NEW QUESTION # 44
You are asked to configure Mist lo send e-mail alerts lo 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 emails.
What Is the problem in this scenario?
- A. The organization does not have sufficient alert subscriptions.
- B. Your e-mail server is blocking e-mail from Mist.
- C. The user e-mail addresses are not correctly formatted.
- D. The affected administrators have not enabled e-mail notifications in their Mist My Account settings.
Answer: D
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.

How does Mist determine the location of clients in an Indoor setting?
- A. probability surface
- B. trilateration
- C. triangulation
- D. GPS
Answer: B
Explanation:
* Understanding Location Determination in Mist:
Mist uses advanced methods to determine the location of clients in an indoor setting.
* Possible Methods:
Triangulation: Uses angles to determine position, but not typically used by Mist.
GPS: Not feasible indoors due to signal limitations.
Probability Surface: Involves calculating the probability of a client's location, but not the primary method used.
Trilateration: Uses the distance from multiple known points to determine the exact location.
* Mist's Method:
Mist primarily uses trilateration to determine the location of clients by measuring the distance from at least three access points.

NEW QUESTION # 60
Which two statements about WLAN templates are correct? (Choose two.)
- A. They can be deployed to a certain site.
- B. They can be deployed to a policy.
- C. They can be deployed to the whole organization.
- D. They can be deployed to a certain switch.
Answer: A,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) (CertEnsure).
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 (CertEnsure).
Incorrect Options:
Deployed to a Switch: WLAN templates are not deployed to individual switches. They are specific to wireless configurations and thus pertain to access points and wireless settings.
Deployed to a Policy: While policies can be part of WLAN configurations, templates themselves are not deployed directly to policies. Policies are typically components within the templates.

NEW QUESTION # 61
Manager asks you to set up a new WLAN that Is Open Access and does not allow any connected clients to communicate with each other, m the WLAN configuration, which feature would you use to separate the clients?
- A. Filter ARP.
- B. Configure isolation.
- C. Hide SSID.
- D. Configure geofence.
Answer: B
Explanation:
To set up a new WLAN that is Open Access and prevents connected clients from communicating with each other, you should use the Configure Isolation feature. This feature, often referred to as client isolation, ensures that each client can only communicate with the access point and not with other clients on the same WLAN.
