Every question is scheduled around your memory, not a fixed drill order. Miss one and it comes back sooner. Nail it and it stays out of your way. You never waste a session re-answering what you already know, and the shaky stuff shows up again just as it starts to fade.
2,700+ original questions: 736 for CCNA 200-301, 992 across both A+ Cores, 504 for Network+, and 502 for Security+. Each one is mapped to a numbered objective on the current blueprint, and when you miss one you get an actual explanation of why the right answer is right — and why yours wasn't.
Every objective, numbered like the blueprint, with counts you can audit.
Timed, weighted by domain the way the actual exam is, and no feedback until the results screen, just like test day. Afterward, walk through everything you missed and see which domains need work — so booking is a decision, not a gamble.
Tap an answer — this is exactly how it works in the app, explanation and all.
A technician terminates both ends of a patch cable using the T568B pinout. Which of the following BEST describes the resulting cable?
✗ Not this one. A crossover uses T568A on one end and T568B on the other — that mismatch is the whole trick of this question.
✗ Not this one. Rollover (console) cables reverse the entire pin order end to end — for managing gear, not carrying traffic.
✓ Right. The same standard on both ends — T568B here — makes a straight-through cable, the normal patch cable from a host to a switch.
✗ Not this one. A loopback plug wires transmit back to receive on the same connector, for testing a single port.
A+ Core 1, domain 2.0 Networking. One of 2,734.
