GAQM CFA-001 Exam - Topic 2 Question 77 Discussion

An Internet standard protocol (built on top of TCP/IP) that assures accurate synchronization to the millisecond of computer clock times in a network of computers. Which of the following statement is true for NTP Stratum Levels?
D) A stratum-3 server gets its time over a network link, via NTP, from a stratum-2 server, and so on
A) Stratum-0 servers are used on the network; they are not directly connected to computers which then operate as stratum-1 servers
B) Stratum-1 time server is linked over a network path to a reliable source of UTC time such as GPS, WWV, or CDMA transmissions
C) A stratum-2 server is directly linked (not over a network path) to a reliable source of UTC time such as GPS, WWV, or CDMA transmissions

Stratum-0 servers are just reference clocks, not connected directly.

Stratum-3 servers rely on stratum-2, right? Makes sense.

Wait, stratum-2 isn't directly linked? That seems off.

I’m a bit confused about stratum-3; I thought it just gets time from stratum-2 servers, but I can't recall if it's over a network link or not.

I practiced a similar question about NTP stratum levels, and I feel like stratum-2 servers do rely on network paths to get their time.

I think stratum-1 servers are directly connected to reliable time sources like GPS, which makes option B sound correct to me.

I remember studying that stratum levels indicate the distance from the reference clock, but I'm not entirely sure about the specifics of stratum-0 and stratum-1.

Okay, I think I've got it now. B is the correct answer - stratum-1 servers are directly linked to a reliable time source like GPS or CDMA.

That's a good point, Polly. I think option A is describing stratum-0 as the time source, and stratum-1 servers are the ones directly connected to it. So B seems like the most accurate statement.

I'm a bit confused about the difference between stratum-0 and stratum-1. Is stratum-0 just the time source, and stratum-1 is the first level of servers connected to it?

Okay, let me think this through. I know that stratum-1 servers are directly connected to a reliable time source, so that's option B. The other options seem to be describing the relationships between the different stratum levels.

Okay, I've got this. A fax machine is usually a pretty compact piece of office equipment, so I'm going to go with option A - 0.2 sq m (2 sq ft).

B. Stratum-1 time server is linked over a network path to a reliable source of UTC time. Simple and straightforward, just the way I like my networking protocols.
