SK0-003 · Question #773
A technician is reviewing the following configuration from a newly installed server: Network Destination Netmask Gateway Interface Metric 10.0.2.0 255.255.255.0 10.0.2.15 10.0.2.15 20 10.0.2.15 255.25
The correct answer is A. ROUTE PRINT. The default gateway is missing. The provided output, showing Network Destination, Netmask, Gateway, and Metric, indicates it's a routing table. The server is unable to communicate with the Internet because a default gateway entry is missing from this table.
Question
A technician is reviewing the following configuration from a newly installed server:
Network Destination Netmask Gateway Interface Metric 10.0.2.0 255.255.255.0 10.0.2.15 10.0.2.15 20 10.0.2.15 255.255.255.255 127.0.0.1 127.0.0.1 20 10.255.255.255 255.255.255.255 10.0.2.15 10.0.2.15 20 127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1 224.0.0.0 240.0.0.0 10.0.2.15 10.0.2.15 20 255.255.255.255 255.255.255.255 10.0.2.15 10.0.2.15 1 Which of the following commands was run to generate the above information and why is the server unable to communicate with the Internet?
Options
- AROUTE PRINT. The default gateway is missing
- BNSLOOKUP. The loopback address needs to be removed.
- CIPCONFIG. The last line in the configuration is wrong.
- DTRACERT. The interface metric is too high.

Why each option
The provided output, showing Network Destination, Netmask, Gateway, and Metric, indicates it's a routing table. The server is unable to communicate with the Internet because a default gateway entry is missing from this table.
The command `ROUTE PRINT` is used to display the IP routing table on Windows systems, which matches the format of the provided information. The absence of a default route (Network Destination 0.0.0.0, Netmask 0.0.0.0) means the server cannot forward traffic to destinations outside its local subnet, including the Internet.
`NSLOOKUP` is used for querying DNS servers and does not display routing table information.
`IPCONFIG` displays network interface configuration, not the routing table, and the last line showing broadcast information is a standard entry, not inherently wrong for internet communication issues.
`TRACERT` is used to trace the path to a destination, not to display the routing table, and while a high metric can affect route preference, the primary issue is the complete lack of a default gateway for internet access.
