Refer to the exhibit. Where is the loss that is causing poor user performance?

Question

Options

• AISP edge
• Bdefault gateway
• Cdestination network
• Dwireless connection

• A
  21% (6)
• B
  64% (18)
• C
  4% (1)
• D
  11% (3)

Explanation

Option B is correct because the exhibit (typically a traceroute output) shows significant packet loss at the first hop - the default gateway - which is the router on the user's local network segment. Loss at this early hop means every packet leaving the local network is affected, directly degrading user performance for all external destinations.

Why the distractors are wrong:

• A (ISP edge): Loss further down the path (at the ISP) would appear at a later hop in the traceroute, not the first one; also, local users would still reach local resources fine.
• C (destination network): If the destination were the problem, only traffic to that specific site would suffer - not all user traffic.
• D (wireless connection): Wireless issues would show up as latency/loss before the traceroute even starts (between the device and the gateway), not as a reported hop loss in the output.

Memory tip: Think of the traceroute like a road trip - the default gateway is your driveway exit. If you can't get out of your driveway reliably, it doesn't matter how good the highway (ISP) or destination is. Loss at hop 1 = gateway problem.
