All the data files must have the same columns, but at some point there are 4 new columns ({'B', 'A', 'D', 'C'}) and 1 missing columns ({'qtype'}).

This happened while the json dataset builder was generating data using

One of your coworkers has purchased an external Bluetooth trackpad to use with their tablet. They've turned to you, the company IT person, to install and configure it for them. What actions will you need to take? (Choose two.)	C,D	Analyzing each choice: A: Plug the device into a USB port - This is incorrect. Bluetooth devices do not need to be plugged into a USB port as they connect wirelessly. B: Install drivers - This may or may not be necessary. Some devices will require drivers to be installed, but many modern devices and operating systems will automatically handle this. C: Put the device in pairing mode and open Bluetooth settings on the tablet, then tap the trackpad - This is correct. To connect a Bluetooth device, you typically need to put it in pairing mode and then connect to it from the device you want to use it with. D: Go to Settings to configure speed and scrolling features - This is also correct. Once the device is connected, you may need to adjust settings like speed and scrolling to suit the user's preferences.

What types of networking will smart cameras often have built into them? (Choose two.)	A,D	A: Bluetooth - This is a possible answer. Bluetooth is a wireless technology that enables data exchange over short distances. It is commonly used in many devices, including smart cameras, for sharing data. B: IrDA - This is not a likely answer. IrDA stands for Infrared Data Association, a group of device manufacturers that developed a standard for transmitting data via infrared light waves. While it was popular in the past, it has largely been replaced by Wi-Fi and Bluetooth in most modern devices, including smart cameras. C: RJ-45 - This is not a likely answer. RJ-45 is a type of connector commonly used for Ethernet networking. While it's possible for a smart camera to have an RJ-45 port for wired networking, it's not as common as wireless options like Wi-Fi and Bluetooth, especially considering the flexibility and convenience of wireless connections. D: Wi-Fi - This is a possible answer. Wi-Fi is a wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. It is commonly built into smart cameras to allow them to connect to home networks and the internet.	Wired Network-1	null	[ "Bluetooth", "IrDA", "RJ-45", "Wi-Fi" ]
Which of the following statements about single-mode fiber-optic cable are true? (Choose all that apply.)

Which of the following are modes of SXP peers? (Choose two.)	A,C	Explanation: Every SXP peer session has a speaker and a listener. A speaker sends the mappings of IP addresses to SGTs. The listener receives those updates and records them. A peer can be configured to be both a speaker and a listener for the same peer if both support it. It may have numerous peers as well	Wired Network-3	null	[ "Speaker", "SGT-Reflector", "Listener", "SGT-Sender" ]
Router R1 currently supports IPv4, routing packets in and out all its interfaces. R1’s configuration needs to be migrated to support dual-stack operation, routing both IPv4 and IPv6. Which of the following tasks must be performed before the router can also support routing IPv6 packets? (Choose two answers.)	A,C	Of the four answers, the two correct answers show the minimal required configuration to support IPv6 on a Cisco router: enabling IPv6 routing ( ipv6 unicast-routing ) and enabling IPv6 on each interface, typically by adding a unicast address to each interface ( ipv6 address… ). The two incorrect answers list nonexistent commands	Wired Network-4	null	[ "Enable IPv6 on each interface using an [ipv6 address](vol1_gloss.xhtml#gloss_243) interface subcommand.", "Enable support for both versions with the ip versions 4 6 global command.", "Additionally enable IPv6 routing using the ipv6 unicast-routing global command.", "Migrate to dual-stack routing using the ip routing dual-stack global command." ]
