Quick Answer
The answer is to use WPA2 encryption, disable SSID broadcast, and enable MAC address filtering. WPA2 encryption is the strongest of these because it scrambles data transmitted over the air, preventing eavesdroppers from reading your traffic even if they capture the signal. Disabling SSID broadcast hides your network name from casual scans, but it is a weak security measure since attackers can still detect the SSID using packet sniffing tools like Wireshark or airodump-ng when a client connects. On the CompTIA ITF+ FC0-U61 exam, this question tests your understanding that home wireless network security best practices prioritize encryption over obscurity, and a common trap is assuming hidden SSIDs provide robust protection. Remember the memory tip: “Encrypt first, hide second, filter third” — WPA2 is your primary shield, not invisibility.
This FC0-U61 practice question tests your understanding of security. 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.
Which three of the following are recommended practices for securing a home wireless network? (Choose three.)
Disable SSID broadcast
Hides the network from casual scans.
Update router firmware regularly
Patches security vulnerabilities.
Use WPA2 encryption
Encrypts wireless traffic.
Enable MAC address filtering
Why wrong: Provides weak security and can be bypassed.
Use the default router password
Why wrong: Default passwords are easily guessed.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Disable SSID broadcast
Disabling SSID broadcast makes the network name invisible in client scans, reducing casual discovery. However, it is a weak security measure because attackers can still detect the SSID using packet sniffing tools like Wireshark or airodump-ng when a client connects. It should be used as a minor deterrent, not a primary security control.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often think MAC address filtering is a strong security measure, but CompTIA tests the understanding that it is easily bypassed and not a recommended practice for securing a home wireless network.
Detailed technical explanation
WPA2 encryption uses AES-CCMP for data confidentiality and integrity, replacing the weaker TKIP of WPA. Regularly updating router firmware patches vulnerabilities such as buffer overflows or remote code execution flaws (e.g., CVE-2021-35394). Disabling SSID broadcast only hides the beacon frame's SSID field, but the SSID is still sent in probe requests and responses, making it trivially discoverable.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
