Explanation
Primary Array:
Drag and drop two 120 GB SSD hard drives to the primary array bay.
Open the primary array and select RAID 1 as the RAID level. RAID 1 provides fault tolerance of one drive, ability to function with only one drive, easily recoverable data, high redundancy, and very fast on reads. It also does not need to be scalable and uses the minimum number of drives (two) for RAID 1.
Confirm the configuration and close the primary array.
Secondary Array:
Drag and drop two 300 GB SSD hard drives to the secondary array bay.
Open the secondary array and select RAID 0 as the RAID level. RAID 0 provides the best write performance and uses the minimum number of drives (two) for RAID 0. It also provides a total space of
600 GB (300 GB x 2), which meets the requirement.
Confirm the configuration and close the secondary array.
You have completed the configuration of the storage arrays.

Explanation
The correct answer is A. Examine the application and device mute controls.
One of the possible reasons for the USB headset microphone not working is that the microphone is muted in the application or device settings. The technician should check if the mute button on the headset or the microphone icon in the application is active. If so, the technician should disable them and try to record sound again.
Some applications may also have their own settings for the microphone input. The technician should make sure that the USB headset is selected as the input device and that the volume level is appropriate. The technician can also test the microphone in different applications to see if the problem is specific to one application or not.
The other options are less likely to solve the problem, because:
*Connecting the headset to a different USB port may not make any difference if the device is already installed and recognized by the system.
*Checking the device's driver release date may not be relevant if the microphone was working before and no updates were installed recently.
*Increasing the speaker volume setting may not affect the microphone input at all, and may only make the audio playback louder.

Explanation
The screen rotation is locked. If a user's touch-screen tablet is having an issue with screen orientation, it could be due to screen rotation being locked in device settings.
If the screen rotation is locked, the touch-screen tablet will not rotate the screen when the device is turned.
This can usually be unlocked in the settings or by pressing a specific key combination. References:

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. References: CompTIA A+ Certification Exam: Core 1 - Page 159

Explanation
To resolve the issue of new memory modules not being recognized, the systems administrator should configure appropriate settings within the BIOS. This can include enabling memory mapping or setting memory speed and timings. References: CompTIA A+ Certification Exam Objectives, 220-1001 Section 1.8 Configure appropriate settings within the BIOS. If new memory modules were installed in several Windows desktops but some users are still reporting performance issues and the desktop has not recognized the new memory modules, the systems administrator should configure appropriate settings within the BIOS to help resolve this issue.
