Identify the Problem: Suspected issue related to DHCP latency while troubleshooting a wireless client.

Understanding SLEs:

Capacity: Related to the number of clients and bandwidth.

Time to Connect: Measures the time taken for clients to connect, including DHCP latency.

Throughput: Measures the data transfer rate.

Coverage: Measures the signal strength and coverage area.

Selecting the Appropriate SLE:

Time to Connect is the relevant SLE as it includes metrics on DHCP latency, which affects the connection time.

Review the SLE:

Analyze the Time to Connect SLE to identify any latency issues with DHCP.

Real-time Assessment: Juniper Mist's Radio Resource Management (RRM) builds the channel plan based on real-time network assessments. It dynamically adjusts to changing conditions in the RF environment, ensuring optimal performance by continuously monitoring factors such as interference, client distribution, and usage patterns.

Automatic Tuning: RRM tuning happens automatically. Mist AI leverages reinforcement learning to continually optimize RF settings without manual intervention, adjusting channels, power levels, and other parameters in real-time to maintain optimal network performance.

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 managecomplex 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.

Reference: Juniper Networks documentation on Wired Assurance features and capabilities.

The exhibit displays an interaction sequence typical of RESTful APIs, which use HTTP methods such as GET, POST, PUT, and DELETE to perform operations on resources. RESTful APIs are characterized by their statelessness and reliance on standard HTTP methods, making them a popular choice for web services and applications.

RESTful Web Services Overview

The "Exceeded" status for a subscription means that the allowed usage defined within the subscription has been surpassed.

This typically refers to exceeding limits such as the number of devices, data usage, or other metrics specified in the subscription plan.

Exceeding these limits may require action such as upgrading the subscription plan to accommodate the additional usage.

Reference: Juniper Networks documentation on subscription status and management.

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.

Reference: Juniper Networks documentation on Mist SLEs and their specific metrics.

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.

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.
