You are troubleshooting an issue with no connectivity through a DSL modem. Which of the following is a first step in resolving an issue?
  1. Power cycling the modem
  2. Identify the LEDs on the modem
  3. Using ipconfig to renew all IP parameters
  4. Term the modem as faulty and replace it with a working one
Explanation
Answer: B - The first thing to check for is the LEDs on the modem. This should give you direction for how best to proceed with the fix and which component to check for errors.

Key Takeaway: A typical modem has 4 attributes: power, DSL, LAN and Internet. These are represented by 4 LEDs on the modem. Assuming that the LEDs are functioning properly, one may get something to work on once the LED status is known. For example, if the DSL LED is OFF, then try to call the DSL provider for no connectivity issues.
