Exam 300-420 topic 1 question 310 discussion

Actual exam question from Cisco's 300-420

Question #: 310
Topic #: 1

A customer plans to deploy WoL in the enterprise with these high-level design requirements:

• DHCP services must be available
• Clients BIOS settings must be set for WoL
• Clients get IP addresses once online
• Spanning-tree PortFast is enabled on the Layer 2 switches

Which two solutions must the customer select to have a successful deployment? (Choose two.)

A. IP directed broadcast and forward-protocol must be enabled on all the SVI or routed interfaces where the client subnets reside
B. IP directed broadcast and forward-protocol must be disabled on all the SVI or routed interfaces where the client subnets reside
C. IP helper-addresses for the client ranges must be disabled on the SVI or routed interface where the WoL server subnet resides
D. IP helper-addresses for the WoL server must be enabled on the SVI or routed interface where the client subnets reside
E. IP helper-addresses for the client ranges must be enabled on the SVI or routed interface where the WoL server subnet resides

D would be correct only if the WOL server is the DHCP server. You have to configure helper on the WOL server router interface that will allow the WOL server to reach the subnet of the WOL client. Normally, ClientSubnet.255 for all WOL subnets. So...option E in this case.

You’re correct. D would be necessary only if the WoL server is handling DHCP services, as this would allow the DHCP server (or WoL server) to reach client subnets. However, for standard WoL implementations where the broadcast needs to be forwarded to clients, A and E are essential. • A ensures that IP directed broadcasts can reach client subnets, which is needed for sending WoL packets across networks. • E is crucial for directing the traffic correctly if there’s a helper address needed on the interface where the clients are located. Your understanding aligns well with practical deployment scenarios.
