QUESTION 62
Referring to the exhibit, you asked Marvis to troubleshoot a client. In this scenario, what did Marvis determine?

two authentication failures over this week

two DHCP failures today

DHCP errors over the past seven days

two authentication failures today

Reference: https://www.mist.com/documentation/mist-experience-marvis-client/ According to the exhibit, Marvis determined that there were two authentication failures today for the client device. This can be seen from the red dots on the timeline chart that indicate failed events and from the event details that show authentication failure as the reason.

QUESTION 63
Which pair of Wireless Assurance SLEs have a classifier on DHCP?

Roaming and Coverage

Time to Connect and Roaming

Coverage and Throughput

Successful Connects and Time to Connect

The Successful Connects and Time to Connect SLEs both include a DHCP classifier. They track whether a client successfully obtains an IP address and how long the DHCP process contributes to overall connection time, ensuring visibility into onboarding performance.

QUESTION 64
Your customer added an Apple TV in their conference room so that employees can easily share their screen. However, the Apple TV cannot be discovered by the employees’ devices.
Which two settings are causing the problem? (Choose two.)

MDNS

Broadcast/Multicast

Ignore Broadcast SSID Probe Requests

ARP

QUESTION 65
An administrator uses the Marvis conversational assistant and asks, “Why is my client failing to connect?” Marvis responds with a root cause analysis indicating an “Authentication Failure” due to “RADIUS Server Missing Events.” What does this specific Marvis insight mean?

The client is using the wrong PSK password.

The APs at the site cannot reach the configured RADIUS server, causing EAP requests to time out.

The RADIUS server is online but is explicitly rejecting the client’s credentials.

The client device is not configured as a Network Access Service (NAS) client on the RADIUS server.

QUESTION 66
How does a Juniper Access Point detect rogue and honeypot APs?

The Juniper Access Point uses all of its radios simultaneously to detect rogue and honeypot APs.

The Juniper Access Point detects rogue and honeypot APs only by communicating with its Layer
2 switch.

The Juniper Access Point uses its radios in round-robin fashion to detect rogue and honeypot APs.

The Juniper Access Point has a radio dedicated only for scanning and detecting rogue and honeypot APs.

Juniper Mist APs include a third, dedicated dual-band (2.4/5 GHz) radio whose sole job is background scanning – spectrum analysis, security monitoring, and detection of rogue and honeypot APs. Because this radio is separate from the two client-serving radios, the AP can continuously scan for threats without interrupting or degrading client traffic.

QUESTION 67
Which Juniper Mist LBS feature would be used to create a historical heatmap of visitor traffic patterns throughout a retail store?

Asset Visibility

User Engagement (via Zone Occupancy Analytics)

Proximity Tracing

vBLE Beacons

QUESTION 68
Under which hierarchy level would you create a new site configuration?

clients

location

access points

organization

QUESTION 69
An access point discovers switch information using which protocol?

CDP

ARP

SNMP

LLDP

Mist access points use LLDP (Link Layer Discovery Protocol) to discover switch information such as port, VLAN, and switch identity. This enables better visibility and automation within the Mist dashboard for troubleshooting and network management.

QUESTION 70
Which Wireless Assurance SLE provides information on Opportunistic Key Caching (OKC)?

Time to Connect

Roaming

Coverage

Capacity

QUESTION 71
When an AP is not yet claimed but is powered on and connected to the Internet, what state is it in?

Connected

Disconnected

Unclaimed

Site Assigned

QUESTION 72
Exhibit:

Referring to the exhibit, which client has the weakest connection to the WLAN?

Client 2

Client 4

Client 3

Client 1

InJuniper Networks Mist AI Wireless, the strength and quality of a client’s wireless connection are primarily evaluated usingRSSI (Received Signal Strength Indicator)andSNR (Signal-to-Noise Ratio).
These two metrics are core inputs into multiple Wireless Assurance SLEs, including Coverage and Throughput, and are reliable indicators when determining which client has the weakest WLAN connection.
From the exhibit, the key metrics for each client are:
* Client 1: RSSI-81 dBm, SNR11 dB
* Client 2: RSSI -71 dBm, SNR 21 dB
* Client 3: RSSI -67 dBm, SNR 25 dB
* Client 4: RSSI -70 dBm, SNR 22 dB
In wireless design,lower (more negative) RSSI values indicate weaker signal strength, andlower SNR values indicate poorer signal qualitydue to higher relative noise. Among all listed clients,Client 1 clearly has the weakest connection, as it has both:
* Thelowest RSSI(-81 dBm), indicating it is farthest from the AP or experiencing significant attenuation.
* Thelowest SNR(11 dB), which suggests the signal is only marginally stronger than the background noise.
Mist best practices typically consider RSSI values below -70 dBm and SNR values below ~20 dB as suboptimal for reliable performance, especially for higher modulation schemes. Client 1 falls well below these thresholds, making it the most likely to experience low data rates, retransmissions, and degraded user experience.
Mist AI would flag this client as having poor coverage and may recommend actions such as:
* Improving AP placement or density
* Adjusting RF power or channel plans
* Enforcing minimum RSSI thresholds
Therefore, based on both RSSI and SNR,Client 1has the weakest WLAN connection, makingOption Dthe correct answer.

QUESTION 73
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.)

QUESTION 74
An administrator connects a new AP45 to a switch port but notices it is not coming online. After checking the switch logs, they see the following:
LLDP Power Negotiation Log:
– Power Requested by PD: 29.3 W
– Power Granted by PSE: 15.4 W
Based on this log, what is the most efficient next step to bring the AP fully online?

Replace the Ethernet cable.

Reboot the access point.

Configure the switch port to provide 802.3at or 802.3bt power.

Claim the AP in the Mist dashboard.

QUESTION 75
A retail customer has legacy 2.4 GHz scanners that need to connect to the WLAN, but they are not connecting.
Which WLAN data rate setting is required for these devices to connect?

Custom Rates

Compatible

High Density

No Legacy

QUESTION 76
What is the purpose of a Device Profile in the Mist UI?

To apply a configuration to all devices within a specific site.

To apply specific settings (like disabling an LED or setting a static IP) to APs of a certain model.

To define a security policy for a type of client device (e.g., iPhone).

To create a profile for a user in the guest database.
