Answer : A

The correct answer is A. 900 MHz. This is the frequency band that will have the farthest usable range under ideal conditions.The range of a wireless signal depends on several factors, such as the transmit power, the antenna gain, the receiver sensitivity, the propagation environment, and the interference level1.However, in general, lower frequency signals can travel farther than higher frequency signals, as they have less attenuation (signal loss) and can penetrate solid objects better2.The 900 MHz band is a lower frequency band than the 2.4 GHz, 5 GHz, and 6 GHz bands, which are commonly used for Wi-Fi and other wireless technologies3. Therefore, the 900 MHz band will have the farthest usable range under ideal conditions.However, the 900 MHz band also has less bandwidth and speed than the higher frequency bands, as well as more interference from other devices that use the same band3. Therefore, the 900 MHz band may not be suitable for some wireless applications that require high data rates or low latency.

Answer : D

This is a machine learning method that involves rewarding and punishing an agent for its actions in an environment. The agent learns by trial and error to maximize the rewards and minimize the penalties.This is how Mist AI performs Radio Resource Management (RRM) to optimize the RF radio waves that transmit network traffic in wireless LANs1.

Answer : B

The step that you would take to immediately find out the status of the Mist cloud is to visit https://status.mist.com. This is the official website that provides real-time information and updates on the availability and performance of the Mist cloud services, such as the Mist portal, the Mist API, the Mist AI engine, and the Mist regions. You can also subscribe to receive notifications via email, SMS, or webhook when there are any incidents or maintenance events affecting the Mist cloud.

Answer : A, B

machine learning and deep learning are two domains that comprise artificial intelligence (AI).AI is the ability of a computer or a robot to perform tasks that normally require human intelligence, such as reasoning, learning, or problem-solving1.AI can be applied to various fields and industries, such as healthcare, finance, education, and entertainment1.

Machine learning is a subset of AI that enables computers to learn from data and experience without being explicitly programmed2.Machine learning uses algorithms and statistical models to analyze data and find patterns, correlations, or predictions2.Machine learning can be used for various tasks, such as image recognition, natural language processing, recommender systems, or fraud detection2.

Deep learning is a subset of machine learning that uses artificial neural networks to mimic the structure and function of the human brain3.Deep learning can process large amounts of complex and unstructured data, such as images, videos, or texts3.Deep learning can be used for various tasks, such as face recognition, speech recognition, natural language generation, or self-driving cars3.

Answer : B, D

Two prerequisites for adopting Juniper switches for Wired Assurance area Wired Assurance licenseandan account on manage.mist.com. These are the two essential requirements that enable the cloud-based management and AI features of the Juniper Mist platform for the switches.

A Wired Assurance license is a subscription that allows you to onboard, configure, and monitor your Juniper EX Series Switches from the Juniper Mist cloud. A Wired Assurance license also provides access to the Mist AI engine, which delivers insights, automation, and service-level expectations (SLEs) for your wired network.You can purchase a Wired Assurance license from a Juniper partner or reseller1.

An account on manage.mist.com is a user account that allows you to access the Juniper Mist portal and the Juniper Mist API. The Juniper Mist portal is a web-based interface that lets you manage and troubleshoot your wired and wireless networks from anywhere.The Juniper Mist API is an application programming interface that lets you integrate and automate your network operations with third-party applications and services2.
