Answers to Review Questions

1. A. VLANs have many similarities and differences on wireless and wired domains. The primary difference is that VLANs do not always segment broadcast traffic into different contention domains on the wireless medium. All devices on all VLANs (for a given AP radio) share the same contention domain.

2. E. Of the five EAP types listed, only EAP-TTLS/MSCHAPv2 would meet the criteria provided. PEAPv0/EAP-MSCHAPv2 would be a common EAP type to use in this scenario, but the answer options didn’t include this EAP type. PEAPv1 always uses EAP-GTC, which employs token cards for client authentication. EAP-LEAP has known security weaknesses and is not recommended for modern networks, and EAP-TLS requires X.509 certificates for the server and clients.
