• Question 927:

  An engineer is installing a 500W power supply in a server that requires continuous availability. Which of the following is the most suitable type of power supply for the application?

  A. Redundant
  B. Modular
  C. Switched-mode
  D. Semi-modular
  A. Redundant

  ---

  Explanation

  A redundant power supply is a type of power supply that consists of two or more independent units that can provide power to the same device or system. A redundant power supply can increase the reliability and availability of the device or system, because if one unit fails, the other unit can take over and continue to provide power without interruption. A redundant power supply is often used in servers that require continuous availability, such as web servers, database servers, or file servers.

• Question 928:

  A technician is working to replace a single DDR3 RAM module on a laptop that has two occupied slots_ When the technician tries to tum on the laptop, the computer starts beeping and does not pass POST The technician double-checks the newly installed RAM and notices a motherboard message indicating low voltage. Which of the following is the most likely cause of this Issue?

  A. Faulty power adapter
  B. Incorrect BIOS settings
  C. Failing CMOS battery'
  D. Unsupported memory
  D. Unsupported memory

  ---

  Explanation

  Memory modules are physical components that store data and instructions for the computer to access and process. Memory modules have different specifications and features, such as type, speed, capacity, voltage, and form factor. These specifications and features must be compatible with the motherboard and the processor of the computer, otherwise the memory modules may not work properly or cause errors. In this scenario, the technician is working to replace a single DDR3 RAM module on a laptop that has two occupied slots. DDR3 stands for Double Data Rate 3, and it is a type of memory technology that offers faster performance and lower power consumption than its predecessors. DDR3 RAM modules have different variants, such as DDR3L, DDR3U, or DDR3R, which have different voltage requirements. For example, DDR3L operates at 1.35V, DDR3U operates at 1.25V, and DDR3R operates at 1.5V. When the technician tries to turn on the laptop, the computer starts beeping and does not pass POST. POST stands for Power-On Self-Test, and it is a process that checks the hardware components and functionality of the computer before loading the operating system. If POST detects an error or a failure, it may produce a series of beeps or codes to indicate the problem. The number and pattern of beeps or codes may vary depending on the manufacturer or model of the computer. The technician double-checks the newly installed RAM and notices a motherboard message indicating low voltage. This means that the motherboard is not receiving enough power from the memory module to operate normally. This could indicate that the memory module is not compatible with the motherboard or the processor, or that it is defective or damaged. The most likely cause of this issue is that the technician installed an unsupported memory module that has a lower voltage than what the motherboard or the processor requires. To resolve this issue, the technician should remove the newly installed RAM module and replace it with a compatible one that has the same voltage as the existing ones. The technician should also check the specifications and features of the motherboard and the processor to ensure that they support the type, speed, capacity, and form factor of the memory modules. The technician should also follow proper safety precautions when handling memory modules, such as wearing an anti-static wrist strap, avoiding physical damage or static discharge, and aligning the notches correctly.

• Question 929:

  A. Restart the Videoconference.
  B. Replace the laptop.
  C. Check the audio inputs.
  D. Try another microphone.
  C. Check the audio inputs.

  ---

  Explanation

  The technician should check that the audio inputs are configured correctly for the videoconference software and that they are not muted or disabled.The technician should also make sure that the microphone is plugged in properly and that it

  is not faulty or damaged.If possible, the technician should test the microphone on another device or use another microphone on the same device to isolate the problem.

  A university student was able to boot from a live Linux CD on a computer in a shared space on campus. Which of the following will BEST prevent this type of action from occurring in the future?

  A. Require TPM security features.
  B. Set a boot password.
  C. Disable all media options.
  D. Enable secure boot.
  D. Enable secure boot.

  ---

  Explanation

  Enabling secure boot will verify the digital signature of the bootloader and operating system, ensuring that the system only boots from trusted and authorised sources. This can prevent booting from an unauthorised live CD or other external media. The best way to prevent booting from a live Linux CD on a computer in a shared space on campus is to enable secure boot. Secure boot is a feature that ensures that the system only runs software that is signed by an authorized party. This means that the system will not boot from any unauthorized media, including live Linux CDs. Secure Boot is a feature that ensures that the system only runs software that is signed by an authorized party. This means that the system will not boot from any unauthorized media, including live Linux CDs. Secure Boot is an important security feature designed to prevent malicious software from loading when your PC starts up (boots)1. Booting from a live Linux CD is a process that allows you to run a Linux operating system from a CD or DVD without installing it on your hard drive. This can be useful for testing or troubleshooting purposes. To boot from a live Linux CD, you need to insert the CD or DVD into your computer's CD/DVD drive and restart your computer. Most systems are set up to automatically boot from the CD/DVD drive, but if your system is not set up this way, you may need to change a system setting to boot from a Linux CD/DVD.
