Pass the Juniper JNCIS-MistAI JN0-451 Questions and answers with ValidTests

Referring to the exhibit and considering that it is in the USA, the WLAN with SSID Eero1234 is not configured to industry best practices while the WLAN with SSID NETGEAR24 is configured to industry best practices.

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.

According to the Juniper Mist Wireless Deployment Service Datasheet1, a configuration template at the organization level can be applied to a site group, not to an individual site. Therefore, there is no option to mention the site in the config template at the organization level.

If a customer wants to broadcast a WLAN at a certain time and day of the week, SSID scheduling should be configured

According to the SSID Scheduling - Mist document1, SSID scheduling is a feature that allows you to customize your WLAN by choosing the exact days and times to broadcast the SSID. This feature can be useful for scenarios where you want to limit the availability of a WLAN to a certain time and day of the week.

If a customer added an Apple TV in their conference room so that employees can easily share their screen but the Apple TV cannot be discovered by the employees’ devices, two settings that could be causing this problem are MDNS and Broadcast/Multicast. So the correct answers are A. MDNS and B. Broadcast/Multicast.

According to the Virtual Network Assistant | Juniper Networks US document3, two SLEs that measure the amount of time that it takes for a process to complete are:

Roaming, which measures how long it takes for a client to switch from one AP to another without losing connectivity.

Time to Connect, which measures how long it takes for a client to complete all steps of network access such as authentication, DHCP, and DNS.

Two authentication methods that would be used with a guest portal are social login and external portal. So the correct answers are A. social login and B. external portal.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide2, two authentication methods that can be used with a guest portal are:

Social login, which allows guests to log in using their social media accounts such as Facebook, Twitter, or Google.

External portal, which allows guests to log in using an external web server that hosts a custom portal page.

In this scenario, you would begin troubleshooting by checking the WLAN-level Pre-Shared Keys.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, you can configure a time-based setting for WLAN-level Pre-Shared Keys (PSKs) that will reset the key after a specified interval. This feature is useful for enhancing security and preventing unauthorized access. If a user reports that the Wi-Fi worked for a week and now it does not work, you should check the WLAN-level PSK settings and see if the key has been changed.

Channel bonding combines two adjacent channels to create a wider channel, effectively doubling the available bandwidth. However, this also doubles the required device resources such as power and processing.

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, channel bonding is a technique that combines two adjacent channels into one wider channel to increase throughput. This doubles the available bandwidth but also doubles the required device resources such as power and processing.
