FC0-U71 Practice Question: Refer to the exhibit

Exhibit

Refer to the exhibit.

ipconfig

Windows IP Configuration

Ethernet adapter Local Area Connection:
   Connection-specific DNS Suffix  . : example.com
   IPv4 Address. . . . . . . . . . . : 192.168.1.101
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.1.1

Refer to the exhibit. A user reports that they cannot access the internet. Based on the output, which of the following is the MOST likely issue?

⚠ Common exam trap

The FC0-U61 exam often tests the distinction between local connectivity (IP/subnet valid) and gateway reachability; the trap here is that candidates see a valid IP and subnet and assume the problem is DNS-related, ignoring the failed ping to the default gateway.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The router at 192.168.1.1 is down

The default gateway 192.168.1.1 is unreachable, as shown by the 100% packet loss in the ping output. Without a functional gateway, traffic cannot be routed from the local subnet to external networks, so internet access fails even if the local IP configuration is valid.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The router at 192.168.1.1 is down

    Why this is correct

    Default gateway unreachable would cause no internet.

  • The subnet mask is incorrect

    Why it's wrong here

    255.255.255.0 is correct for /24.

  • The IP address is invalid

    Why it's wrong here

    192.168.1.101 is valid private IP.

  • The DNS suffix is missing

    Why it's wrong here

    DNS suffix is not required for internet access.

Visual reference

192.168.1.0 /24 256 addresses (254 usable) 192.168.1.0 /25 Subnet A 128 addr (126 usable) 192.168.1.128 /25 Subnet B 128 addr (126 usable) Borrowing 1 bit from host portion creates 2 subnets (/25)
