A. B. C. D.D.
The issue mentioned in the question is that client devices are unable to enter the network because the DHCP scope is exhausted. This means that all the available IP addresses in the DHCP pool have been assigned to other devices on the network, leaving no free IP addresses for new devices to connect.
To resolve this issue without creating a new DHCP pool, the network administrator can perform the following actions:
D. Reduce the lease time: DHCP lease time is the duration for which an IP address is leased to a client device. By reducing the lease time, the IP addresses that are not in use will be returned to the DHCP pool much faster, freeing up IP addresses for new devices to connect. However, reducing the lease time may cause more DHCP traffic on the network and can also cause devices to lose their IP address and reassigning with another IP address after the lease time expires.
A. Installing load balancers: Load balancers are devices that help distribute network traffic across multiple servers to avoid overloading any one server. However, installing load balancers will not help in this situation since the issue is not related to network traffic, but rather to the exhaustion of DHCP addresses.
B. Installing more switches: Adding more switches will not help in this situation because the issue is with the DHCP pool being exhausted, which is a configuration issue, rather than a hardware issue.
C. Decrease the number of VLANs: This may help to some extent by reducing the number of IP addresses required. Still, it is not a practical solution because VLANs are used to segment networks and are necessary in many situations, and reducing the number of VLANs may cause other issues.
In conclusion, reducing the lease time is the most practical solution to the problem mentioned in the question, as it can free up IP addresses in the DHCP pool without requiring significant changes to the network configuration.
