- A
System Settings > Network > Wi-Fi > Details > Remove this network.
This is the correct graphical method to forget a Wi-Fi network. It removes the saved password and any custom network settings, allowing a fresh connection attempt.
- B
Keychain Access and delete the Wi-Fi password entry.
Why wrong: Deleting the password from Keychain removes the stored password, but the network configuration (like security type and other settings) may remain. It is less thorough than removing the network entirely.
- C
Terminal with the 'networksetup -setairportnetwork' command.
Why wrong: This command is used to connect to a network, not to remove a saved network. It would attempt to join the network again, which may fail if the configuration is corrupted.
- D
System Information > Network > Wi-Fi.
Why wrong: System Information only displays current network status and hardware information. It does not allow modification or deletion of saved networks.
Quick Answer
The answer is System Settings > Network > Wi-Fi > Details > Remove this network. This is correct because macOS stores individual Wi-Fi network configurations, including passwords and security settings, in a per-network profile within the Network pane; deleting that profile forces the system to treat the network as new, clearing any corrupted or outdated credentials that cause authentication failures. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of macOS network troubleshooting and the distinction between configuration management (Network settings) and credential storage (Keychain Access). A common trap is assuming Keychain Access alone will fix the issue, but it only manages passwords, not the full network profile—removing the saved network from System Settings is the complete fix. Memory tip: “Network settings hold the keys to the house; Keychain just holds the key.”
220-1202 macOS Features and Tools Practice Question
This 220-1202 practice question tests your understanding of macos features and tools. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 technician is troubleshooting a Mac that fails to connect to a Wi-Fi network. The network is visible, but entering the correct password results in an 'unable to join the network' error. The technician wants to delete the saved network configuration to start fresh. Which macOS tool or location should they use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
System Settings > Network > Wi-Fi > Details > Remove this network.
The Network pane in System Settings allows you to manage network interfaces, including Wi-Fi. By selecting the Wi-Fi interface and clicking 'Advanced' or 'Details', you can see a list of preferred networks and remove the problematic one. This clears the saved password and settings. Keychain Access stores passwords but not network configurations, and Terminal is not the standard method.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
