A city public-works campus uses centralized DHCP servers while dual distribution switches run HSRP for access VLANs. How should DHCP relay typically be designed?
Select an answer to reveal the explanation.
Short Explanation
DHCP Discovers are shy—they broadcast on the VLAN and need a relay at the gateway to reach central servers. Put helpers on the SVI/FHRP gateway and mind which HSRP peer is active so offers still land. Standing up DHCP only on the standby is a recipe for silent leases.
Full Explanation
When DHCP servers are centralized off-subnet, IOS DHCP relay (ip helper-address) on the client gateway SVI forwards broadcasts as unicasts. With HSRP, relay should be planned so the active forwarder path consistently handles client DHCP; standby-only server tricks and missing helpers break allocation. Static addressing sidesteps DHCP but is not the asked design pattern for civic scale.
