Juniper Networks Documentation

Coverage Hole: Marvis Actions can identify coverage holes where the wireless signal is weak or absent, indicating potential areas that need additional access points or adjustments.

Health Check Failed: This action indicates that the health check, which monitors the performance and connectivity of an access point, has failed, suggesting issues that need to be addressed.

Enable Two-Factor Authentication (2FA): Adding 2FA to administrator logins significantly enhances security by requiring a second form of verification in addition to the password, making unauthorized access more difficult.

Enable a Password Policy: Implementing a strong password policy ensures that passwords meet certain complexity and length requirements, reducing the risk of brute force attacks.

Juniper Networks Documentation

In Mist's Service Level Expectations (SLE) framework, the Coverage SLE is responsible for reporting on RF interference.

The Coverage SLE monitors the strength and quality of the wireless signal, ensuring that clients are receiving adequate coverage throughout the network. It also identifies areas where RF interference might be degrading the signal quality.

By tracking RF interference, the Coverage SLE helps administrators diagnose and mitigate issues that could impact wireless performance and user experience.

Juniper Mist Wired Assurance provides several benefits aimed at simplifying network management and enhancing performance.

B. Ability to deploy campus fabric architectures in minutes based on intent: Wired Assurance leverages automation and intent-based networking to quickly deploy and manage complex campus fabric architectures. This feature significantly reduces the time and effort required to set up and maintain such networks.

C. Support for ZTP (Zero Touch Provisioning): Wired Assurance includes ZTP capabilities, which allow for the automatic provisioning and configuration of switches as soon as they are connected to the network. This reduces the need for manual intervention and speeds up the deployment process.

These features are part of a broader suite of tools that Wired Assurance provides to streamline network operations, improve reliability, and enhance visibility into network performance.

Installer Role in Mist:

The Installer role is designed for initial site setup and configuration.

Access Duration:

By default, the Installer role has temporary access for a specific duration to ensure security and control.

Default Access Duration:

7 days: Installers typically have access to a site for 7 days, enough time to complete initial setup and configuration before access expiration.

Conclusion:

The correct answer is A.
