A technician is dispatched to troubleshoot a slow performance issue on a PC. Upon arrival, the technician immediately opens Task Manager and sees that CPU and RAM performance are within normal ranges. The technician then checks and verifies the speed and duplex settings and performance on the network card. The technician then temporarily disables the antivirus to see if performance is affected, and it is not. After re-enabling the antivirus, which of the following is the NEXT best stop for the technician to take?

• Check to see if insufficient hard drive space is causing the issue

• Update the operating system, drivers, and firmware on the PC

• Log into the PC with another user profile and test performance

• Shut down the PC, unplug the power for 30 seconds, and then boot the PC

A technician was called to check an unexpected clicking noise on a desktop that has become more frequent every time a video editing application is loaded. The system fans have been replaced, but the clicking noise remains. Diagnostics have been run on the video card. Which of the following should me the technician do FIRST?

• Replace the hard drive

• Do a System Restore

• Scan the system for viruses

• Replace the video card

• Perform a full data backup

A technician upgraded the memory on a server from two 8GB sticks to eight 32GB. The server memory is now at full capacity per the user guide. When the technician powers on the system, only 128 GB of memory is recognized by the OS and the BIOS. The technician decides to upgrade to the latest version of the firmware on the system, which does not help. Next, the technician installs the memory in sets of 64GB at a time. Each individual set of 64GB is fully recognized by the server. Which of the following will not allow the server to recognize all of the memory installed at the same time?

• The power supply is not supplying enough power for the memory

• The server is overheating when all of the memory is installed

• The memory has too many ECC errors and is shutting down

• The server needs DDR4 memory, and DDR3 is installed

A server needs a RAM upgrade, and a technician has been tasked with retrieving the RAM from storage and then installing it. Whish of the following is the BEST RAM type for the technician to retrieve?

• SODIMM

• Single Channel

• DDR4

• ECC

About one week ago, access to files on a network server became significantly slower. Today, network files are completely unavailable. A technician is able to make a remote connection to the server. Which of the following should the technician check NEXT?

• RAID 5 array

• Available storage space

• NIC configuration

• RAM utilization

A technician is configuring a high-performance workstation. The technician needs to choose storage for the boot drive with the highest performance possible. Which of the following drive types BEST meets this requirement?

• NVMe

• MicroSD

• 15K rpm

• USB flash

A technician is talking to end users about the specifications for an upgraded application server. The users of the application report that there cannot be any unscheduled downtime or data loss. Additionally, they would like the performance of the application to improve over the previous server in any way possible. The previous server running RAID 5. Which of the following RAID solutions should be implemented in this scenario?

• RAID 0

• RAID 1

• RAID 5

• RAID 10

A systems administrator receives a notification from the RAID controller that the RAID 5 array is degraded. Upon logging into the server, the administrator sees that on local disk 0, physical disk 2 has failed. Which of the following is the BEST course of action to take to resolve the problem?

• Schedule system downtime and replace physical disk 2. Wait until the array is rebuilt and confirm in the RAID controller that the system is no longer degraded

• Delete logical disk 0 and manually configure a new RAID array only using the known- good working drives. Wait until the array is rebuilt and confirm in the RAID controller that the system is no longer degraded

• Immediately replace physical disk 2. Wait until the arrays is rebuilt and confirm in the RAID controller that the system is no longer degraded

• In the controller, convert the RAID 5 array to RAID 0 array to avoid system downtime. Wait until the array is rebuilt and confirm in the RAID controller that the system is no longer degraded

A user is connected to a docking station with an optical drive and is trying to back up personal files to removable media but is encountering write errors. Which of the following is MOST likely cause of the errors?
