Designing for location-based services (LBS) requires stricter RF criteria than standard data networks. To achieve high location accuracy using Cisco Spaces, what is the recommended minimum number of APs that should hear a client device, and at what minimum RSSI threshold?
Show answer details
Correct answer: C
For accurate location triangulation/trilateration, Cisco best practices dictate that a client device must be heard by at least 3 (preferably 4) Access Points simultaneously at an RSSI of -75 dBm or better.

A network architect is selecting the access layer switches for a new deployment of Cisco Catalyst 9136 Access Points. These APs support Wi-Fi 6E and feature multiple high-performance radios. To ensure the APs operate with all radios enabled at full capabilities without power degradation, which Power over Ethernet (PoE) standard must the physical switch ports support?
Show answer details
Correct answer: A
High-end Wi-Fi 6E APs like the Catalyst 9136 require significant power due to tri-band operations (2.4, 5, and 6 GHz radios) plus additional features. To operate at full functionality without degrading radio chains or USB ports, they require 802.3bt (up to 60W/90W) or Cisco UPOE.

When determining the logical infrastructure requirements for a Cisco Catalyst 9800 Series Wireless Controller deployment, an administrator must select the appropriate software licensing tier. Which TWO of the following features strictly require a Cisco DNA Advantage license rather than a Cisco DNA Essentials license? (Select TWO)
Show answer details
Correct answer: C, D
Per the Cisco DNA Software for Wireless feature matrix, AI-Enhanced RRM (delivered through Cisco Catalyst Center and the Cisco AI Analytics Cloud) and Cisco Spaces (Spaces Extend and the optional Spaces Act, Smart Operations and Smart Venues upgrades) are included only in the Cisco DNA Advantage tier, and the DNA for Wireless data sheet lists Cisco Spaces and Cisco AI Network Analytics as components of DNA Advantage. Basic capabilities such as 802.1X authentication, guest access with a web-authentication portal and FlexConnect local switching do not require DNA Advantage; 802.1X and guest access are listed in the base tier that every subscription includes.

When calculating Link Budgets during a predictive wireless site survey, understanding material attenuation is paramount. Which of the following building materials typically introduces the highest RF signal attenuation in the 5 GHz band?
Show answer details
Correct answer: A
Solid concrete introduces significant RF attenuation, typically ranging from 12 to 15 dB at 5 GHz, making it one of the most obstructive common building materials. Drywall typically introduces 3-4 dB, and cubicle partitions introduce 1-2 dB.

An RF engineer is designing a wireless network for a university lecture hall. The hall seats 400 students. The design requirement mandates support for 2.5 devices per student, with an assumption that 40% of devices will be actively transmitting at any given time. If a single Catalyst 9136 AP radio can efficiently handle 35 active concurrent client transmissions before unacceptable airtime degradation occurs, what is the minimum number of 5 GHz radios required to support the active capacity?
Show answer details
Correct answer: C
First, calculate total devices: 400 students * 2.5 devices = 1000 devices. Next, calculate active devices: 1000 * 0.40 (40%) = 400 active devices. Finally, divide by the radio threshold: 400 / 35 = 11.42. Since you cannot have a fraction of a radio, round up to the nearest whole number, which is 12 radios.

While engineering the wireless coverage for an 80,000-seat outdoor sporting arena, the design team must mitigate severe co-channel interference (CCI) while providing high-capacity access. Which TWO of the following AP and antenna combinations, along with their deployment methodologies, are most appropriate for this ultra-high-density environment? (Select TWO)
Show answer details
Correct answer: A, C
Cisco's large-public-venue design guidance says a proper RF design with directional antennas is a must for very high density, while omnidirectional antennas (internal or external) must generally be avoided because of their large co-channel interference footprint. Overhead coverage is preferred wherever possible: narrow-beam directional (stadium) antennas on catwalks or the roof structure illuminate individual seating sections as small, well-defined cells. Where no suitable mounting locations exist, APs under the seats aimed up at the seating area are a valid but uncommon alternative: the crowd's bodies attenuate the signal and isolate each cell, allowing more APs and more capacity, although coverage differs greatly between a full and an empty venue. Low-gain dipoles in a mesh across the bleachers, or omnidirectional antennas with RxSOP disabled to maximize overlap, would increase co-channel interference.
