20+ practice questions focused on Infrastructure — one of the most tested topics on the CompTIA Tech+ (FC0-U71) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Infrastructure PracticeA network administrator is designing a new office network and wants to use a topology that provides redundancy so that if one cable fails, communication can still occur via alternate paths. Which TWO topologies offer this redundancy? (Choose TWO.)
Explanation: Mesh topology connects every device to every other device, providing multiple paths so that a single cable failure does not disrupt communication. Hybrid topology combines multiple topologies and can include redundant paths (e.g., a partial mesh component) allowing alternate routes. In contrast, star topology lacks alternate paths for the affected device, ring topology breaks entirely with a single cable fault, and bus topology also fails when the main cable is broken.
A technician is upgrading a desktop computer's memory. Which component would the technician most likely replace to improve system performance using dual-channel architecture?
Explanation: Dual-channel memory requires two identical RAM sticks installed in matching slots to increase memory bandwidth. The upgrade involves replacing or adding RAM modules.
A user wants to transfer files from a smartphone to a laptop. The smartphone supports USB-C with USB 3.0, and the laptop has both USB-A and USB-C ports. Which cable type is most appropriate for maximum transfer speed?
Explanation: USB-C to USB-C cable ensures both ends support USB 3.0 speeds. USB-A might be limited if the port is older. Direct USB-C connection avoids speed bottlenecks.
A company issues smartphones to employees and needs to enforce security policies such as remote wipe and mandatory encryption. Which technology should the IT department implement?
Explanation: Mobile Device Management (MDM) allows administrators to enforce policies, configure settings, and remotely wipe devices. It is designed for corporate device management.
A network administrator is setting up a small office network with 20 computers. The network must be easy to troubleshoot and resilient to a single cable failure affecting only one device. Which topology is most appropriate?
Explanation: Star topology connects each device to a central switch. If one cable fails, only that device is affected, making it easy to troubleshoot. It is the most common for modern networks.

Practice all Infrastructure questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Infrastructure. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Infrastructure questions on the FC0-U71 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Infrastructure is tested as part of the CompTIA Tech+ (FC0-U71) blueprint. Practicing with targeted Infrastructure questions ensures you can handle any format or difficulty that appears.
Yes. Courseiva provides free FC0-U71 practice questions across all exam topics and domains. The platform includes topic-based practice, mock exams, missed-question review, bookmarked questions, and readiness tracking — no account required.
Difficulty is subjective, but Infrastructure is a high-priority exam concept tested in multiple ways — direct recall, scenario analysis, and command-output interpretation. Consistent practice is the best way to build confidence.
