Which Cable Connects Two Non-MDIX Switches?
A systems administrator has two network switches that need to be cabled together via copper cabling. Neither of the switches support MDIX. Which of the following types of cables should the administrator use?

Community Insight
This question tests your knowledge of Ethernet cabling standards and the critical distinction between crossover and straight-through applications based on device similarity and hardware features.
When linking two identical networking devices like switches without Auto-MDIX support, a crossover cable is required to correctly map transmit and receive pairs. Exam candidates and technical communities overwhelmingly agree that option B is the definitive solution for this N10-008 scenario.
Candidates frequently choose straight-through cables because modern switches default to Auto-MDIX, but the question explicitly removes this automation, making the physical pin-crossing mandatory.

Why the Answer Is Correct
Crossover cables physically swap the transmit and receive wire pairs, enabling direct communication between two similar devices such as switches or routers. Because both switches lack MDIX functionality, they cannot automatically detect and adjust their pin configurations, requiring a manually wired crossover cable to establish a functional link. This adheres to foundational Ethernet standards where same-type connections demand crossed wiring.Why the Other Options Are Wrong
Straight-through and standard patch cables maintain identical pinouts on both connectors, which forces transmit pins into transmit pins and receive into receive, resulting in a failed connection. Rollover cables are specifically designed for out-of-band console management access and do not carry standard Ethernet data frames. Without Auto-MDIX compensation, neither straight-through nor rollover cables will successfully negotiate a layer 2 session.Community Comment Notes
Multiple verified candidates confirmed that this exact question appeared on recent N10-008 exams in April 2024, highlighting its recurring nature. Commenters consistently reinforced the classic networking rule of thumb: crossover cables connect like devices, while straight-through cables connect unlike devices. Several high-rated notes emphasized that recognizing the explicit exclusion of MDIX is the primary trick intended by the exam writers to test foundational cabling knowledge.Official Reference
Exam Strategy
Always scan for keywords indicating device type similarity and explicitly disabled automation features like 'no Auto-MDIX' to instantly identify the required cable type. Committing the 'like equals crossover, unlike equals straight-through' mnemonic to memory will allow you to rapidly eliminate distractors and secure points on physical layer questions.
