JN0-452 Exam Dumps - Juniper JNCIS-MistAI Questions and Answers

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide2, a device profile is a configuration object that allows you to group similar devices together and apply consistent WxLAN policies across multiple sites. A device profile defines parameters such as device type, OS, and MAC address.

Mist Radio Resource Management (RRM) performs several functions including transmit power control and channel assignment which help optimize wireless network performance by dynamically adjusting radio settings based on changing environmental conditions.So,the correct answers are A.transmit power control and C.channel assignment

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, two functions of Mist Radio Resource Management (RRM) are:

Transmit power control, which adjusts the transmit power of APs based on their coverage area and interference level.

Channel assignment, which assigns channels to APs based on their location and interference level.

InJuniper Networks Mist AI Wireless, understanding modulation schemes is essential for designing and operating high-performance Wi-Fi 6 (802.11ax) networks. Modulation directly affects how much data can be transmitted per symbol, and therefore determines the maximum achievable data rates under optimal RF conditions.

802.11ax introduces 1024-QAM (Quadrature Amplitude Modulation)as its highest supported modulation scheme. With 1024-QAM, each symbol encodes10 bits of data, which represents a significant increase compared to earlier standards. For reference:

64-QAM (used in earlier standards) carries 6 bits per symbol

256-QAM (introduced in 802.11ac) carries 8 bits per symbol

1024-QAM increases this to 10 bits per symbol

This higher bit density allows Wi-Fi 6 devices to achievehigher peak throughput, especially in environments with excellent signal quality. However, 1024-QAM requiresvery high Signal-to-Noise Ratio (SNR)and low interference to function reliably. As a result, it is typically achieved only when clients are close to the access point and RF conditions are clean.

Mist AI Wireless continuously monitors client RSSI, SNR, retransmissions, and modulation rates through advanced telemetry. Using this data, Mist can determine whether clients are successfully operating at higher modulation levels like 1024-QAM or are falling back to lower schemes due to RF impairments. This insight directly feeds into SLEs and AI-driven recommendations for RF tuning, AP placement, and channel planning.

The incorrect options are explained as follows:

64-QAMand256-QAMare valid modulation schemes but do not provide the highest data rates in 802.11ax.

4096-QAMis not supported by the 802.11ax standard and is therefore invalid.

Thus,1024-QAMis the modulation scheme that provides thehighest data rate level for 802.11ax devices.

According to the Webhooks - Mist document, two types of information that would be streamed through webhooks are:

Alerts, which are notifications that are triggered by certain events or conditions on the network.

SLE metrics of clients, which are service level expectations that measure the quality of experience for clients on various aspects such as connection, coverage, capacity, throughput, and roaming.

According to Coverage SLE, Asymmetry Downlink classifier tracks a client that transmits at lower data rate than AP to which it is connected.So the correct answer is A.Asymmetry Downlink

According to the exhibit, the organization has a total of two licenses for Marvis wireless, and one of them is in use. Therefore, the organization has one available license and one used license for Marvis wireless.

the Post-Install user role is also known as Installer role, which has a minimum level of access to the org, sites, and APs. It can do the initial installation such as claim AP to Org, assign/unassign AP, or place on map, etc., but cannot unclaim or remove the AP from the Org. Site and AP access is allowed based on timed grace period and/or explicit site access.

The exhibit shows a graph of the client’s roaming history over time. The x-axis represents the time and the y-axis represents the access point ID. Each dot on the graph indicates a roam event where the client switched from one access point to another.

The graph shows that the client roamed between different access points multiple times within a short period of time. This indicates that the client was experiencing frequent roams between different access points, which could affect its network performance and user experience.

InJuniper Networks Mist AI Wireless, Service Level Expectations (SLEs) are used to measure and assure real user experience across the wireless network. Each SLE is built on specificclassifiers, which break down failures into root causes such as DHCP, DNS, authentication, RF conditions, or application issues. Understanding which SLEs rely on DHCP classification is essential for accurate troubleshooting.

The two Wireless Assurance SLEs that include aDHCP classifierareSuccessful ConnectsandTime to Connect.

TheSuccessful Connects SLEmeasures whether client devices are able to complete the full connection process successfully. This process includes association, authentication, and critically,DHCP address assignment. If a client fails to obtain an IP address, the connection is considered unsuccessful, and the failure is explicitly classified as a DHCP issue within this SLE.

TheTime to Connect SLEmeasures how long it takes for a client to connect from the moment it initiates association until it is fully usable on the network. One of the key components of this timeline is theDHCP transaction time. Slow DHCP responses, retransmissions, or server delays directly increase the overall connection time, and Mist classifies these delays under DHCP within the Time to Connect SLE.

The other options are incorrect for the following reasons:

Roaming SLEfocuses on re-association, authentication, and mobility events, not DHCP, since IP addressing is typically retained during roaming.

Coverage SLEevaluates RF signal strength, SNR, and cell overlap, with no dependency on DHCP.

Throughput SLEmeasures data transfer performance after connectivity is established and does not analyze DHCP behavior.

Therefore, the correct answer isSuccessful Connects and Time to Connect, as both SLEs directly depend on and classifyDHCP-related performance and failureswithin Mist Wireless Assurance.
