Open-Ended Questions with Answers
1. What are the advantages of using DHCP over static IP
configuration?
o DHCP automates the assignment of IP addresses, reducing
manual configuration errors and administrative overhead. It
prevents IP address conflicts and allows efficient use of IP
address pools in large networks.
2. Describe the DORA process in DHCP.
o The DORA process includes:
Discovery: The client broadcasts a request for an IP
address.
Offer: The DHCP server responds with an available IP
address.
Request: The client requests to lease the offered IP.
Acknowledgment: The server confirms the lease and
provides network settings.
3. Why is it recommended to configure lease times carefully in
DHCP?
o Short lease times can cause excessive network traffic due to
frequent renewals, while long lease times can delay IP address
availability for new devices. Proper configuration ensures
optimal network performance and resource utilization.
4. What is the purpose of DHCP reservations, and how are they
configured?
o DHCP reservations provide a consistent IP address to a specific
device based on its MAC address while still using DHCP for
configuration. This is configured by linking the MAC address to
a specific IP in the DHCP server.
5. Explain the role of a scope in DHCP.
