220-1101 Networking Practice Question
A network administrator is setting up a new wireless network in a multi-tenant office building. The administrator wants to ensure that client devices can roam seamlessly between access points without dropping connections. Which of the following should the administrator configure to allow clients to roam?
⚠ Common exam trap
The trap here is thinking that unique SSIDs help clients choose the best AP, but they actually prevent automatic 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
✓
Configure all APs with the same SSID and security settings, and place them on non-overlapping channels.
Seamless roaming requires a consistent network identity (same SSID and security) across all APs, combined with proper channel planning to avoid interference. Clients use signal strength and other metrics to decide when to roam. Unique SSIDs or same-channel configurations would disrupt roaming. MAC filtering is unrelated to roaming. The correct configuration ensures clients can move without manual intervention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure all APs with the same SSID and security settings, and place them on non-overlapping channels.
Why this is correct
For seamless roaming, all APs must broadcast the same SSID and use identical security settings (e.g., same password and encryption). Non-overlapping channels reduce interference and allow clients to switch APs based on signal strength. This configuration enables the client to maintain connectivity as it moves. Thus, this is the correct approach for roaming.
- ✗
Assign each AP a unique SSID to help clients identify the strongest signal.
Why it's wrong here
Unique SSIDs force clients to manually disconnect and reconnect to different networks, which breaks seamless roaming. Clients would not automatically switch APs unless configured to do so, and even then, it would cause interruptions. For seamless roaming, a single SSID across all APs is required. Therefore, this option is incorrect.
- ✗
Set all APs to operate on the same channel to ensure consistent connectivity.
Why it's wrong here
Using the same channel on multiple APs causes co-channel interference, which degrades performance and can prevent seamless roaming. APs should use non-overlapping channels (e.g., 1, 6, 11 on 2.4 GHz) to minimize interference. Thus, this option is incorrect.
- ✗
Enable MAC filtering on all APs to control which devices can connect.
Why it's wrong here
MAC filtering is a security measure that allows or denies devices based on MAC address. It does not facilitate roaming and can actually hinder it if not consistently configured across APs. It also adds administrative overhead. Roaming is about seamless handoff, not access control. Thus, this is not the correct configuration.

Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
