Quick Answer
The answer is to change the default administrator password on wireless access points. This is the best practice for securing a wireless network because default credentials, such as "admin/admin," are publicly documented and easily exploited by attackers to gain full administrative control over the device. Once compromised, an attacker can alter security settings, disable encryption, or monitor traffic, making this a critical first step in network defense. On the CompTIA ITF+ FC0-U61 exam, this concept tests your understanding of basic device hardening and often appears as a distractor against options like disabling SSID broadcast or enabling MAC filtering, which are weaker security measures. A common trap is assuming that hiding the network name provides real protection, but it does not prevent an attacker from directly accessing the access point’s configuration. Remember the memory tip: "Default creds are a hacker’s best friends—change them before you hang the AP."
This FC0-U61 practice question tests your understanding of it concepts and terminology. 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.

Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Broadcast the SSID
Why wrong: Broadcasting SSID makes network visible to all; not a security best practice.
Disable MAC filtering
Why wrong: Disabling MAC filtering removes an access control layer.
Use WEP encryption
Why wrong: WEP is weak and easily cracked; use WPA2 or WPA3.
Change the default administrator password
Default passwords are well-known; changing them prevents easy access.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Change the default administrator password
Changing the default administrator password is the best practice because default credentials are widely known and easily exploited, providing an attacker with full administrative access to the wireless access point or router. This action directly mitigates unauthorized configuration changes, which is a fundamental security measure. In contrast, the other options either weaken security or have no significant protective effect.
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.
Broadcast the SSID
Why it's wrong here
Broadcasting SSID makes network visible to all; not a security best practice.
Disable MAC filtering
Why it's wrong here
Disabling MAC filtering removes an access control layer.
Use WEP encryption
Change the default administrator password
Why this is correct
Default passwords are well-known; changing them prevents easy access.
Clue confirmation

Common exam traps
The trap here is that candidates often focus on wireless-specific settings like SSID broadcast or encryption, overlooking the critical importance of securing the administrative interface itself, which is a common and easily exploited vulnerability.
Detailed technical explanation
Default administrator passwords are often set to simple strings like 'admin' or 'password' and are published in device manuals and online databases. Attackers can use automated scripts to brute-force or guess these credentials, gaining full control over the wireless network's settings, including encryption keys and firewall rules. Changing the password to a strong, unique value is a foundational step in the 'least privilege' and 'defense in depth' principles.
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.
