🧪 DHCP MCQ Quiz Hub

1. What is the purpose of the DHCP server?
to provide storage for email
to translate URLs to IP addresses
to translate IPv4 addresses to MAC addresses
to provide an IP configuration information to hosts

2. How is the message sent from a PC2 when is first powers on and attempts to contact the DHCP Server?

4. Refer to the exhibit. Which rule does the DHCP server use when there is an IP address conflict?
The address is removed from the pool until the conflict is resolved.
The address remains in the pool until the conflict is resolved.
Only the IP detected by Gratuitous ARP is removed from the pool.
Only the IP detected by Ping is removed from the pool.

5. How does a DHCP server dynamically assign IP address to host?
Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement.
Addresses are assigned for a fixed period of time. At the end of period, a new quest for an address must be made, and another address is then assigned.
Addresses are leased to host. A host will usually keep the same address by periodically contacting the DHCP sever to renew the lease.
Addresses are permanently assigned so that the host uses the same address at all times.

6. Which two tasks does the Dynamic Host Configuration Protocol perform?
Set the IP gateway to be used by the network.
Perform host discovery used DHCPDISCOVER message.
Configure IP address parameters from DHCP server to a host.
Provide an easy management of layer 3 devices.

7. Which statement is correct regarding the operation of DHCP?
A DHCP client uses a ping to detect address conflicts.
A DHCP server uses a gratuitous ARP to detect DHCP clients.
A DHCP client uses a gratuitous ARP to detect a DHCP server.
If an address conflict is detected, the address is removed from the pool and an administrator must resolve the conflict.

8. Which statements are true about the DHCP quarantine method?
The DNS server for a quarantine subnet is assigned by the enterprise DHCP server.
A quarantine subnet consists of a set of IP addresses dynamically assigned to endpoints.
Endpoint Integrity can be managed for endpoints with static IP addresses by defining exceptions.
A non-quarantine IP address is assigned by the NAC 800 after an endpoint passes integrity testing.

9. A ProCurve 3500yl switch is connected to port 1 of a ProCurve NAC 800 and a DHCP server is connected to port 2. The DHCP server IP address is 10.1.10.10/24. The NAC 800 IP address is 10.1.10.20/24. The IP address 10.1.24.1/24 is assigned to VLAN 24 on the switch. Which additional configuration settings would be appropriate for supporting a 10.1.24.0/24 non-quarantine subnet and a 10.1.25.0/24 quarantine subnet?
on the switch, a multinetted IP address of 10.1.25.1/24 assigned to VLAN 24
on the NAC 800, the IP address of the DHCP server specified as 10.1.10.10/24
on the NAC 800, IP addresses 10.1.24.51 through 10.1.24.100 defined as exceptions
on the DHCP server, one scope for 10.1.24.0/24 and a second scope for 10.1.25.0/24

10. Which configuration task is applicable to the ProCurve NAC 800 inline quarantine method?
Enable the internal firewall.
Specify one or more quarantine subnets.
Add IP address entries to the Accessible Services List.
Select the port to be used for connection to the external network.

11. What is an important factor to consider when deploying the ProCurve NAC 800 using the DHCP quarantine method?
The IP address lease duration must be set to five minutes or less on the DHCP server.
The DHCP server requires one additional, non-overlapping scope for every existing DHCP scope.
A switch must support traffic mirroring for each DHCP server protected by the NAC 800.
Endpoint Integrity cannot be enforced for devices using static IP addresses.

12. A network is configured to support a ProCurve NAC 800 operating with the DHCP quarantine method. How does an endpoint transition from a quarantine IP address to a non-quarantine IP address after passing integrity testing?
The NAC 800 triggers the switch to re-authenticate the endpoint causing a new DHCP request to be issued.
The NAC 800 sends a DHCP release to the endpoint followed by a DHCP assignment message with the IP address.
The switch stops forwarding DHCP requests from the endpoint to the NAC 800 and instead sends them to the DHCP server.
Any subsequent DHCP request from the endpoint is allowed by the NAC 800 to pass to the DHCP server.

13. A network is configured to support a ProCurve NAC 800 operating with the DHCP quarantine method. The NAC 800 is located between a ProCurve 3500yl switch and a DHCP server. How is DHCP traffic processed when an endpoint, that is currently unknown to the NAC 800, sends a DHCP request for an IP address?
The switch requests the endpoint’s integrity state from the NAC 800 before forwarding to the DHCP server.
If the NAC 800 receives a DHCP request addressed to the DHCP server, the request is blocked by the NAC 800.
The DHCP server checks the endpoint’s integrity state passed to it by the NAC 800 before responding with an IP address.
The DHCP server responds with a quarantine IP address initially and waits for the NAC 800 to indicate the endpoint has passed integrity testing.

14. A ProCurve 5406zl switch is connected to port 1 of a ProCurve NAC 800 and a DHCP server is connected to port 2 of the NAC 800. You are planning to deploy the ProCurve NAC 800 with the DHCP quarantine method using a shared subnet approach. Which configuration requirement must be satisfied?
The quarantine and non-quarantine subnets defined on the NAC 800 must be the same.
The switch requires that separate VLANs be defined for the quarantine and non-quarantine subnets.
Each switch VLAN supporting the endpoints must use a single IP helper set to the IP address of the NAC 800.
The scope on the DHCP server and the quarantine subnet on the NAC 800 must use non-overlapping IP addresses.

15. You are configuring a ProCurve NAC 800 to operate using the DHCP quarantine method. Which parameters are specified when adding a quarantine area?
IP address of the DHCP server
IP address of a RADIUS server
IP address of a default gateway
range of quarantine IP addresses
