Juniper JN0-451 JNCIS-MistAI Exam Questions Instant Access

Question 1

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?

AControl plane forwarding applies to the Mist Cloud and data plane forwarding applies to the Mist Edge.

BControl plane forwarding applies to the Mist Edge and data plane forwarding applies to the Mist Edge.

CControl plane forwarding applies to the Mist Cloud and data plane forwarding applies to the Mist Cloud.

DControl plane forwarding applies to the Mist Edge and data plane forwarding applies to the Mist Cloud.

Answer : A

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 isA. Control plane forwarding applies to the Mist Cloud and data plane forwarding applies to the Mist Edge.

Question 2

Referring to the exhibit, what would a guest user be able to do?

AUse Gmail and Slack.

BUse the Internet, except for Gmail and Slack.

CUse the HP Printer and Internet.

DUse only the Intranet.

Answer : B

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It typically establishes a barrier between a trusted internal network and an untrusted external network, such as the Internet .

Question 3

Your organization has recently purchased new VoIP handsets. All of the VoIP handsets fail to connect to the corporate WLAN. However, all other devices connect successfully. You expect that there might be a bug with the new handsets. The vendor asks you to provide a pcap file of the handsets' connection attempts.

Which Juniper Mist feature will provide this file?

ADynamic Packet Capture

BService Level Expectations

CClients Insights

DAlerts dashboard

Answer : D

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide2, Dynamic Packet Capture is a feature that enables capturing packets from a client device and downloading them as a pcap file. This file can be used for troubleshooting purposes or sent to a vendor for analysis.

Question 4

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.)

AThe AP will attempt to connect to the Mist cloud using port 443.

BThe AP will send DHCP requests using the native VLAN.

CThe AP will send DHCP requests with a VLAN ID of 10.

DThe AP will attempt to connect to the Mist cloud using port 8080.

Answer : A, B

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.

Question 5

Click the Exhibit button.

Users are occasionally having problems connecting to the Internet using Wi-Fi. You suspect possible interference from a neighboring Wi-Fi network.

Referring to the exhibit, which Wi-Fi Assurance SLE and classifier would provide information about this issue?

AThroughput and Network Issues

BCapacity and Non Wi-Fi Interference

CCoverage and Weak Signal

DCapacity and Wi-Fi Interference

Answer : D

The Wi-Fi Assurance SLE and classifier that would provide information about possible interference from a neighboring Wi-Fi network are Capacity and Wi-Fi Interference.

Question 6

When does a Mist AP actually begin transmitting BLE?

AWhen it is claimed and placed on a site.

BWhen it is placed on a floor plan.

CWhen BLE is enabled at the Organization level.

DWhen BLE is enabled for the AP.

Answer : B

According to the Location - how it works - Mist document1, a Mist AP actually begins transmitting BLE when it is placed on a floor plan. This is because the Mist cloud uses the floor plan information to calculate the optimal BLE transmission pattern for each AP.

Question 7

Which two statements are true about 802.1X/EAP? (Choose two.)

ACredentials are exchanged with a RADIUS server prior to the 4-way Handshake.

BCredentials are exchanged with a RADIUS server after the 802.11 Association.

CCredentials are exchanged with a RADIUS server after the 4-way Handshake.

DCredentials are exchanged with a RADIUS server prior to the 802.11 Association.

Answer : A, B

According to Wikipedia1, 802.1X is an IEEE Standard for port-based network access control (PNAC). It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN using Extensible Authentication Protocol (EAP) over wired IEEE 802 networks and over 802.11 wireless networks, which is known as ''EAP over LAN'' or EAPOL.

The authentication process involves three parties: a supplicant (the client device), an authenticator (the network device such as an access point), and an authentication server (typically a RADIUS server). The supplicant must provide valid credentials to the authenticator before it can access the network resources.

The credentials are exchanged with a RADIUS server prior to the 4-way Handshake because the 4-way Handshake is used to establish encryption keys between the supplicant and authenticator after successful authentication2.The credentials are exchanged with a RADIUS server after the 802.11 Association because the 802.11 Association is used to establish a logical link between the supplicant and authenticator before authentication can take place3.
