Quick Answer
The answer is a wireless access point (WAP). This device is correct because it connects to the existing ISP modem/router via an Ethernet cable, acting as a bridge that adds multiple wired ports for desktops and printers while simultaneously broadcasting a Wi-Fi signal to extend wireless coverage beyond the built-in router’s range. On the CompTIA ITF+ FC0-U61 exam, this scenario tests your understanding of how a WAP differs from a switch or a router—a common trap is confusing it with a wireless router, but a WAP does not perform routing or NAT; it simply expands both wired and wireless connectivity from an existing network. To remember this, think of the WAP as a “port multiplier and signal extender” that plugs into a router, not replaces it.
This FC0-U61 practice question tests your understanding of infrastructure. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 office uses a single ISP-provided modem/router combination device. Employees need to connect their desktops and printers to the network. Which of the following devices would allow them to connect multiple wired devices and also extend wireless coverage?
Wireless access point
A wireless access point can extend wireless coverage and often includes a built-in switch for wired connections.
Modem
Why wrong: A modem connects to the ISP and typically has only one Ethernet port.
Switch
Why wrong: A switch adds wired ports but does not provide wireless connectivity.
Hub
Why wrong: A hub does not extend wireless coverage and is not commonly used due to performance issues.

Correct answer & explanation
Wireless access point
A wireless access point (WAP) connects to the ISP modem/router via Ethernet and bridges the wired LAN to a wireless network, allowing both wired and wireless clients to communicate. In this scenario, the WAP adds additional Ethernet ports for desktops and printers while also extending Wi-Fi coverage beyond the built-in router's range.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Modem
Why it's wrong here
A modem connects to the ISP and typically has only one Ethernet port.
Switch
Why it's wrong here
A switch adds wired ports but does not provide wireless connectivity.
Hub
Why it's wrong here
A hub does not extend wireless coverage and is not commonly used due to performance issues.
Common exam traps
The trap here is that candidates confuse a wireless access point with a wireless router, but the question specifies the ISP already provides a modem/router combo, so the correct device is a standalone WAP that adds ports and Wi-Fi without routing functions.
Detailed technical explanation
A wireless access point operates at Layer 2 of the OSI model, using the 802.11 standard to manage wireless frames and often supports VLAN tagging (802.1Q) to segment traffic. In a small office, a WAP can be configured with a separate SSID and security settings (WPA3) while the ISP router handles DHCP and NAT, avoiding double NAT issues. Real-world deployment often uses Power over Ethernet (PoE) to simplify cabling by powering the WAP through the same Ethernet cable that carries data.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
