JN0-451 Exam Dumps - Mist AI - Specialist (JNCIS-MistAI)

According to the exhibit, the WLAN has a minimum basic rate of 24 Mbps for both 2.4 GHz and 5 GHz bands. This corresponds to the high-density data rate setting in Mist, which disables all data rates below 24 Mbps. This setting is recommended for high density designs, where clients have enough signal strength and quality to operate at higher rates.

Syslog is a protocol that can be used to forward event messages from Mist to an external log collector.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, syslog is a feature that enables forwarding event messages from Mist to an external log collector. Syslog messages can be sent over UDP or TCP protocols.

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.

According to the Mist documentation1, WLANs are wireless networks that can be configured with different settings such as SSID, security, encryption, authentication, etc. WLANs can be created and managed at different levels of hierarchy in the Mist cloud.

The site group level allows you to create and apply WLANs to a group of sites that share common characteristics or requirements2. This helps you to simplify and standardize your WLAN configuration across multiple sites.

The site level allows you to create and manage WLANs for a specific site that may have unique needs or preferences1. This gives you more flexibility and granularity for your WLAN configuration at each site.

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.

According to the JNCIS-MistAI Certification page3, a Marvis Actions Missing VLAN notification indicates that an access point is missing a VLAN that is configured on other access points in the same site.
