300-410 Practice Question: Which TWO statements about VRF-Lite and DHCP are…
Which TWO statements about VRF-Lite and DHCP are true? (Choose TWO.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The 'ip dhcp relay' command can be configured with the 'vrf' keyword to forward DHCP requests from a VRF to a DHCP server in a different VRF.
In VRF-Lite, DHCP can be configured to operate within a specific VRF. The 'ip dhcp relay' command can be used with the 'vrf' keyword to relay DHCP requests from a VRF to a DHCP server in another VRF or the global table. Option A is correct because the relay can forward to a server in a different VRF. Option D is correct because the DHCP server can be in the global routing table and still serve clients in a VRF if the relay is configured correctly. Option B is incorrect because DHCP clients can obtain addresses from a server in the same VRF without relay. Option C is incorrect because the 'ip dhcp pool' command does not have a 'vrf' keyword; pools are global. Option E is incorrect because DHCP snooping is not required for VRF-Lite DHCP to work.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The 'ip dhcp relay' command can be configured with the 'vrf' keyword to forward DHCP requests from a VRF to a DHCP server in a different VRF.
Why this is correct
Correct. Example: 'ip dhcp relay vrf BLUE 10.1.1.1' relays requests from VRF BLUE to the DHCP server at 10.1.1.1 (which could be in another VRF or global).
- ✗
DHCP clients in a VRF cannot obtain an IP address from a DHCP server that is in the same VRF.
Why it's wrong here
Incorrect. DHCP works normally within the same VRF; the server and client can be in the same VRF without relay.
- ✗
The 'ip dhcp pool' command supports a 'vrf' keyword to associate the pool with a specific VRF.
Why it's wrong here
Incorrect. DHCP pools are global; there is no 'vrf' keyword under 'ip dhcp pool'. The VRF association is done via the relay or interface.
- ✓
A DHCP server in the global routing table can serve clients in a VRF if the relay agent is configured appropriately.
Why this is correct
Correct. The relay agent can forward requests from the VRF to the global server, and the server's response is routed back via the relay.
- ✗
DHCP snooping must be enabled globally for DHCP to work across VRFs.
Why it's wrong here
Incorrect. DHCP snooping is a security feature and is not required for DHCP operation across VRFs.
