NEW QUESTION # 15
Which two statements correctly describe Mist claim codes and activation codes? (Choose two.)
- A. Claim codes may be used to claim only one AP.
- B. Claim codes may be used to claim multiple APs at once.
- C. An activation code is printed on a sticker on the AP.

NEW QUESTION # 16
You scheduled downtime to push the latest firmware to all the APs you deployed at the site. You verified that all of the APs are working fine. When you go back to work, you notice no complaints from the users. When you check the AP page, you notice that several APs have not rolled out with the latest firmware.
In this scenario, how does Marvis categorize this issue in the Marvis Action dashboard?
- A. The missing VLAN Marvis Action is displayed.
- B. The non-compliant Marvis Action is displayed.
- C. The port flap Marvis Action is displayed.
- D. The high CPU Marvis Action is displayed.
Answer: B
Explanation:
When several APs fail to update to the latest firmware during a scheduled downtime, Marvis categorizes this issue as a "non-compliant" action.
This categorization indicates that some APs are not adhering to the intended firmware version policy, which could potentially affect network performance or security. The non-compliant Marvis Action provides administrators with the necessary information to identify and rectify the issue, ensuring all APs are updated as required.
NEW QUESTION # 17
You are asked to configure Mist to send e-mail alerts to your organization administrators, who all have mailboxes that reside on the same e-mail server. Alerts are being generated and are visible in the Mist GUI, but only some administrators are receiving the alert e-mails.
What is the problem in this scenario?
- A. The user e-mail addresses are not correctly formatted.
- B. The affected administrators have not enabled e-mail notifications in their Mist My Account settings.
- C. The organization does not have sufficient alert subscriptions.
- D. Your e-mail server is blocking e-mail from Mist.
Answer: B
Explanation:
Identify the Problem: Alerts are being generated and visible in the Mist GUI, but only some administrators receive the alert emails.
Possible Issues:
User email addresses not correctly formatted.
Email server blocking Mist emails.
Insufficient alert subscriptions.
Administrators not enabling email notifications.
Root Cause:
Since some administrators receive the alerts, email formatting and server blocking issues can be ruled out.
If alert subscriptions were insufficient, no administrators would receive the alerts. The most likely cause is that the affected administrators have not enabled email notifications in their Mist My Account settings.
Resolution:
Ensure that all administrators have enabled email notifications in their Mist My Account settings.

NEW QUESTION # 21
Which protocol does Mist cloud use to send and receive data to connected access points?
- A. HTTPS
- B. SSH
- C. PPTP
- D. MQTT
Answer: A
Explanation:
Mist Cloud Communication Protocol: The Mist cloud platform uses HTTPS (Hypertext Transfer Protocol Secure) to communicate with connected access points. This ensures that the data sent and received is encrypted and secure, adhering to modern security standards(Juniper Networks).
Security and Reliability: Using HTTPS provides a secure channel over which configuration changes, updates, and monitoring data can be safely transmitted between the Mist cloud and the access points. This protocol is widely accepted and trusted for secure communications over the internet.
NEW QUESTION # 22
Which operation does an HTTP POST perform?
- A. create
- B. read
- C. delete
- D. write
Answer: A
Explanation:
An HTTP POST operation performs the "create" function in web communications. This method sends data to a server to create a new resource. For example, when you submit a form on a website, the data is sent to the server using a POST request, which then creates a new entry in the database.

NEW QUESTION # 25
A user has reported a network outage. After locating the user, you find that the switch interface facing the user is down but there is no alert in the Mist UI. You want to ensure that in the future, you receive an alert when a switch interface is down. You have already verified that the Critical Switch Port Down alarm is configured and enabled on the Alerts Configuration page.
In this scenario, which action in the Mist UI will satisfy the requirement?
- A. Enable the Critical Switch Port Up alarm on the Alerts Configuration page.
- B. Disable the Critical Switch Port Down alarm on the Alerts Configuration page.
- C. Navigate to the switch in the Mist UI and modify the Port Configuration to enable the Up/Down Port Alerts setting for the interface.
- D. Navigate to the switch in the Mist UI and modify the Port Profile configuration to enable Persistent (Sticky) MAC Learning for the Port Profile.
Answer: C
Explanation:
To ensure that you receive alerts when a switch interface goes down, you need to enable the Up/Down Port Alerts setting for the specific interface. This setting can be configured by navigating to the switch within the Mist UI and modifying the port configuration. Enabling this setting ensures that any changes in the port status, such as going down, will trigger an alert.
This is critical for proactive network monitoring and to promptly address any connectivity issues.

- A. They can be deployed to a policy.
- B. They can be deployed to the whole organization.
- C. They can be deployed to a certain site.
- D. They can be deployed to a certain switch.
Answer: B,C
Explanation:
WLAN Templates Overview: WLAN templates in Mist AI are used to standardize and manage wireless configurations across multiple locations and devices. They help in maintaining consistent wireless settings and policies throughout the network.
Deployment to the Whole Organization: WLAN templates can indeed be deployed at the organization level. This allows the configurations defined in the template to be applied across all sites and access points within the organization. This approach simplifies the management and ensures uniformity across the network(Juniper Networks).
Deployment to a Certain Site: WLAN templates can also be applied to specific sites. This is useful for organizations with multiple sites having unique wireless requirements. By applying templates at the site level, administrators can tailor configurations to meet local needs while still maintaining control through central management.
