Quick Answer
The answer is star topology. This is the most efficient choice for small office file sharing because each workstation connects directly to a central switch, which provides dedicated bandwidth per connection and prevents collisions by using MAC address tables to forward data only to the intended device. On the CompTIA ITF+ FC0-U61 exam, this scenario tests your understanding of how topology affects network performance and scalability; a common trap is choosing bus topology for its low cost, but that would cause performance degradation as more devices are added and make troubleshooting much harder. The star topology also allows easy addition or removal of devices without disrupting the entire network, which is critical in a growing small office. Remember the memory tip: “Star shines alone” — each device has its own dedicated path to the center, so no single failure takes down the whole network.
This FC0-U61 practice question tests your understanding of it concepts and terminology. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A small business needs to share files among employees within the same building. Which network topology is most efficient for this scenario?
Ring
Why wrong: Ring topology is less common and a single break disables the entire network.
Bus
Why wrong: Bus topology is outdated and suffers from collision issues and single point of failure.
Mesh
Why wrong: Mesh topology is expensive and complex, typically used only for high-reliability networks.
Star
Star topology is the most common for LANs due to centralized management and easy fault detection.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Star
The star topology is most efficient for this scenario because all employee workstations connect to a central switch, which provides dedicated bandwidth per connection and simplifies troubleshooting. In a small office, the star topology allows easy addition or removal of devices without disrupting the network, and the central switch can manage traffic efficiently using MAC address tables.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Ring
Why it's wrong here
Ring topology is less common and a single break disables the entire network.
Bus
Why it's wrong here
Bus topology is outdated and suffers from collision issues and single point of failure.
Mesh
Why it's wrong here
Mesh topology is expensive and complex, typically used only for high-reliability networks.
Star
Why this is correct
Star topology is the most common for LANs due to centralized management and easy fault detection.

Common exam traps
The trap here is that candidates may confuse 'efficiency' with 'simplicity' and choose bus topology, overlooking that star topology provides better fault isolation and scalability for a shared file environment.
Detailed technical explanation
In a star topology, the central switch operates at Layer 2 of the OSI model, using MAC address learning to forward frames only to the appropriate port, which reduces collision domains compared to bus or ring topologies. Real-world implementations often use Ethernet (IEEE 802.3) with unshielded twisted-pair cabling (Cat5e or Cat6), and the switch can support VLANs to segment traffic for security or performance. The star topology also simplifies Power over Ethernet (PoE) deployment for devices like IP phones or wireless access points.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the FC0-U61 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
