You are asked to perform a site survey on your enterprise by using a Juniper Access Point (AP) that is fully functional and visible by the Juniper Mist cloud. Your enterprise provides you with the portable equipment for elevating the Juniper AP and a battery that properly powers it. In this scenario, how would you ensure that the Juniper AP will be fully functional for site survey purposes?
Answer : A
In a traditional deployment, a Juniper Mist Access Point is a 'cloud-first' device, meaning it expects a constant connection to the Mist Cloud to receive configuration updates and report telemetry. When performing an 'AP-on-a-Stick' (APoS) site survey, the AP is often powered by a battery pack and moved to various locations where an active Ethernet backhaul or Internet connection is unavailable.3 To ensure the AP continues to broadcast the required SSIDs for signal measurement in this 'disconnected' state, two specific settings must be adjusted within the Mist dashboard.
First, AP Config Persistence must be enabled. By default, Mist APs store their configuration in volatile memory; if an AP reboots (which happens when switching battery packs or moving locations) and cannot reach the Mist Cloud, it may fail to reload its previous configuration. Enabling Config Persistence ensures that the AP writes its current configuration to non-volatile flash memory, allowing it to boot up and start broadcasting the programmed SSIDs even in the absence of a cloud connection.4
Second, AP Uplink Monitoring must be disabled. Mist APs are designed with a safety mechanism where, if the AP loses its gateway connectivity (eth0 link or ping to the gateway), it will stop broadcasting SSIDs to prevent 'black-holing' client traffic. In a site survey scenario, the Ethernet port is typically connected only to a battery or a passive PoE injector with no data path.5 If Uplink Monitoring remains active, the AP will detect the lack of a backhaul and disable its radios, making the survey impossible. By disabling this feature, the AP is forced to keep its radios active regardless of the uplink status. Together, these two settings allow the AP to function as a standalone signal source, which is essential for accurate RF environment mapping and pre-deployment validation using Mist AI hardware.
RF templates are assigned to which Mist configuration object?
Answer : D
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.
Referring to the exhibit, what are two reasons why a Mist AP would have multiple IP addresses? (Choose two.)
Answer : B, D
According to the Mist AP43 Access Point Data Sheet document1and the Guest Access - Mist document2, two reasons why a Mist AP would have multiple IP addresses are:
The Local Status Page is enabled in the site settings, which allows the AP to have an additional IP address on VLAN 4094 for local management purposes.
A guest portal is configured on a tagged VLAN, which allows the AP to have an additional IP address on that VLAN for guest access purposes.
According to the Coverage SLE, which classifier tracks an AP that transmits at a lower data rate than a connected client?
Answer : C
According to the Virtual Network Assistant | Juniper Networks US document, Asymmetry Downlink is a classifier under the Coverage SLE that tracks an AP that transmits at a lower data rate than a connected client. This can indicate poor coverage or interference issues that affect downlink performance.
Under which hierarchy level would you create a new site configuration?
Answer : B
According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide2, you can create a new site configuration under the location hierarchy level in the Juniper Mist UI. A site is a logical grouping of devices based on physical location or other criteria.
