Juniper JN0-451 Mist AI, Specialist JNCIS-MistAI Exam Practice Test
Question 1
Some users cannot connect to the network. You want to identify these users. In Marvis, which query accomplishes this task?
Answer : B
According to the Marvis - Mist document, unhappy clients is a query that can be used in Marvis to identify users who cannot connect to the network. Unhappy clients shows a list of clients who have experienced poor service level expectations (SLEs) such as connection failures, coverage issues, or low throughput.
Question 2
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.
Question 3
What is the AP's role in the IEEE 802.1X authentication process?
Answer : A
In the IEEE 802.1X authentication process, the AP acts as an authenticator.
According to the Lecture 5 - Security - Part 1 document, the AP's role in the IEEE 802.1X authentication process is to act as an authenticator. This means that the AP acts as a gatekeeper between the client device (supplicant) and the RADIUS server (authentication server). The AP forwards authentication messages between the supplicant and the server and grants or denies network access based on the server's response.
Question 4
Click the Exhibit button.
Referring to the exhibit, which percentage of connection attempts failed on the access point named LD_RS_Support?
Answer : B
The 37% of Successful Connects suggest that 63% failed -- however, these are spread between both LD_Testbed_MD and LD_RS_Support. If the only AP with connection issues was LD_RS_Support then the reverse math may have worked.
Question 5
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?
Answer : B
The Compatible WLAN data rate setting is required for legacy 2.4 GHz scanners to connect to the WLAN.
Question 6
You are asked to set up occupancy analytics for an office that has an existing Mist AP.
Which three types of devices are counted by default? (Choose three.)
Answer : A, B, C
Mobile app clients, which are devices that have a mobile app installed with the Mist SDK or BLE beaconing enabled.
Cellular clients, which are devices that have cellular connectivity and can be detected by Mist APs using LTE sensing.
Wi-Fi clients, which are devices that have Wi-Fi connectivity and can be detected by Mist APs using Wi-Fi scanning.
Question 7
Which two terms correctly describe transmissions over Wi-Fi? (Choose two.)
Answer : A, B
Transmissions over Wi-Fi are shared medium and half-duplex.
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.
