N10-009 Question 105
Single answer1.6 Compare and contrast network topologies, architectures, and types.A manufacturing company is opening a temporary remote job site for 40 engineers and contractors. The site has no existing cabling, must be operational within two days, and users need access to file shares, VoIP, and cloud-based project management tools. The company also wants to avoid relying on a single wireless access point because metal equipment on the site creates interference and coverage gaps. Which network design is the BEST fit for this environment?
- A
Deploy an ad hoc wireless network so client devices can connect directly to each other without centralized infrastructure
- B
Deploy a wired bus topology with all workstations sharing a single backbone cable to minimize installation time and cost
- C
Deploy an infrastructure wireless network using multiple centrally managed access points connected back to a switch
- D
Deploy a ring topology so traffic can continue circulating even if one workstation is powered off
Show answer and explanation
Correct answer: C
Explanation
The key requirement is to choose a topology and architecture that matches a temporary business site needing fast deployment, reliable access, and resilient wireless coverage. The best answer is an infrastructure wireless network with multiple centrally managed APs uplinked to a switch. In Network+ terms, this combines a wireless infrastructure architecture with a practical star-based access design on the wired side. It supports centralized authentication and management, better roaming, improved performance, and easier troubleshooting than ad hoc wireless. It also avoids outdated topologies such as bus and ring, which are not standard for modern enterprise LAN deployments. This aligns with common enterprise networking best practices and vendor design guidance from major wireless vendors, which recommend managed multi-AP infrastructure designs for business environments requiring coverage, capacity, and security.
- A. Incorrect.
Incorrect. An ad hoc wireless network is a peer-to-peer wireless arrangement in which devices communicate directly without an access point. While it can be quick for very small, temporary connections, it is not appropriate for 40 users needing reliable access to file shares, VoIP, and cloud services. It also lacks the centralized management, scalability, security controls, and roaming behavior expected in a business environment.
- B. Incorrect.
Incorrect. A bus topology uses a shared backbone cable and is largely obsolete in modern Ethernet deployments. It does not provide the reliability or performance needed for voice and business applications, and a fault or signal issue on the backbone can affect all connected devices. Modern enterprise wired networks use switched star topologies rather than bus designs.
- C. Correct.
Correct. An infrastructure wireless design with multiple access points connected to a switch is the best choice for a temporary site that needs to be deployed quickly while still supporting business applications. Multiple APs improve coverage and capacity, and centrally managed APs allow better channel planning and power adjustment to address interference from metal equipment. This is a practical example of using a wireless infrastructure architecture rather than a peer-to-peer or legacy topology.
- D. Incorrect.
Incorrect. Ring topology is not the best fit for this scenario. Traditional ring networks are uncommon in modern enterprise access networks, and they do not address the stated need for rapid deployment, wireless coverage, and support for mobile users. The option also suggests workstation participation in the ring, which is not how current business LANs are typically designed.
