The following DHCP scope was configured for a new VLAN dedicated to a large deployment of 325 loT sensors:

The first 244 loT sensors were able to connect to the TFTP server, download the configuration file, and register to an loT management system. The other sensors are being shown as offline. Which of the following should be performed to determine the MOST likely cause of the partial deployment of the sensors?
Correct Answer: B
* The DHCP network scope defines the range of IP addresses that can be assigned to the devices on the network by the DHCP server.
* In this scenario, the DHCP scope is configured for 244 addresses, which is not enough for the 325 loT sensors that need to connect to the network.
* Therefore, the first 244 loT sensors were able to get an IP address from the DHCP server and connect to the TFTP server, while the remaining 81 sensors could not obtain an IP address and were shown as offline.
* To solve this problem, the network administrator should check the DHCP network scope and either increase the range of IP addresses or create a new scope for the additional loT sensors.
* Checking the gateway connectivity to the TFTP server, the NTP server status, or the loT devices for hardware failure are not relevant to this issue, as they would affect all the loT sensors, not just some of them. References:
