CompTIA Server+ (SK0-004) — Question 53

A technician is troubleshooting an issue with a new server, which is unable to download OS patches from the Internet. The technician reviews the following configuration:
Ethernet Adapter Local Area Connection:
Connection-specific DNS Suffix . : comptia.org
Link-local IPv6 Address . . . . : fe80::c95:3f59:1a01:c050%11
IPv4 Address . . . . . . . . . . : 192.168.10.20
Subnet Mask . . . . . . . . . . : 255.255.255.128
Default Gateway . . . . . . . . : 192.168.10.129
Which of the following is the reason that the server is unable to connect to the Internet?

Answer options

• A. Incorrect default gateway
• B. Invalid IPv6 address
• C. Wrong subnet mask
• D. Misconfigured DNS suffix

Correct answer: A

Explanation

The server's default gateway, 192.168.10.129, is incorrect for the given subnet of 192.168.10.20, as the valid range does not include this gateway. The IPv6 address and subnet mask are correctly configured, and the DNS suffix does not impact connectivity to the Internet.
