NEW QUESTION # 16
Which administrator role is based on a timed grace period for Mist site and AP configuration access?
- A. Installer
- B. Helpdesk
- C. Network Admin
- D. Observer
Answer: A
Explanation:
Reference:
According to the Administrator Roles page, the Installer role is based on a timed grace period for Mist site and AP configuration access1. The Installer role has minimum access to the organization and can do the initial installation tasks such as claim AP to Org, assign AP to site, or place on map, etc1. However, the Installer role cannot unclaim or remove the AP from the Org1. The site and AP access for the Installer role is based on a timed grace period after the last modified time, which is by default 7 days1. This means that the Installer role can only access the site and AP for 7 days after the last configuration change1. The Installer role uses the API and Mist AI App, and has no access to the native Admin UI1.

- B. The Organization ID is the encrypted version of the Organization Name field.
- C. The Organization ID is used to identify the organization when using APIs.

The Organization ID is a unique identifier that is randomly created by the system when you create a new organization in the Mist portal. The Organization ID is used to identify the organization when using APIs, such as the REST API or the GraphQL API. You can find your Organization ID in the Organization > Settings page in the Mist portal12.
The Organization ID is not the encrypted version of the Organization Name field. The Organization Name field is a user-defined name that can be changed at any time. The Organization ID is a system-generated string that cannot be changed.
The Organization ID is not manually defined by the user. The user cannot choose or modify the Organization ID. The user can only create or edit the Organization Name field.
NEW QUESTION # 23
Referring to the exhibit, what do you determine about the site's Time to Connect SLE metric?
- A. Eighty percent of the Time to Connect failures are related to DHCP failures
- B. All clients cannot connect to the Internet.
- C. Time to Connect Association DHCP failures impacted 80% of users.
- D. Successful connect averaged 1.6 seconds.
Answer: A
Explanation:
The correct answer is B. Eighty percent of the Time to Connect failures are related to DHCP failures. This is what you can determine about the site's Time to Connect SLE metric from the exhibit. The exhibit shows a root cause analysis chart that displays the Service Level Metrics and the Classifiers for the site. The Service Level Metrics section shows the percentage of time to connect, which is the time it takes for a client device to connect to the wireless network. The Classifiers section shows the percentage of authorization, association, internet services, and DHCP, which are the steps involved in the connection process. The blue line connects the two sections and shows the correlation between them.
The exhibit shows that the site has a Time to Connect SLE metric of 20%, which means that only 20% of the client devices were able to connect to the wireless network within the expected time. The exhibit also shows that 80% of the Time to Connect failures are related to DHCP failures, which means that 80% of the client devices were not able to obtain an IP address from the DHCP server. This indicates that there is a problem with the DHCP service or configuration at the site.
NEW QUESTION # 24
What are two characteristics of the 2.4 GHz band when compared to the 5 GHz band? (Choose two.)
- A. shorter wavelength
- B. more congestion
- C. less non-Wi-Fi interference
- D. lower frequency
Answer: B,D
Explanation:
Reference:
The correct answer is B. lower frequency and D. more congestion. These are two characteristics of the 2.4 GHz band when compared to the 5 GHz band. The 2.4 GHz band uses lower frequencies than the 5 GHz band, which means that it can penetrate solid objects better and have more range1. However, the lower frequencies also mean that the 2.4 GHz band has less bandwidth and speed than the 5 GHz band1. The 2.4 GHz band is also more congested than the 5 GHz band, as it has fewer non-overlapping channels and more interference from other devices and routers that use the same frequency band23. The 5 GHz band, on the other hand, has more non-overlapping channels and less interference, which makes it faster and more reliable23.

A user called a help desk to report a Wi-Fi issue.
In this scenario, what information must be provided for Marvis to troubleshoot the issue? (Choose two.)
- A. the time of the incident
- B. the MAC address of the client device
- C. user home address
- D. the access point to which the client was connected
Answer: A,B
Explanation:
A user called a help desk to report a Wi-Fi issue. In this scenario, the information that must be provided for Marvis to troubleshoot the issue are the MAC address of the client device and the time of the incident. These are two of the essential parameters that Marvis needs to identify and analyze the wireless client and its connection history.
The MAC address of the client device is a unique identifier that allows Marvis to locate and track the client on the wireless network. The MAC address can be found on the device settings, label, or sticker, depending on the device type. The MAC address can also be obtained from the Mist portal or the Mist AI App by searching for the client name or IP address.
The time of the incident is the approximate date and time when the user experienced the Wi-Fi issue. The time of the incident can help Marvis narrow down the scope of the troubleshooting and focus on the relevant data and events. The time of the incident can be specified in various formats, such as "today", "yesterday", "last week", "10 minutes ago", "5 pm", etc.
To troubleshoot a Wi-Fi issue using Marvis, you can use phrases such as "troubleshoot client <MAC address> on <time>" or "how was client <MAC address> on <time>" in the Marvis Conversational Assistant window. Marvis will show you the details of the client's connection status, performance, issues, and recommendations.
