A transmitted RF signal reaching the receiver over multiple paths because of reflections and other propagation effects<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Multipath occurs when transmitted RF energy reaches a receiver over several paths because signals reflect, scatter, or diffract from walls, furniture, metal surfaces, and other objects. The different copies can arrive with different delays and phases. Depending on the wireless technology and environment, multipath can either degrade reception or be exploited by modern MIMO techniques. Multipath is an RF propagation phenomenon rather than an IP-routing or authentication function. Understanding it is useful when evaluating signal quality, AP placement, antenna behavior, and why clients can experience different performance even when measured RSSI appears similar.<\/span><\/p>\n<p><b>Q162. What is the PRIMARY concern when two directional antennas intended to communicate with each other have incompatible polarization?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Significant signal loss can occur because the antennas do not efficiently receive each other&#8217;s polarized energy<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> DHCP automatically fails<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The SSID becomes hidden<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The AP changes its Mist Site automatically<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. Significant signal loss can occur because the antennas do not efficiently receive each other&#8217;s polarized energy<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Antenna polarization describes the orientation of the electromagnetic field radiated by the antenna. When transmitting and receiving antennas have significant polarization mismatch, the receiving antenna captures less of the transmitted energy, reducing effective signal strength. This can degrade link quality even when other RF parameters appear reasonable. Polarization is particularly important when working with directional or externally mounted antennas. It has no direct relationship to DHCP, SSID visibility, or Mist Site assignment. Correct antenna orientation should therefore be part of physical WLAN deployment validation and troubleshooting.<\/span><\/p>\n<p><b>Q163. What does EIRP describe in a wireless system?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> The effective radiated power after considering transmitter power and antenna gain<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The number of clients associated with an AP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The size of the DHCP scope<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The number of SLE classifiers configured<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. The effective radiated power after considering transmitter power and antenna gain<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">EIRP, or Effective Isotropic Radiated Power, represents the effective transmitted RF power after considering factors such as transmitter output and antenna gain, along with relevant losses. Regulatory limits often apply to radiated power rather than simply the configured radio transmit value. This is important when using antennas with different gain characteristics. EIRP does not indicate client count, address-pool size, or SLE configuration. WLAN designers must understand transmit power, antenna gain, and local regulatory requirements so that deployments achieve appropriate coverage without exceeding permitted RF limits.<\/span><\/p>\n<p><b>Q164. What is one potential disadvantage of using an 80 MHz channel instead of a 20 MHz channel in a dense WLAN?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> The AP stops supporting encryption<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The client cannot roam<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Fewer non-overlapping channel choices remain available for reuse<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Mist cloud management is disabled<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. Fewer non-overlapping channel choices remain available for reuse<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Channel bonding can increase potential PHY throughput by combining more spectrum into one wider channel. However, a wider channel consumes more of the available RF spectrum, leaving fewer independent channels for neighboring APs. In dense deployments this can increase co-channel contention and reduce the efficiency of channel reuse. For that reason, narrower channels are often preferred where client density and AP density matter more than maximum single-client throughput. Channel width does not disable security, roaming, or Mist management. Good WLAN design balances throughput, capacity, spectrum availability, and interference.<\/span><\/p>\n<p><b>Q165. What is the purpose of the random backoff process used by 802.11 stations?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> To assign a random VLAN<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To disable retries<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To select a random RADIUS server<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To reduce the chance that multiple stations transmit at the same instant after the medium becomes available<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. To reduce the chance that multiple stations transmit at the same instant after the medium becomes available<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">When several Wi-Fi stations are waiting for the same busy channel, they could all begin transmitting immediately when it becomes idle. The randomized backoff mechanism reduces that risk by having each station wait for a randomly selected number of contention slots before transmitting. If the medium becomes busy again, the backoff process pauses and later resumes. This is a core part of CSMA\/CA operation. It has nothing to do with VLAN assignment or RADIUS server selection. Backoff behavior helps explain why contention increases latency as more active devices share one RF channel.<\/span><\/p>\n<p><b>Q166. What is the purpose of a reassociation frame during client roaming?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> It supports the client&#8217;s transition from one AP to another within the WLAN<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It renews the client&#8217;s PoE allocation<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It updates the Mist subscription<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It creates a new DHCP server<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. It supports the client&#8217;s transition from one AP to another within the WLAN<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Reassociation is part of the 802.11 roaming process. When a client moves from one AP to another in the same extended wireless network, it can use reassociation mechanisms to establish the new AP relationship while indicating that it was previously associated elsewhere. The exact roaming behavior depends on client implementation and WLAN security features. Reassociation is a Layer 2 wireless management process rather than a power, licensing, or DHCP function. Understanding association and reassociation helps administrators distinguish Wi-Fi roaming failures from authentication, addressing, or application-layer problems.<\/span><\/p>\n<p><b>Q167. Why are Preferred Scanning Channels useful for compatible 6 GHz clients?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> They force every client onto the same AP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> They disable active scanning entirely<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> They help clients discover 6 GHz WLANs more efficiently by focusing scanning on designated channels<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> They assign IP addresses before association<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. They help clients discover 6 GHz WLANs more efficiently by focusing scanning on designated channels<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The 6 GHz band contains many channels, so blindly scanning every possible channel can add discovery delay and consume additional client power. Preferred Scanning Channels provide a more efficient discovery strategy by directing compatible clients toward selected channels where 6 GHz WLAN information is expected. This improves scan efficiency without replacing association or authentication. PSCs do not assign IP addresses or force all devices to one AP. As newer WLAN deployments increasingly use 6 GHz, efficient discovery mechanisms become important to client connection and roaming behavior.<\/span><\/p>\n<p><b>Q168. A Mist administrator needs to allow a help-desk user to troubleshoot clients but not modify WLAN configuration. What is the BEST approach?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Assign an appropriate Mist account role with only the required operational privileges<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Share a full administrator account<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Give the user every organization permission<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Disable authentication for the Mist portal<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. Assign an appropriate Mist account role with only the required operational privileges<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Mist account roles should follow least-privilege principles. A help-desk user who only needs visibility into clients, events, and troubleshooting information should not receive broad configuration authority if that is unnecessary for the job. Proper role assignment reduces the risk of accidental changes while still enabling effective support. Shared administrator credentials weaken accountability and should be avoided. Mist&#8217;s organization and account model supports differentiated administrative access, which is important in larger operational teams where network engineering, help desk, security, and auditing responsibilities may be separated.<\/span><\/p>\n<p><b>Q169. An administrator has physically installed a new Mist AP and added it to inventory but has not assigned it to a Site. What is the MAIN consequence?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> The AP cannot receive any PoE<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It may not receive the intended Site-specific WLAN and operational configuration<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Its Ethernet MAC address changes<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It automatically becomes a Mist Edge<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. It may not receive the intended Site-specific WLAN and operational configuration<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A Site provides location-specific configuration and operational context in Mist. If an AP is part of the organization but not assigned to the correct Site, it may not inherit the WLANs, RF settings, maps, policies, and other configuration expected for that physical location. Inventory ownership and Site assignment are therefore separate considerations. Site assignment does not determine whether the switch provides PoE, and it does not change the AP&#8217;s hardware identity. Correct Site placement is also important for troubleshooting, reporting, and location-based services.<\/span><\/p>\n<p><b>Q170. Why should automation scripts using the Mist REST API use narrowly scoped credentials where possible?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> To reduce the impact if the automation credential is compromised or the script contains an error<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To increase AP radio transmit power<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To improve Bluetooth accuracy<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> To remove the need for HTTPS<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. To reduce the impact if the automation credential is compromised or the script contains an error<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Automation can make changes quickly and across large numbers of objects, so excessive API privileges create significant risk. A script should receive only the access required for its intended task. If an API token or credential is stolen, limited privileges constrain what an attacker can do. Narrow scope also reduces the damage caused by coding mistakes. API authentication should remain protected by secure transport and normal access controls. Credential scope has no relationship to RF power or Bluetooth calculations. Mist automation should combine least privilege, secure secret handling, testing, and logging.<\/span><\/p>\n<p><b>Q171. What is a key difference between locally bridged WLAN traffic and traffic tunneled to Mist Edge?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Locally bridged traffic enters the wired network near the AP, while tunneled traffic is carried to the Mist Edge termination point<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Locally bridged traffic does not use 802.11<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Tunneled traffic does not require authentication<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Mist Edge traffic cannot use IP addresses<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. Locally bridged traffic enters the wired network near the AP, while tunneled traffic is carried to the Mist Edge termination point<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">In a locally bridged WLAN, client traffic is generally placed onto the local wired network at or near the AP according to the WLAN&#8217;s VLAN design. In a tunneled architecture, client traffic is encapsulated and transported toward Mist Edge before entering the appropriate network path. These models can produce very different DHCP, routing, firewall, and troubleshooting behavior. Both still rely on 802.11 for wireless access and can use normal authentication and IP addressing. Understanding the data path is essential when clients connect successfully but cannot reach downstream network services.<\/span><\/p>\n<p><b>Q172. A client joins an MPSK WLAN using the wrong valid key and receives access intended for a different device group. What should be investigated?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> AP PoE negotiation<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The MPSK mapping and associated policy\/VLAN assignment<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Floor-plan calibration<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> DFS radar history only<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. The MPSK mapping and associated policy\/VLAN assignment<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Multiple PSK can associate different keys with different policy outcomes. If a client uses a valid key but lands in the wrong access segment, the problem may be in the mapping between that key and its assigned role, VLAN, or policy. Administrators should verify which key the client actually used and how that key is configured in the WLAN policy. AP power and floor-plan settings do not determine MPSK authorization. This illustrates the difference between successful authentication and correct post-authentication policy assignment.<\/span><\/p>\n<p><b>Q173. What is the MAIN purpose of Wireless Intrusion Prevention in addition to wireless intrusion detection?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> It can provide mitigation capabilities against selected wireless threats where supported and appropriately configured<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It assigns DHCP leases<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It replaces all firewall rules<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> It increases WLAN throughput automatically<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. It can provide mitigation capabilities against selected wireless threats where supported and appropriately configured<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Wireless intrusion detection focuses on identifying suspicious RF activity, while prevention adds the possibility of taking supported mitigation actions against certain detected threats. Because wireless prevention techniques can affect devices over the air, administrators should configure them carefully and understand regulatory and operational implications. WIPS does not assign addresses, replace firewalls, or inherently improve throughput. It should complement strong WLAN authentication, encryption, wired security, and monitoring. Juniper includes wireless intrusion detection and prevention among the current JN0-452 WLAN concepts.<\/span><\/p>\n<p><b>Q174. A Mist alert is repeatedly generated for a known maintenance condition that does not require action.

