SK0-005 · Question #295
A technician is deploying a new workstation. The workstation uses DHCP and can ping other devices on the same VLAN, but it cannot access anything on a different VLAN. Which of the following steps…
The correct answer is C. Examine the DHCP scope configuration. The workstation can ping devices on the same VLAN but not on different VLANs, indicating a routing issue. The DHCP scope configuration is responsible for providing the default gateway, which is essential for inter-VLAN communication.

Why each option
The workstation can ping devices on the same VLAN but not on different VLANs, indicating a routing issue. The DHCP scope configuration is responsible for providing the default gateway, which is essential for inter-VLAN communication.
Enabling IPv6 is unlikely to resolve an IPv4 routing issue to another VLAN unless the entire network is configured for IPv6-only communication, which is not implied.
A local hosts file maps hostnames to IP addresses and is used for name resolution, not for enabling routing to different subnets or VLANs.
The inability to access devices on a different VLAN indicates that the workstation lacks a correct default gateway, which is typically provided by the DHCP server. Examining the DHCP scope configuration will verify if the default gateway is missing or incorrectly configured, preventing the workstation from routing traffic outside its local subnet.
APIPA (Automatic Private IP Addressing) is used when a DHCP server is unavailable and assigns an address in the 169.254.0.0/16 range; the workstation is already receiving a DHCP address and has local connectivity.
