NEW QUESTION # 68
You are asked to deploy a new Juniper Mist Edge VM for your customer.
Referring to the exhibit, which three interfaces are required to accomplish this task? (Choose three.)
- A. upstream
- B. out-of-band
- C. downstream
- D. proxy
- E. revenue
Answer: A,B,C
Explanation:
When deploying a Juniper Mist Edge VM (Virtual Machine), the networking architecture is designed to separate different types of traffic to ensure security, scalability, and efficient data handling. Unlike a traditional hardware controller that might use a single trunk port for all traffic, a Mist Edge VM specifically utilizes three primary logical interfaces to function within a data center environment.
The Out-of-Band (OOB) interface (A) is used exclusively for management and control plane traffic. This interface is what connects the Mist Edge to the Mist Cloud via an encrypted tunnel. It is through this port that the Mist Edge receives configuration updates, reports telemetry data to the AI engine, and allows administrators to monitor the health of the VM. By keeping this traffic out-of-band, Juniper ensures that management tasks do not compete with user data throughput.
The Upstream interface (D) is the "northbound" connection. Its primary role is to connect the Mist Edge to the core network or the internet for user data egress. When client traffic is tunneled from the Access Points (APs) to the Mist Edge, the Upstream interface is where that traffic is de-encapsulated and forwarded to the local network resources or the internet gateway. This interface typically connects to a core switch or a DMZ.
The Downstream interface (B) is the "southbound" connection. This is the entry point for the L2TPv3 or Mist Tunnel traffic coming from the Access Points. The APs establish a secure tunnel to this specific interface to transport user data across the Layer 3 network. This separation allows for granular firewall policies and ensures that the tunnel termination point is distinct from the management plane. While the term
"Revenue" (E) is often used in carrier-grade routing to describe data-carrying ports, Mist documentation specifically uses the terms Upstream and Downstream to define the data path.
NEW QUESTION # 69

What is the most likely cause of this issue?
- A. The DHCP server is not responding to client requests.
- B. The AP is experiencing high levels of RF interference.
- C. The client device does not support the security type configured on the WLAN.
- D. The AP and the connected switch have a duplex or speed mismatch on the wired link.
Answer: D
NEW QUESTION # 70
You receive a Marvis Actions alert informing you that there is a non-compliant AP at one of your sites.
What should you do to correct the problem?
- A. Install the correct version of firmware on the AP.
- B. Replace the AP with the correct hardware model.
- C. Disconnect the Rogue AP from your Ethernet switch.
- D. Request an RMA.
Answer: B
Explanation:
According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide2, a non- compliant AP is an AP that has a different hardware model than what is expected by the cloud configuration.
This can happen when an AP is replaced with an incorrect model or when an AP is moved to a different site group that has a different hardware model requirement. The solution is to replace the AP with the correct hardware model.

NEW QUESTION # 81
Which two statements are correct about channel bonding? (Choose two.)
- A. Bonding two channels together doubles the available bandwidth.
- B. Bonding two channels together doubles the number of available channels.
- C. Bonding two channels together doubles the noise floor.
- D. Bonding two channels together doubles the required device resources.
Answer: A,D
Explanation:
Channel bonding combines two adjacent channels to create a wider channel, effectively doubling the available bandwidth. However, this also doubles the required device resources such as power and processing.
According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, channel bonding is a technique that combines two adjacent channels into one wider channel to increase throughput.
This doubles the available bandwidth but also doubles the required device resources such as power and processing.

NEW QUESTION # 85
Which solution provides the greatest location accuracy?
- A. Ultra wide-band (UWB)
- B. Wi-Fi
- C. BLE badges
- D. SDK-enabled mobile application
Answer: A
Explanation:
InJuniper Networks Mist AI Wireless Real-Time Location System (RTLS)design discussions, multiple location technologies are commonly compared based on accuracy, reliability, and use-case suitability. Among the listed options,Ultra Wide-Band (UWB)provides thegreatest location accuracy.
UWB achieves superior accuracy because it usesvery short-duration radio pulses across a wide frequency spectrum, enabling extremely precisetime-of-flight (ToF)andtime-difference-of-arrival (TDoA) measurements. This allows UWB systems to determine device location withdecimeter-level precision, often in the range of10-30 centimeters, even in complex indoor environments. UWB is also highly resistant to multipath interference, which is a major limitation of Wi-Fi and BLE-based positioning systems.
By comparison:
* Wi-Fi-based locationrelies on RSSI and sometimes Angle of Arrival (AoA), typically achieving3-5 meter accuracyunder good conditions.
* BLE badgesimprove accuracy over Wi-Fi by using beacon proximity and BLE signal characteristics, often achieving1-3 meter accuracy, depending on beacon density and calibration.
* SDK-enabled mobile applicationscan enhance BLE or Wi-Fi accuracy by leveraging motion sensors and device context, but they are still constrained by the underlying RF technology and rarely reach sub- meter precision.
While Juniper Mist's vBLE and AI-driven probability surfaces deliver industry-leading accuracy for Wi-Fi and BLE-based RTLS use cases such as wayfinding, asset visibility, and proximity engagement,UWB remains the most accurate indoor positioning technology overall. Its precision makes it ideal for high- value use cases such as medical equipment tracking, industrial automation, and secure access control.
Therefore, the correct answer isUltra wide-band (UWB), as it provides thehighest level of location accuracy among the listed solutions.
