NEW QUESTION # 116
An administrator is setting up a new site and has created a WLAN Template containing the standard corporate and guest SSIDs. This template is applied to the entire organization.
However, for this new site only, the guest network must be disabled.
What is the most efficient way to achieve this without creating a new WLAN Template?
Answer: D
NEW QUESTION # 117
Referring to the exhibit, what does the security alert indicate?
Answer: A
Explanation:
Reference: https://www.mist.com/documentation/rogue-neighbor-honeypot-aps/ According to the Security Alerts - Mist document, the security alert indicates that an AP that is not part of the Mist Org is advertising the same SSIDs as the Mist APs. This is a type of rogue AP that tries to impersonate a legitimate AP and lure users into connecting to it.

NEW QUESTION # 119
At which signal strength level range will an extra AP placed on the same channel cause co-channel contention?
Answer: C
Explanation:
In the context of Juniper Mist AI and high-performance wireless design,Co-Channel Contention (CCC)- often referred to as Co-Channel Interference (CCI)-occurs when two or more access points (APs) share the same frequency channel and are within "hearing" distance of one another.1The key to understanding this specific range lies in the802.11 CSMA/CAmechanism, specifically theClear Channel Assessment (CCA) process.
When a Mist AP or a client device wants to transmit, it first performs a CCA. If it detects a Wi-Fi preamble from another device on the same channel at a signal strength above theSignal Detect (SD)threshold (typically around -82 to -85 dBm for many radios, though performance drops much sooner), it must defer its transmission. However, for "contention" to become a significant performance bottleneck that triggers Mist SLE alerts, the signal strength usually falls within the-45 dBm to -65 dBmrange.
In this range, the signals are strong enough that the APs are effectively "in the same room" or nearby rooms, meaning they will constantly see the medium as "busy" whenever the other AP is transmitting. This effectively merges the two APs into a single contention domain, forcing them to share the total available airtime. For example, if two APs on the same channel both see each other at -60 dBm, they cannot transmit simultaneously; instead, they must take turns.
Mist'sRadio Resource Management (RRM)and theCapacity SLEspecifically monitor for these overlapping BSS (OBSS) conditions. If the AI detects that an AP is seeing a neighbor on the same channel at these high signal levels, it will attempt to change the channel or reduce transmit power to "shrink" the cell size, aiming to push the neighbor's signal strength below the point where it causes constant deferrals, thereby improving the overall capacity and user experience for the site.
NEW QUESTION # 120
You are deploying three WLAN 2.4 GHz networks in your US-based site. You must ensure that each network frequency is unique and does not overlap with the other frequency channels.
In this scenario, which three OFDM channels should be used? (Choose three.)
Answer: A,B,D
