   A user can make and receive voice calls but cannot send or receive MMS text messages on a smartphone. Which of the following is the most likely cause of the issue?

   • AThe mobile data service is disabled.
   • BThe SIM card is defective.
   • CThe device is outside the cellular coverage area.
   • DAirplane mode is enabled.

   Show answer

   Answer: A

   Explanation

   In this scenario, the most likely cause of the issue is: A. The mobile data service is disabled. MMS (Multimedia Messaging Service) requires mobile data to be enabled to send and receive messages that contain multimedia content such as pictures, videos, or audio files. If the mobile data service is disabled on the smartphone, the user will still be able to make and receive voice calls (which typically use the cellular network) but will be unable to send or receive MMS messages.

2. Question 472 · 624 in bank

   A technician is setting up storage in a server that only has SAS connectors for storage. The technician wants the server to utilize RAID 10 for increased performance. Which of the following storage types should the technician install?

   • ANVMe M.2
   • BMechanical
   • CmSATA
   • DOptical

   Show answer

   Answer: B

   Explanation

   Since the server only has SAS connectors for storage and the technician wants to utilize RAID 10 for increased performance, the most appropriate storage type to install would be: B. Mechanical. Mechanical hard drives (HDDs) with SAS interfaces are commonly used in RAID configurations, including RAID 10, to provide increased performance and fault tolerance. While NVMe M.2 drives offer high performance, they require M.2 slots, which may not be available in servers designed for SAS storage. mSATA drives are typically used in laptops and smaller form factor devices, and optical drives are not suitable for RAID configurations.

   Given the following output from a cable tester:

   

   Which of the following tools should the technician use to resolve this issue? (Choose two.)

   • ALoopback plug
   • BNetwork tap
   • CToner probe
   • DCrimper
   • EPunchdown tool
   • FWi-Fi analyzer

   Show answer

   Answer: DE

   Explanation

   The correct tools to resolve the issue shown in the cable tester's output are D. Crimper and E. Punchdown tool (not C. Toner probe as most voted). Here's why: The cable tester output shows an issue with the wiring, as pins are mismatched or not connected properly. This usually indicates that the cable needs to be re-terminated or re-crimped. D. Crimper: This tool is used to attach RJ45 connectors to the end of network cables. If the connector is not crimped properly, it can cause miswiring like in the output. E. Punchdown tool: This tool is used to terminate cables into a patch panel or keystone jack, ensuring proper connectivity for each wire. If there is a problem with the termination of cables, the punchdown tool is required to fix it. Why C. Toner probe is incorrect: A toner probe is used to trace cables and identify where they run, but it doesn't fix wiring issues. It helps locate a cable, but wouldn't resolve the miswiring or open connections displayed in the cable tester's output. Therefore, the correct answer is D. Crimper and E. Punchdown tool to fix the termination and crimping issues in the cable.

   A technician is trying to set up a computer to dual boot from both Windows and Linux. The technician believes that a setting is preventing the computer from accessing the flash drive with the OS image prior to loading the OS. Which of the following settings should the technician check?

   • APXE
   • BUEFI
   • CACL
   • DTPM

   Show answer

   Answer: B

   Explanation

   The setting that controls the boot order and can potentially affect the ability to access a flash drive with the OS image prior to loading the OS is: B. UEFI (Unified Extensible Firmware Interface). UEFI is responsible for initializing hardware components and loading the operating system. It provides options for configuring the boot order, including specifying which devices the computer should attempt to boot from first. If the UEFI settings are not configured to allow booting from USB flash drives or other removable media, the computer may not recognize the flash drive with the OS image during the boot process.

   A frequently used projector continuously shows a message to clean the air filters. The technician checks the filters, and they are dean. Which of the following preconfigured settings is causing the projector to show the message frequently?

   • AImage calibration
   • BHours of use
   • CTemperature
   • DImage source

   Show answer

   Answer: B

   Explanation

   The message to clean the air filters on the projector is often triggered by preconfigured settings related to the: B. Hours of use. Projectors typically have built-in timers that track the number of hours the lamp has been in use. When the lamp has been used for a certain number of hours, the projector may prompt the user to clean the air filters as a preventive maintenance measure to ensure proper ventilation and cooling. Even if the filters are clean, the projector's internal timer may still trigger the message based on the accumulated hours of lamp usage.

   A technician receives a phone call from a traveling sales representative indicating that the maps application on a phone is not working. The representative runs a speed test on the phone and gets ~10Mbps in both directions. Which of the following settings should the technician check first to troubleshoot the issue?

   • AAirplane mode
   • BPRL
   • CGPS
   • DLTE

   Show answer

   Answer: C

   Explanation

   Given that the issue is related to the maps application not working on the phone despite adequate internet speed, the technician should first check: C. GPS (Global Positioning System). The GPS functionality is essential for mapping applications to accurately determine the device's location. Even if the internet connection speed is sufficient, if the GPS is not functioning correctly or if the location services are disabled, the maps application may not work as expected.

   A technician installed four hard drives in a RAID 5 configuration. After creating the array, the technician is unable to copy files to the array within Windows. Which of the following should the technician do next?

   • ADecrease the number of drives to three.
   • BPartition and format the volume.
   • CRebuild the array.
   • DCheck the hot spare status.

   Show answer

   Answer: B

   Explanation

   Given that the technician has successfully configured the RAID 5 array but is encountering issues with copying files to it within Windows, the most appropriate next step would be to: B. Partition and format the volume. When setting up a RAID array, the raw storage space needs to be partitioned and formatted with a file system before it can be used for storing files. Since the technician has already configured the array, the next logical step is to partition and format the volume within the RAID array to make it accessible and usable within the Windows operating system.
