- A
Install multiple thick access points with overlapping channels.
Why wrong: Thick APs operate independently, so roaming may cause disconnections. Overlapping channels can cause interference, not seamless roaming.
- B
Use a single high-power access point in the center of the building.
Why wrong: A single AP cannot provide adequate coverage through concrete floors and metal studs. Users on different floors would have poor signals.
- C
Deploy thin access points connected to a wireless LAN controller.
Correct. Thin APs are managed by a controller that handles roaming, load balancing, and channel selection, ensuring seamless connectivity as users move.
- D
Use mesh access points with wireless backhaul.
Why wrong: Mesh APs can extend coverage, but wireless backhaul through concrete and metal is inefficient and can cause latency. Wired backhaul is preferred for seamless roaming.
Quick Answer
The answer is to deploy thin access points connected to a wireless LAN controller. This configuration supports seamless wireless roaming because the controller centralizes management and coordinates fast handoffs between APs, allowing a user’s session to transfer instantly as they move between floors without re-authenticating. On the CompTIA A+ Core 1 220-1201 exam, this question tests your understanding of wireless deployment architectures, specifically the difference between autonomous (thick) and controller-based (thin) APs. A common trap is assuming that more powerful standalone APs solve coverage gaps, but in environments with concrete floors and metal studs, only thin APs with a controller can handle the rapid, coordinated transitions required for true roaming. Remember the mnemonic: “Thin APs need a brain—the controller handles the pain.”
220-1101 Common Networking Hardware Practice Question
This 220-1201 practice question tests your understanding of common networking hardware. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 network administrator is deploying a new wireless network in a large office building. They need to ensure seamless roaming for users moving between floors. The building has concrete floors and metal studs. Which hardware configuration will best support this requirement?

Correct answer & explanation
Deploy thin access points connected to a wireless LAN controller.
This question tests advanced knowledge of wireless deployment and roaming. Thin access points with a wireless controller allow centralized management and fast roaming, as the controller coordinates handoffs between APs. Thick APs or standalone units do not support seamless roaming as effectively.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

- ✗
Install multiple thick access points with overlapping channels.
Why it's wrong here
Thick APs operate independently, so roaming may cause disconnections. Overlapping channels can cause interference, not seamless roaming.
- ✗
Use a single high-power access point in the center of the building.
Why it's wrong here
A single AP cannot provide adequate coverage through concrete floors and metal studs. Users on different floors would have poor signals.
- ✓
Deploy thin access points connected to a wireless LAN controller.
Why this is correct
Correct. Thin APs are managed by a controller that handles roaming, load balancing, and channel selection, ensuring seamless connectivity as users move.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.

Why it's wrong here
Mesh APs can extend coverage, but wireless backhaul through concrete and metal is inefficient and can cause latency. Wired backhaul is preferred for seamless roaming.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
