In this situation, which port must be allowed on your company's firewall for AP access to the Mist cloud?



Answer : B


According to the web search results, TCP/443 is the port that must be allowed on your company's firewall for AP access to the Mist cloud.TCP/443 is the port that is used for HTTPS, which is a secure version of HTTP that encrypts the data sent between the client and the server1.Mist APs use HTTPS to communicate with the Mist cloud and receive their configuration, firmware, and policies2.TCP/443 is also the port that is used for ep-terminator, which is a service that provides encrypted tunneling between Mist APs and the Mist cloud3. Therefore, TCP/443 is the port that must be allowed on your company's firewall for AP access to the Mist cloud.

Which administrator role must you have to view audit logs?



Answer : B

According to the web search results, the administrator role that you must have to view audit logs is Network Admin.Audit logs are records of the actions and changes that occur on the Mist platform, such as configuration updates, firmware upgrades, device claims, or user logins1.Audit logs can help network administrators monitor, troubleshoot, and audit their network by providing information such as the date, time, user, site, device, and description of each action1.

Question 3

Which statement is correct about Bluetooth and BLE?



Answer : B

The correct answer is B. Bluetooth and BLE use the same radio channels. Bluetooth and BLE are both wireless technologies that operate in the 2.4 GHz ISM band1. They use the same 40 channels, each with a bandwidth of 1 MHz2. However, Bluetooth and BLE are not compatible, as they use different protocols and modulation schemes2. BLE is a newer technology than Bluetooth, as it was introduced in 2010 as part of the Bluetooth 4.0 specification3. BLE is designed to be more energy-efficient and suitable for low-power devices that transmit small amounts of data3.


Question 4

According to the web search results, the statement that defines the total user minutes is the total number of minutes for which Mist has statistics for each client.Total user minutes is a metric that measures the amount of time that clients are connected to the wireless network and have data available for analysis1.Total user minutes is calculated by summing up the number of minutes that each client is associated to the network and has statistics collected by Mist1.Total user minutes can be used to evaluate the network performance, user experience, and service level expectations (SLEs) of the wireless network1.


Question 5

Answer : D


This is the earliest opportunity to configure an access point (AP) in the Juniper Mist cloud.According to the Juniper Mist documentation1, the steps to configure an AP are as follows:

Claim the AP to inventory: This step involves entering the serial number or MAC address of the AP in the Juniper Mist cloud portal, which will add the AP to the inventory and assign it a subscription.

Assign the AP to a site: This step involves selecting a site from the inventory and dragging and dropping the AP to the site. This will apply the site-level settings and policies to the AP.

Configure the AP settings: This step involves editing the AP settings, such as name, location, labels, templates, and radio profiles. This can be done individually or in bulk for multiple APs.
