Which of the following storage options would a technician most likely recommend to have large amounts of affordable capacity without concern for read times on a desktop computer?
- A . 750GB NVMe M.2 SSD
- B . 2x 1TB PCIe SSD in RAID 1
- C . 2TB SATA 3.5" 5,400rpm HDD
- D . 4TB SAS 2.5" 15,000rpm HDD
C
Explanation:
If performance is not a primary concern and the user requires large, cost-effective storage, a2TB 5400rpm SATA HDDis ideal. It offers high capacity at a lower price point than SSDs and faster HDDs.
Option A: NVMe drives offer exceptional speed but are significantly more expensive per GB and not necessary when read/write speed is not a concern.
Option B: RAID 1 improves redundancy but cuts usable capacity in half and uses expensive SSDs.
Option D: SAS drives are fast and reliable but are enterprise-grade and expensive ― overkill for desktop use.

Which of the following is designed to be used in commercial spaces?
- A . USB 3.1 Gen 2
- B . Straight tip fiber connector
- C . Plenum cabling
- D . Cat 8
C
Explanation:
Plenum cabling is designed for use in commercial spaces where cables run through air ducts or plenum spaces, as it has fire-resistant properties and emits less toxic smoke.
Why Not A (USB 3.1 Gen 2): USB is for peripheral connections, not large-scale commercial installations.
Why Not B (Straight tip fiber connector): Fiber connectors are for high-speed connections but are not specifically for commercial spaces.
Why Not D (Cat 8): While Cat 8 is high-speed, it is not uniquely suited for commercial spaces like plenum cabling.

A computer is experiencing random shutdowns. A technician notices that the fans on the computer work but are noisy. The CPU temperature is about 122°F (50°C) when the computer is started but rises to 208°F (98°C) when applications are opened.
Which of the following would most likely fix this issue?
- A . Replacing the power supply
- B . Installing a high-performance heat sink
- C . Adjusting the fan settings
- D . Adding more RAM to the computer
B
Explanation:
Excessive heat buildup due to insufficient cooling is a primary cause of unexpected shutdowns. A high-performance heat sink improves thermal transfer, dissipates more heat, and helps maintain CPU temperature within safe limits. When CPU temperatures reach levels like 208°F (98°C), the system may shut down to prevent damage.
Reference: "CompTIA A+ Complete Study Guide" by Quentin Docter C Chapter 1, pages 68C71, discusses CPU cooling and heat sink improvements.
The display in a conference room has a ghost image that does not match the presentation.
Which of the following would test resolve the issue?
- A . Adjust the color settings.
- B . Correct the keystone.
- C . Increase the brightness levels
- D . Replace the monitor.
B
Explanation:
B. Correct the keystone:
A keystone correction adjusts the image shape when a projector is angled either up or down. When a projector is not positioned directly perpendicular to the screen, the image becomes distorted or offset. Correcting the keystone will resolve alignment issues, ensuring that the presentation matches the display.
Incorrect Options:
A technician needs to select PC components with a minimal number of visible internal cables.
Which of the following should the technician use?
- A . SATA drive connections
- B . Liquid cooling
- C . Modular power supply
- D . Wireless NIC
C
Explanation:
A modular power supply allows a technician to connect only the power cables that are needed, reducing clutter and improving airflow. This is ideal when aiming for a clean build with minimal visible internal cables.
Option A (SATA drive connections): Still require both power and data cables, adding to cable count.
Option B (Liquid cooling): May reduce some bulk from large air coolers, but adds tubing and still needs cabling.
Option D (Wireless NIC): Adds wireless capability but has no relation to internal cabling cleanliness.

A company wants to have fast read speeds for its locally stored data.
Which of the following configurations has the lowest cost to fulfill this requirement?
- A . RAID 0
- B . RAID 1
- C . RAID 5
- D . RAID 10
A
Explanation:
RAID 0 (striping) provides the fastest read (and write) speeds at the lowest cost, as all disk capacity is used for storage and performance. However, it offers no redundancy.
From CompTIA A+ 220-1101 Official Study Guide, Objective 3.4 C RAID types:
"RAID 0 stripes data across multiple disks, offering the best performance and lowest cost but no fault tolerance."

A technician is working on a RAID 1 array that is apparently degraded. The technician verifies the RAM and power are both operating as expected.
Which of the following can the technician do to further isolate the issue?
- A . Perform individual drive diagnostics.
- B . Run the chkdsk /i command.
- C . Rebuild the RAID array.
- D . Reconfigure the array as RAID 0.
A
Explanation:
A degraded RAID 1array usually means one of the drives has failed or is failing. The correct next step is to run diagnostics on each drive to identify the faulty one. RAID 1 uses mirroring, so one good drive should still contain all the data.
Option B: chkdsk checks file system integrity, not hardware drive health.
Option C: Rebuilding should only occurafteridentifying and replacing a faulty drive.
Option D: RAID 0 offers no redundancy and would destroy data in this context. CompTIA A+ Core 1 Exam Objective

When installing a network printer, a technician needs to ensure the printer is available after a network is restarted.
Which of the following should the technician set up on the printer to meet this requirement?
- A . Static IP address
- B . Private address
- C . Wi-Fi on the printer
- D . Dynamic addressing
A
Explanation:
Assigning astatic IP address to a network printer ensures it always retains the same address, allowing users and print servers to consistently reach it even after a reboot or network refresh.
Option B (Private address): Refers to address ranges (e.g., 192.168.x.x) ― doesn’t guarantee address persistence.
Option C (Wi-Fi): Is a connection method, not a method of IP assignment.
Option D (Dynamic addressing): Via DHCP, which can change over time unless reservations are made (less reliable).

A technician recently updated the firmware on a dual-BIOS motherboard. Following the update, the system has been stuck in a boot loop and cannot start an OS from any internal or external device. The technician cannot access the UEFI menu either.
Which of the following should the technician do next?
- A . Enable the secondary configuration.
- B . Downgrade the firmware via USB.
- C . Start a warranty repair of the motherboard.
- D . Reapply thermal paste to the CPU.
A
Explanation:
Dual-BIOS motherboards contain two firmware chips. If the primary BIOS becomes corrupted, the system can failover to the secondary BIOS. Most boards allow manual enabling of the secondary BIOS via a physical switch or jumper.
Option B: Downgrading firmware may not be possible if the system won’t POST or access UEFI.
Option C: Not necessary until both BIOS chips are non-functional.
Option D: Thermal paste affects heat dissipation, not BIOS/boot behavior.

A user prints a job from a laser printer. The user wipes the page, and the words and images come off of it. The technician replaces the toner cartridge, but the issue persists.
Which of the following components should the technician replace next?
- A . Fuser
- B . Drum
- C . Developer roller
- D . Discharge lamp
A
Explanation:
In laser printers, the fuser unit is responsible formelting the toner onto the paper using heat and pressure. If the toner rubs off easily, it’s a clear sign the fuser is failing or not heating properly. Replacing the fuser will ensure the toner bonds correctly to the paper.
Option B (Drum): Transfers the image, but doesn’t fuse the toner.
Option C (Developer roller): Applies toner to the drum ― wouldn’t cause toner to rub off.
Option D (Discharge lamp): Prepares the drum for a new image; not related to toner adhesion. CompTIA A+ Core 1 Exam Objective
