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?

1.The NAC 800 triggers the switch to re-authenticate the endpoint causing a new DHCP request to be issued.

2.The NAC 800 sends a DHCP release to the endpoint followed by a DHCP assignment message with the IP address.

3.The switch stops forwarding DHCP requests from the endpoint to the NAC 800 and instead sends them to the DHCP server.

4.Any subsequent DHCP request from the endpoint is allowed by the NAC 800 to pass to the DHCP server.

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?

1.The switch requests the endpoint’s integrity state from the NAC 800 before forwarding to the DHCP server.

2.If the NAC 800 receives a DHCP request addressed to the DHCP server, the request is blocked by the NAC 800.

3. The DHCP server checks the endpoint’s integrity state passed to it by the NAC 800 before responding with an IP address.

4. The DHCP server responds with a quarantine IP address initially and waits for the NAC 800 to indicate the endpoint has passed integrity testing.

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 The NAC 800 IP address is The IP address is assigned to VLAN 24 on the switch.
Which additional configuration settings would be appropriate for supporting a non-quarantine subnet and a quarantine subnet?

1.on the switch, a multinetted IP address of assigned to VLAN 24

2.on the NAC 800, the IP address of the DHCP server specified as

3.on the NAC 800, IP addresses through defined as exceptions

4. on the DHCP server, one scope for and a second scope for

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?

1. The quarantine and non-quarantine subnets defined on the NAC 800 must be the same.

2.The switch requires that separate VLANs be defined for the quarantine and non-quarantine subnets.

3.Each switch VLAN supporting the endpoints must use a single IP helper set to the IP address of the NAC 800.

4.The scope on the DHCP server and the quarantine subnet on the NAC 800 must use non-overlapping IP addresses.

3.all of the above

4. All of the mentioned

How does a DHCP server dynamically assign IP address to host?

1.Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement.

2.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.

3.Addresses are leased to host. A host will usually keep the same address by periodically contacting the DHCP sever to renew the lease.

4.Addresses are permanently assigned so that the host uses the same address at all times.

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

1.Layer 3 unicast

2.Layer 3 broadcast
