Q: 12
An engineer has performed a predictive site survey for high-speed data and voice in an indoor office.
What is the recommended data rate with -67 dBm signal level for optimal VoWLAN design?

C. That's the VoWLAN recommendation, matches standard Cisco design guides.
C tbh, that's the Cisco standard for VoWLAN at -67 dBm. 12 Mbps on 802.11an balances coverage with quality for both voice and data. Maybe B if legacy clients, but pretty confident C is what they want here.
Its C here. 12 Mbps on 802.11an lines up with Cisco VoWLAN design guides for high-speed data + voice, especially at -67 dBm. Lower rates are for legacy stuff, and 24 Mbps might cause coverage issues. I'd double-check official Cisco docs or the exam blueprint just in case, but pretty sure about this one.
C that's what Cisco recommends for VoWLAN with -67 dBm. Makes sense unless there's a specific legacy client need I'm missing.
Probably C here. For VoWLAN, the recommended minimum data rate is 12 Mbps on 802.11an with -67 dBm, since it supports both high-speed and voice and matches Cisco's best practices. A or B would keep legacy rates, but that's not ideal for modern networks. I think this is what most design guides push for, but happy to hear other takes.
D imo
Does the question specify if legacy 802.11b clients need to be supported? If so, that could change which data rates you're supposed to design around since older clients might require different minimums.
Had something like this in a mock. Cisco VoWLAN guidance points to 12 Mbps on 802.11an as the minimum with -67 dBm for both voice and high-speed data. Pretty sure C is the pick here, unless legacy requirements come up.
Be respectful. No spam.
