正解：A、D
解説：
Reference:
According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, two layers of the OSI model where WLANs are located are:
Physical, which defines how data is encoded and transmitted over the wireless medium using radio waves.
Data Link, which defines how devices access and share the wireless medium using media access control (MAC) protocols.
質問 # 26
A customer is replacing their previous WLAN controller with a Mist Edge to maintain centralization of user traffic.
How does Mist Edge affect control plane forwarding and data plane forwarding in this scenario?
- A. Control plane forwarding applies to the Mist Edge and data plane forwarding applies to the Mist Edge.
- B. Control plane forwarding applies to the Mist Cloud and data plane forwarding applies to the Mist Cloud.
- C. Control plane forwarding applies to the Mist Edge and data plane forwarding applies to the Mist Cloud.
- D. Control plane forwarding applies to the Mist Cloud and data plane forwarding applies to the Mist Edge.
正解：D
解説：
Explanation
When a customer replaces their previous WLAN controller with a Mist Edge in order to maintain centralization of user traffic, control plane forwarding applies to the Mist Cloud while data plane forwarding applies to the Mist Edge. So the correct answer is A. Control plane forwarding applies to the Mist Cloud and data plane forwarding applies to the Mist Edge.
質問 # 27
You are troubleshooting a client that has had intermittent connectivity problems. Using Marvis to troubleshoot, you see that AP uptime is negatively affecting the client. When inspecting Marvis' troubleshooting response, which category should you select to see when the AP went offline?
- A. AP Metrics
- B. Location
- C. Correlation
- D. Classifiers
正解：A
質問 # 28
Click the Exhibit button.
A user opened a ticket. Upon troubleshooting, you determine that frequent roaming is the root cause of the problem.
Referring to the exhibit, which statement describes the roaming issue that the client is experiencing?
- A. There are frequent roams between different WLANs.
- B. There are frequent roams between different protocols.
- C. There are frequent roams between different access points.
- D. There are frequent roams between different bands.
正解：C
解説：
Explanation
The exhibit shows a graph of the client's roaming history over time. The x-axis represents the time and the y-axis represents the access point ID. Each dot on the graph indicates a roam event where the client switched from one access point to another.
The graph shows that the client roamed between different access points multiple times within a short period of time. This indicates that the client was experiencing frequent roams between different access points, which could affect its network performance and user experience.
質問 # 29
You are troubleshooting a client that has had intermittent connectivity problems. Using Marvis to troubleshoot, you see that AP uptime is negatively affecting the client. When inspecting Marvis' troubleshooting response, which category should you select to see when the AP went offline?
- A. Correlation
- B. Location
- C. AP Metrics
- D. Classifiers
正解：A
解説：
According to the Marvis - Mist document, Correlation is a category in Marvis' troubleshooting response that shows when the AP went offline. Correlation shows the correlation between events and SLEs for a given client or AP.
質問 # 30
You are installing and booting up your first Juniper Mist AP at your site.
By default, which two statements are correct in this scenario? (Choose two.)
- A. The AP will attempt to connect to the Mist cloud using port 8080.
- B. The AP will attempt to connect to the Mist cloud using port 443.
- C. The AP will send DHCP requests using the native VLAN.
- D. The AP will send DHCP requests with a VLAN ID of 10.
正解：B、C
解説：
According to the Initial AP Connection and VLANs & Static IP addresses - Mist document1, when a Juniper Mist AP boots up for the first time, it will expect to see a trunked port or the native VLAN=1 and will send a DHCP request on that VLAN. The AP will attempt to connect to the Mist cloud using port 443, which is the default HTTPS port.
質問 # 31

- A. all purchased APs
- B. all APs in inventory
- C. all APs assigned to sites that have connected to the cloud previously
- D. all APs assigned to sites
正解：C
解説：
Explanation
The AP Offline Marvis Action will consider all APs assigned to sites that have connected to the cloud previously for inclusion. So the correct answer is A. all APs assigned to sites that have connected to the cloud previously.
質問 # 32
What happens first when a client requests to join a WLAN?
- A. ARP request
- B. 802. 11 authentication
- C. DHCP discovery
- D. 802.11 association
正解：B
解説：
Reference:
According to the 802.11 Network Security Fundamentals - Cisco document, 802.11 authentication is the first step when a client requests to join a WLAN. 802.11 authentication is a process whereby the access point either accepts or rejects the identity of a client device to create resources.
