Question 630
During a planned campus-network change at a university faculty building in Boston, operators discover that a newly segmented campus VLAN cannot obtain leases because the DHCP server is in another subnet. The design must preserve teaching tools and shared printers. What evidence should the engineer request after the repair?
Explanation
Correct Answer
This observation tests the DHCP relay and inter-subnet services requirement at a university faculty building in Boston. The expected result is that dHCP broadcasts reach the approved remote server through relay and clients receive valid leases with their intended options. The necessary correction is to configure DHCP relay on the correct routed client VLAN interface toward the authorized server and verify return-path reachability; a saved configuration alone would not prove it is working. In this case, the observed fault is that a newly segmented campus VLAN cannot obtain leases because the DHCP server is in another subnet.
Incorrect Answers
At a university faculty building in Boston, this measures a different network requirement, BGP peer state and AS compatibility. The case describes that a newly segmented campus VLAN cannot obtain leases because the DHCP server is in another subnet, so accepting this result would leave the primary fault without direct verification.
At a university faculty building in Boston, this would verify Dynamic route filtering and redistribution, not the failure reported in this scenario. The requested closure criterion instead concerns DHCP relay and inter-subnet services: dHCP broadcasts reach the approved remote server through relay and clients receive valid leases with their intended options.
At a university faculty building in Boston, this measures a different network requirement, Static/default route and route preference. The case describes that a newly segmented campus VLAN cannot obtain leases because the DHCP server is in another subnet, so accepting this result would leave the primary fault without direct verification.
