Users are reporting collaborate.company.com is inaccessible from the user VLAN, but there is no issue connecting to the system’s web page from the DMZ. Given the following outputs from commands run on the system:
Which of the following explains why users are unable to access the system from the user VLAN, and how can the administrator remediate this issue?
A. Users cannot access the system because the IP subnet mask is /24. The remediation for this issue is to set the IP subnet mask to /16.
B. Users cannot access the system because the DNS server has the incorrect IP address. The remediation for this issue is to edit the DNS configuration to point to the correct IP.
C. Users cannot access the system because the connectivity port is running on the incorrect IP. The remediation for this issue is to edit the configuration file to listen on all interfaces.
D. Users cannot access the system because the default gateway has the wrong interface. The remediation for this issue is to set the default gateway to the proper interface.
How can answer C be correct? Obviously the ports are correct because the DMZ interface is able to connect to it just fine over ports 80 and 443, as shown in the output. This looks like a routing issue, but the default gateway assigned to enp0s3 seems correct, IF the default gateway is actually assigned the IP of 10.10.2.2, which we don’t know. I don’t really see a correct answer here.
