Free A+ Core 1 Practice Questions (With Answers)
5 real questions from the A+ Core 1 bank, with the full explanation for each answer. No sign-up needed to read them.
- Question 1Hardware [RAM Characteristics]
The owner of a small e-sports lounge is ordering parts for a new flagship gaming desktop that will stream and record gameplay simultaneously. Budget is not a concern, and the motherboard has not yet been chosen. The technician is asked to install the fastest, latest-generation RAM available. Which of the following technologies will the technician most likely select?
- A.DDR4
- B.DDR3
- C.DDR2
- D.DDR5
Show answer and explanation
Correct answer: D
Correct. DDR5 is the latest generation of Double Data Rate Synchronous Dynamic Random-Access Memory. It offers the highest speeds and bandwidth, making it the most appropriate choice for a new, performance-intensive gaming computer to ensure maximum performance with modern CPUs and motherboards.
Why the other options are wrong
A. Incorrect. DDR4 is the previous generation; DDR5 delivers higher bandwidth and speed for a modern gaming build.
B. Incorrect. DDR3 is two generations behind DDR5 and far slower; it is not used in new performance desktops.
C. Incorrect. DDR2 is obsolete and unsupported on modern gaming motherboards.
- Question 2Hardware and Network Troubleshooting [Motherboard Issues]
A user's computer displays the wrong time. The user tries turning the computer off and on, but the time is still incorrect. The user then changes the time in the system settings, which fixes it momentarily, but the time is wrong again after a day. Which of the following is most likely causing the issue?
- A.Unseated RAM
- B.Power cable
- C.CMOS battery
- D.Video card
Show answer and explanation
Correct answer: C
Correct. The CMOS battery on the motherboard provides power to the CMOS chip, which stores the BIOS/UEFI settings, including the system date and time, when the computer is turned off. When this battery fails, the system loses its time every time it is powered down.
Why the other options are wrong
A. Incorrect. Unseated or faulty RAM would typically cause boot failures, POST beep codes, or system instability (BSODs), not an incorrect system time.
B. Incorrect. A faulty power cable would prevent the computer from turning on or cause it to shut down unexpectedly. It would not affect the system's ability to keep time when powered off.
D. Incorrect. A faulty video card would cause display issues, such as artifacts, a blank screen, or driver crashes. It has no role in maintaining the system time.
- Question 3Hardware and Network Troubleshooting [Printer Issues]
A user sends a large print job to a network printer, but nothing prints. Other users are also unable to print. The technician checks the printer's queue on the print server and sees the user's job is stuck at the top of the queue with a status of 'Printing'. What is the first step the technician should take?
- A.Replace the network print server
- B.Power cycle the printer and workstation to clear temporary errors in the print queue
- C.Cancel the stuck print job and restart the print spooler service on the print server
- D.Replace the printer toner cartridge
Show answer and explanation
Correct answer: C
Correct. A corrupted or stuck print job can block the entire print queue. The standard procedure is to first try to cancel the job. If it won't cancel, the next step is to stop and restart the 'Print Spooler' service on the computer managing the queue (in this case, the print server). This will clear the queue and allow other jobs to print.
Why the other options are wrong
A. Incorrect. Replacing the print server is a drastic hardware step; the stuck job in the queue points to a software issue that can be cleared without replacing anything.
B. Incorrect. While this may be necessary, the immediate problem is the stuck job on the server, which will prevent any further jobs from being sent to the printer.
D. Incorrect. A toner issue would not cause a job to get stuck in the server's queue.
- Question 4Hardware and Network Troubleshooting [Network Issues]
A user reports they can access some websites but not others. A technician pings the user's default gateway and gets a successful reply. They then ping a public IP address (8.8.8.8) and also get a successful reply. What is the most likely cause of the user's issue?
- A.A faulty network cable
- B.An incorrect default gateway address
- C.A DNS server issue
- D.The user's computer does not have an IP address
Show answer and explanation
Correct answer: C
Correct. The ability to reach a public IP address proves that internet connectivity is working. The inability to reach some websites by name points to a problem with DNS resolution. The configured DNS server may be down or unable to resolve certain domains.
Why the other options are wrong
A. Incorrect. The successful pings to both the local gateway and a public IP confirm that the physical connection is working.
B. Incorrect. The successful ping to the gateway's IP address confirms it is correct and reachable.
D. Incorrect. The computer must have a valid IP address to be able to send pings successfully.
- Question 5Hardware and Network Troubleshooting [USB Power]
An external USB hard drive works when connected to a desktop PC but not when connected to a laptop. What is the MOST likely cause?
- A.The laptop's USB port is broken and needs to be replaced on the motherboard
- B.The laptop's USB port provides insufficient power
- C.The drive is incompatible with laptops due to file system formatting differences
- D.The laptop needs a driver update from the manufacturer to recognize the external enclosure
Show answer and explanation
Correct answer: B
Correct. External hard drives require significant power. Laptop USB ports may not supply enough current. A powered USB hub can solve this.
Why the other options are wrong
A. Incorrect. Before assuming port failure, power delivery should be considered, especially for power-hungry devices.
C. Incorrect. USB drives are universally compatible. Power delivery differences between desktop and laptop ports is the more likely issue.
D. Incorrect. USB storage uses standard drivers. Power insufficiency is the more common cause of this specific symptom.
