Question 1,239 of 1,389
CCNA Switching and Network Access Practice Question
A user on a wireless guest network can associate successfully, obtains an IP address, but cannot reach the Internet. Which troubleshooting area should be examined first if the WLAN itself is working?
⚠ Common exam trap
Avoid assuming issues with association or IP assignment when these steps have already succeeded.
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 post-association forwarding or policy path, such as guest routing or Internet access policy
If association and addressing are already successful, the first area to examine is the forwarding or policy path beyond simple WLAN join behavior. In practical terms, the client has passed the discovery, authentication, and addressing stages. The problem is now more likely to involve routing, gateway reachability, NAT, firewall policy, or guest-access restrictions rather than the SSID itself. This question is about understanding which stage of the workflow has already succeeded.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The post-association forwarding or policy path, such as guest routing or Internet access policy
Why this is correct
Since the client has already associated and obtained an IP address (implied by 'can associate successfully'), the failure point must be downstream of L2 association. The post-association path encompasses the WLAN-to-VLAN mapping, firewall rules, NAT, ACLs, or default gateway routing that determines guest Internet access. If any of these policy constructs is misconfigured or missing, the client will sit with a valid IP but no usable connectivity.
- ✗
The SSID broadcast name, because it must be wrong
Why it's wrong here
Because the user already associated successfully, the SSID is correct and within range; association happens at Layer 2 only after the client recognizes the SSID. An incorrect SSID would prevent association entirely, so it cannot be the cause of a problem occurring after association. Therefore, the SSID is irrelevant to the described symptom.
When this WOULD be correct
In a different scenario where a user cannot connect to the network at all, a question might ask about issues with SSID broadcasting. If the SSID is hidden or incorrectly configured, it would prevent users from associating, making this option correct.
- ✗
The AP radio antenna type only
Why it's wrong here
The antenna type affects RF coverage, signal strength, and data rates at the physical layer, but it has no bearing on post-association policy enforcement or IP-level forwarding. Once the client is associated and has an IP, the antenna has already done its job; changing antenna type wouldn't fix a routing or firewall issue. Thus, the antenna type alone cannot explain the post-association connectivity failure.
When this WOULD be correct
In a scenario where a user is unable to associate with the wireless network at all, a question could ask about troubleshooting connectivity issues related to the AP's antenna type, such as determining if the antenna is malfunctioning or improperly configured, affecting the signal strength.
- ✗
OSPFv3 area configuration on the laptop
Why it's wrong here
OSPFv3 is a routing protocol that runs between routers (or switches acting as routers) to build the routing table; a laptop as an end host typically doesn't run OSPFv3. Even if the laptop had an OSPFv3 configuration, it would not affect the guest network's forwarding of client traffic because the client uses a default gateway and does not participate in routing. This option is entirely unrelated to the guest WLAN's post-association policy.
When this WOULD be correct
If the exam question involved a scenario where a user was unable to communicate with other devices on the same subnet due to OSPFv3 misconfigurations affecting routing tables, then examining OSPFv3 area configuration would be appropriate. This would imply a more complex network setup where routing protocols directly impact connectivity.
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.

Why this is correct
Since the client has already associated and obtained an IP address (implied by 'can associate successfully'), the failure point must be downstream of L2 association. The post-association path encompasses the WLAN-to-VLAN mapping, firewall rules, NAT, ACLs, or default gateway routing that determines guest Internet access. If any of these policy constructs is misconfigured or missing, the client will sit with a valid IP but no usable connectivity.
✗The SSID broadcast name, because it must be wrongWrong answer — click to see why▾
Why this is wrong here
The SSID broadcast name is not relevant in this scenario because the user has already associated successfully and obtained an IP address, indicating that the SSID is correct and functioning.
★ When this WOULD be the correct answer
In a different scenario where a user cannot connect to the network at all, a question might ask about issues with SSID broadcasting. If the SSID is hidden or incorrectly configured, it would prevent users from associating, making this option correct.
Why candidates choose this
Candidates may mistakenly believe that if a user cannot access the Internet, the problem must be related to the network name, especially if they lack understanding of the association process and IP address assignment.
✗The AP radio antenna type onlyWrong answer — click to see why▾
Why this is wrong here
The AP radio antenna type does not directly impact a user's ability to obtain an IP address or reach the Internet after successful association. This option is irrelevant since the user is already connected to the network.
★ When this WOULD be the correct answer
In a scenario where a user is unable to associate with the wireless network at all, a question could ask about troubleshooting connectivity issues related to the AP's antenna type, such as determining if the antenna is malfunctioning or improperly configured, affecting the signal strength.
Why candidates choose this
Candidates may choose this option due to a misunderstanding of the role of antenna types in wireless connectivity, mistakenly believing that antenna configuration could affect Internet access rather than just association.
✗OSPFv3 area configuration on the laptopWrong answer — click to see why▾
Why this is wrong here
OSPFv3 area configuration is related to routing protocols and is not directly relevant to a user's inability to access the Internet on a guest network after successfully associating. The issue is likely related to network policies or forwarding paths rather than routing configurations on the user's device.
★ When this WOULD be the correct answer
If the exam question involved a scenario where a user was unable to communicate with other devices on the same subnet due to OSPFv3 misconfigurations affecting routing tables, then examining OSPFv3 area configuration would be appropriate. This would imply a more complex network setup where routing protocols directly impact connectivity.
Why candidates choose this
Candidates may choose this option due to a misunderstanding of the relationship between routing protocols and connectivity issues, especially if they have encountered OSPF-related questions in other contexts and mistakenly apply that knowledge here.

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.
