NEW QUESTION # 68
Regarding roaming, which device determines when it is time to connect to another AP?

• A. the primary AP
• B. the current AP
• C. the client device
• D. the gateway router

Answer: C

Explanation:
According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, roaming is the process of moving a wireless client device from one AP to another while maintaining network connectivity. The client device determines when it is time to connect to another AP based on its own roaming algorithm and criteria.

NEW QUESTION # 69

NEW QUESTION # 70
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. downstream
• B. out-of-band
• C. upstream
• D. revenue
• E. proxy

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 # 74
Which Wireless Assurance SLE provides information on Opportunistic Key Caching (OKC)?

• A. Capacity
• B. Roaming
• C. Time to Connect
• D. Coverage

Answer: B

Explanation:
Reference: https://www.mist.com/documentation/service-level-expectations-sle/ According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, the Wireless Assurance SLE that provides information on Opportunistic Key Caching (OKC) is Roaming. OKC is a fast roaming technique that allows wireless clients and the WLAN infrastructure to cache only one PMK for client association with a WLAN, even when roaming between multiple APs.
