NEW QUESTION # 26
Which two statements about the Mist UI are true? (Choose two.)
- A. It can initiate a packet capture on cloud uplink.
- B. It can initiate a BLE packet capture.
- C. It can initiate a wireless packet capture.
- D. It can initiate a wired packet capture.
Answer: C,D
Explanation:
Reference:
According to the official Mist documentation1, wireless packet captures are helpful when trying to dissect and dig down into the root cause of any wireless issue between a client and AP. You can determine if packets being sent are actually reaching their destination as well as identify if packets are corrupted. With the enhanced packet capture flow, Mist also introduced the ability to capture packets on the wired side of your network as well. This data is captured from the Eth0 port of your AP, and will examine the packets between the AP and the rest of your wired network. This includes any RADIUS, DHCP, or DNS servers you have set up.
The Mist UI does not support BLE packet capture or packet capture on cloud uplink.

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.

Click the Exhibit button.
Referring to the exhibit, which Marvis language would you use to query Mist about an issue?
- A. natural language
- B. Python
- C. query language
- D. SQL
Answer: A
Explanation:
Referring to the exhibit, the Marvis language that you would use to query Mist about an issue is natural language. Natural language is the language that humans use to communicate with each other, such as English, Spanish, or Hindi. Natural language is different from formal or programming languages, such as SQL, Python, or query language, which have strict rules and syntax.
Marvis is a virtual network assistant that allows you to interact with the Mist network using natural language commands. You can type or speak your queries to Marvis in plain English and get answers in a conversational manner. For example, you can ask Marvis questions like "Why is my Wi-Fi slow?" or "How many devices are connected to AP1?" or "Show me the throughput of SSID2". Marvis will understand your intent and provide relevant information, insights, and actions.
Marvis uses natural language processing (NLP) to analyze and interpret your queries. NLP is a branch of artificial intelligence that deals with the interaction between computers and human languages. NLP involves various tasks, such as speech recognition, natural language understanding (NLU), natural language generation (NLG), sentiment analysis, machine translation, etc.
NEW QUESTION # 40
You want to review client information about a specific AP.
In this scenario, where in the UI would you look?
- A. Access Points
- B. AP Insights
- C. Client Insights
- D. SLEs
Answer: A
Explanation:
If you want to review client information about a specific AP, you can go to the Access Points page in the Mist UI. The Access Points page shows a list of all the APs that are managed by your site, along with their status, model, firmware, location, and other details1. You can also use the search bar or the filter options to find a specific AP by its name, MAC address, serial number, or tag1.
By clicking on an AP from the list, you can access the AP Details page, which shows more information about the AP, such as its configuration, events, alerts, and insights2. On the AP Details page, you can also see the client information about the AP by clicking on the Clients tab2. The Clients tab shows a list of all the clients that are associated with the AP, along with their status, MAC address, IP address, hostname, role, SSID, VLAN, and other details2. You can also use the search bar or the filter options to find a specific client by its name, MAC address, IP address, or tag2.
By clicking on a client from the list, you can access the Client Details page, which shows more information about the client, such as its connection history, events, alerts, and insights3. On the Client Details page, you can also see the performance metrics of the client, such as its signal strength, data rate, latency, packet loss, throughput, and SLE scores3. You can also use the Troubleshoot button to launch Marvis virtual network assistant and get answers to your questions about the client3.
Therefore, if you want to review client information about a specific AP in the Mist UI, you can look at the Access Points page and then navigate to the AP Details page and the Clients tab.
