the signal strength between APs

the client

the AP’s radio for a single SSID

NO.46 Which two Mist Aps would be used for BLE location? (Choose two.)

AP12

AP33

AP32

AP43

According to the JNCIS-MistAI Certification page2, two Mist APs that would be used for BLE location are AP33 and AP43. These are the only two models that support vBLE array technology, which enables accurate location services without physical beacons.

NO.47 Referring to the exhibit, what are two reasons why a Mist AP would have multiple IP addresses? (Choose two.)

One IP address is used for control traffic and one address is used for management traffic.

The Local Status Page is enabled in the site settings.

One IP address is used for redundancy.

A guest portal is configured on a tagged VLAN.

NO.48 You receive a Marvis Actions alert informing you that there is a non-compliant AP at one of your sites.
What should you do to correct the problem?

Request an RMA.

Disconnect the Rogue AP from your Ethernet switch.

Replace the AP with the correct hardware model.

Install the correct version of firmware on the AP.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide2, a non-compliant AP is an AP that has a different hardware model than what is expected by the cloud configuration. This can happen when an AP is replaced with an incorrect model or when an AP is moved to a different site group that has a different hardware model requirement. The solution is to replace the AP with the correct hardware model.

NO.49 What is meant when a Marvis Action is shown as “AI Validated”?

The issue which triggered an alert has been set to Resolved status.

Marvis has observed a new issue.

Marvis has observed a recurring issue.

Marvis has observed an issue that is no longer present.

Reference:
When a Marvis Action is shown as “AI Validated”, it means that Marvis has observed an issue that is no longer present.

NO.50 Click the Exhibit button.

Referring to the exhibit, which statement is correct about the Post-Install user’s role?

It is used for help desk monitoring and workflow for all sites.

It has access limited to installing APs and switches at all sites.

It has read-only access to all sites.

It has full access to all sites.

Explanation
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.

Stations only transmit when polled by the access point.

Transmit on a fixed schedule.

Reference:
According to the IEEE 802.11 – Wikipedia document, one thing that 802.11 stations perform to help avoid collisions on the WLAN medium is to listen to verify that the medium is free before transmitting. This is part of the carrier-sense multiple access with collision avoidance (CSMA/CA) mechanism that 802.11 stations use to coordinate access to the shared medium.

NO.53 You are deploying multiple Mist APs across many sites in your network. You must ensure that you apply consistent WxLAN and WLAN policies across all sites within the same organization.

site labels

an RF template

a device profile

a config template

NO.54 Which two statements are correct about the radio frequency rule of 10s and 3s? (Choose two.)

If the signal strength increases by 3 dB, the power is tripled.

If the signal strength decreases by 10 dB, the power is halved.

NO.55 You are installing and booting up your first Juniper Mist AP at your site.
By default, which two statements are correct in this scenario? (Choose two.)

The AP will attempt to connect to the Mist cloud using port 443.

The AP will send DHCP requests using the native VLAN.

The AP will send DHCP requests with a VLAN ID of 10.

The AP will attempt to connect to the Mist cloud using port 8080.

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.
