Selected Answer: B
B. The DHCP server is offline. Explanation: The IP address 169.254.x.x is an Automatic Private IP Addressing (APIPA) address, which is assigned when a device cannot obtain an IP address from a DHCP server. APIPA addresses allow communication within the same local subnet but cannot route traffic to external networks, such as the internet. This indicates that the DHCP server is offline or unreachable.

Selected Answer: B
The correct answer is: B. The DHCP server is offline. Explanation: The IP address 169.254.10.10 is a Link-Local Address, which is automatically assigned when a device cannot obtain an IP address from a DHCP server. These addresses (ranging from 169.254.0.0 to 169.254.255.255) are part of the Automatic Private IP Addressing (APIPA) scheme and are only valid for communication within the same local subnet. Devices with APIPA addresses cannot communicate with external networks, including the internet.
