This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: Networking
Prompt focus: A technician needs to connect a workstation to the network and wants the fastest reliable copper Ethernet connection over a 90 meter run. Which cabling standard should be selected to support 10 Gbps at that distance?
Why the correct answer works
Cat 6a cabling, which supports 10 Gbps over the full 100 meter distance
Cat 6a is specifically engineered to deliver 10GBASE-T over the full 100 meter distance, easily covering a 90 meter run.
Why the tempting wrong answer fails
The tempting wrong answer usually loses because it skips the key condition, priority, or evidence in the prompt.
Plain-language takeaway
Cat 6a is the lowest-grade twisted-pair standard that reliably carries 10GBASE-T across the full 100 meter horizontal run because its tighter twists and improved shielding reduce alien crosstalk. Cat 6 can carry 10 Gbps but only over shorter distances, typically around 55…
Simple analogy
Think of networking like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
How to review it before a retake
- Underline the command word and name what the question is asking before rereading the choices.
- Compare the correct answer against the closest distractor and write the exact detail that separates them.
- Retest this objective with a fresh question without looking at the rationale first.