Review the alert configuration and tune it appropriately without hiding unrelated meaningful events<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Operational alerts are useful only when administrators can distinguish meaningful conditions from expected noise. If a known maintenance activity repeatedly generates an alert that requires no response, the team should review thresholds, scope, scheduling, or other available alert settings. The goal is to reduce unnecessary noise without masking genuine failures. Disabling all alerts would make important issues easier to miss, while deleting network objects would not solve alert quality. Effective network operations require regular tuning so notifications remain actionable and aligned with real support priorities.<\/span><\/p>\n<p><b>Q175. Why can an SLE remain degraded even after the original underlying problem has been corrected?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> SLE calculations can include data from an evaluation window that still contains earlier failures<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> SLEs can never improve once degraded<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The AP must always be rebooted<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The Site must be deleted and recreated<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. SLE calculations can include data from an evaluation window that still contains earlier failures<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An SLE often represents experience measured over a defined time range rather than only the most recent instant. If a DHCP, coverage, or authentication problem affected users earlier in that window, the aggregate SLE can remain below its target for some time after the network has been corrected. Administrators should therefore consider the selected time period and review recent events to verify whether failures are still occurring. A lingering historical impact does not necessarily mean the remediation failed. SLE interpretation should combine current telemetry with awareness of the measurement window.<\/span><\/p>\n<p><b>Q176. An administrator sees poor SLE performance only for one device model across several APs and Sites.

