• Question 791:

  Which of the following should the data center hardware technician implement to ensure maximum uptime for customers' virtual machines?

  A. Line conditioner
  B. AC voltage regulator
  C. Uninterruptible power supply
  D. Cloud storage backup
  C. Uninterruptible power supply

  ---

  Explanation

  An uninterruptible power supply (UPS) can help ensure maximum uptime for customers' virtual machines by providing a backup power source in case of a power outage or other power-related issues. A line conditioner and AC voltage regulator are designed to stabilize the power supply, but do not provide backup power. Cloud storage backup is a way to backup data, but does not directly impact uptime.

• Question 792:

  A technician received a help desk ticket from a user who is unable to browse the internet_ Which of the following troubleshooting steps should the technician perform first?

  A. Establish a plan of action.
  B. Document the findings.
  C. Test the theory.
  D. Identify the problem
  D. Identify the problem

  ---

  Explanation

  The correct answer is

  D. Identify the problem. The first troubleshooting step that the technician should perform is to identify the problem. This means that the technician should gather information from the user and the system, and analyze the symptoms and the error messages to determine the nature and the scope of the issue. Identifying the problem can help to define the expected outcome, establish a theory of probable cause, and plan a course of action. The other options are not the first troubleshooting steps, but they are part of the troubleshooting process that should be performed after identifying the problem. Establishing a plan of action (option A) means that the technician should devise a strategy to resolve the issue, based on the theory of probable cause and the available resources. Testing the theory (option C) means that the technician should verify if the theory of probable cause is correct, by performing tests or experiments on the system or its components. Documenting the findings (option B) means that the technician should record and report the results of each troubleshooting step, as well as the final solution and outcome.

• Question 793:

  A graphic designer wants to upgrade to the fastest possible RAM for a desktop workstation. Which of the following types of RAM would be best for the designer to use?

  A. DDR2 SDRAM
  B. DDR3 SDRAM
  C. DDR4 SDRAM
  D. DDR5 SDRAM
  D. DDR5 SDRAM

  ---

  Explanation

  DDR5 SDRAM (Double Data Rate 5 Synchronous Dynamic Random-Access Memory) is the latest and fastest type of RAM for desktop workstations as of 2023. DDR5 SDRAM offers higher speeds, lower power consumption, greater capacity, and improved reliability than previous generations of DDR SDRAM. DDR5 SDRAM can operate at frequencies up to 8400 MHz, compared to 3200 MHz for DDR4 SDRAM, which means it can transfer data faster and more efficiently. DDR5 SDRAM also supports dual-channel memory, which allows two memory modules to work together and double the bandwidth. DDR5 SDRAM is compatible with the latest Intel and AMD processors that support the DDR5 standard. The other options are not as fast or suitable for a desktop workstation. DDR2 SDRAM, DDR3 SDRAM, and DDR4 SDRAM are older and slower types of RAM that have lower frequencies, higher voltages, and lower capacities than DDR5 SDRAM. DDR2 SDRAM, DDR3 SDRAM, and DDR4 SDRAM are not compatible with the latest processors that support DDR5 SDRAM, and require different motherboards and slots. DDR2 SDRAM, DDR3 SDRAM, and DDR4 SDRAM are more suitable for older or budget systems that do not require high performance or memory-intensive applications.

• Question 794:

  Isolating email attachments in a safe place until the attachments can be scanned for malware is defined as:

  A. an approve listing.
  B. a screened subnet.
  C. cross-platform virtualization.
  D. sandboxing.
  D. sandboxing.

  ---

  Explanation

  The correct answer is

  D. Sandboxing.

  Sandboxing is a security technique that isolates email attachments in a safe place until the attachments can be scanned for malware. A sandbox is a virtual environment that mimics the operating system and applications of the user, but prevents any changes or damage to the actual system. A sandbox can also monitor the behavior and activity of the attachments and detect any malicious code or actions12. An approve listing is a security technique that allows only trusted or authorized email senders or domains to be received by the user. An approve listing can help reduce spam and phishing emails, but it does not scan or isolate email attachments for malware3. A screened subnet is a security technique that creates a buffer zone between the internal network and the internet. A screened subnet uses firewalls and routers to filter and control the traffic that enters and exits the network. A screened subnet can help protect the network from external attacks, but it does not scan or isolate email attachments for malware. Cross-platform virtualization is a technology that allows running multiple operating systems and applications on the same physical machine. Cross-platform virtualization can help improve efficiency, flexibility, and compatibility, but it does not scan or isolate email attachments for malware.

• Question 795:

  Users working with large files back up the files to external hard drives. One user's files take longer to back up than other users' files. The user has tried backing up the files to other users' drives with the same results. Which of the following steps should the technician take first to correct this issue?

  A. Replace the hard drive's USB cable.
  B. Defragment the user's external hard drive.
  C. Update the storage drivers on the user's system.
  D. Instruct the user to compress the files.
  A. Replace the hard drive's USB cable.

  Which of the following adjustments would be MOST appropriate?

  A. Use the magnifier.
  B. Increase the resolution.
  C. Use haptic feedback.
  D. Utilize text-to-speech.
  A. Use the magnifier.

• Question 797:

  Several users who share a multifunction printer in an office have reported unintended, thin, vertical lines that cover the entire height of every page printed from the printer.

  Which of the following steps should a technician complete in order to MOST likely resolve this issue?

  A. Replace the printer paper with a new ream.
  B. Clear the print spooler on each computer.
  C. Reinstall the printer driver on each computer
  D. Perform the drum-cleaning procedure.
  D. Perform the drum-cleaning procedure.

  ---

  Explanation

  Thin, vertical lines on every printed page are usually caused by a dirty drum or toner cartridge. Performing the drum-cleaning procedure will likely resolve the issue.

• Question 798:

  A user installs a GPU and notices the screen resolution and picture quality are much lower than before the installation.

  Which of the following is most likely the cause of the issue?

  A. TheGPU is not compatible with the user's motherboard.
  B. Thecomputer does not have enough RAM installed to support the GPU.
  C. Theuser failed to install the appropriate OEM drivers.
  D. Thecomputer does not have a supported OS installed.
  C. Theuser failed to install the appropriate OEM drivers.

  ---

  Explanation

  When a new GPU is installed and results in lower screen resolution and picture quality, it's often because the appropriate OEM (Original Equipment Manufacturer) drivers for the GPU have not been installed. Without these drivers, the operating system may revert to generic drivers that do not fully support the GPU's capabilities, leading to suboptimal performance. Installing the correct OEM drivers should resolve the issue and allow the GPU to function at its intended performance level.

• Question 799:

  An administrator is replacing 15.000rpm hard drives in a server. Which of the following is the interface type the drives most likely use?

  A. IDE
  B. SAS
  C. eSATA
  D. SATA
  B. SAS

  ---

  Explanation

  SAS (Serial Attached SCSI) is an interface type that supports high-speed data transfer and high-performance hard drives, such as 15,000rpm drives. SAS drives are commonly used in servers that require fast access and reliability. IDE (Integrated Drive Electronics), eSATA (external SATA), and SATA (Serial ATA) are not suitable for 15,000rpm drives, as they have lower speed and performance.

  A. Replacing the printer pickup rollers
  B. Changing the printer spooler settings
  C. Using OEM-branded paper for this printer
  D. Increasing the corona wire voltage
  A. Replacing the printer pickup rollers
