NEW QUESTION # 31
Using the rule of 10s and 3s, how many mW does 23 dBm convert to?
- A. 250 mW
- B. 200 mW
- C. 225 mW
- D. 150 mW
Answer: B
Explanation:
TheRule of 10s and 3sis a quick mental calculation used to convert betweendBm (decibel-milliwatts)and milliwatts (mW), which represent power levels. The rule states that:
* Every10 dB increasecorresponds to a10× increase in power.
* Every3 dB increasecorresponds to approximately a2× increase in power.
Starting from0 dBm = 1 mW:
* +10 dBm = 10 mW
* +20 dBm = 100 mW
* Add 3 dB # 23 dBm = 100 mW × 2 #200 mW
Thus,23 dBm converts to approximately 200 mW. This principle is used throughout RUCKUS documentation for understandingEIRP (Effective Isotropic Radiated Power)and ensuring compliance with regulatory transmit power limits.
According toRUCKUS One Online HelpandRUCKUS AI user documentation, administrators often use this conversion when optimizing transmit power settings to balance coverage and interference. The rule helps design engineers translate dB settings into physical power outputs during Wi-Fi tuning and planning.

NEW QUESTION # 39
Which type of interference occurs when two APs are configured on channel 7 and channel 8 in the same physical space?
- A. Multipath
- B. Adjacent
- C. Diffraction
- D. Co-channel
Answer: B
Explanation:
When two access points operate on overlapping channels in the same frequency band-such as channel 7 and channel 8 in the 2.4 GHz range-they create Adjacent Channel Interference (ACI). Unlike co-channel interference (CCI), which occurs when APs share the exact same channel, ACI results from partial channel overlap that causes energy spillover between adjacent frequencies.
According to RUCKUS One Online Help - Radio Configuration and Channel Planning, adjacent channels in 2.4 GHz are only 5 MHz apart, while each Wi-Fi channel occupies 20-22 MHz of bandwidth. As a result, channels like 7 and 8 significantly overlap, creating degraded performance, retransmissions, and reduced throughput.
RUCKUS's ChannelFly technology in both RUCKUS AI and RUCKUS Analytics helps automatically select non-overlapping channels (such as 1, 6, and 11) to minimize ACI and optimize network capacity.
Therefore, the correct answer is A - Adjacent interference, which directly applies to overlapping channel configurations.

NEW QUESTION # 40
Client connections in a RUCKUS outdoor deployment are unstable at the outer edge. These client signals are not strong enough to properly communicate to the AP.
What action will resolve this issue?
- A. Enable RTS/CTS mechanisms
- B. Change client polarity to match AP
- C. Increase outdoor AP power
- D. Implement antennas with increased gain
Answer: D
Explanation:
Weak client connectivity at the edge of coverage is typically caused by insufficient received signal strength rather than AP transmit power limitations. Increasing AP power does not help if the client device cannot transmit back effectively.
According to RUCKUS One Online Help - Outdoor RF Design and Antenna Optimization, the best corrective action is to use higher-gain directional or sector antennas (D), which focus RF energy toward client areas to improve link budget and two-way communication.
RUCKUS Analytics 3.5 User Guide - RF Link Quality Metrics confirms that directional gain antennas improve downlink and uplink SNR, enhancing stability without increasing interference footprint.
RTS/CTS helps mitigate collisions, and polarity alignment applies to point-to-point backhaul, not client coverage.

Which capability within Client Isolation will allow clients to access specific destinations within the same subnet?
- A. Access control list
- B. Directed multicast
- C. Gateway access list
- D. Isolation whitelist
Answer: D
Explanation:
TheClient Isolationfeature on RUCKUS access points and controllers prevents wireless clients connected to the same SSID from communicating directly with each other within the same subnet. This is particularly important for guest or public networks to enhance security and privacy. However, administrators may sometimes need to allow access to specific network services or devices-such as printers, gateways, or media servers-within that same subnet.
RUCKUS systems address this need through theIsolation Whitelistcapability. As described in theRUCKUS One Online HelpandRUCKUS Cloud documentation, theIsolation Whitelistallows administrators to specify destination IP or MAC addresses that are exempt from client isolation rules. This enables controlled access without fully disabling client isolation across the network.

By which process does 802.11k assist in client roaming?
- A. Ignoring join requests for weak clients
- B. Caching encryption information
- C. Providing a list of available neighbor APs
- D. Forcing clients to disconnect from their associated AP
Answer: C
Explanation:
TheIEEE 802.11kamendment enhances Wi-Fi client roaming by allowing an AP to share information about nearby access points with connected clients. This process, known as theNeighbor Report, provides alist of available APsthat the client can use to make faster, more informed roaming decisions.
When a client device receives this neighbor list, it canscan fewer channels, reducing latency and improving the handoff experience-especially in enterprise networks managed byRUCKUS One,SmartZone, or RUCKUS Cloud. According toRUCKUS One Online HelpandRUCKUS AI documentation, enabling
802.11k/v/rfeatures together allows forfast and seamless roaming, as 802.11k supplies discovery data,
802.11v assists with steering decisions, and 802.11r enables fast re-authentication.
OptionCis correct because 802.11k's core function is to help clients identify the best potential APs to roam to.
The other options describe unrelated functions: encryption caching relates to 802.11r, ignoring weak clients is an AP policy function, and forcing disconnections occurs during load balancing or steering-not through
802.11k.
