Exhibit

interface Vlan40
 ip address 10.40.40.1 255.255.255.0
 ip helper-address 10.99.99.30

Expected VLAN 40 scope: 10.40.40.0/24
Observed client address range: 10.50.50.0/24

Based on the exhibit, what is the strongest explanation for why hosts in VLAN 40 are receiving addresses from the wrong DHCP scope?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Best answer

The relay path is sending requests to the wrong DHCP scope or server target.

This is correct because the clients are receiving addresses, but from the wrong network scope.

B

Distractor review

The VLAN 40 SVI must be changed to a trunk port.

This is wrong because an SVI is not a Layer 2 switchport.

C

Distractor review

DHCP can provide only one scope in the entire network.

This is wrong because DHCP servers commonly support multiple scopes.

D

Distractor review

The clients must use static addresses before DHCP relay can work.

This is wrong because static addressing would defeat the purpose of DHCP.

Common exam trap

Common exam trap: an active trunk can still block the VLAN you need

A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.

Technical deep dive

How to think about this question

VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.

KKey Concepts to Remember

  • Access ports place end devices into a single VLAN.
  • Trunk ports carry multiple VLANs between switches.
  • Allowed VLAN lists decide which VLANs can cross a trunk.
  • Native VLAN mismatch can create confusing symptoms.

TExam Day Tips

  • Use show vlan brief to verify access VLANs.
  • Use show interfaces trunk to verify trunk state and allowed VLANs.
  • Do not treat every same-VLAN issue as a routing problem.

FAQ

Questions learners often ask

What does this 200-301 question test?

Access ports place end devices into a single VLAN.

What is the correct answer to this question?

The correct answer is: The relay path is sending requests to the wrong DHCP scope or server target. — The strongest explanation is that the DHCP relay is forwarding requests to the wrong server or service scope. In practical terms, the clients are getting addresses, which means DHCP is functioning at some level, but the addresses belong to the wrong subnet. That points away from a total DHCP failure and toward a relay target or scope-selection problem. This is a more realistic DHCP troubleshooting pattern because the service is partially working, just not correctly.