A client-specific driver, firmware, roaming, or compatibility issue<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">When failures follow one client model across multiple APs and Sites, the common factor is the client rather than a single infrastructure device. Administrators should compare driver versions, firmware, supported security features, roaming behavior, band capabilities, and known compatibility issues. Mist client insights can help reveal whether the devices fail at the same stage of connection or exhibit the same RF behavior. Infrastructure should still be validated, but replacing all APs or assuming a cloud outage ignores the strongest pattern in the evidence.<\/span><\/p>\n<p><b>Q177. Marvis identifies a high number of authentication failures for one WLAN.

Review authentication events, affected client identities, RADIUS responses, and recent configuration changes<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Marvis can quickly identify that authentication is a likely failure domain, but administrators should then inspect the underlying evidence. RADIUS response codes, certificate problems, identity-store reachability, client types, policy changes, and timing can explain why authentication failures increased. AP replacement or RF-power changes are unlikely to solve a backend identity issue when association is otherwise succeeding. Marvis is most effective when AI-driven insights direct the administrator toward the right evidence and reduce the time spent investigating unrelated parts of the WLAN.<\/span><\/p>\n<p><b>Q178.

Synthetic checks can provide service evidence even when real-client activity is low, complementing actual user telemetry<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Real-client telemetry reflects actual user experience, but there may be times when a branch or office has few active clients. Marvis Minis can provide additional synthetic service validation during those quiet periods. Together, synthetic checks and actual SLE data give operations teams a more continuous picture of network health. Minis do not replace real users or make SLEs unnecessary; they complement them. This supports proactive assurance by helping detect issues before employees arrive or before sufficient user activity exists to reveal a widespread problem.<\/span><\/p>\n<p><b>Q179.

Location calculations still assume the AP remains at its old mapped coordinates<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Location services depend on accurate knowledge of where the RF and Bluetooth infrastructure is physically installed. If an AP is moved but its map position is not updated, the system continues interpreting wireless observations using the old location as a reference. This can shift calculated client or asset positions and reduce overall location accuracy. AP placement and floor-plan scale are therefore operational data that must remain synchronized with the real environment. Moving an AP does not inherently alter subscriptions, WLAN security, or DHCP behavior.<\/span><\/p>\n<p><b>Q180.
