Early in the morning, an administrator installs a new DHCP server. In the afternoon, some users report they are experiencing network outages. Which of the following is the most likely issue?

While an incorrect default gateway can lead to network connectivity issues, it would not prevent devices from obtaining an IP address from the DHCP server. Users might still be able to connect to the network but would face issues accessing external networks. Therefore, this is less likely to be the cause of the reported outages.

Insufficient routing provisions would primarily affect the ability to communicate with devices outside the local network. However, it would not directly impact the DHCP server's ability to assign IP addresses to devices. Hence, this is not the most probable issue related to the outages reported by users.

MAC addresses are unique identifiers assigned to network interfaces, and DHCP operates on IP addresses rather than MAC addresses. The number of MAC addresses available does not limit DHCP functionality, as DHCP servers do not allocate MAC addresses. Therefore, this choice does not pertain to the DHCP server's ability to assign IP addresses.
