The Wi-Fi Assurance SLE and classifier that would provide information about possible interference from a neighboring Wi-Fi network are Capacity and Wi-Fi Interference.

Transmissions over Wi-Fi are shared medium and half-duplex.

According to the IEEE 802.11 - Wikipedia document2, two terms that correctly describe transmissions over Wi-Fi are:

Shared medium, which means that multiple devices use the same wireless channel and have to compete for access and avoid collisions.

Half-duplex, which means that devices can either transmit or receive data at a time, but not both simultaneously.

 According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, RF templates are assigned to sites, which are logical groupings of devices based on physical location or other criteria. RF templates allow you to configure RF parameters such as channel width, transmit power, and data rates for multiple devices at once.

InJuniper Networks Mist AI Wireless, arogue access point (AP)is precisely defined to avoid confusion with external or non-threatening wireless devices. Mist qualifies a rogue AP asan unauthorized access point that is physically connected to your wired network infrastructure.

This distinction is critical from a security perspective. A rogue AP represents a direct threat because it bypasses established security controls by providing wireless access into the enterprise wired network without authorization. Such APs are often installed by users without IT approval or, in more serious cases, by malicious actors attempting to gain internal network access.

Mist APs continuously scan the RF environment and correlate wireless observations with wired-side intelligence. If an AP is detected advertising SSIDs and Mist can confirm—through MAC address correlation and wired discovery—that the device is connected to the enterprise’s wired network but isnot claimed or authorized in the Mist cloud, it is classified as a rogue AP. This allows administrators to take immediate remediation actions, such as physical removal or switch-port shutdown.

The other options are incorrect for the following reasons:

Neighbor APsare access points belonging to nearby organizations or environments and are not security threats by default. Mist classifies these separately for RF awareness.

APs close to your network as measured by RSSImay simply be physically nearby but not connected to your infrastructure; proximity alone does not make an AP rogue.

Honeypot APsare intentionally deployed decoy access points used in security research or attack detection and are not Mist’s definition of a rogue AP.

Therefore, Mist correctly defines a rogue AP asan unauthorized AP connected to your wired network, making optionAthe correct answer.

According to the Initial AP Connection and VLANs & Static IP addresses - Mist document1, when a Juniper Mist AP boots up for the first time, it will expect to see a trunked port or the native VLAN=1 and will send a DHCP request on that VLAN. The AP will attempt to connect to the Mist cloud using port 443, which is the default HTTPS port.

The AI VALIDATED status update means that the issue was opened and Marvis confirms it has been closed.

According to the Marvis Virtual Network Assistant Datasheet1, the AI-VALIDATED status update means that the issue was opened and Marvis confirms it has been closed. This status indicates that Marvis has verified that the issue is no longer present and the root cause has been resolved.

When deploying multiple Mist APs across many sites in your network and grouping similar devices together to easily apply consistent WxLAN policies across multiple sites, you should use device profiles.

In wireless networking,Adjacent Channel Interference (ACI)occurs when two or more access points transmit onpartially overlapping RF channels, causing their signals to interfere with one another. In the context ofJuniper Networks Mist AI Wireless, ACI is a critical RF condition that negatively impacts client performance and service-level expectations (SLEs).

ACI is most commonly observed in the2.4 GHz band, where only three non-overlapping channels (1, 6, and 11) are available. When access points are configured on channels such as 1 and 3, or 6 and 8, their frequency spectra overlap. This overlap results in corrupted frames, increased retransmissions, higher latency, and reduced throughput for connected clients. Unlike co-channel interference, ACI introducesuncoordinated interference, which is more damaging to overall network efficiency.

Mist AI Wireless continuously analyzes RF telemetry collected from access points and clients to identify ACI conditions. Using machine learning and RF intelligence, Mist can detect excessive retries, PHY errors, and degraded airtime efficiency associated with overlapping channels. These findings are surfaced throughMarvis AI insightsand RF-related SLE degradation indicators, allowing operators to quickly identify misconfigurations.

The incorrect options can be explained as follows:

Option Adescribes a properly designed RF environment with non-overlapping channels, which does not cause ACI.

Option Crefers toco-channel interference (CCI), where access points share the same channel and rely on contention-based access mechanisms.

Option Dis too broad; simply operating in the 2.4 GHz band does not inherently cause ACI unless overlapping channels are used.

To mitigate ACI, Mist best practices recommend usingnon-overlapping channels, minimizing channel width, and favoring the5 GHz and 6 GHz bandswhere more clean spectrum is available. Therefore, the correct description of ACI istwo or more access points operating on overlapping channels.
