- A
The laptops have outdated wireless drivers that do not support WPA3.
Correct. Older Windows 7 laptops typically lack WPA3 support in both drivers and OS, making them unable to authenticate with a WPA3-only network.
- B
The router's firewall is blocking the older laptops' MAC addresses.
Why wrong: Incorrect. MAC address filtering is unrelated to the security protocol; if it were the issue, it would affect all devices, not just older ones.
- C
The laptops are using an incompatible encryption cipher like TKIP.
Why wrong: Incorrect. While TKIP is outdated, WPA3 does not use it; the issue is the laptops' inability to negotiate WPA3 at all, not a cipher mismatch.
- D
The router's SSID is hidden, and the laptops cannot discover it.
Why wrong: Incorrect. A hidden SSID would affect all devices equally, not specifically older ones, and is unrelated to the security protocol upgrade.
220-1102 Wireless Security Protocols Practice Question
This 220-1202 practice question tests your understanding of wireless security protocols. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A small business owner reports that after upgrading their wireless router to a newer model, several older laptops running Windows 7 can no longer connect to the Wi-Fi network. The new router is configured to use WPA3. What is the most likely reason for the connection failures?

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The laptops have outdated wireless drivers that do not support WPA3.
WPA3 is the latest wireless security protocol, but it is not backward-compatible with older operating systems like Windows 7, which only support WPA2. The technician should configure the router to use WPA2/WPA3 mixed mode or WPA2 only to ensure compatibility with all devices.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

Got this wrong? Here's your next step.
