The API uses the RESTful architecture and supports JSON and XML formats2. You can use the API to automate and customize your Mist environment according to your needs2.
The GUI is a graphical user interface that allows you to access and manage your Mist environment through a web browser1. The GUI provides a user-friendly and intuitive way to configure and monitor your Mist devices, networks, sites, users, and policies3. The GUI also provides various features, such as dashboards, reports, analytics, insights, troubleshooting tools, and Marvis virtual network assistant3. You can use the GUI to easily and quickly set up and optimize your Mist environment3.
質問 # 55
Referring to the exhibit, what do you determine about the site's Time to Connect SLE metric?
- A. Successful connect averaged 1.6 seconds.
- B. Eighty percent of the Time to Connect failures are related to DHCP failures
- C. All clients cannot connect to the Internet.
- D. Time to Connect Association DHCP failures impacted 80% of users.
正解：B
解説：
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.
質問 # 56
Which Mist supported API is considered data-driven?
- A. Webhook
- B. RESTful
- C. WebSocket
- D. gRPC
正解：B
解説：
According to the Mist documentation1, the Dashboard API is a modern, RESTful API using HTTPS requests to a URL and JSON as a human-readable format. The API is available to any customer with a Mist account and is very well documented.
RESTful APIs are considered data-driven because they use HTTP methods (such as GET, POST, PUT, DELETE) to manipulate data resources on a server2. They also follow a set of design principles that make them scalable, uniform, and stateless.

質問 # 61
What does Mist with Wi-Fi Assurance do to detect a bad cable connected to an AP?
- A. It applies machine learning to telemetry data.
- B. It performs cable tests.
- C. It sends probe traffic through the cable connections.
- D. It monitors SNMP trap information.
正解：B
解説：
According to the Switch Testing Tools page, one of the features that Mist with Wi-Fi Assurance provides is the ability to run a cable test on the port provided1. This can help monitor the connection health of the cable on your specified port1. The cable test can show the length of the cable, the status of each pair, and any faults detected1. This feature can be accessed from the Utilities dropdown menu on the Switches page in the Mist dashboard1. The other options are not correct because they are not related to detecting a bad cable connected to an AP. SNMP trap information is a way of sending alerts from network devices to a management system. Probe traffic is a way of measuring network performance by sending packets between endpoints. Machine learning is a way of applying artificial intelligence to analyze data and learn from it.
質問 # 62
You just received the newest Mist AP and want to enable a feature that is only available at this time on Release Candidate 1.
In this scenario, using the Mist GUI, where would you determine which version of Release Candidate 1 is available for your AP?
- A. Support Tickets and Documentation -> Ports & Endpoints
- B. Support Tickets and Documentation -> Feature Updates
- C. Support Tickets and Documentation -> Mist Edge Updates
- D. Support Tickets and Documentation -> Firmware Updates
正解：D
解説：
Reference:
If you want to enable a feature that is only available on Release Candidate 1, you need to upgrade your AP to the latest firmware version that supports that feature. To do that, you can use the Firmware Upgrade feature in the Mist GUI, which allows you to automatically or manually upgrade multiple APs on your site1. To find out which version of Release Candidate 1 is available for your AP, you can go to Support Tickets and Documentation -> Firmware Updates in the Mist GUI. There, you will see a list of the latest firmware versions for different AP models, along with the release notes and the features they support2. You can also use the ? mark in the upper right of the UI to see the latest firmware and previous production releases1. You can then select the desired firmware version from the dropdown menu and start the upgrade process1.
質問 # 63
Which protocol does the REST API use?
- A. SNMP
- B. HTTP
- C. SSL
- D. syslog
正解：B
解説：
Reference:
The protocol that the REST API uses is HTTP. HTTP stands for Hypertext Transfer Protocol and is a standard protocol for exchanging information between different applications or services over the internet. HTTP defines a set of methods, such as GET, POST, PUT, and DELETE, that specify the type of action to be performed on a resource. HTTP also defines a set of status codes, such as 200 OK, 404 Not Found, and 500 Internal Server Error, that indicate the outcome of the request.
The REST API is an application programming interface that conforms to the design principles of the REST, or representational state transfer, architectural style. REST APIs provide a flexible, lightweight way to integrate applications and to connect components in microservices architectures. REST APIs rely on HTTP to transfer a representation of the state of the resource to the requester or endpoint. The representation can be in various formats, such as JSON, XML, HTML, or plain text.
質問 # 64
Which protocol is used by Mist access points to discover third-party switches?
- A. LLDP
- B. SNMP
- C. CDP
- D. ICMP
正解：C
質問 # 65
Which administrator role must you have to view audit logs?

- B. Super User
- C. Observer
- D. Network Admin
正解：B
質問 # 66
Which administrator role must you have to view audit logs?
- A. Installer
- B. Network Admin
- C. Observer
- D. Super User
正解：B
解説：
According to the web search results, the administrator role that you must have to view audit logs is Network Admin. Audit logs are records of the actions and changes that occur on the Mist platform, such as configuration updates, firmware upgrades, device claims, or user logins1. Audit logs can help network administrators monitor, troubleshoot, and audit their network by providing information such as the date, time, user, site, device, and description of each action1.
According to the Administrator Roles page, there are five types of roles that can be assigned to users in a Mist organization: Super User, Network Admin, Helpdesk, Observer, and Installer2. Each type of role has different read and write capabilities for the organization and its sites2. Network Admin is one of the roles that can view audit logs, as it has limited read/write access to all sites under the organization and can access organization-level features such as Audit Logs and Inventory2. Network Admin can also open/update support tickets from the GUI2.
質問 # 67
You are inviting a new administrator into a Mist organization.
In this scenario, which two roles are valid? (Choose two.)
- A. Observer
- B. Custom
- C. Advanced
- D. Installer
正解：A、D
