A technician is resolving an issue where a computer is unable to connect to the Internet using a wireless access point. The computer is able to transfer files locally to other machines, but cannot…

Question

Options

• AThe computer is not using a private IP address.
• BThe gateway is not routing to a public IP address.
• CThe gateway and the computer are not on the same network.
• DThe computer is using an invalid IP address.

• A
  12% (2)
• B
  76% (13)
• C
  6% (1)
• D
  6% (1)

Explanation

Explanation

Option B is correct because while the computer and gateway are properly configured on the same local network (192.168.1.0/24), the gateway itself is failing to forward traffic beyond the local network to the public Internet - meaning the router is not translating or routing packets to a public IP address, which is required for Internet access. This explains why local file transfers work fine (same subnet communication doesn't require the gateway) but Internet access fails (which requires the gateway to route outward).

Why the distractors are wrong:

• A is incorrect because 192.168.1.x is a private IP address range (RFC 1918), so the computer is correctly using a private address
• C is incorrect because both the computer and gateway sharing the 192.168.1.0/24 subnet confirms they are on the same network
• D is incorrect because an address in the 192.168.1.x range with a /24 subnet is completely valid

Memory Tip

Think of it this way: local = same street, Internet = leaving the neighborhood. If your car works fine driving around the block (local transfers) but can't get on the highway (Internet), the problem is the on-ramp (gateway), not your car. The gateway's job is to bridge private → public, and here it's failing to do so.
