JN0-451 Exam Dumps - Juniper JNCIS-MistAI Questions and Answers

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.

Basic data rates are the required data rates that all devices on a wireless network must support in order to connect to the network. These rates are used for management and control frames and can affect the performance of the network.

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, basic data rates are required data rates that all devices must support to communicate on a WLAN.

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 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.

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.

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.

When deploying three WLAN 2.4 GHz networks in your US-based site while ensuring that each network frequency is unique and does not overlap with other frequency channels, you should use OFDM channels 1, 6 and 11. So the correct answers are B.1, D.6, and A.11.

According to the Initial AP Connection and VLANs & Static IP addresses - Mist document1, when a Juniper Mist AP boots up for the first time, it will expect to see a trunked port or the native VLAN=1 and will send a DHCP request on that VLAN. The AP will attempt to connect to the Mist cloud using port 443, which is the default HTTPS port.

The Compatible WLAN data rate setting is required for legacy 2.4 GHz scanners to connect to the WLAN.

According to the Data Rates - Mist document4, the WLAN data rate setting that is required for legacy 2.4 GHz scanners to connect to the WLAN is Compatible. This setting enables all data rates from 1 Mbps to 54 Mbps for both 2.4 GHz and 5 GHz bands. This setting is recommended for legacy devices that need low data rates to connect.
