Question 1

You are asked to forward event messages from Mist to an external log collector.

In this scenario, which feature would enable this capability?

Asyslog

Bwebhooks

CNETCONF

DSNMP traps

Answer : A

Syslog is a protocol that can be used to forward event messages from Mist to an external log collector.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, syslog is a feature that enables forwarding event messages from Mist to an external log collector. Syslog messages can be sent over UDP or TCP protocols.

Question 2

Site A is configured with a WLAN and a policy. The administrator creates a configuration template at the organization level with additional policies for the same WLAN and mentions Site A in this template.

In this scenario, which statement is correct?

AThe policy that is created in the config template at the organization level will execute first.

BThe policy created at the organization level can be applied to a site group, not to an individual site.

CThe policy that is created at the site level will execute first.

DThere is no option to mention the site in the config template at the organization level.

Answer : D

According to the Juniper Mist Wireless Deployment Service Datasheet1, a configuration template at the organization level can be applied to a site group, not to an individual site. Therefore, there is no option to mention the site in the config template at the organization level.

Question 3

Which two terms correctly describe transmissions over Wi-Fi? (Choose two.)

Ashared medium

Bhalf-duplex

Cfull-duplex

Dpoint-to-point medium

Answer : A, B

Transmissions over Wi-Fi are shared medium and half-duplex.

According to the IEEE 802.11 - Wikipedia document2, two terms that correctly describe transmissions over Wi-Fi are:

Shared medium, which means that multiple devices use the same wireless channel and have to compete for access and avoid collisions.

Half-duplex, which means that devices can either transmit or receive data at a time, but not both simultaneously.

Question 4

According to the 802.11 standard, how wide are 2.4 GHz band OFDM channels?

A5 MHz

B22 MHz

C20 MHz

D3 MHz

Answer : C

According to the 802.11 standard, OFDM channels in the 2.4 GHz band are 20 MHz wide.

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, OFDM channels in the 2.4 GHz band are 20 MHz wide according to the 802.11 standard.

Question 5

You are deploying multiple Mist APs across many sites in your network. You must ensure that you can group similar devices together to easily apply consistent WxLAN policies across multiple sites.

Which configuration object should be used to accomplish this behavior?

Aorganization labels

Bdevice profile

CRF template

Dradio management

Answer : B

When deploying multiple Mist APs across many sites in your network and grouping similar devices together to easily apply consistent WxLAN policies across multiple sites, you should use device profiles.

Question 6

Which access points (APs) will be considered for inclusion in the AP Offline Marvis Action?

Aall APs assigned to sites that have connected to the cloud previously

Ball APs assigned to sites

Call APs in inventory

Dall purchased APs

Answer : A

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 isA. all APs assigned to sites that have connected to the cloud previously.

Question 7

Which two statements correctly describe an extended service set (ESS)? (Choose two.)

AEach BSS within the ESS share a common BSSID.

BEach BSS within the ESS has its own unique BSSID.

CThe SSID is common across all BSSs within the ESS.

DThe SSID is unique across all BSSs within the ESS.

Answer : B, C

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, an extended service set (ESS) is a group of basic service sets (BSSs) that share a common SSID and are connected by a distribution system (DS). Each BSS within the ESS has its own unique BSSID, which is the MAC address of the AP.
