Online Access Free JN0-452 Practice Test

What is a key characteristic of the 2.4 GHz Wi-Fi band compared to the 5 GHz band?

• A.It is less susceptible to interference from non-Wi-Fi devices like microwaves.
• B.It offers higher maximum data rates.
• C.It has more non-overlapping channels.
• D.Its signals travel farther and penetrate obstacles better.

An administrator uses the Marvis conversational assistant and asks, "Why is my client failing to connect?" Marvis responds with a root cause analysis indicating an "Authentication Failure" due to "RADIUS Server Missing Events." What does this specific Marvis insight mean?

• A.The RADIUS server is online but is explicitly rejecting the client's credentials.
• B.The client is using the wrong PSK password.
• C.The client device is not configured as a Network Access Service (NAS) client on the RADIUS server.
• D.The APs at the site cannot reach the configured RADIUS server, causing EAP requests to time out.

What is a key difference in RF propagation characteristics between the 2.4 GHz and 5 GHz bands?

• A.2.4 GHz signals are more easily absorbed by common building materials like drywall and concrete.
• B.5 GHz signals generally have a longer effective range in open-air environments.
• C.2.4 GHz signals, having a longer wavelength, are better at penetrating physical obstacles.
• D.The 5 GHz band is more susceptible to interference from non-Wi-Fi devices like Bluetooth and microwave ovens.

What is the primary function of Marvis Minis?

• A.To collect detailed telemetry data exclusively from wired Juniper EX switches.
• B.To provide a simplified version of the Marvis conversational assistant for mobile devices.
• C.To automatically generate and assign WxLAN policies based on observed traffic patterns.
• D.To act as a network digital twin, proactively simulating user connections to test the health of network services like DHCP, DNS, and application reachability.

An administrator is configuring the Service Level Expectations for a new site. They want to ensure that users can connect to the network quickly.
Which SLE allows the administrator to define a specific time-based goal, in seconds, for the entire connection process (Association, Authorization, DHCP)?

• A.Time to Connect
• B.Successful Connects
• C.Capacity
• D.Roaming
