NEW QUESTION # 29
Which two statements about WLAN templates are correct? (Choose two.)
- A. They can be deployed to a certain switch.
- B. They can be deployed to a certain site.
- C. They can be deployed to the whole organization.
- D. They can be deployed to a policy.
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.

NEW QUESTION # 31
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 affected administrators have not enabled e-mail notifications in their Mist My Account settings.
- B. Your e-mail server is blocking e-mail from Mist.
- C. The user e-mail addresses are not correctly formatted.
- D. The organization does not have sufficient alert subscriptions.
Answer: A
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 # 32
