100-150 Question 140
Select 2A user reports that their Windows laptop cannot connect to the office Wi-Fi network. The SSID is visible, but the connection fails each time. As a support technician, which of the following actions should you take to troubleshoot the issue? (Choose two.)
- A
Verify that the correct SSID and password are being entered.
- B
Check if the Wi-Fi network is configured to use WPA3 encryption and ensure the laptop supports it.
- C
Run the 'ipconfig /flushdns' command to clear the DNS cache.
- D
Use the 'ping' command to test connectivity to the office router's IP address.
- E
Ensure the laptop's wireless adapter is enabled and updated to the latest drivers.
Show answer and explanation
Correct answers: A, B
Explanation
When troubleshooting Wi-Fi connection issues, it is important to verify basic settings like the SSID and password to eliminate user error. Additionally, checking encryption compatibility (e.g., WPA3) ensures the laptop can connect to the network. Other steps like DNS cache clearing or testing connectivity using ping are not directly relevant to authentication or encryption-related problems.
- A. Correct.
Verifying the SSID and password is essential to ensure the user is entering the correct network credentials. Incorrect credentials will prevent the laptop from connecting to the network.
- B. Correct.
If the Wi-Fi network uses WPA3 encryption, the laptop must support WPA3 for a successful connection. Ensuring compatibility is a critical step in troubleshooting.
- C. Incorrect.
Clearing the DNS cache with 'ipconfig /flushdns' helps resolve hostname resolution issues but is not directly relevant for troubleshooting Wi-Fi authentication failures.
- D. Incorrect.
Using 'ping' tests connectivity once connected to the network but does not help diagnose why the laptop cannot connect to the Wi-Fi in the first place.
- E. Incorrect.
While ensuring the wireless adapter is enabled and updated is a good practice, this step is not directly related to authentication or encryption compatibility issues in this scenario.
