   A user calls the help desk for assistance configuring an Android phone with a new NFC-enabled speaker that will be used for an upcoming conference call. The user was unable to direct the phone's audio to the NFC speaker. Which of the following sequences should the help desk technician walk the customer through to accomplish this task?

   • AEnable NFC on the speaker. Ensure the speaker is less than 33ft (10m) from the Android phone. On the phone's Bluetooth settings menu for Connected Devices, select Pair New Device. Tap to accept the connection to the speaker when the prompt is displayed on the phone's screen.
   • BEnable NFC and Bluetooth on the Android phone. From the Android phone's Bluetooth settings menu for Connected Devices, select the Previously Connected Devices option. Select a listed device that most closely matches the speaker. Tap to accept the connection to the speaker when the prompt is displayed on the phone's screen.
   • CEnable NFC and Bluetooth on the Android phone. Tap and hold the Android phone to the spot on the speaker where the NFC logo is displayed. Accept the connection to the speaker when the prompt is displayed on the phone's screen.

   Show answer

   Answer: C

   Explanation

   C. Enable NFC and Bluetooth on the Android phone. Tap and hold the Android phone to the spot on the speaker where the NFC logo is displayed. Accept the connection to the speaker when the prompt is displayed on the phone's screen. Explanation: The question specifically mentions that the speaker is NFC-enabled, so the correct sequence involves enabling NFC on the Android phone and tapping it to the speaker to initiate the Bluetooth pairing process. Option A is close but mentions pairing through the phone's Bluetooth settings menu, which is not necessary when using NFC. Option B is incorrect as it instructs the user to select a previously connected Bluetooth device rather than using NFC. Option D is also incorrect as it suggests using Wi-Fi to connect to the speaker, which is not mentioned as an option in the question.

   A technician is configuring a workstation to be used as a VM host. After installing the necessary software, the technician is unable to create any VMs. Which of the following actions should be performed?

   • ADisable the BIOS password.
   • BEnable TPM.
   • CEnable multithreading.
   • DEnable Fast Startup.

   Show answer

   Answer: C

   Explanation

   TPM is not a requirement to start VMs. People are assuming information that is not in the question and this is usually the cause of second guessing these kinds of exams for most test takers. The question states nothing about Windows 11. In order to have a VM running on a system, the system needs to have hyperthreading and/or multicore processing. I work with VMs on a regular basis. TPM is used for encryption purposes of a drive and is required for Windows 11 installations, but again, where in the question does it state Windows 11 and not something like Ubuntu, or any other OS for that matter?

   A user on the marketing team uses various multimedia applications that consume a lot of memory. The user needs to install more RAM to run these applications effectively. When the user opens the computer case, the user sees four slots in two sets of colors. Which of the following memory types is MOST likely required?

   • ADual-channel
   • BTriple-channel
   • CSingle-channel
   • DQuad-channel
   • EError correction code RAM

   Show answer

   Answer: A

   Explanation

   CompTIA "a dual-channel motherboard might have four DIMM slots arranged in color-coded pairs. Each pair represents one channel. For example, channel A might be color-coded orange and channel B color-coded blue. Each slot in a pair represents one of the two sockets in the channel (A1 and A2, for instance)."

   Which of the following allows all VMs in a virtual environment to have RAM allocated for use?

   • AMeasured service
   • BContainerization
   • CSynchronization
   • DResource pooling

   Show answer

   Answer: D

   Explanation

   Containerization is close but incorrect as it does not involve "Guest OS"s, thus not a VM. Resource pooling chooses how much of a physical resource to allocate to each VM

   Which of the following 802.11 standards supports both 5GHz and 2.4GHz channel frequencies?

   • A802.11a
   • B802.11ac
   • C802.11b
   • D802.11g

   Show answer

   Answer: B

   Explanation

   I remember these by 802.11a = legacy = 5GHz b & g = boy and girl on 2.4ghz. Boys drool, girls rule. Girls are faster than boys - go with highest n = plays nice and plays with both 2.4 and 5 ghz. ax = axe - splits wood into 2, splits into 2.4 and 5 ac = wifi5, 5 ghz, but backwards compatible (only option left since n and ax are not options…) n is not an option so must be ac.

   A hardware technician is configuring a laptop, and the network administrator requires the network settings to be static. The technician successfully pings the servers by IP address but cannot ping the UNC path. Which of the following is the cause of this issue?

   • ADomain Name System
   • BGateway
   • CSubnet
   • DIP address

   Show answer

   Answer: A

   Explanation

   The cause of the issue is most likely related to the Domain Name System (DNS). When the technician can ping servers by IP address but cannot ping by UNC path, it means that the laptop is able to connect to the network, but is having trouble resolving the names of the servers using DNS. The UNC path uses server names instead of IP addresses, so if the DNS is not configured correctly, the laptop will not be able to resolve the names and connect to the servers. Therefore, the technician should verify the DNS settings on the laptop and ensure that the correct DNS server addresses are configured.

   A technician has set up a new conference room with a TV and a video soundbar. The technician wants to test the system with a conference call. During the test, the TV speaker produces sound, but the soundbar does not. Which of the following is the MOST likely cause of the issue?

   • AThe volume on the TV needs to be turned up.
   • BThe conference call needs to be unmuted for audio.
   • CAn incorrect HDMI cable is being used.
   • DThe TV's HDMI-ARC port is not being used.

   Show answer

   Answer: D

   Explanation

   D. The TV's HDMI-ARC port is not being used. The most likely cause of the issue is that the technician is not using the TV's HDMI-ARC (Audio Return Channel) port. This port is specifically designed to send audio signals from the TV back to the soundbar, allowing for a single HDMI cable to be used for both video and audio. If the technician is using a different HDMI port, such as one labeled "HDMI IN," the soundbar will not receive any audio signals.

    A technician is setting up a projector for a videoconferencing system. When the user attempts to connect a laptop to the system, the system displays the following error message: no source found The user tries multiple cables and inputs on the projector. Which of the following should the user try NEXT?

    • ACheck the bulb on the projector and replace it with a new one.
    • BCheck the display settings on the computer and set them to extend/duplicate.
    • CReplace the projector with another known-good one and try again.
    • DReplace the video card on the machine that is plugged in to the projector, as it has gone bad.

    Show answer

    Answer: B

    Explanation

    Via CompTIA "If no image is displayed on the monitor or projector, first make sure that the display device is plugged in and turned on. Check that the monitor is not in standby mode (press a key or cycle the power to the monitor to activate it). You may also need to use controls on the monitor itself to adjust the image or select the appropriate data source or input channel. For example, if there is no image on the screen, check that the monitor is set to use the HDMI port that the computer is connected to, rather than an empty DVI port. These o n-screen display (OSD) menus are operated using buttons on the monitor case. As well as input control, you can usually find settings for brightness, color/contrast, and power saving."
