NEW QUESTION # 301
A user wants RAID to be configured on a desktop to allow the fastest speed and maximum storage capacity. Which of the following RAID types should a technician configure to accommodate this request?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
RAID 0 is a configuration that stripes data across multiple disks without parity or redundancy. It provides the fastest speed and maximum storage capacity among the RAID types listed, but it also has no fault tolerance. RAID 1 mirrors data across two disks, providing redundancy but halving the storage capacity. RAID 5 stripes data across three or more disks with parity, providing fault tolerance but reducing the storage capacity by one disk. RAID 10 combines mirroring and striping across four or more disks, providing both speed and redundancy but reducing the storage capacity by half.
NEW QUESTION # 302
When a user's workstation is turned on, a message displays indicating that the date and time are incorrect.
Other computers on the network do not display this message. Which of the following is the most likely cause of this issue?
- A. The time server is misconfigured.
- B. The CPU is slow.
- C. The CMOS battery is discharged.
- D. The BIOS is not updated.
Answer: C
Explanation:
A discharged CMOS battery often causes a system to lose track of time and date settings when powered off, as this battery powers the real-time clock. The BIOS settings, including time and date, revert when this battery fails. Option A (time server misconfiguration) would impact multiple devices. BIOS updates (Option B) and CPU performance (Option D) are unrelated to timekeeping issues, as outlined in CompTIA A+ Core 1 (220-
1101) exam objectives under hardware troubleshooting.

NEW QUESTION # 305
Users report that all copies produced on a copter have a solid black line, but printing is unaffected. Which of the following is the MOST likely cause?
- A. Bad output tray
- B. Damaged (user
- C. Failing imaging drum
- D. A scratch on the scanning bed
Answer: D
Explanation:
Explanation
A scratch on the scanning bed of a copier can cause a solid black line to appear on all copies, as the scanner cannot read the original document properly through the scratch. The scratch can also reflect light and create noise in the scanned image. The printing function is unaffected by the scratch, as it does not use the scanning bed. The technician should inspect and clean the scanning bed, and replace it if necessary. Reference:

NEW QUESTION # 306
An organization is looking to upgrade the processing ability for its computers. Most users report that whenever multiple applications are being utilized, the system's response time slows down drastically. When only one application is open, the response time is acceptable. Which of the following should be upgraded FIRST?
- A. HDD
- B. SSD
- C. CPU
- D. RAM
Answer: D
Explanation:
The component that should be upgraded first is the RAM. When multiple applications are being utilized, the system's response time slows down drastically. This is because the computer is running out of memory. Upgrading the RAM will allow the computer to store more data in memory, which will improve performance when multiple applications are being used123.
NEW QUESTION # 307
A network engineer recently deployed a new application server in a cloud environment. Which of the following should be implemented to prevent a single point of failure within the system?
- A. High availability
- B. RAID
- C. Shared resources
- D. Rapid elasticity
Answer: A
Explanation:
High availability is a design principle that ensures a system or service can operate continuously without significant downtime or disruption. High availability can be achieved by implementing redundancy, failover, load balancing, and backup strategies. High availability can prevent a single point of failure within the system, which means that if one component fails, another one can take over its function. Rapid elasticity is the ability to scale up or down the resources of a system according to the demand, but it does not prevent a single point of failure. RAID is a method of storing data across multiple disks to provide redundancy and performance, but it does not prevent a single point of failure at the server level. Shared resources are the resources that are pooled and accessed by multiple users or systems, but they do not prevent a single point of failure either.

NEW QUESTION # 308
A user receives the following error when trying to reboot a computer:
Which of the following is the MOST likely cause of this error message?
- A. Faulty RAID controller
- B. Failed hard drive
- C. Incorrect storage device driver
- D. Corrupted bootloader
Answer: B
Explanation:
The error message "Reboot and Select Proper Boot Device" indicates that the computer cannot find the boot device that contains the operating system12. This can happen if the hard drive that stores the operating system is damaged or failed, and the BIOS cannot detect it or read from it23. A failed hard drive can also cause other symptoms such as clicking noises, corrupted files, or slow performance4.

NEW QUESTION # 312
Which of the following best describes the concept of a DHCP lease?
- A. A temporary assignment of an IP configuration to a device on the network
- B. A translation of network names to IP addresses for a device on the network
- C. A definition of the scope of addresses to be assigned to a device on the network
- D. A reservation of an IP configuration for a device on the network
Answer: A
Explanation:
A DHCP lease is a temporary assignment of an IP address and other network configuration parameters (such as DNS and gateway) to a device. The lease is renewed periodically to maintain the assignment.
* Why Not A (A definition of the scope of addresses): The DHCP scope defines the range of IP addresses but is not the lease itself.
* Why Not B (A reservation of an IP configuration): DHCP reservations ensure a specific device always receives the same IP address, but this is not the lease.
* Why Not D (A translation of network names to IP addresses): This describes DNS, not DHCP.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.6, DHCP concepts.
NEW QUESTION # 313
A technician is preparing to set up a gaming computer with the following components:
* Discrete, high-end graphics card
* Video capture card
* High-end processor
* Multiple hard drives
* USB 3.0 hub
* Sound card
Which of the following options is the most important for the technician to consider before building the gaming computer?
- A. Modular power supply
- B. 20-pin vs. 24-pin power adapter
- C. Redundant power supply
- D. Power supply wattage rating
Answer: D
Explanation:
The correct answer is D. Power supply wattage rating.
The power supply wattage rating is the most important factor to consider before building a gaming computer, as it determines how much power the system can draw from the wall and how much power the components can consume. A power supply with a low wattage rating may not be able to support the high-end graphics card, processor, and other devices, resulting in poor performance, instability, or damage12.
To find the optimal power supply wattage rating for a gaming computer, the technician should calculate the total power consumption of all the components and add some headroom for future upgrades or overclocking.
The technician can use online calculators such as Cooler Master Power Calculator or Seasonic Wattage Calculator to estimate the power requirements of the system3.

NEW QUESTION # 317
A user is installing a new display on a desktop computer that only has a single DVI port for video input and a single HDMI port tot video output Which of me following does the technician need to complete the setup?
- A. DigitaMo-analog converter
- B. DVI to HDMI cable
- C. DisplayPort to HDMI adapter
- D. A/v switcher
Answer: B
Explanation:
Explanation
The technician will need to connect the DVI port on the computer to the new display's HDMI port. To do this, a DVI to HDMI cable will be needed. This type of cable will allow the computer's DVI video signal to be transmitted to the new display's HDMI port.
A digital-to-analog converter (DAC) is used to convert a digital signal to an analog signal. An A/V switcher is used to switch between multiple audio and video sources and display them on a single monitor or display. A DisplayPort to HDMI adapter is used to convert a DisplayPort signal to an HDMI signal, but it is not necessary in this scenario as the computer has a DVI port and not a DisplayPort.
