefer choice C.

   So, just to reiterate, I don’t like the terminolgy of choice D, but if the course of study you’re taking refers to an NT1 (or TA) as a "digital" modem, then that may be the "right" answer for your class.
