  2. Step 2: Check option correctness

    network={ ssid="SecretNet" psk="safePass123" scan_ssid=1 } includes scan_ssid=1 with correct quotes around SSID and password.
  3. Final Answer:

    network={ ssid="SecretNet" psk="safePass123" scan_ssid=1 } -> Option A
  4. Quick Check:

    Hidden Wi-Fi needs scan_ssid=1 [OK]
Quick Trick: scan_ssid=1 for hidden Wi-Fi [OK]
Common Mistakes:
MISTAKES
  • Omitting scan_ssid=1 for hidden networks
