質問 # 25
Which statement is correct about Bluetooth and BLE?

  • A. Bluetooth and BLE use the same radio channels.
  • B. BLE is an upgrade to Bluetooth.
  • C. Bluetooth and BLE are compatible.
  • D. BLE is a newer technology than Bluetooth.

正解：A

解説：
The correct answer is B. Bluetooth and BLE use the same radio channels. Bluetooth and BLE are both wireless technologies that operate in the 2.4 GHz ISM band1. They use the same 40 channels, each with a bandwidth of 1 MHz2. However, Bluetooth and BLE are not compatible, as they use different protocols and modulation schemes2. BLE is a newer technology than Bluetooth, as it was introduced in 2010 as part of the Bluetooth 4.0 specification3. BLE is designed to be more energy-efficient and suitable for low-power devices that transmit small amounts of data3.


質問 # 26
Which two domains comprise artificial intelligence (AI)? (Choose two.)

  • A. deep learning
  • B. virtualization
  • C. SIEM
  • D. machine learning

正解：A、D


質問 # 27
Which two Mist-supported APIs are considered event-driven? (Choose two.)

  • A. Webhook
  • B. RESTful
  • C. WebSocket
  • D. gRPC

正解：A、C

解説：
According to the web search results, WebSocket and Webhook are two Mist-supported APIs that are considered event-driven. Event-driven APIs are APIs that allow the server to push information to the client asynchronously, instead of requiring the client to poll the server for updates. Event-driven APIs can provide real-time data, decoupled systems, and improved scalability and performance.
WebSocket is a protocol that enables bidirectional communication between a client and a server over a single TCP connection1. WebSocket allows the server to send messages to the client without waiting for a request, and vice versa1. WebSocket can be used for event-driven APIs that require continuous and interactive data exchange, such as chat applications, online games, or live streaming1.
Webhook is a way of sending data from the server to a third-party application or service when a certain event occurs2. Webhook allows the server to notify the client about an event, such as a new order, a payment confirmation, or a user registration2. Webhook can be used for event-driven APIs that require one-way notifications or integrations with other platforms, such as Slack, Splunk, or ServiceNow2.


質問 # 28
How should APs be deployed for location-based services (LBS)?

  • A. with the LED facing the floor
  • B. with the AP mounted on a wall
  • C. with the LED facing the ceiling
  • D. with the LED facing a wall

正解：B


質問 # 29

Which Marvis Action category should you use in this situation?

  • A. Application
  • B. AP
  • C. Connectivity
  • D. Clients

正解：C


質問 # 30

In this scenario, what is expected from the Mist Location Engine?

  • A. login splash page
  • B. coordinates
  • C. sensor device information
  • D. product advertisements

正解：B


質問 # 31
Which two statements are correct about creating Mist sites? (Choose two.)

  • A. You can only create and manage a single site with a Mist account.
  • B. You can create and manage multiple sites with a Mist account.
  • C. A Mist site can only belong to a single organization.
  • D. A Mist site can belong to multiple organizations.

正解：B、C

解説：
Reference:
The correct statements about creating Mist sites are:
A Mist site can only belong to a single organization. An organization is a logical grouping of sites and devices that share common settings and policies. A site is a physical location that contains one or more Mist devices. A site can only be associated with one organization and cannot be shared or moved to another organization1.
You can create and manage multiple sites with a Mist account. A Mist account is a user account that allows you to access the Mist portal and the Mist API. You can create and manage multiple sites within an organization or across different organizations with a Mist account, depending on your administrator role and permissions2.


質問 # 32
Mist cloud supports single sign-on in which two scenarios? (Choose two.)

  • A. Wi-Fi guest login access
  • B. admin login to the Mist portal
  • C. account login used for the RESTful API
  • D. account login used for NETCONF

正解：A、B

解説：
According to the web search results, Mist cloud supports single sign-on (SSO) in two scenarios: Wi-Fi guest login access and admin login to the Mist portal. SSO is a feature that allows users to log in to multiple applications or services with one set of credentials, without having to enter them repeatedly1. SSO can provide convenience, security, and efficiency for users and administrators1.
Wi-Fi guest login access is a scenario where users can access the Wi-Fi network as guests using their existing social media or email accounts, such as Facebook, Google, or LinkedIn2. Mist cloud supports SSO for Wi-Fi guest login access by integrating with various identity providers (IdPs), such as Azure AD, Okta, Ping Identity, or OneLogin2. Mist cloud can also use webhooks to send guest login data to third-party applications or services, such as Slack, Splunk, or ServiceNow2.
Admin login to the Mist portal is a scenario where administrators can access the Mist dashboard using their existing corporate accounts, such as Office 365, G Suite, or Active Directory3. Mist cloud supports SSO for admin login to the Mist portal by integrating with various IdPs, such as Azure AD, Okta, Ping Identity, or OneLogin3. Mist cloud can also use the REST API to automate and customize the admin login process3.


質問 # 33
Which administrator role must you have to view audit logs?

  • A. Network Admin
  • B. Installer
  • C. Observer
  • D. Super User

正解：D


質問 # 34
What are two characteristics of the 2.4 GHz band when compared to the 5 GHz band? (Choose two.)

  • A. lower frequency
  • B. shorter wavelength
  • C. more congestion
  • D. less non-Wi-Fi interference

正解：A、C

解説：
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.


質問 # 35
Which statement is correct about Bluetooth and BLE?

  • A. BLE is an upgrade to Bluetooth.
  • B. Bluetooth and BLE are compatible.
  • C. BLE is a newer technology than Bluetooth.
  • D. Bluetooth and BLE use the same radio channels.

正解：C


質問 # 36
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 -> Mist Edge Updates
  • C. Support Tickets and Documentation -> Feature Updates
  • D. Support Tickets and Documentation -> Firmware Updates

正解：D


質問 # 37
You are inviting a new administrator into a Mist organization.
In this scenario, which two roles are valid? (Choose two.)

  • A. Helpdesk
  • B. System Admin
  • C. Network Admin
  • D. Standard

正解：A、C

解説：
Reference:
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 Installer4. Each type of role has different read and write capabilities for the organization and its sites4. Helpdesk and Network Admin are two of the valid roles that can be selected when inviting a new administrator into a Mist organization4. Standard and System Admin are not valid roles in Mist.


質問 # 38
