CCNA Switching and Network Access Practice Question
A controller-based WLAN is deployed across multiple floors. Users can associate to the SSID on both floors, but their experience improves when moving between APs compared with a poorly designed standalone deployment. Which wireless concept is most closely related to that client movement experience?
⚠ Common exam trap
Be careful not to confuse network performance improvements like channel bonding with client mobility improvements like roaming.
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
✓
Roaming between access points
The concept most closely related is roaming between access points. In practical terms, client mobility experience depends on how smoothly a device can move from one AP coverage area to another while staying on the WLAN. Controller-based designs often help manage this more consistently than fragmented independent configurations. The key point is that the question is about movement between APs while remaining on the wireless network, not about VLAN trunks or routing protocol neighbors.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Roaming between access points
Why this is correct
In a controller-based WLAN spanning multiple floors, the primary user-centric issue is client mobility. When a wireless client moves from one AP's coverage to another, the controller coordinates the handoff, maintaining the client's session and IP address. This is known as roaming, and controller-based architectures support fast, secure roaming via protocols like 802.11r. Therefore, this is the correct answer.
- ✗
NetFlow export
Why it's wrong here
NetFlow export is a traffic monitoring technology that samples and exports IP flow metadata to a collector for visibility into bandwidth usage and traffic patterns. It does not influence WLAN mobility decisions, such as when a client disassociates from one AP and associates to another. Thus, NetFlow is irrelevant to the client roaming behavior described.
When this WOULD be correct
If the question asked about monitoring and analyzing traffic patterns in a network environment, particularly focusing on how data flows between devices and the impact on performance, then NetFlow export would be the correct answer.
- ✗
DHCP snooping
Why it's wrong here
DHCP snooping is a switch-level, Layer 2 security mechanism that filters DHCP server and client messages to prevent rogue DHCP servers from assigning invalid IP addresses. It operates purely on wired switch ports and has no role in wireless client movement or AP-to-AP handoff. Consequently, it is completely unrelated to the scenario of clients roaming across floors.
When this WOULD be correct
In a different scenario, a question might ask about securing a network against rogue DHCP servers in a large enterprise environment. In that context, DHCP snooping would be the correct answer as it protects clients from receiving invalid IP configurations.
- ✗
Route summarization
Why it's wrong here
Route summarization is a Layer 3 routing technique used in protocols like OSPF or EIGRP to reduce the number of prefixes advertised by combining contiguous networks. It affects routing tables and convergence but has no bearing on the Layer 2 association and reassociation process between an AP and a roaming wireless client. Therefore, it is unrelated to the wireless roaming scenario.
When this WOULD be correct
If the exam question focused on optimizing routing efficiency in a large network with multiple subnets, asking about methods to reduce routing table size or improve routing performance, then route summarization would be the correct answer.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.

When a wireless client moves from one AP's coverage to another, the controller coordinates the handoff, maintaining the client's session and IP address.

✗NetFlow exportWrong answer — click to see why▾
Why this is wrong here
NetFlow export is related to network traffic analysis and monitoring, not directly to client movement or experience between access points in a WLAN. It does not address the seamless connectivity aspect of roaming.
★ When this WOULD be the correct answer
If the question asked about monitoring and analyzing traffic patterns in a network environment, particularly focusing on how data flows between devices and the impact on performance, then NetFlow export would be the correct answer.
Why candidates choose this
Candidates may confuse NetFlow export with performance optimization concepts, thinking that monitoring traffic could somehow relate to improving user experiences during roaming between access points.
✗DHCP snoopingWrong answer — click to see why▾
Why this is wrong here
DHCP snooping is a security feature that helps prevent unauthorized DHCP servers from distributing IP addresses on a network. It does not directly relate to the user experience of roaming between access points in a WLAN deployment.
★ When this WOULD be the correct answer
In a different scenario, a question might ask about securing a network against rogue DHCP servers in a large enterprise environment. In that context, DHCP snooping would be the correct answer as it protects clients from receiving invalid IP configurations.
Why candidates choose this
Candidates may choose this option due to a misunderstanding of how DHCP functions in a network, mistakenly associating it with user connectivity and experience rather than its actual role in IP address management and security.
✗Route summarizationWrong answer — click to see why▾
Why this is wrong here
Route summarization is a technique used in routing protocols to reduce the size of routing tables by aggregating multiple routes into a single route. It does not pertain to client movement or wireless connectivity between access points.
★ When this WOULD be the correct answer
If the exam question focused on optimizing routing efficiency in a large network with multiple subnets, asking about methods to reduce routing table size or improve routing performance, then route summarization would be the correct answer.
Why candidates choose this
Candidates may confuse the concept of route summarization with the need for efficient network management, mistakenly believing it relates to improving user experience in a WLAN environment.

Routing Protocol Comparison
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
