CCNA Flashcards - Network Fundamentals - Compare physical interface and cabling types
-
Hello,
I have a question regarding some questions that are present in flashcards. There are some questions regarding PINS on WAN cable interfaces and I can't seem to find any information regarding those cables in CCNA or network fundamentals courses. I must admit that I haven't watched every video yet, but there's no mention of these cables in those I have watched. When I open flashcards to practice these questions appear on network fundamentals. Thanks

Hey @Aleksander-Maslarić great question, can you give me the specific cable interfaces such as SFP/QSFP, SONET, etc? I will look into it for you.

Hey, thanks for your reply. Sure, the questions are:
How many pins are on an EIA/TIA-232 WAN cable interface?
How many pins are on a V.35 WAN cable interface?
How many pins are on an EIA/TIA-530 WAN cable interface?
How many pins are on an EIA/TIA-449 WAN cable interface?
How many pins are on an X.21 WAN cable interface?and potentially Which device connects the 4-wire cable of the ISP WAN and the router? I've seen some information about CSU/DSU but can't recall what exactly.
Thanks!
