Question

A network technician enters the command ipconfig /release followed by ipconfig /renew in order to ensure that the DHCP IP configuration on a workstation is updated. However, the workstation does not receive a valid IP configuration for the network. Which two problems may exist on the network? (Choose two.)

a. There is a DHCP server issue.
b. The DHCP lease time is misconfigured.
c. The gateway router address needs to be updated.
d. There is no network connectivity to the DHCP server.
e. The ipconfig /all command must be issued to restore all IP configurations.

Answer 1

The likely problems causing the workstation not to receive a valid IP configuration could be a DHCP server issue, such as the server being down or out of IP addresses, or a lack of network connectivity to the DHCP server due to physical or configuration issues.

Step-by-step explanation:

If a network technician has used the command ipconfig /release followed by ipconfig /renew and the workstation fails to receive a valid IP configuration, this suggests a problem within the network's IP address assignment mechanism. From the options provided, two issues may be responsible for this problem:

1. There is a DHCP server issue. This could mean that the server is down, unresponsive, or that it has run out of IP addresses to allocate. Without a functioning DHCP server, the workstation cannot obtain an IP address automatically.
2. There is no network connectivity to the DHCP server. This could be due to various reasons, such as physical layer issues, incorrect switch configurations, or firewall settings blocking DHCP traffic. If there is no network path between the workstation and the DHCP server, the renewal request will not be received and thus, no IP address will be assigned.

The other options, such as the misconfiguration of the DHCP lease time or the need for an updated gateway router address, typically do not directly prevent a workstation from receiving a DHCP lease. Additionally, the ipconfig /all command is used to display all current network configuration information, but it doesn't itself restore IP configurations.
